Subject: [PATCH 001/771] [lldb/Test] Fix missing yaml2obj in Xcode standalone
 build.

Rather than trying to find the yaml2obj from dotest we should pass it in
like we do for dsymutil and FileCheck.

Subject: [PATCH 002/771] [OpenMP][CUDA] Fix std::complex in GPU regions

The old way worked to some degree for C++-mode but in C mode we actually
tried to introduce variants of macros (e.g., isinf). To make both modes
work reliably we get rid of those extra variants and directly use NVIDIA
intrinsics in the complex implementation. While this has to be revisited
as we add other GPU targets which want to reuse the code, it should be
fine for now.

Subject: [PATCH 004/771] [OpenMP][NFC] Remove unused (always fixed) arguments

There are various runtime calls in the device runtime with unused, or
always fixed, arguments. This is bad for all sorts of reasons. Clean up
two before as we match them in OpenMPOpt now.

Subject: [PATCH 007/771] [OpenMP] Identify GPU kernels (aka. OpenMP target
 regions)

We now identify GPU kernels, that is entry points into the GPU code.
These kernels (can) correspond to OpenMP target regions. With this patch
we identify and on request print them via remarks.

Subject: [PATCH 008/771] [OpenMP] Compute a proper module slice for the CGSCCC
 pass

The module slice describes which functions we can analyze and transform
while working on an SCC as part of the CGSCC OpenMPOpt pass. So far, we
simply restricted it to the SCC. In a follow up we will need to have a
bigger scope which is why this patch introduces a proper identification
of the module slice. In short, everything that has a transitive
reference to a function in the SCC or is transitively referenced by one
is fair game.

Subject: [PATCH 009/771] [OpenMP] Replace function pointer uses in GPU state
 machine

In non-SPMD mode we create a state machine like code to identify the
parallel region the GPU worker threads should execute next. The
identification uses the parallel region function pointer as that allows
it to work even if the kernel (=target region) and the parallel region
are in separate TUs. However, taking the address of a function comes
with various downsides. With this patch we will identify the most common
situation and replace the function pointer use with a dummy global
symbol (for identification purposes only). That means, if the parallel
region is only called from a single target region (or kernel), we do not
use the function pointer of the parallel region to identify it but a new
global symbol.

Fixes PR46450.

Subject: [PATCH 011/771] [OpenMP][FIX] remove unused variable and long if-else
 chain

MSVC throws an error if you use "too many" if-else in a row:
  `Frontend/OpenMP/OMPKinds.def(570): fatal error C1061: compiler limit:
    blocks nested too deeply`
We work around it now...

Subject: [PATCH 012/771] [clang-tidy] Reworked enum options handling(again)

Reland b9306fd after fixing the issue causing mac builds to fail unittests.

Following on from D77085, I was never happy with the passing a mapping to the option get/store functions. This patch addresses this by using explicit specializations to handle the serializing and deserializing of enum options.

Subject: [PATCH 018/771] [TRE] allow TRE for non-capturing calls.

The current implementation of Tail Recursion Elimination has a very restricted
pre-requisite: AllCallsAreTailCalls. i.e. it requires that no function
call receives a pointer to local stack. Generally, function calls that
receive a pointer to local stack but do not capture it - should not
break TRE. This fix allows us to do TRE if it is proved that no pointer
to the local stack is escaped.

Subject: [PATCH 019/771] [AMDGPU] Move LowerSwitch pass to CodeGenPrepare.

It is possible that LowerSwitch pass leaves certain blocks
unreachable from the entry. If not removed, these dead blocks
can cause undefined behavior in the subsequent passes.
It caused a crash in the AMDGPU backend after the instruction
selection when a PHI node has its incoming values coming from
these unreachable blocks.

In the AMDGPU pass flow, the last invocation of UnreachableBlockElim
precedes where LowerSwitch is currently placed and eventually
missed out on the opportunity to get these blocks eliminated.
This patch ensures that LowerSwitch pass get inserted earlier
to make use of the existing unreachable block elimination pass.

Subject: [PATCH 021/771] [fix-irreducible] Skip unreachable predecessors.

Summary:
- Skip unreachable predecessors during header detection in SCC. Those
  unreachable blocks would be generated in the switch lowering pass in
  the corner cases or other frontends. Even though they could be removed
  through the CFG simplification, we should skip them during header
  detection.

Subject: [PATCH 024/771] [flang][openmp] Check clauses allowed semantic with
 tablegen generated map

Summary:
This patch is enabling the generation of clauses enum sets for semantics check in Flang through
tablegen. Enum sets and directive - sets map is generated by the new tablegen infrsatructure for OpenMP
and other directive languages.
The semantic checks for OpenMP are modified to use this newly generated map.

Subject: [PATCH 029/771] [X86] Add test cases for missed opportunities to use
 vpternlog due to a bitcast between the logic ops.

These test cases fail to use vpternlog because the AND was converted
to a blend shuffle and then converted back to AND during shuffle lowering.
This results in the AND having a different type than it started with.
This prevents our custom matching logic from seeing the two logic ops.

Subject: [PATCH 038/771] [Windows SEH] Fix the frame-ptr of a nested-filter
 within a _finally

This change fixed a SEH bug (exposed by test58 & test61 in MSVC test xcpt4u.c);
when an Except-filter is located inside a finally, the frame-pointer generated today
via intrinsic @llvm.eh.recoverfp is the frame-pointer of the immediate
parent _finally, not the frame-ptr of outermost host function.

The fix is to retrieve the Establisher's frame-pointer that was previously saved in
parent's frame.
The prolog of a filter inside a _finally should be like code below:

%0 = call i8* @llvm.eh.recoverfp(i8* bitcast (@"?fin$0@0@main@@"), i8*%frame_pointer)
%1 = call i8* @llvm.localrecover(i8* bitcast (@"?fin$0@0@main@@"), i8*%0, i32 0)
%2 = bitcast i8* %1 to i8**
%3 = load i8*, i8** %2, align 8

Subject: [PATCH 039/771] [DAGCombiner] tighten fast-math constraints for fma
 fold

fadd (fma A, B, (fmul C, D)), E --> fma A, B, (fma C, D, E)

This is only allowed when "reassoc" is present on the fadd.

As discussed in D80801, this transform goes beyond
what is allowed by "contract" FMF (-ffp-contract=fast).
That is because we are fusing the trailing add of 'E' with a
multiply, but without "reassoc", the code mandates that the
products A*B and C*D are added together before adding in 'E'.

I've added this example to the LangRef to try to clarify the
meaning of "contract". If that seems reasonable, we should
probably do something similar for the clang docs because
there does not appear to be any formal spec for the behavior
of -ffp-contract=fast.

Subject: [PATCH 044/771] BPF: permit .maps section variables with typedef type

Currently, llvm when see a global variable in .maps section,
it ensures its type must be a struct type. Then pointee
will be further evaluated for the structure members.
In normal cases, the pointee type will be skipped.

Although this is what current all bpf programs are doing,
but it is a little bit restrictive. For example, it is legitimate
for users to have:
typedef struct { int key_size; int value_size; } __map_t;
__map_t map __attribute__((section(".maps")));

This patch lifts this restriction and typedef of
a struct type is also allowed for .maps section variables.
To avoid create unnecessary fixup entries when traversal
started with typedef/struct type, the new implementation
first traverse all map struct members and then traverse
the typedef/struct type. This way, in internal BTFDebug
implementation, no fixup entries are generated.

Two new unit tests are added for typedef and const
struct in .maps section. Also tested with kernel bpf selftests.

Subject: [PATCH 045/771] [LV] Fixing versioning-for-unit-stide of loops with
 small trip count

This patch fixes D81345 and PR46652.

If a loop with a small trip count is compiled w/o -Os/-Oz, Loop Access Analysis
still generates runtime checks for unit strides that will version the loop.

In such cases, the loop vectorizer should either re-run the analysis or bail-out
from vectorizing the loop, as done prior to D81345. The latter is applied for
now as the former requires refactoring.

Subject: [PATCH 047/771] [X86] Fix two places that appear to misuse
 peekThroughOneUseBitcasts

peekThroughOneUseBitcasts checks the use count of the operand of the bitcast. Not the bitcast itself. So I think that means we need to do any outside haseOneUse checks before calling the function not after.

I was working on another patch where I misused the function and did a very quick audit to see if I there were other similar mistakes.

Subject: [PATCH 048/771] [X86] Consistently use 128 as the PSHUFB/VPPERM index
 for zero

Bit 7 of the index controls zeroing, the other bits are ignored when bit 7 is set. Shuffle lowering was using 128 and shuffle combining was using 255. Seems like we should be consistent.

This patch changes shuffle combining to use 128 to match lowering.

Subject: [PATCH 051/771] Revert "[Matrix] Tighten LangRef definitions and
 Verifier checks."

This reverts commit f4d29d6e8c43cfd924d9d7cc1ac0c269b2788e75.

Hm, some build bot failures, reverting it while I investigate that.

Subject: [PATCH 052/771] [InstCombine] fold mul of zext/sext bools to 'and'

Similar to rG40fcc42:
The base case only worked because we were relying on a
poison-unsafe select transform; if that is fixed, we
would regress on patterns like this.

The extra use tests show that the select transform can't
be applied consistently. So it may be a regression to have
an extra instruction on 1 test, but that result was not
created safely and does not happen reliably.

Subject: [PATCH 053/771] [X86] Add CPU name strings to
 getIntelProcessorTypeAndSubtype and getAMDProcessorTypeAndSubtype in
 compiler-rt.

These aren't used in compiler-rt, but I plan to make a similar
change to the equivalent code in Host.cpp where the mapping from
type/subtype is an unnecessary complication. Having the CPU strings
here will help keep the code somewhat synchronized.

From ea84dc9500df383b4fe07199134033f358411e59 Mon Sep 17 00:00:00 2001

Subject: [PATCH 054/771] [X86] Add CPU string output to
 getIntelProcessorTypeAndSubtype/getAMDProcessorTypeAndSubtype in Host.cpp

Rather than converting type/subtype into strings, just directly
select the string as part of family/model decoding. This avoids
the need for creating fake Type/SubTypes for CPUs not supported
by compiler-rtl. I've left the Type/SubType in place where it matches
compiler-rt so that the code can be diffed, but the Type/SubType
is no longer used by Host.cpp.

compiler-rt was already updated to select strings that aren't used
so the code will look similar.

 getHostCPUName.

For model 6 CPUs, we have a fallback detection method based on
available features. That mechanism should be enough to detect
these early family 6 CPUs as they only differ in the features
used by the detection anyway.

Subject: [PATCH 056/771] [mlir][ODS] Add support for specifying the namespace
 of an interface.

The namespace can be specified using the `cppNamespace` field. This matches the functionality already present on dialects, enums, etc. This fixes problems with using interfaces on operations in a different namespace than the interface was defined in.

Subject: [PATCH 058/771] Bump the default target CPU for i386-freebsd to i686

Summary:
Similar to what we have done downstream, some time ago:
https://svnweb.freebsd.org/changeset/base/353936

This followed some discussions on the freebsd-arch mailing lists, and
most people agreed that it was a better default, and also it worked
around several issues where clang generated libcalls to 64 bit atomic
primitives, instead of using cmpxchg8b.

Subject: [PATCH 060/771] [clang] Add -Wsuggest-override

This patch adds `-Wsuggest-override`, which allows for more aggressive enforcement of modern C++ best practices, as well as better compatibility with gcc, which has had its own `-Wsuggest-override` since version 5.1.

Clang already has `-Winconsistent-missing-override`, which only warns in the case where there is at least one function already marked `override` in a class. This warning strengthens that warning by suggesting the `override` keyword regardless of whether it is already present anywhere.

The text between suggest-override and inconsistent-missing-override is now shared, using `TextSubstitution` for the entire diagnostic text.

Subject: [PATCH 061/771] [X86] Rename
 X86_CPU_TYPE_COMPAT_ALIAS/X86_CPU_TYPE_COMPAT/X86_CPU_SUBTYPE_COMPAT macros.
 NFC

Remove _COMPAT. Drop the ARCHNAME. Remove the non-COMPAT versions
that are no longer needed.

We now only use these macros in places where we need compatibility
with libgcc/compiler-rt. So we don't need to call out _COMPAT
specifically.

Subject: [PATCH 062/771] Rename/refactor isIntegerConstantExpression to
 getIntegerConstantExpression

There is a version that just tests (also called
isIntegerConstantExpression) & whereas this version is specifically used
when the value is of interest (a few call sites were actually refactored
to calling the test-only version) so let's make the API look more like
it.

Subject: [PATCH 063/771] Revert "Rename/refactor isIntegerConstantExpression
 to getIntegerConstantExpression"

Broke buildbots since I hadn't updated this patch in a while. Sorry for
the noise.

This reverts commit 49e5f603d40083dce9c05796e3cde3a185c3beba.

Subject: [PATCH 068/771] [InstCombine] Improve select -> phi canonicalization:
 consider more blocks

We can try to replace select with a Phi not in its parent block alone,
but also in blocks of its arguments. We benefit from it when select's
argument is a Phi.

Subject: [PATCH 074/771] [clang][RecoveryExpr] Clarify the dependence-bits
 documentation.

The expr dependent-bits described that the expression somehow
depends on a template paramter.

With RecoveryExpr, we have generalized it to "the expression depends on
a template parameter, or an error".  This patch updates/cleanups all related
comments of dependence-bits.

Subject: [PATCH 076/771] [clang] Include type specifiers in typo correction
 when checking isCXXDeclarationSpecifiers.

- add more tests (the test added in https://github.com/llvm/llvm-project/commit/2f448467e4254ddc3191136c968e6054bc009b88 is weak);
- improve the `MyTemplate<type_typo, int>();` case, with this patch, typo correction
  suggests the type decl, and no regressions found.

Subject: [PATCH 078/771] [mlir][VectorOps] Lower vector.fma to llvm.fmuladd
 instead of llvm.fma

Summary:
These are semantically equivalent, but fmuladd allows decaying the op
into fmul+fadd if there is no fma instruction available. llvm.fma lowers
to scalar calls to libm fmaf, which is a lot slower.

Subject: [PATCH 079/771] [OpenCL] Defer addr space deduction for dependent
 type.

This patch removes deduction of address spaces in parsing
for types that depend on template parameter even if an
address space is already known. Deducing it early interferes
with template instantiation/specialization logic that uses
source address space where address space is not present.

Address space deduction for templates is therefore fully
moved to the template instantiation/specialization phase.

Patch by Ole Strohm (olestrohm)!

Subject: [PATCH 080/771] [LLD][ELF] -  Allow relocation sections to appear
 before their target sections.

It allows handling cases when we have SHT_REL[A] sections before target
sections in objects.

This fixes https://bugs.llvm.org/show_bug.cgi?id=46632

which says: "Normally it is not what compilers would emit. We have to support it,
because some custom tools might want to use this feature, which is not restricted by ELF gABI"

Subject: [PATCH 083/771] [lldb][NFC] Remove misleading class_language variable
 in DWARFASTParserClang

There is a local 'class_language' veriable in DWARFASTParserClang which is named
as if it is related to the 'class_language' member of ParsedDWARFTypeAttributes.
However, it actually only has two possible enum values: 'ObjC' (which means the
current record is a Objective-C class) or 'Unknown' (which covers all other
cases).

This is confusing for the reader and also lead to some strange code where we
have several comparisons against the value "ObjC_plus_plus" (which is always
false).

This replaces the variable with either a const bool variable (if there are
multiple checks for that condition in a function) or a direct call to the
TypeSystemClang utility method for checking if it's a Objective-C
Object/Interface type.

Subject: [PATCH 086/771] [llvm-readobj] - Add a generic test for
 --dyn-relocations and fix an issue.

We have an issue currently: --dyn-relocations always prints the following
relocation header when dumping `DynPLTRelRegion`:

"Offset  Info  Type Symbol's Value  Symbol's Name + Addend"

I.e. even for an empty object, --dyn-relocations still prints this.
It is a easy to fix bug, but we have no dedicated test case for this option.
(we have a dynamic-reloc-no-section-headers.test, which has a slightly different purpose).

This patch adds a test and fixes the behavior.

Subject: [PATCH 088/771] [COFF] Error on unexpected .pdata size

Previously, lld would crash if the .pdata size was not an even multiple
of the expected .pdata entry size. This makes it error gracefully instead.

(We hit this in Chromium due to an assembler problem: https://crbug.com/1101577)

Subject: [PATCH 091/771] [ARM][MVE] Refactor option
 -disable-mve-tail-predication

This refactors option -disable-mve-tail-predication to take different arguments
so that we have 1 option to control tail-predication rather than several
different ones.

This is also a prep step for D82953, in which we want to reject reductions
unless that is requested with this option.

Subject: [PATCH 092/771] [DAGCombiner] allow load/store merging if pairs can
 be rotated into place

This carves out an exception for a pair of consecutive loads that are
reversed from the consecutive order of a pair of stores. All of the
existing profitability/legality checks for the memops remain between
the 2 altered hunks of code.

This should give us the same x86 base-case asm that gcc gets in
PR41098 and PR44895:i
http://bugs.llvm.org/PR41098
http://bugs.llvm.org/PR44895

I think we are missing a potential subsequent conversion to use "movbe"
if the target supports that. That might be similar to what AArch64
would use to get "rev16".

Subject: [PATCH 094/771] [DAGCombiner] allow load/store merging if pairs can
 be rotated into place

This carves out an exception for a pair of consecutive loads that are
reversed from the consecutive order of a pair of stores. All of the
existing profitability/legality checks for the memops remain between
the 2 altered hunks of code.

This should give us the same x86 base-case asm that gcc gets in
PR41098 and PR44895:
http://bugs.llvm.org/PR41098
http://bugs.llvm.org/PR44895

I think we are missing a potential subsequent conversion to use "movbe"
if the target supports that. That might be similar to what AArch64
would use to get "rev16".

Subject: [PATCH 097/771] [yaml2obj] - Refactor header-sh-fields.yaml test.

This refines the test to use macros. It is needed for
a follow-up change that adds a functionality to
override more fields.

Also, it is just cleaner to test each key separately.

Subject: [PATCH 100/771] [SLPVectorizer] handle vectorizeable library
 functions

Teaches the SLPVectorizer to use vectorized library functions for
non-intrinsic calls.

This already worked for intrinsics that have vectorized library
functions, thanks to D75878, but schedules with library functions with a
vector variant were being rejected early.

-   assume that there are no load/store dependencies between lib
    functions with a vector variant; this would otherwise prevent the
    bundle from becoming "ready"

-   check during legalization that the vector variant can be used

-   fix-up where we previously assumed that a call would be an intrinsic

Subject: [PATCH 102/771] [lldb/dotest] Remove the "xunit" result formatter

Summary:
My understanding is that this was added to make dotest interact well
with the GreenDragon bots, back when dotest was the main test driver.
Now that everything goes through lit (which has its own xunit
formatter), it seems largely irrelevant.

There are more cleanups that can be done after removing this be done
here, but this should be enough to test the waters.

Subject: [PATCH 103/771] [ms] [llvm-ml] Improve MASM STRUCT field accessor
 support

Summary:
Adds support for several accessors:
- `[<identifier>.<struct name>].<field>`
- `[<identifier>.<struct name>.<field>].<subfield>` (where `field` has already-defined STRUCT type)
- `[<variable>.<field>].<subfield>` (where `field` has already-defined STRUCT type)

Subject: [PATCH 105/771] [compiler-rt][CMake] Pass down LLVM_LIT_ARGS in
 runtime build

We should also pass down the LLVM_LIT_ARGS in runtime build mode,
so that the runtime tests can be well controlled as well.

We actually passed this down in clang/runtime/CMakeLists.txt
But not for calls from llvm/runtime/CMakeLists.txt.

 field accessors: (<TYPE> PTR <value>).<field>

Summary:
Add support for MASM STRUCT casting field accessors: (<TYPE> PTR <value>).<field>

Since these are operands, we add them to X86AsmParser. If/when we extend MASM support to other architectures (e.g., ARM), we will need similar changes there as well.

Subject: [PATCH 116/771] [DAGCombiner] rot i16 X, 8 --> bswap X

We have this generic transform in IR (instcombine),
but as shown in PR41098:
http://bugs.llvm.org/PR41098
...the pattern may emerge in codegen too.

x86 has a potential refinement/reversal opportunity here,
but that should come later or needs a target hook to
avoid the transform. Converting to bswap is the more
specific form, so we should use it if it is available.

Subject: [PATCH 119/771] [JITLink] Add a synchronous version of finalize for
 convenience.

This will be used by upcoming patches that implement indirection utils
(reentry, reentry trampolines, and stubs) on top of
JITLinkMemoryManager to unify in-process and cross-process lazy
compilation support.

Subject: [PATCH 120/771] [ORC] Generalize emit re-entry, stub, etc. APIs for
 working addr != link addr.

This patch generalizes the APIs for writing re-entry blocks, trampolines and
stubs to allow their final linked address to differ from the address of
their initial working memory. This will allow these routines to be used with
JITLinkMemoryManagers, which will in turn allow for unification of code paths
for in-process and cross-process lazy JITing.

Subject: [PATCH 124/771] RISCV: Avoid GlobalISel build break in a future patch

The GlobalISelEmitter is stricter about matching timm instruction
outputs to timm inputs (although in an accidental sort of way that
doesn't hit a proper import failure error). Also, apparently no
intrinsic patterns were importing since the ID enum declaration was
missing.

Subject: [PATCH 125/771] TableGen/GlobalISel: Emit enum names for reg class ID
 instead of value

This was emitting the raw value for the reg class ID with a comment
for the actual class name. Switch to emitting the qualified enum name
instead, which obviates the need for the comment and also helps keep
the lit tests on the emitter output more stable.

Subject: [PATCH 126/771] [llvm][NFC] ML Policies: changed the saved_model
 protobuf to text

Also compacted the checkpoints (variables) to one file (plus the index).

This reduces the binary model files to just the variables and their
index. The index is very small. The variables are serialized float
arrays. When updated through training, the changes are very likely
unlocalized, so there's very little value in them being anything else
than binary.

Subject: [PATCH 141/771] [PredicateInfo] Place predicate info after assume

Place the ssa.copy instructions for assumes after the assume,
instead of before it. Both options are valid, but placing them
afterwards prevents assumes from being replaced with assume(true).
This fixes https://bugs.llvm.org/show_bug.cgi?id=37541 in NewGVN
and will avoid a similar issue in SCCP when we handle more
predicate infos.

Subject: [PATCH 142/771] [flang] Use octal escapes for character literals in
 modfiles

Character literals can be formatted using octal or hex escapes for
non-ascii characters. This is so that the program can be unparsed for
either pgf90 or gfortran to compile. But modfiles should not be affected
by that -- they should be consistent.

This changes causes modfiles to always have character literals formatted
with octal escapes.

Subject: [PATCH 148/771] [mlir][StandardToSPIRV] Fix conversion for signed
 remainder

Per the Vulkan's SPIR-V environment spec, "for the OpSRem and OpSMod
instructions, if either operand is negative the result is undefined."
So we cannot directly use spv.SRem/spv.SMod if either operand can be
negative. Emulate it via spv.UMod.

Because the emulation uses spv.SNegate, this commit also defines
spv.SNegate.

Subject: [PATCH 152/771] [MLIR] Change ODS collective params build method to
 provide an empty default value for named attributes

- Provide default value for `ArrayRef<NamedAttribute> attributes` parameter of
  the collective params build method.
- Change the `genSeparateArgParamBuilder` function to not generate build methods
  that may be ambiguous with the new collective params build method.
- This change should help eliminate passing empty NamedAttribue ArrayRef when the
  collective params build method is used
- Extend op-decl.td unit test to make sure the ambiguous build methods are not
  generated.

Original commit c60216db15132401ff60c08ccef899321f63b6b6.

The test can only run on Darwin because of how it was setup, so I'm
enforcing that.

Subject: [PATCH 155/771] [ADT] Specialize std::swap() for SetVector

This is intended to address a compile-time regression from
1eddce4177cfddc86d4696b758904443b0b4f193. A SmallPtrSet was
replaced with a SetVector there, which had an unexpected large
compile-time impact. It turns out that this structure is getting
swapped a lot, and previously this used an optimized std::swap()
specialization for SmallPtrSet. Now it ends up using the default,
triple-move based implementation, which is much more expensive.

This patch (partly) addresses the issue by specializing std::swap()
for SetVector.

Subject: [PATCH 156/771] [mlir] Add alignment attribute to LLVM memory ops and
 use in vector.transfer

Summary: The native alignment may generally not be used when lowering a vector.transfer to the underlying load/store operation. This revision fixes the unmasked load/store alignment to match that of the masked path.

Subject: [PATCH 160/771] [ubsan] Check implicit casts in ObjC for-in
 statements

Check that the implicit cast from `id` used to construct the element
variable in an ObjC for-in statement is valid.

This check is included as part of a new `objc-cast` sanitizer, outside
of the main 'undefined' group, as (IIUC) the behavior it's checking for
is not technically UB.

The check can be extended to cover other kinds of invalid casts in ObjC.

Partially addresses: rdar://12903059, rdar://9542496

Subject: [PATCH 162/771] [compiler-rt][MSAN][test] Update buffersize for UTF-8
 to C convert

This is exposed by https://reviews.llvm.org/D83486.
When the host is UTF8, we may get n >10, causing assert failure.
Increase the buffersize to support UTF-8 to C conversion.

Subject: [PATCH 164/771] Revert "[InstCombine] Drop debug loc in
 TryToSinkInstruction (reland)"

This reverts commit 9649c2095f07a392bc2b2a93b5bd6c4c9bf5ba34. See
discussion on the llvm-commits thread: if it's OK to preserve the
location when sinking a call, it's probably OK to always preserve the
location.

Subject: [PATCH 165/771] [InstCombine] Erase attribute lists for simplified
 libcalls

Currently, a transformation like pow(2.0, x) -> exp2(x) copies the pow
attribute list verbatim and applies it to exp2. This works out fine
when the attribute list is empty, but when it isn't clang may error due
due to the mismatch.

The source function and destination don't necessarily have anything
to do with one another, attribute-wise. So it makes sense to remove
the attribute lists (this is similar to what IPO does in this
situation).

This was discovered after implementing the `noundef` param attribute.

Subject: [PATCH 168/771] Lowering of OpenMP Parallel operation to LLVM IR 1/n

This patch introduces lowering of the OpenMP parallel operation to LLVM
IR using the OpenMPIRBuilder.

Functions topologicalSort and connectPhiNodes are generalised so that
they work with operations also. connectPhiNodes is also made static.

Lowering works for a parallel region with multiple blocks. Clauses and
arguments of the OpenMP operation are not handled.

Subject: [PATCH 170/771] [AssumeBundles] Use operand bundles to encode
 alignment assumptions

Summary:
NOTE: There is a mailing list discussion on this: http://lists.llvm.org/pipermail/llvm-dev/2019-December/137632.html

Complemantary to the assumption outliner prototype in D71692, this patch
shows how we could simplify the code emitted for an alignemnt
assumption. The generated code is smaller, less fragile, and it makes it
easier to recognize the additional use as a "assumption use".

As mentioned in D71692 and on the mailing list, we could adopt this
scheme, and similar schemes for other patterns, without adopting the
assumption outlining.

Subject: [PATCH 173/771] Reapply "[llvm] Native size estimator for training
 -Oz inliner"

This reverts commit 9908a3b9f521c954cbf6adcec35b14b2f6c8da49.

The fix was to exclude the content of TFUtils.h (automatically
included in the LLVM_Analysis module, when LLVM_ENABLE_MODULES is enabled).

Subject: [PATCH 175/771] MemorySanitizer: If a field is marked noundef, check
 init at call site

Adds LLVM option to control eager checking under -msan-eager-checks.
This change depends on the noundef keyword to determining cases where it
it sound to check these shadows, and falls back to passing shadows
values by TLS.

Checking at call boundaries enforces undefined behavior rules with
passing uninitialized arguments by value.

Subject: [PATCH 179/771] [builtins] Cleanup generic-file filtering

Split filter_builtin_sources into two functions:
 - filter_builtin_sources that removes generic files when an
   arch-specific file is selected.
 - darwin_filter_builtin_sources that implements the EXCLUDE/INCLUDE
   lists (using the files in lib/builtins/Darwin-excludes).

darwin_filter_builtin_sources delegates to filter_builtin_sources.

Previously, lib/builtins/CMakeLists.txt had a number of calls to
filter_builtin_sources (with a confusing/broken use of the
`excluded_list` parameter), as well as a redundant arch-vs-generic
filtering for the non-Apple code path at the end of the file. Replace
all of this with a single call to filter_builtin_sources.

Remove i686_SOURCES. Previously, this list contained only the
arch-specific files common to 32-bit and 64-bit x86, which is a strange
set. Normally the ${ARCH}_SOURCES list contains everything needed for
the arch. "i686" isn't in ALL_BUILTIN_SUPPORTED_ARCH.

NFCI, but i686_SOURCES won't be defined, and the order of files in
${arch}_SOURCES lists will change.

Subject: [PATCH 180/771] [compiler-rt][Android] Stop using detect_target_arch

For Android only, compiler-rt used detect_target_arch to select the
architecture to target. detect_target_arch was added in Sept 2014
(SVN r218605). At that time, compiler-rt selected the default arch
using ${LLVM_NATIVE_ARCH}, which seems to have been the host
architecture and therefore not suitable for cross-compilation.

The compiler-rt build system was refactored in Sept 2015 (SVN r247094
and SVN r247099) to use COMPILER_RT_DEFAULT_TARGET_TRIPLE to control
the target arch rather than LLVM_NATIVE_ARCH. This approach is simpler
and also works for Android cross-compilation, so remove the
detect_target_arch function.

Android targets i686, but compiler-rt seems to identify 32-bit x86 as
"i386". For Android, we were previously calling add_default_target_arch
with i386, and calling add_default_target_arch with i686 does not build
anything. i686 is not listed in builtin-config-ix.cmake,
ALL_BUILTIN_SUPPORTED_ARCH.

Subject: [PATCH 181/771] [builtins][ARM] Replace call_apsr.S with inline asm

The %arm_call_apsr expansion doesn't work when config.clang is a clang
driver defaulting to a non-ARM arch. Rather than fix it, replace
call_apsr.S with inline asm in call_apsr.h, which also resolves the
FIXME added in D31259.

Maybe the `__attribute__((noinline,pcs("aapcs")))` attributes are
unnecessary on the static functions, but I was unsure what liberty the
compiler had to insert instructions that modified the condition codes,
so it seemed helpful.

Subject: [PATCH 182/771] [PowerPC] Fix combineVectorShuffle regression after
 D77448

Commit 1fed131660b2 assumed that NewShuffle (shuffle vector
canonicalization result) will always be ShuffleVectorSDNode, which may
be false (it may be a BITCAST node):

```
...
t12: v4i32 = scalar_to_vector t2
t15: v16i8 = bitcast t12  # LHS
t17: v16i8 = vector_shuffle<u,u,u,u,u,u,u,u,0,1,2,3,u,u,u,u> t15, undef:v16i8  # SVN
```

Subject: [PATCH 183/771] Basic support for flexible array members in constant
 evaluation.

We don't allow runtime-sized flexible array members, nor initialization
of flexible array members, but it seems reasonable to support the most
basic case where the flexible array member is empty.

Subject: [PATCH 190/771] Fix undefined behavior in DWARF emission

Caused by uninitialized load of llvm::DwarfDebug::PrevCU:
llvm::DwarfCompileUnit::addRange () at ../lib/CodeGen/AsmPrinter/DwarfCompileUnit.cpp:276
llvm::DwarfDebug::endFunctionImpl () at ../lib/CodeGen/AsmPrinter/DwarfDebug.cpp:1586
llvm::DebugHandlerBase::endFunction () at ../lib/CodeGen/AsmPrinter/DebugHandlerBase.cpp:319
llvm::AsmPrinter::EmitFunctionBody () at ../lib/CodeGen/AsmPrinter/AsmPrinter.cpp:1230
llvm::ARMAsmPrinter::runOnMachineFunction () at ../lib/Target/ARM/ARMAsmPrinter.cpp:161

Most of the DebugInfo tests under `LLVM_LIT_ARGS:STRING=-sv --vg` prior to this fix, and pass with the fix applied.

Subject: [PATCH 192/771] [VNCoercion] avoid creating bitcast for zero offsets
 [NFCI]

This could previously make it more complicated for ConstantFolding
later, leading to a higher likelyhood it would have to reject the
expression, even though zero seems like probably the common case here.

Subject: [PATCH 193/771] [GVN] teach ConstantFolding correct handling of
 non-integral addrspace casts

Here we teach the ConstantFolding analysis pass that it is not legal to
replace a load of a bitcast constant (having a non-integral addrspace)
with a bitcast of the value of that constant (with a different
non-integral addrspace).

But also teach it that certain bit patterns are always known and
convertable (a fact it already uses elsewhere). This required us to also
fix a globalopt test, since, after this change, LLVM is able to realize
that the test actually is a valid transform (NULL is always a known
bit-pattern) and so it doesn't need to emit the failure remarks for it.

Also simplify some of the negative tests for transforms by avoiding a
type change in their bitcast, and add positive versions of the same
tests, to show that they otherwise should work.

Subject: [PATCH 197/771] [DWARFYAML] Replace Is64bit with Is64BitAddrSize.
 NFC.

Is64bit is ambiguous. In this patch, we replace it with Is64BitAddrSize
to make it clearer.

Subject: [PATCH 203/771] [SVE][CodeGen] Fix implicit TypeSize->uint64_t
 conversion in TransformFPLoadStorePair

In DAGCombiner::TransformFPLoadStorePair we were dropping the scalable
property of TypeSize when trying to create an integer type of equivalent
size. In fact, this optimisation makes no sense for scalable types
since we don't know the size at compile time. I have changed the code
to bail out when encountering scalable type sizes.

I've added a test to

  llvm/test/CodeGen/AArch64/sve-fp.ll

that exercises this code path. The test already emits an error if it
encounters warnings due to implicit TypeSize->uint64_t conversions.

Subject: [PATCH 204/771] [SVE] Fix implicit TypeSize->uint64_t conversion
 getCastInstrCost

In getCastInstrCost() when comparing different sizes for src and
dst types we should be using the TypeSize comparison operators
instead of relying upon TypeSize being converted a uin64_t.
Previously this meant we were dropping the scalable property and
treating fixed and scalable vector types the same.

Subject: [PATCH 205/771] [clangd] Implement textDocument/foldingRange

Summary:
This patch introduces basic textDocument/foldingRange support. It relies on
textDocument/documentSymbols to collect all symbols and uses takes ranges
to create folds.

The next steps for textDocument/foldingRange support would be:

* Implementing FoldingRangeClientCapabilities and respecting respect client
  preferences
* Specifying folding range kind
* Migrating from DocumentSymbol implementation to custom RecursiveASTVisitor flow that will allow more flexibility
* Supporting more folding range types: comments, PP conditional regions, includes and other code regions (e.g. public/private/protected sections of classes, control flow statement bodies)

Tested: (Neo)Vim (coc-clangd) and VSCode.

Subject: [PATCH 206/771] [SVE][CodeGen] Add README for SVE-related warnings in
 tests

I have added a new file:

  llvm/test/CodeGen/AArch64/README

that describes what to do in the event one of the SVE codegen tests
fails the warnings check. In addition, I've added comments to all
the relevant SVE tests pointing users at the README file.

Differential Revision: https://reviews.llvm.org/D83467

+++ SVE CodeGen Warnings ++
+
+When the WARN check lines fail in the SVE codegen tests it most likely means you
+have introduced a warning due to:
+1. Adding an invalid call to VectorType::getNumElements() or EVT::getVectorNumElements()
+   when the type is a scalable vector.
+2. Relying upon an implicit cast conversion from TypeSize to uint64_t.
+
+For generic code, please modify your code to work with ElementCount and TypeSize directly.
+For target-specific code that only deals with fixed-width vectors, use the fixed-size interfaces.
+Please refer to the code where those functions live for more details.

Subject: [PATCH 207/771] [NFCI][InstCombine] Move store merging from
 `visitStoreInst()` into `visitUnconditionalBranchInst()`

Summary:
As @nikic is pointing out in https://bugs.llvm.org/show_bug.cgi?id=46680#c5,
InstCombine should not have forward instruction scans,
so let's move this transform into the proper place.

This is pretty much NFCI.

Subject: [PATCH 208/771] Double check that passes correctly set their Modified
 status

The approach is simple: if a pass reports that it's not modifying a
Function/Module, compute a loose hash of that Function/Module and compare it
with the original one. If we report no change but there's a hash change, then we
have an error.

This approach misses a lot of change but it's not super intrusive and can
detect most of the simple mistakes.

Subject: [PATCH 215/771] [ARM][MVE] Only tail-fold integer add reductions

If a vector body has live-out values, it is probably a reduction, which needs a
final reduction step after the loop. MVE has a VADDV instruction to reduce
integer vectors, but doesn't have an equivalent one for float vectors. A
live-out value that is not recognised as reduction later in the optimisation
pipeline will result in the tail-predicated loop to be reverted to a
non-predicated loop and this is very expensive, i.e. it has a significant
performance impact, which is what we hope to avoid with fine tuning the ARM TTI
hook preferPredicateOverEpilogue implementation.

Subject: [PATCH 220/771] [llvm][unittests] Fix
 ProgramEnvTest.TestExecuteAndWaitStatistics on Solaris

The new `LLVM-Unit :: Support/./SupportTests/ProgramEnvTest.TestExecuteAndWaitStatistics` test currently FAILs on Solaris:

  [ RUN      ] ProgramEnvTest.TestExecuteAndWaitStatistics
  /vol/llvm/src/llvm-project/local/llvm/unittests/Support/ProgramTest.cpp:360: Failure
  Expected: (ProcStat->PeakMemory) > (0U), actual: 0 vs 0
  [  FAILED  ] ProgramEnvTest.TestExecuteAndWaitStatistics (22 ms)

According to `llvm/lib/Support/Unix/Program.inc (llvm::sys::Wait)`, `PeakMemory`
corresponds to `struct rusage.ru_maxrss`.

However, Solaris `getrusage(3C)` documents

  NOTES
         The ru_maxrss, ru_ixrss, ru_idrss, and ru_isrss members of  the  rusage
         structure are set to 0 in this implementation.

Since changing the test to check for `PeakMemory >= 0` instead is pointless
and would generate a warning on targets where `ru_maxrss` is unsigned, this
patch removes the check.

Tested on `amd64-pc-solaris2.11`.

Subject: [PATCH 222/771] [ELF] Do not leave undefined symbols (specified by
 -init and -fini) if they are defined in non-fetched archive members

After D69985, symbols for "-init" and "-fini" were unconditionally
marked as used even if they were just lazy symbols seen when scanning
archives. That resulted in exposing them in the symbol table of an
output file, as Undefined, which added unwanted dependencies. The patch
fixes the issue by checking the kind of the symbols before the marking.

Subject: [PATCH 224/771] [DebugInfo] Fix a possible crash when reading a
 malformed .debug_*lists section.

DWARFListTableHeader::length() handles the zero value of HeaderData.Length
in a special way, which makes the result different from the calculated
value of FullLength, which leads to triggering an assertion. The patch
moves the assertion a bit later when `FullLength` is already checked for
minimal allowed value.

Subject: [PATCH 226/771] [AArch64][AsmParser] Add rcpc support in
 .arch_extension

AArch64 does not support enabling rcpc via .arch_extension in assembly.
GCC, on the other hand, does.

This patch adds 'rcpc' as a valid value to .arch_extension handling.

Subject: [PATCH 231/771] [yaml2obj] - Add a syntax to override e_phoff,
 e_phentsize and e_phnum fields.

This adds `EPhOff`, `EPhEntSize` and `EPhNum` keys.
Will be useful for creating broken objects for testing llvm-readelf.

I managed to trace this to a change in `<sys/regset.h>`: previously the header would
primarily define the short register indices (like `UESP`). While they are required by the
i386 psABI, they are only required in `<ucontext.h>` and could previously leak into
unsuspecting user code, polluting the namespace and requiring elaborate workarounds
like that in `llvm/include/llvm/Support/Solaris/sys/regset.h`. The change fixed that by restricting
the definition of the short forms appropriately, at the same time defining all `REG_` prefixed
forms for compatiblity with other systems.  This exposed a bug in `compiler-rt/lib/sanitizer_common/sanitizer_linux.cpp`, however:
Previously, the index for the user stack pointer would be hardcoded if `REG_ESP`
wasn't defined. Now with that definition present, it turned out that `REG_ESP` was the wrong index to use: the previous value 17 (and `REG_SP`) corresponds to `REG_UESP`
instead.

With that change, the failures are all gone.

Tested on `amd-pc-solaris2.11`.

Subject: [PATCH 234/771] [lldb/test] Avoid globbing in log file handling code

The glob expression for a test called "test" could match a log file for
a the test "test_foo". Instead of globbing, maintain an explicit list of
log files relevant to the current test.

Subject: [PATCH 235/771] [SelectionDAG] Prevent warnings when extracting fixed
 length vector from scalable.

ComputeNumSignBits and computeKnownBits both trigger "Scalable flag
may be dropped" warnings when a fixed length vector is extracted
from a scalable vector.  This patch assumes nothing about the
demanded elements thus matching the behaviour when extracting a
scalable vector from a scalable vector.

Subject: [PATCH 237/771] [test/Object][llvm-objdump] - llvm-objdump: don't
 abort() when the e_phoff field is invalid and refine testing.

llvm-objdump currently calls report_fatal_error() when the e_phoff field is invalid.

This is tested by elf-invalid-phdr.test which has the following issues:
1) It uses a precompiled object.
2) it could be a part of invalid.test.
3) It tests the Object lib, but we have no separate test for llvm-objdump.

This patch addresses issues mentioned.

Subject: [PATCH 239/771] [ValueTracking] fix miscompile in maxnum case of
 cannotBeOrderedLessThanZeroImpl (PR46627)

A miscompile with -0.0 is shown in:
http://bugs.llvm.org/PR46627

This is because maxnum(-0.0, +0.0) does not specify a fixed result:
http://llvm.org/docs/LangRef.html#llvm-maxnum-intrinsic

So we need to tighten the constraints for when it is ok to say the
result of maxnum is positive (including +0.0).

Subject: [PATCH 240/771] [yaml2obj] - Refine handling of the NoHeaders key.

Imagine we have an YAML description for some object and we want to
produce 2 outputs: with and without the section header.
A natural way to do it would look like:

```
--- !ELF
FileHeader:
  Class:   ELFCLASS64
  Data:    ELFDATA2LSB
  Type:    ET_REL
  Machine: EM_X86_64
Sections:
...
SectionHeaderTable:
  NoHeaders: [[NOHEADERS]]

```
But currently, we do not distinguish between no `NoHeaders` key case
and `NoHeaders == false`. Because of this we can't simply specify
`NOHEADERS = false`, as tool starts to complain.

With this patch the behavior changed. When we have:

```
SectionHeaderTable:
  NoHeaders: false

```
it is the same as we have no `SectionHeaderTable` at all.
(`NoHeaders` key still can't be used with `Sections/Excluded` keys)

Subject: [PATCH 242/771] Revert "[SCEV][IndVarSimplify] insert point should
 not be block front."

This reverts commit f1efb8bb4ba0584a9b994f3404a2c62920ce6652.

Reverted because it doesn't correctly update the pass return status, see

Subject: [PATCH 243/771] [flang][OpenMP] upstream OpenMP lowering

Summary:
This patch implements lowering of OpenMP barrier construct from
pft to OpenMPDialect.

Patch is carved out of following merged PR's from fir-dev branch
of https://github.com/flang-compiler/f18-llvm-project/

PR's:
https://github.com/flang-compiler/f18-llvm-project/pull/248
https://github.com/flang-compiler/f18-llvm-project/pull/251

Unfortunately primary tool `bbc` for functional validation is not
yet upstreamed. So this patch includes a unittest for lowering
`!OMP barrier` construct.

Some part of the these PR's still remains downstream(functional test
and dialect registration to legalizer) for obvious reasons.
Will upstream them when the dependencies are upstreamed.

Subject: [PATCH 245/771] [RISCV] Fix isStoreToStackSlot

Because of the layout of stores (that don't have a destination operand)
this check is exactly the same as the one in
RISCVInstrInfo::isLoadFromStackSlot.

Subject: [PATCH 246/771] Prohibit use of _ExtInt in atomic intrinsic

The _ExtInt type allows custom width integers, but the atomic memory
access's operand must have a power-of-two size. _ExtInts with
non-power-of-two size should not be allowed for atomic intrinsic.

Before this change:

$ cat test.c

typedef unsigned _ExtInt(42) dtype;
void verify_binary_op_nand(dtype* pval1, dtype val2)
{    __sync_nand_and_fetch(pval1, val2); }

$ clang test.c

clang-11:
/home/ubuntu/llvm_workspace/llvm/clang/lib/CodeGen/CGBuiltin.cpp:117:
llvm::Value*
EmitToInt(clang::CodeGen::CodeGenFunction&, llvm::Value*,
clang::QualType, llvm::IntegerType*): Assertion `V->getType() ==
IntType' failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the
crash backtrace, preprocessed source, and associated run script.

After this change:

$ clang test.c

test.c:3:30: error: Atomic memory operand must have a power-of-two size
{    __sync_nand_and_fetch(pval1, val2); }
^

List of the atomic intrinsics that have this
problem:

__sync_fetch_and_add
__sync_fetch_and_sub
__sync_fetch_and_or
__sync_fetch_and_and
__sync_fetch_and_xor
__sync_fetch_and_nand
__sync_nand_and_fetch
__sync_and_and_fetch
__sync_add_and_fetch
__sync_sub_and_fetch
__sync_or_and_fetch
__sync_xor_and_fetch
__sync_fetch_and_min
__sync_fetch_and_max
__sync_fetch_and_umin
__sync_fetch_and_umax
__sync_val_compare_and_swap
__sync_bool_compare_and_swap

Subject: [PATCH 248/771] [clangd] Add library to semantically strip flags by
 name.

Summary:
This is designed for tweaking compile commands by specifying flags to add/remove
in a config file. Something like:
  CompileFlags: { Remove: -fcolor-diagnostics }

Having users tweak raw argv (e.g. with a regex) is going to end in tears: bugs
around clang-cl, xclang, aliases, joined-vs-separate args etc are inevitable.

This isn't in tooling because of the performance choices: build a big table
up-front to make subsequent actions fast. Maybe it should be though.

Subject: [PATCH 249/771] Fix test for the hasExternalFormalLinkage matcher

Summary:
Names of local variables have no linkage (see C++20 [basic.link] p8).

Names of variables in unnamed namespace have internal linkage (see C++20
[basic.link] p4).

Subject: [PATCH 250/771] [ods] Enable getting forward decls allow

Summary: Currently forward decls are included with all the op classes. But there are cases (say when splitting up headers) where one wants the forward decls but not all the classes. Add an option to enable this. This does not change any current behavior (some further refactoring is probably due here).

Subject: [PATCH 251/771] [libc++] Use a proper CMake target to represent
 libc++ headers

Instead of having complex logic around how to include the libc++ headers
and __config_site, handle that by defining cxx-headers as an INTERFACE
library and linking against it. After this patch, linking against cxx-headers
is sufficient to get the right __config_site include and include paths
for libc++.

Subject: [PATCH 252/771] [utils] New script `check_ninja_deps.py`

Summary:
This can be run after a ninja-based build, and analyzes the ninja
build files and dependency database to spot any missing dependencies
in the build scripts.

I wrote it in the course of investigating D82659, and it seems likely
to be useful again.

+"""Script to find missing formal dependencies in a build.ninja file.
+
+Suppose you have a header file that's autogenerated by (for example) Tablegen.
+If a C++ compilation step needs to include that header, then it must be
+executed after the Tablegen build step that generates the header. So the
+dependency graph in build.ninja should have the Tablegen build step as an
+ancestor of the C++ one. If it does not, then there's a latent build-failure
+bug, because depending on the order that ninja chooses to schedule its build
+steps, the C++ build step could run first, and fail because the header it needs
+does not exist yet.
+
+But because that kind of bug can easily be latent or intermittent, you might
+not notice, if your local test build happens to succeed. What you'd like is a
+way to detect problems of this kind reliably, even if they _didn't_ cause a
+failure on your first test.
+
+This script tries to do that. It's specific to the 'ninja' build tool, because
+ninja has useful auxiliary output modes that produce the necessary data:
+
+ - 'ninja -t graph' emits the full DAG of formal dependencies derived from
+   build.ninja (in Graphviz format)
+
+ - 'ninja -t deps' dumps the database of dependencies discovered at build time
+   by finding out which headers each source file actually included
+
+By cross-checking these two sources of data against each other, you can find
+true dependencies shown by 'deps' that are not reflected as formal dependencies
+in 'graph', i.e. a generated header that is required by a given source file but
+not forced to be built first.
+
+To run it:
+
+ - set up a build directory using ninja as the build tool (cmake -G Ninja)
+
+ - in that build directory, run ninja to perform an actual build (populating
+   the dependency database)
+
+ - then, in the same build directory, run this script. No arguments are needed
+   (but -C and -f are accepted, and propagated to ninja for convenience).
+
+Requirements outside core Python: the 'pygraphviz' module, available via pip or
+as the 'python3-pygraphviz' package in Debian and Ubuntu.

Subject: [PATCH 256/771] [clangd] Cache config files for 5 seconds, without
 revalidating with stat.

Summary:
This is motivated by:
 - code completion: nice to do no i/o on the request path
 - background index: deciding whether to enqueue each file would stat the config
   file thousands of times in quick succession.

Currently it's applied uniformly to all requests though.

This gives up on performing stat() outside the lock, all this achieves is
letting multiple threads stat concurrently (and thus finish without contention
for nonexistent files).
The ability to finish without IO (just mutex lock + integer check) should
outweigh this, and is less sensitive to platform IO characteristics.

Subject: [PATCH 258/771] [lldb] Make `process connect` blocking in synchronous
 mode.

In synchronous mode, the process connect command and its aliases should
wait for the stop event before claiming the command is complete.
Currently, the stop event is always handled asynchronously by the
debugger.

The implementation takes the same approach as Process::ResumeSynchronous
which hijacks the event and handles it on the current thread. Similarly,
after this patch, the stop event is part of the command return object,
which is the property used by the test case.

Subject: [PATCH 259/771] [lldb/Module] Allow for the creation of memory-only
 modules

Summary:
This patch extends the ModuleSpec class to include a
DataBufferSP which contains the module data. If this
data is provided, LLDB won't try to hit the filesystem
to create the Module, but use only the data stored in
the ModuleSpec.

Reviewers: labath, espindola

Subject: [PATCH 262/771] [docs] Update llvm.loop metadata documentation.

Loop metadata nodes do not adhere to the documented property:

(a) LoopIDs are not unique: Any pass that duplicates IR will do it
    including its metadata (e.g. LoopVersioning) such that multiple
    loops are linked with the same LoopID. There is even a test case
    (Transforms/LoopUnroll/unroll-pragmas-disabled.ll) for multiple
    loops with the same LoopID.

(b) LoopIDs are not persistent: Adding or removing an item from a LoopID
    can only be done by creating a new MDNode and assigning it to the
    loop's branch(es). Passes such as LoopUnroll (llvm.loop.unroll.disable)
    and LoopVectorize (llvm.loop.isvectorized) use this to mark loops to
    not be transformed multiple times or to avoid that a LoopVersioned
    original loop is transformed.

Update the documentation according to how llvm.loop is used in practice.

 It is sometimes useful to attach information to loop constructs. Currently,
 loop metadata is implemented as metadata attached to the branch instruction
-in the loop latch block. This type of metadata refer to a metadata node that is
-guaranteed to be separate for each loop. The loop identifier metadata is
-specified with the name ``llvm.loop``.
-
-The loop identifier metadata is implemented using a metadata that refers to
-itself to avoid merging it with any other identifier metadata, e.g.,
-during module linkage or function inlining. That is, each loop should refer
-to their own identification metadata even if they reside in separate functions.
-The following example contains loop identifier metadata for two separate loop
-constructs:
-
-.. code-block:: llvm
-
-    !0 = !{!0}
-    !1 = !{!1}
-
-The loop identifier metadata can be used to specify additional
-per-loop metadata. Any operands after the first operand can be treated
-as user-defined metadata. For example the ``llvm.loop.unroll.count``
-suggests an unroll factor to the loop unroller:
+in the loop latch block. The loop metadata node is a list of
+other metadata nodes, each representing a property of the loop. Usually,
+the first item of the property node is a string. For example, the
+``llvm.loop.unroll.count`` suggests an unroll factor to the loop
+unroller:
 
 .. code-block:: llvm
 
       br i1 %exitcond, label %._crit_edge, label %.lr.ph, !llvm.loop !0
     ...
-    !0 = !{!0, !1}
-    !1 = !{!"llvm.loop.unroll.count", i32 4}
+    !0 = !{!0, !1, !2}
+    !1 = !{!"llvm.loop.unroll.enable"}
+    !2 = !{!"llvm.loop.unroll.count", i32 4}
+
+For legacy reasons, the first item of a loop metadata node must be a
+reference to itself. Before the advent of the 'distinct' keyword, this
+forced the preservation of otherwise identical metadata nodes. Since
+the loop-metadata node can be attached to multiple nodes, the 'distinct'
+keyword has become unnecessary.
+
+Prior to the property nodes, one or two ``DILocation`` (debug location)
+nodes can be present in the list. The first, if present, identifies the
+source-code location where the loop begins. The second, if present,
+identifies the source-code location where the loop ends.
+
+Loop metadata nodes cannot be used as unique identifiers. They are
+neither persistent for the same loop through transformations nor
+necessarily unique to just one loop.

Subject: [PATCH 264/771] [AIX] Remove diff -a option on llvm-cov.test

Summary:
llvm-cov.test generates .gcov files and compared with target
sample files. Since the files do not contain any binary data
(files are plain ASCII texts), remove -a from diff. And this
fix will the error on AIX since the default diff tool on AIX
does not support -a option.

Subject: [PATCH 266/771] [clang] Add 'override' to virtual function overrides
 generated by ClangAttrEmitter

ClangAttrEmitter.cpp generates ParsedAttr derived classes with virtual overrides in them (which end up in AttrParsedAttrImpl.inc); this patch ensures these generated functions are marked override, and not (redundantly) virtual.

I hesitate to say NFC since this does of course affect the behavior of the generator code, but the generated code behaves the same as it did before, so it's NFC in that sense.

Subject: [PATCH 267/771] [NFC] Add 'override' keyword where missing in
 include/ and lib/.

This fixes warnings raised by Clang's new -Wsuggest-override, in preparation for enabling that warning in the LLVM build. This patch also removes the virtual keyword where redundant, but only in places where doing so improves consistency within a given file. It also removes a couple unnecessary virtual destructor declarations in derived classes where the destructor inherited from the base class is already virtual.

Subject: [PATCH 268/771] Fix merging of two arity-only pack deductions.

If we deduced the arity of a pack in two different ways, but didn't
deduce an element of the pack in either of those deductions, we'd merge
that element to produce a null template argument, which we'd incorrectly
interpret as the merge having failed.

Testcase based on one supplied by Hubert Tong.

Subject: [PATCH 269/771] [clangd] Config: Index.Background

Summary:
We only support Build/Skip for now, but with 'Load' or similar as an
option for future (load existing shards but don't build new ones).

This requires creating the config for each TU on startup. In LLVM, this
is 4000 occurrences for a total of 800ms on my machine.
But together with caching from D83755 it is only 25ms.

Subject: [PATCH 280/771] TableGen/GlobalISel: Partially fix nontrivial, custom
 predicates

Currently custom code predicates can only really be used for
contextless checks tied to a single instruction (e.g. check the def
for hasOneUse). If you do want to inspect the input instructions in
the source pattern, you cannot without re-verifying the opcode and
type checks implied by the patterns, since this check was emitted
before any operand constraints. Really, these are pattern level
predicates that implicitly depend on the instruction and operand
checks.

Introduce a filtering function so the custom predicate is emitted
last. I'm not sure this is the most elegant solution. It seems like
this is really a different thing from the InstructionMatcher/IPM_
predicate kinds. I initially tried keeping this in a separate
predicate list, but that also seemed awkward.

This only half fixes the problem I'm trying to solve. The AMDGPU
pattern I'm attempting to port also uses the PredicateCodeUsesOperands
feature to allow checks on the source operands when the input pattern
is commuted. Really the emitter should reject the pattern since it
doesn't handle this case, but at this point it would be more
productive to just implement this.

Subject: [PATCH 285/771] [Matrix] Intrinsic descriptions

This changes the matrix load/store intrinsic definitions to load/store from/to
a pointer, and not from/to a pointer to a vector, as discussed in D83477.

This also includes the recommit of "[Matrix] Tighten LangRef definitions and
Verifier checks" which adds improved language reference descriptions of the
matrix intrinsics and verifier checks.

Subject: [PATCH 286/771] [flang] Change the default F18_FC to gfortran

Summary: Changed default F18_FC from pgf90 to gfortran. Removed unnecessary references to pgf90 in favor of more generic naming.

Subject: [PATCH 287/771] Restore "[WPD/LowerTypeTests] Delay lowering/removal
 of type tests until after ICP"

This restores commit 80d0a137a5aba6998fadb764f1e11cb901aae233, and the
follow on fix in 873c0d0786dcf22f4af39f65df824917f70f2170, with a new
fix for test failures after a 2-stage clang bootstrap, and a more robust
fix for the Chromium build failure that an earlier version partially
fixed. See also discussion on D75201.

Subject: [PATCH 288/771] llvm-link: Add support for archive files as inputs

This patch adds support for archive files as inputs to llvm-link. One
of the use-cases is for OpenMP, where device specific libraries need
to be extracted from libraries containing bundled object files. The
clang-offload-bundler will support extracting these archives, which
will be passed into llvm-link, see https://reviews.llvm.org/D80816.

Subject: [PATCH 291/771] [NFC] Add debug and stat counters to assume queries
 and assume builder

Summary:
Add debug counter and stats counter to assume queries and assume builder
here is the collected stats on a build of check-llvm + check-clang.
  "assume-builder.NumAssumeBuilt": 2720879,
  "assume-builder.NumAssumesMerged": 761396,
  "assume-builder.NumAssumesRemoved": 1576212,
  "assume-builder.NumBundlesInAssumes": 6518809,
  "assume-queries.NumAssumeQueries": 85566380,
  "assume-queries.NumUsefullAssumeQueries": 2727360,
the NumUsefullAssumeQueries stat is actually pessimistic because in a few places queries
ask to keep providing information to try to get better information. and this isn't counted
as a usefull query evem tho it can be usefull

Subject: [PATCH 292/771] Call Frame Information (CFI) Handling for Basic Block
 Sections
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch handles CFI with basic block sections, which unlike DebugInfo does
not support ranges. The DWARF standard explicitly requires emitting separate
CFI Frame Descriptor Entries for each contiguous fragment of a function. Thus,
the CFI information for all callee-saved registers (possibly including the
frame pointer, if necessary) have to be emitted along with redefining the
Call Frame Address (CFA), viz. where the current frame starts.

CFI directives are emitted in FDE’s in the object file with a low_pc, high_pc
specification. So, a single FDE must point to a contiguous code region unlike
debug info which has the support for ranges. This is what complicates CFI for
basic block sections.

Now, what happens when we start placing individual basic blocks in unique
sections:

* Basic block sections allow the linker to randomly reorder basic blocks in the
address space such that a given basic block can become non-contiguous with the
original function.
* The different basic block sections can no longer share the cfi_startproc and
cfi_endproc directives. So, each basic block section should emit this
independently.
* Each (cfi_startproc, cfi_endproc) directive will result in a new FDE that
caters to that basic block section.
* Now, this basic block section needs to duplicate the information from the
entry block to compute the CFA as it is an independent entity. It cannot refer
to the FDE of the original function and hence must duplicate all the stuff that
is needed to compute the CFA on its own.
* We are working on a de-duplication patch that can share common information in
FDEs in a CIE (Common Information Entry) and we will present this as a follow up
patch. This can significantly reduce the duplication overhead and is
particularly useful when several basic block sections are created.
* The CFI directives are emitted similarly for registers that are pushed onto
the stack, like callee saved registers in the prologue. There are cfi
directives that emit how to retrieve the value of the register at that point
when the push happened. This has to be duplicated too in a basic block that is
floated as a separate section.

Subject: [PATCH 293/771] [mlir][DialectConversion] Emit an error if an
 operation marked as erased has live users after conversion

Up until now, there has been an implicit agreement that when an operation is marked as
"erased" all uses of that operation's results are guaranteed to be removed during conversion. How this works in practice is that there is either an assert/crash/asan failure/etc. This revision adds support for properly detecting when an erased operation has dangling users, emits and error and fails the conversion.

Differential Revision: https://reviews.llvm.org/D82830

Subject: [PATCH 294/771] [CallGraph] Ignore callback uses

Summary:
Ignore callback uses when adding a callback function
in the CallGraph. Callback functions are typically
created when outlining, e.g. for OpenMP, so they have
internal scope and linkage. They should not be added
to the ExternalCallingNode since they are only callable
by the specified caller function at creation time.

A CGSCC pass, such as OpenMPOpt, may need to update
the CallGraph by adding a new outlined callback function.
Without ignoring callback uses, adding breaks CGSCC
pass restrictions and results to a broken CallGraph.

Subject: [PATCH 295/771] [mlir] Add support for parsing optional Attribute
 values.

This adds a `parseOptionalAttribute` method to the OpAsmParser that allows for parsing optional attributes, in a similar fashion to how optional types are parsed. This also enables the use of attribute values as the first element of an assembly format optional group.

Subject: [PATCH 296/771] [flang] Tuning up binary->decimal conversion

Use short division of big-radix values by powers of two when
converting values with negative unbiased exponents rather than
multiplication by smaller powers of five; this reduces the overall
outer iteration count. This change is a win across the entire range
of inputs.

Subject: [PATCH 298/771] [libc++] Automatically detect whether RTTI is enabled

Instead of detecting it automatically but also allowing for the setting
to be specified explicitly, always detect whether exceptions are enabled
based on whether -fno-rtti (or equivalent) is used. It's less confusing
to have a single way of tweaking that knob.

This change follows the lead of 71d88cebfb42.

Subject: [PATCH 300/771] [lldb/Test] Always set the cleanupSubprocesses tear
 down hook

Always clean up subprocesses on tear down instead of relying on the
caller to do so. This is not only less error prone but also means the
tests can be more concise.

Subject: [PATCH 302/771] [llvm][NFC] expose LLVM_HAVE_TF_API through
 llvm-config.h

Summary:
This allows users of the llvm library discover whether llvm was built
with the tensorflow c API dependency, which helps if using the TFUtils
wrapper, for example.

We don't do the same for the LLVM_HAVE_TF_AOT flag, because that does
not expose any API.

We need to retain carriage return characters in source files
that are not parts of multi-byte line endings; they are
significant in CHARACTER literal constants.

+- -fpch-instantiate-templates tries to instantiate templates already while
+  generating a precompiled header. Such templates do not need to be
+  instantiated every time the precompiled header is used, which saves compile
+  time. This may result in an error during the precompiled header generation

Subject: [PATCH 305/771] [clang-tidy] OptionsView::store specialized on bool

Following on fcf7cc268fe and 672207c319a which granted checks the ability to read boolean configuration arguments as `true` or `false`.
This enables storing the options back to the configuration file using `true` and `false`.
This is in line with how clang-format dumps boolean options in its style config.

Subject: [PATCH 307/771] [libFuzzer] Separate platform related macros out from
 FuzzerDefs.h into FuzzerPlatform.h, and adjust includes in other files.

Summary: This patch separates platform related macros in lib/fuzzer/FuzzerDefs.h into lib/fuzzer/FuzzerPlatform.h, and use FuzzerPlatform.h where necessary. This separation helps when compiling libFuzzer's interceptor module (under review); an unnecessary include of standard headers (such as string.h) may produce conflicts/ambiguation with the interceptor's declarations/definitions of library functions, which complicates interceptor implementation.

 W_value Group

Summary:
-fembed-bitcode options doesn't embed warning options since they are
useless to code generation. Make sure it handles the W_value group and
not embed those options in the output.

Subject: [PATCH 310/771] [flang] Fix a crash when an array constructor
 contains an unlimited polymorphic value

Summary:
C7113 States that "An ac-value shall not be unlimited polymorphic."  We failed
to detect this situation which resulted in a crash when trying to get the
underlying derived type specification of the unlimited polymorphic value.

I added code to avoid the crash, code to emit an error message, and a test.

Subject: [PATCH 323/771] [IR] Add a few asserts to provide a better failure
 signature if you try to create a load/store/alloca with no alignment or
 insertion position

If no alignment is specified we try to find the datalayout by using the insert position to get the module so we can get the datalayout. But if those are null, then we deference a null pointer.

This patch adds asserts to make the failure a little more obvious than just seg faulting.

Subject: [PATCH 329/771] [Attributor] [WIP] Track AA dependency using
 dependency graph

Summary: This patch added dependency graph to the attributor so that we can dump the dependencies between AAs more easily. We can also apply general graph algorithms to the graph, making it easier for us to create deep wrappers.

Subject: [PATCH 330/771] [CMake] Simplify CMake handling for zlib

Rather than handling zlib handling manually, use find_package from CMake
to find zlib properly. Use this to normalize the LLVM_ENABLE_ZLIB,
HAVE_ZLIB, HAVE_ZLIB_H. Furthermore, require zlib if LLVM_ENABLE_ZLIB is
set to YES, which requires the distributor to explicitly select whether
zlib is enabled or not. This simplifies the CMake handling and usage in
the rest of the tooling.

This is a reland of abb0075 with all followup changes and fixes that
should address issues that were reported in PR44780.

Subject: [PATCH 332/771] [Attributor] Track AA dependency using dependency
 graph

Summary: This patch added dependency graph to the attributor so that we can dump the dependencies between AAs more easily. We can also apply general graph algorithms to the graph, making it easier for us to create deep wrappers.

Subject: [PATCH 333/771] Revert "[CMake] Simplify CMake handling for zlib"

This reverts commit 8c1a79dc12f3cc600e16153961cd8cc50ba2c33b because
it fails when zlib isn't installed.

Subject: [PATCH 334/771] [OpenMP] Emit remarks during GPU state machine
 optimization

Since D83271 we can optimize the GPU state machine to avoid spurious
call edges that increase the register usage of kernels. With this patch
we inform the user why and if this optimization is happening and when it
is not.

Subject: [PATCH 335/771] [CallGraph] Update callback call sites in
 RefreshCallGraph

Since D82572, we keep "reference" edges for callback call sites. While
not strictly necessary they can improve the traversal order. However, we
did not update them properly in case a pass removed the callback call
site which caused a verification error (PR46687). With this patch we
update these reference edges properly during the invocation of
`CallGraphSCCPass::RefreshCallGraph` in non-checking mode.

Subject: [PATCH 336/771] [OpenMP][IRBuilder] Support nested parallel regions

During code generation we might change/add basic blocks so keeping a
list of them is fairly easy to break. Nested parallel regions were
enough. The new scheme does recompute the list of blocks to be outlined
once it is needed.

Subject: [PATCH 340/771] [llvm][NFC] Hide the tensorflow dependency from
 headers.

Summary:
This change avoids exposing tensorflow types when including TFUtils.h.
They are just an implementation detail, and don't need to be used
directly when implementing an analysis requiring ML model evaluation.

The TFUtils APIs, while generically typed, are still not exposed unless
the tensorflow C library is present, as they currently have no use
otherwise.

Subject: [PATCH 343/771] [mlir][Vector] Degrade masking information when
 forwarding linalg.copy to vector.transfer

Summary:
linalg.copy + linalg.fill can be used to create a padded local buffer.
The `masked` attribute is only valid on this padded buffer.
When forwarding to vector.transfer ops, the attribute must be reset
conservatively.

Subject: [PATCH 347/771] [MLIR][SPIRVToLLVM] SPIRV function fix and nits

This patch addresses the comments from https://reviews.llvm.org/D83030 and
https://reviews.llvm.org/D82639. `this->` is removed when not inside the
template. Also, type conversion for `spv.func` takes `convertRegionTypes()`
in order to apply type conversion on all blocks within the function.

Subject: [PATCH 349/771] [DAGCombiner] Rebuild (setcc x, y, ==) from (xor (xor
 x, y), 1)

The existing code already considered this case. Unfortunately a typo in
the condition prevents it from triggering. Also the existing code, had
it run, forgot to do the folding.

This fixes PR42876.

Subject: [PATCH 350/771] [RISCV] Add error checking for extensions missing
 separating underscores

Currently if two multi-letter extensions are provided in a -march=
string, the verification code checks the version of the first and
consumes the second, resulting in that part of the architecture
string being ignored. This adds a test that when a version number has
been parsed for an extension, there are no subsequent characters.

Subject: [PATCH 351/771] [lldb][formatters] Add support for printing
 NSConstantDate and fix distantPast value

Summary:

Certain `NSDate` constructors return a special `NSConstantDate` class which
currently ends up being unformatted as it's not in the list of supported classes
for the NSDate formatter. This patch adds that class to the supported class list
so LLDB produces a summary for it.

One of these special constructors is `[NSDate distantPast]` which returns the
date for `0001-01-01 00:00:00 UTC`. LLDB has a special case for formatting this
date but for some reason we did hardcode the wrong summary string in that
special case. Maybe the summary string was correct back when the code was
written but it isn't correct anymore (`distantPast` isn't actually defined to be
a special date but just some 'a guaranteed temporal boundary.' so maybe someone
changed the value in the last 10 years).

If someone else is wondering why we even have this special case for
`distantPast` but not for the future. The reason seems to be that our date
formatting for really old dates is off by 24 hours. So for example, adding one
second to `distantPast` will cause LLDB to print `0000-12-30 00:00:01 UTC`
(which is 24 hours behind the expected result). So to make our code appear to be
correct it seems we just hardcoded the most common NSDate result from that time
span. I'll replace that logic with a generic solution in a probably more
invasive follow up patch.

I also took the freedom to replace the magic value `-63114076800` with some
constant + documentation. I heard there are some people that don't know from the
top of their head that there are 63114076800 seconds between 1. Jan 0001 and 1.
January 2001 in whatever calendar system NSDate is using.

Subject: [PATCH 352/771] [clang][Driver] Fix tool path priority test failures

Summary:
Failure type 1:
This test can fail when the path of the build includes the strings
we're checking for. E.g "/gcc" is found in ".../gcc_7.3.0/..."

To correct this look for '"' on the end of all matches. So that we
only match the end of paths printed by clang -###.
(which would be ".../gcc_7.3.0/.../gcc" for the example)

Also look for other gcc names like gcc-x.y.z in the first check.
This confirms that the copy of clang we made is isolated as expected.

Failure type 2:
If you use a triple like "powerpc64le-linux-gnu" clang actually reports
"powerpc64le-unknown-linux-gnu". Then it searches for the
former.

That combined with Mac OS adding a version number to cmake's triple
means we can't trust cmake or clang to give us the one default triple.
To fix the test, write to both names. As they don't overlap with our
fake triple, we're still showing that the lookup works.

Subject: [PATCH 353/771] AArch64+ARM: make LLVM consider system registers
 volatile.

Some of the system registers readable on AArch64 and ARM platforms
return different values with each read (for example a timer counter),
these shouldn't be hoisted outside loops or otherwise interfered with,
but the normal @llvm.read_register intrinsic is only considered to read
memory.

This introduces a separate @llvm.read_volatile_register intrinsic and
maps all system-registers on ARM platforms to use it for the
__builtin_arm_rsr calls. Registers declared with asm("r9") or similar
are unaffected.

 out of bounds

Fix incorrect use of the size of Path when accessing PathUTF16, as the
UTF-16 path can be shorter. Added unit test for coverage of this test
case.

Thanks to Ding Fei (danix800) for the code fix, see

Subject: [PATCH 358/771] [Matrix] Only pass vector arg as overloaded type in
 MatrixBuilder.

In 2b3c505, the pointer arguments for the matrix load and store
intrinsics was changed to always be the element type of the vector
argument.

This patch updates the MatrixBuilder to not add the pointer type to the
overloaded types and adjusts the clang/mlir tests.

This should fix a few build failures on GreenDragon, including
 http://green.lab.llvm.org/green/job/test-suite-verify-machineinstrs-x86_64-O0-g/7891/

Subject: [PATCH 359/771] [yaml2obj] - Rename FileHeader::SH* fields.

In D83482 we agreed to name e_* fields that are used for overriding
values (like e_phoff) as EPh* (e.g. EPhOff).

Currently we have a set of e_sh* fields that are named inconsistently
with this rule. This patch renames all of them.

Subject: [PATCH 360/771] [RISCV] Fix RISCVInstrInfo::getInstSizeInBytes for
 atomics pseudos

Summary:
Without these, the generic branch relaxation pass will underestimate the
range required for branches spanning these and we can end up with
"fixup value out of range" errors rather than relaxing the branches.
Some of the instructions in the expansion may end up being compressed
but exactly determining that is awkward, and these conservative values
should be safe, if slightly suboptimal in rare cases.

-New module
-^^^^^^^^^^
-- New module `llvmlibc`.
-
-  This module contains checks related to the LLVM-libc coding standards.
-
-New checks
-^^^^^^^^^^
-
-- New :doc:`abseil-string-find-str-contains
-  <clang-tidy/checks/abseil-string-find-str-contains>` check.
-
-  Finds ``s.find(...) == string::npos`` comparisons (for various string-like types)
-  and suggests replacing with ``absl::StrContains()``.
-
-- New :doc:`cppcoreguidelines-avoid-non-const-global-variables
-  <clang-tidy/checks/cppcoreguidelines-avoid-non-const-global-variables>` check.
-  Finds non-const global variables as described in check I.2 of C++ Core
-  Guidelines.
-
-- New :doc:`bugprone-misplaced-pointer-arithmetic-in-alloc
-  <clang-tidy/checks/bugprone-misplaced-pointer-arithmetic-in-alloc>` check.
-
-  Finds cases where an integer expression is added to or subtracted from the
-  result of a memory allocation function (``malloc()``, ``calloc()``,
-  ``realloc()``, ``alloca()``) instead of its argument.
-
-- New :doc:`bugprone-no-escape
-  <clang-tidy/checks/bugprone-no-escape>` check.
-
-  Finds pointers with the ``noescape`` attribute that are captured by an
-  asynchronously-executed block.
-
-- New :doc:`bugprone-spuriously-wake-up-functions
-  <clang-tidy/checks/bugprone-spuriously-wake-up-functions>` check.
-
-  Finds ``cnd_wait``, ``cnd_timedwait``, ``wait``, ``wait_for``, or
-  ``wait_until`` function calls when the function is not invoked from a loop
-  that checks whether a condition predicate holds or the function has a
-  condition parameter.
-
-- New :doc:`bugprone-reserved-identifier
-  <clang-tidy/checks/bugprone-reserved-identifier>` check.
-
-  Checks for usages of identifiers reserved for use by the implementation.
-
-- New :doc:`bugprone-suspicious-include
-  <clang-tidy/checks/bugprone-suspicious-include>` check.
-
-  Finds cases where an include refers to what appears to be an implementation
-  file, which often leads to hard-to-track-down ODR violations, and diagnoses
-  them.
-
-- New :doc:`cert-oop57-cpp
-  <clang-tidy/checks/cert-oop57-cpp>` check.
-
-  Flags use of the `C` standard library functions ``memset``, ``memcpy`` and
-  ``memcmp`` and similar derivatives on non-trivial types.
-
-- New :doc:`llvmlibc-callee-namespace
-  <clang-tidy/checks/llvmlibc-callee-namespace>` check.
-
-  Checks all calls resolve to functions within ``__llvm_libc`` namespace.
-
-- New :doc:`llvmlibc-implementation-in-namespace

-
-- Checks supporting the ``HeaderFileExtensions`` flag now support ``;`` as a
-  delimiter in addition to ``,``, with the latter being deprecated as of this
-  release. This simplifies how one specifies the options on the command line:
-  ``--config="{CheckOptions: [{ key: HeaderFileExtensions, value: h;;hpp;hxx }]}"``
-
-Renamed checks
-^^^^^^^^^^^^^^
-
-- The 'fuchsia-restrict-system-headers' check was renamed to :doc:`portability-restrict-system-includes

 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-- -Wpointer-to-int-cast is a new warning group. This group warns about C-style
-  casts of pointers to a integer type too small to hold all possible values.

 Non-comprehensive list of changes in this release
 -------------------------------------------------
 
-- For the ARM target, C-language intrinsics are now provided for the full Arm
-  v8.1-M MVE instruction set. ``<arm_mve.h>`` supports the complete API defined
-  in the Arm C Language Extensions.
-
-- For the ARM target, C-language intrinsics ``<arm_cde.h>`` for the CDE
-  instruction set are now provided.
-
-- clang adds support for a set of  extended integer types (``_ExtInt(N)``) that
-  permit non-power of 2 integers, exposing the LLVM integer types. Since a major
-  motivating use case for these types is to limit 'bit' usage, these types don't
-  automatically promote to 'int' when operations are done between two
-  ``ExtInt(N)`` types, instead math occurs at the size of the largest
-  ``ExtInt(N)`` type.
-
-- Users of UBSan, PGO, and coverage on Windows will now need to add clang's
-  library resource directory to their library search path. These features all
-  use runtime libraries, and Clang provides these libraries in its resource
-  directory. For example, if LLVM is installed in ``C:\Program Files\LLVM``,
-  then the profile runtime library will appear at
-  ``C:\Program Files\LLVM\lib\clang\11.0.0\lib\windows\clang_rt.profile-x86_64.lib``.
-  To ensure that the linker can find the appropriate library, users should pass
-  ``/LIBPATH:C:\Program Files\LLVM\lib\clang\11.0.0\lib\windows`` to the
-  linker. If the user links the program with the ``clang`` or ``clang-cl``
-  drivers, the driver will pass this flag for them.
-
-- Clang's profile files generated through ``-fprofile-instr-generate`` are using
-  a fixed hashing algorithm that prevents some collision when loading
-  out-of-date profile informations. Clang can still read old profile files.
+- ...
 
 New Compiler Flags
 ------------------
 
-- -fstack-clash-protection will provide a protection against the stack clash
-  attack for x86, s390x and ppc64 architectures through automatic probing of
-  each page of allocated stack.
-
-- -ffp-exception-behavior={ignore,maytrap,strict} allows the user to specify
-  the floating-point exception behavior. The default setting is ``ignore``.
-
-- -ffp-model={precise,strict,fast} provides the user an umbrella option to
-  simplify access to the many single purpose floating point options. The default
-  setting is ``precise``.
-
-- The default module cache has moved from /tmp to a per-user cache directory.
-  By default, this is ~/.cache but on some platforms or installations, this
-  might be elsewhere. The -fmodules-cache-path=... flag continues to work.
-
-- -fpch-instantiate-templates tries to instantiate templates already while
-  generating a precompiled header. Such templates do not need to be
-  instantiated every time the precompiled header is used, which saves compile
-  time. This may result in an error during the precompiled header generation
-  if the source header file is not self-contained. This option is enabled
-  by default for clang-cl.

 Deprecated Compiler Flags

 Modified Compiler Flags
 -----------------------
 
-- -fno-common has been enabled as the default for all targets.  Therefore, C
-  code that uses tentative definitions as definitions of a variable in multiple
-  translation units will trigger multiple-definition linker errors. Generally,
-  this occurs when the use of the ``extern`` keyword is neglected in the
-  declaration of a variable in a header file. In some cases, no specific
-  translation unit provides a definition of the variable. The previous
-  behavior can be restored by specifying ``-fcommon``.
-- -Wasm-ignored-qualifier (ex. `asm const ("")`) has been removed and replaced
-  with an error (this matches a recent change in GCC-9).
-- -Wasm-file-asm-volatile (ex. `asm volatile ("")` at global scope) has been
-  removed and replaced with an error (this matches GCC's behavior).
-- Duplicate qualifiers on asm statements (ex. `asm volatile volatile ("")`) no
-  longer produces a warning via -Wduplicate-decl-specifier, but now an error
-  (this matches GCC's behavior).
-- The deprecated argument ``-f[no-]sanitize-recover`` has changed to mean
-  ``-f[no-]sanitize-recover=all`` instead of
-  ``-f[no-]sanitize-recover=undefined,integer`` and is no longer deprecated.
-- The argument to ``-f[no-]sanitize-trap=...`` is now optional and defaults to
-  ``all``.
-- ``-fno-char8_t`` now disables the ``char8_t`` keyword, not just the use of
-  ``char8_t`` as the character type of ``u8`` literals. This restores the
-  Clang 8 behavior that regressed in Clang 9 and 10.

 C++ Language Changes in Clang
 -----------------------------
 
-- Clang now implements a restriction on giving non-C-compatible anonymous
-  structs a typedef name for linkage purposes, as described in C++ committee
-  paper `P1766R1 <http://wg21.link/p1766r1>`. This paper was adopted by the
-  C++ committee as a Defect Report resolution, so it is applied retroactively
-  to all C++ standard versions. This affects code such as:
-
-  .. code-block:: c++
-
-    typedef struct {
-      int f() { return 0; }
-    } S;
-
-  Previous versions of Clang rejected some constructs of this form
-  (specifically, where the linkage of the type happened to be computed
-  before the parser reached the typedef name); those cases are still rejected
-  in Clang 11. In addition, cases that previous versions of Clang did not
-  reject now produce an extension warning. This warning can be disabled with
-  the warning flag ``-Wno-non-c-typedef-for-linkage``.
-
-  Affected code should be updated to provide a tag name for the anonymous
-  struct:
-
-  .. code-block:: c++
-
-    struct S {
-      int f() { return 0; }
-    };
-
-  If the code is shared with a C compilation (for example, if the parts that
-  are not C-compatible are guarded with ``#ifdef __cplusplus``), the typedef
-  declaration should be retained, but a tag name should still be provided:
-
-  .. code-block:: c++
-
-    typedef struct S {
-      int f() { return 0; }

-- ``RecursiveASTVisitor`` no longer calls separate methods to visit specific
-  operator kinds. Previously, ``RecursiveASTVisitor`` treated unary, binary,
-  and compound assignment operators as if they were subclasses of the
-  corresponding AST node. For example, the binary operator plus was treated as
-  if it was a ``BinAdd`` subclass of the ``BinaryOperator`` class: during AST
-  traversal of a ``BinaryOperator`` AST node that had a ``BO_Add`` opcode,
-  ``RecursiveASTVisitor`` was calling the ``TraverseBinAdd`` method instead of
-  ``TraverseBinaryOperator``. This feature was contributing a non-trivial
-  amount of complexity to the implementation of ``RecursiveASTVisitor``, it was
-  used only in a minor way in Clang, was not tested, and as a result it was
-  buggy. Furthermore, this feature was creating a non-uniformity in the API.
-  Since this feature was not documented, it was quite difficult to figure out
-  how to use ``RecursiveASTVisitor`` to visit operators.
-
-  To update your code to the new uniform API, move the code from separate
-  visitation methods into methods that correspond to the actual AST node and
-  perform case analysis based on the operator opcode as needed:
-
-  * ``TraverseUnary*() => TraverseUnaryOperator()``
-  * ``WalkUpFromUnary*() => WalkUpFromUnaryOperator()``

 Changes to the LLVM IR
 ----------------------
 
-* The callsite attribute `vector-function-abi-variant
-  <https://llvm.org/docs/LangRef.html#call-site-attributes>`_ has been
-  added to describe the mapping between scalar functions and vector
-  functions, to enable vectorization of call sites. The information
-  provided by the attribute is interfaced via the API provided by the
-  ``VFDatabase`` class.
-
-* `dereferenceable` attributes and metadata on pointers no longer imply
-  anything about the alignment of the pointer in question. Previously, some
-  optimizations would make assumptions based on the type of the pointer. This
-  behavior was undocumented. To preserve optimizations, frontends may need to
-  be updated to generate appropriate `align` attributes and metadata.
-
-* The DIModule metadata is extended to contain file and line number
-  information. This information is used to represent Fortran modules debug
-  info at IR level.

@@ -82,21 +67,6 @@ Changes to the ARM Backend
 
 During this release ...
 
-* Implemented C-language intrinsics for the full Arm v8.1-M MVE instruction
-  set. ``<arm_mve.h>`` now supports the complete API defined in the Arm C
-  Language Extensions.
-
-* Added support for assembly for the optional Custom Datapath Extension (CDE)
-  for Arm M-profile targets.
-
-* Implemented C-language intrinsics ``<arm_cde.h>`` for the CDE instruction set.
-
-* Clang now defaults to ``-fomit-frame-pointer`` when targeting non-Android
-  Linux for arm and thumb when optimizations are enabled. Users that were
-  previously not specifying a value and relying on the implicit compiler
-  default may wish to specify ``-fno-omit-frame-pointer`` to get the old
-  behavior. This improves compatibility with GCC.

 Changes to the MIPS Target
 --------------------------
 
@@ -113,45 +83,20 @@ Changes to the X86 Target
 
 During this release ...
 
-
-* Functions with the probe-stack attribute set to "inline-asm" are now protected
-  against stack clash without the need of a third-party probing function and
-  with limited impact on performance.
-* -x86-enable-old-knl-abi command line switch has been removed. v32i16/v64i8
-  vectors are always passed in ZMM register when avx512f is enabled and avx512bw
-  is disabled.
-* Vectors larger than 512 bits with i16 or i8 elements will be passed in
-  multiple ZMM registers when avx512f is enabled. Previously this required
-  avx512bw otherwise they would split into multiple YMM registers. This means
-  vXi16/vXi8 vectors are consistently treated the same as
-  vXi32/vXi64/vXf64/vXf32 vectors of the same total width.
-
 Changes to the AMDGPU Target
 -----------------------------
 
-* The backend default denormal handling mode has been switched to on
-  for all targets for all compute function types. Frontends wishing to
-  retain the old behavior should explicitly request f32 denormal
-  flushing.
+During this release ...
 
 Changes to the AVR Target
 -----------------------------
 
-* Moved from an experimental backend to an official backend. AVR support is now
-  included by default in all LLVM builds and releases and is available under
-  the "avr-unknown-unknown" target triple.
+During this release ...
 
 Changes to the WebAssembly Target
 ---------------------------------
 
-* Programs which don't have a "main" function, called "reactors" are now
-  properly supported, with a new `-mexec-model=reactor` flag. Programs which
-  previously used `-Wl,--no-entry` to avoid having a main function should
-  switch to this new flag, so that static initialization is properly
-  performed.
-
-* `__attribute__((visibility("protected")))` now evokes a warning, as
-  WebAssembly does not support "protected" visibility.

 Changes to the Debug Info
 ---------------------------------
 
-* LLVM now supports the debug entry values (DW_OP_entry_value) production for
-  the x86, ARM, and AArch64 targets by default. Other targets can use
-  the utility by using the experimental option ("-debug-entry-values").
-  This is a debug info feature that allows debuggers to recover the value of
-  optimized-out parameters by going up a stack frame and interpreting the values
-  passed to the callee. The feature improves the debugging user experience when
-  debugging optimized code.
+During this release ...
 
 Changes to the LLVM tools
 ---------------------------------
 
-* Added an option (--show-section-sizes) to llvm-dwarfdump to show the sizes
-  of all debug sections within a file.
-
-* llvm-nm now implements the flag ``--special-syms`` and will filter out special
-  symbols, i.e. mapping symbols on ARM and AArch64, by default. This matches
-  the GNU nm behavior.

 mode

Summary:
I hit this while trying to add a config-over-LSP lit test, which I think
is an appropriate way to test this feature.

That needs a few more changes though...

Subject: [PATCH 367/771] [LoopRotate] Remove unnecessary verifyMemorySSA
 calls.

The actual rotation happens in processLoop, so the second removed
call to verifyMemorySSA was unnecessary.

In fact, processLoop/rotateLoop already verify MemorySSA before
and after transforming each loop. Hence, both calls can be removed.

Pointed out by @lebedev.ri post-commit D51718.

Subject: [PATCH 370/771] [RISCV] Add matching of codegen patterns to RISCV Bit
 Manipulation Zbb asm instructions

This patch provides optimization of bit manipulation operations by
enabling the +experimental-b target feature.
It adds matching of single block patterns of instructions to specific
bit-manip instructions from the base subset (zbb subextension) of the
experimental B extension of RISC-V.
It adds also the correspondent codegen tests.

This patch is based on Claire Wolf's proposal for the bit manipulation
extension of RISCV:
https://github.com/riscv/riscv-bitmanip/blob/master/bitmanip-0.92.pdf

Subject: [PATCH 371/771] [RISCV] Add matching of codegen patterns to RISCV Bit
 Manipulation Zbp asm instructions

This patch provides optimization of bit manipulation operations by
enabling the +experimental-b target feature.
It adds matching of single block patterns of instructions to specific
bit-manip instructions from the permutation subset (zbp subextension) of
the experimental B extension of RISC-V.
It adds also the correspondent codegen tests.

This patch is based on Claire Wolf's proposal for the bit manipulation
extension of RISCV:
https://github.com/riscv/riscv-bitmanip/blob/master/bitmanip-0.92.pdf

Subject: [PATCH 372/771] [RISCV] Add matching of codegen patterns to RISCV Bit
 Manipulation Zbbp asm instructions

This patch provides optimization of bit manipulation operations by
enabling the +experimental-b target feature.
It adds matching of single block patterns of instructions to specific
bit-manip instructions belonging to both the permutation and the base
subsets of the experimental B extension of RISC-V.
It adds also the correspondent codegen tests.

This patch is based on Claire Wolf's proposal for the bit manipulation
extension of RISCV:
https://github.com/riscv/riscv-bitmanip/blob/master/bitmanip-0.92.pdf

Subject: [PATCH 373/771] [RISCV] Add matching of codegen patterns to RISCV Bit
 Manipulation Zbs asm instructions

This patch provides optimization of bit manipulation operations by
enabling the +experimental-b target feature.
It adds matching of single block patterns of instructions to specific
bit-manip instructions from the single-bit subset (zbs subextension) of
the experimental B extension of RISC-V.
It adds also the correspondent codegen tests.

This patch is based on Claire Wolf's proposal for the bit manipulation
extension of RISCV:

Subject: [PATCH 374/771] [RISCV] Add matching of codegen patterns to RISCV Bit
 Manipulation Zbt asm instructions

This patch provides optimization of bit manipulation operations by
enabling the +experimental-b target feature.
It adds matching of single block patterns of instructions to specific
bit-manip instructions from the ternary subset (zbt subextension) of the
experimental B extension of RISC-V.
It adds also the correspondent codegen tests.

This patch is based on Claire Wolf's proposal for the bit manipulation
extension of RISCV:
https://github.com/riscv/riscv-bitmanip/blob/master/bitmanip-0.92.pdf

Subject: [PATCH 375/771] [mips] Rename FeatureMadd4 to FeatureNoMadd4. NFC

`FeatureMadd4` is used to disable `madd4`, and the corresponding feature
option is `(+-)nomadd4`. Renaming to the `FeatureNoMadd4` makes its
purpose clear.

Patch by YunQiang Su.

Subject: [PATCH 376/771] [lldb] Use the basename of the Python test for the
 log name instead of the class name

Summary:

From what I know we already have the restriction that every test in the test
suite needs to have a unique file name as that's used for generating the unique
build directory for a test. It seems there is also a restriction that every test
case class in the test suite needs to have a unique name as that's used to
generate the unique log file name for the test run.

This changes the log file format to use the basename of the test file instead so
that we only have to keep worrying about the 'unique file name' restriction from
now on.

This came up because I started naming the test classes "TestCase" (as repeating
the file name in the test class seems like redudant information that just makes
renaming tests a pain).

Subject: [PATCH 377/771] [lldb] Make expect_expr fall back to the dummy target
 if no target is selected

Summary:

Currently expect_expr will not run the expression if no target is selected. This
patch changes this behavior so that expect_expr will instead fall back to the
dummy target similar to what the `expression` command is doing. This way we
don't have to compile an empty executable to be able to use `expect_expr` (which
is a waste of resources for tests that just test generic type system features).

As a test I modernized the TestTypeOfDeclTypeExpr into a Python test +
expect_expr (as it relied on the dummy target fallback of the expression
command).

Subject: [PATCH 380/771] [lldb/test] Remove JOIN_CMD from Makefile.rules

It's possible to achieve the same effect by providing multi-step recipe
instead of a single-step recipe where the step happens to contain
multiple commands.

Subject: [PATCH 381/771] CodeGenPrep: remove AssertingVH references before
 deleting dead instructions.

CodeGenPrepare keeps fairly close track of various instructions it's
seen, particularly GEPs, in maps and vectors. However, sometimes those
instructions become dead and get removed while it's still executing.
This triggers AssertingVH references to them in an asserts build and
could lead to miscompiles in a release build (I've only seen a later
segfault though).

So this patch adds a callback to
RecursivelyDeleteTriviallyDeadInstructions which can make sure the
instruction about to be deleted is removed from CodeGenPrepare's data
structures.

Subject: [PATCH 382/771] Revert "[lldb] Use the basename of the Python test
 for the log name instead of the class name"

This reverts commit 29aab9b5c748b28b231e2ca0f9b95453638ade1a.

It seems on Windows the file name is just always "lldbsuite.test.lldbtest" for
all tests and that breaks pretty much everything. Reverting until we have
a better solution.

Subject: [PATCH 383/771] [TSan] Optimize handling of racy address

This patch splits the handling of racy address and racy stack into separate
functions. If a race was already reported for the address, we can avoid the
cost for collecting the involved stacks.

This patch also removes the race condition in storing the racy address / racy
stack. This race condition allowed all threads to report the race.

This patch changes the transitive suppression of reports. Previously
suppression could transitively chain memory location and racy stacks.
Now racy memory and racy stack are separate suppressions.

Subject: [PATCH 386/771] [MLIR][Shape] Fix `shape_of` lowering to `scf`

The use of the `scf.for` callback builder does not allow for a rollback of the
emitted conversions. Instead, we populate the loop body through the conversion
rewriter directly.

Subject: [PATCH 388/771] [lldb/Test] Remove support for forking a subprocess
 from the test suite.

Remove the forkSubprocess method and its bookkeeping.
TestCreateAfterAttach is the only test using the fork method and I'm not
convinced it adds enough to warrant the maintenance. Pavel suggested the
same thing in D83815.

Subject: [PATCH 392/771] [lldb][test] Prevent infinite loop while looking for
 use_lldb_suite_root.py.

Several scripts (two copies of use_lldb_suite.py, and an __init__.py) look for use_lldb_suite_root.py by checking parent directories. If for some reason it doesn't exist, it keeps checking parent directories until it finds it.

However, this only breaks when the parent directory is None, but at least on Linux, dirname('/') == '/', so this will never be None.

This changes the lookup to stop if the dirname(lldb_root) is unchanged. This was previously fixed in 67f6d842fab6d3ac8c949721be8e131cf6b17578, but only in one copy of this script.

Additionally, this makes the failure mode more visible -- if the root is not found, it complains loudly instead of silently failing, and having later modules that need lldb_root fail.

Subject: [PATCH 393/771] [CMake][runtimes] Pass the CMAKE_ARGS to runtimes
 build correctly

We were relying on CMAKE_ARGS argument to be passed to subbuild, but
this argument was never properly defined. This patch addresses that.

Subject: [PATCH 396/771] [AMDGPU][MC] Corrected MTBUF parsing and decoding

MTBUF implementation has many issues and this change addresses most of these:
- refactored duplicated code;
- hardcoded constants moved out of high-level code;
- fixed a decoding error when nfmt or dfmt are zero (bug 36932);
- corrected parsing of operand separators (bug 46403);
- corrected handling of missing operands (bug 46404);
- corrected handling of out-of-range modifiers (bug 46421);
- corrected default value (bug 46467).

Subject: [PATCH 397/771] [mlir][shape] Fold shape.broadcast with one scalar
 operand

This folds shape.broadcast where at least one operand is a scalar to the
other operand.

Also add an assemblyFormat for shape.broadcast and shape.concat.

Subject: [PATCH 399/771] [PGO] Extend the value profile buckets for mem op
 sizes.

Extend the memop value profile buckets to be more flexible (could accommodate a
mix of individual values and ranges) and to cover more value ranges (from 11 to
22 buckets).

Disabled behind a flag (to be enabled separately) and the existing code to be
removed later.

Subject: [PATCH 401/771] [InstCombine] update datalayout in test file; NFC

We need to specify legal integer widths to trigger PR46712,
so add those here. This doesn't appear to affect any existing
tests, and it's not clear why a datalayout would not include
any legal integer widths.

While here, change some variable names that include 'tmp' to
avoid warnings from the auto-generating script for CHECK lines.

Subject: [PATCH 403/771] [MLIR] Add type checking capability to
 RegionBranchOpInterface

- Add function `verifyTypes` that Op's can call to do type checking verification
  along the control flow edges described the Op's RegionBranchOpInterface.
- We cannot rely on the verify methods on the OpInterface because the interface
  functions assume valid Ops, so they may crash if invoked on unverified Ops.
  (For example, scf.for getSuccessorRegions() calls getRegionIterArgs(), which
  dereferences getBody() block. If the scf.for is invalid with no body, this
  can lead to a segfault). `verifyTypes` can be called post op-verification to
  avoid this.

Subject: [PATCH 405/771] [lldb][NFC] Add 'override' where missing in source/
 and tools/

These were found by Clang's new -Wsuggest-override.

This patch doesn't touch any code in unittests/, since much of it intentionally doesn't use override to avoid massive warning spam from -Winconsistent-missing-override due to the use of MOCK_*** macros.

Subject: [PATCH 407/771] [OPENMP]Fix PR46688: cast the type of the allocated
 variable to the initial one.

Summary:
If the original variable is marked for allocation in the different
address space using #pragma omp allocate, need to cast the allocated
variable to its original type with the original address space.
Otherwise, the compiler may crash trying to bitcast the type of the new
allocated variable to the original type in some cases, like passing this
variable as an argument in function calls.

Subject: [PATCH 411/771] [LoopUnroll] Update branch weight for remainder loop

Unrolling a loop with compile-time unknown trip count results in a remainder loop. The remainder loop executes the remaining iterations of the original loop when the original trip count is not a multiple of the unroll factor. For better profile counts maintenance throughout the optimization pipeline, I'm assigning an artificial weight to the latch branch of the remainder loop.

A remainder loop runs up to as many times as the unroll factor subtracted by 1. Therefore I'm assigning the maximum possible trip count as the back edge weight. This should be more accurate than the default non-profile weight, which assumes the back edge runs much more frequently than the exit edge.

Subject: [PATCH 412/771] [flang] Fix erroneous application of SAVE statement

A SAVE statement with no entity list applies the SAVE attribute only to
the entities that it is allowed on. We were applying it to automatic
data objects and reporting an error that they can't have SAVE.

The fix is to change `DeclarationVisitor::CheckSaveAttr` to check for
automatic objects. That controls both checking and setting the
attribute. This allows us to remove the check from `CheckSpecExpr`
(along with `symbolBeingChecked_`). Also, it was only called on constant
objects so the non-const overload can be eliminated.

The check in `CheckSpecExpr` is replaced by an explicit check for
automatic objects in modules. This caught an error in modfile03.f90 so
that part of the test was eliminated.

Subject: [PATCH 414/771] [lldb/Test] Remove custom tearDownHooks from GDB
 Remote tests

Remove custom tearDownHooks from GDB Remote tests as we now cleanup
subprocesses unconditionally. This also changes the termination order to
be the reverse of the creation order. I don't think anything is relying
on that right now, but it better fits the setup/teardown paradigm.

Subject: [PATCH 415/771] Clarify a bit the guideline on omitting braces,
 including more examples (NFC)

Like most readability rules, it isn't absolute and there is a matter of taste
to it. I think more recent part of the project may be more consistent in the
current application of the guideline. I suspect sources like
mlir/lib/Dialect/StandardOps/IR/Ops.cpp may be examples of this at the moment.

 x86 for the jitlinker

Summary: This adds the basic support for GOT in elf x86.
Was able to just get away using the macho code by generalising the edges.
There will be a follow up patch to turn that into a generic utility for both of the x86 and Mach-O code.

This patch also lands support for relocations relative to symbol.

Subject: [PATCH 425/771] [MLIR] Add RegionKindInterface

Some dialects have semantics which is not well represented by common
SSA structures with dominance constraints.  This patch allows
operations to declare the 'kind' of their contained regions.
Currently, two kinds are allowed: "SSACFG" and "Graph".  The only
difference between them at the moment is that SSACFG regions are
required to have dominance, while Graph regions are not required to
have dominance.  The intention is that this Interface would be
generated by ODS for existing operations, although this has not yet
been implemented. Presumably, if someone were interested in code
generation, we might also have a "CFG" dialect, which defines control
flow, but does not require SSA.

The new behavior is mostly identical to the previous behavior, since
registered operations without a RegionKindInterface are assumed to
contain SSACFG regions.  However, the behavior has changed for
unregistered operations.  Previously, these were checked for
dominance, however the new behavior allows dominance violations, in
order to allow the processing of unregistered dialects with Graph
regions.  One implication of this is that regions in unregistered
operations with more than one op are no longer CSE'd (since it
requires dominance info).

I've also reorganized the LangRef documentation to remove assertions
about "sequential execution", "SSA Values", and "Dominance".  Instead,
the core IR is simply "ordered" (i.e. totally ordered) and consists of
"Values".  I've also clarified some things about how control flow
passes between blocks in an SSACFG region. Control Flow must enter a
region at the entry block and follow terminator operation successors
or be returned to the containing op.  Graph regions do not define a
notion of control flow.

see discussion here:
https://llvm.discourse.group/t/rfc-allowing-dialects-to-relax-the-ssa-dominance-condition/833/53

+#### Operation Interface List
+
+MLIR includes standard interfaces providing functionality that is
+likely to be common across many different operations. Below is a list
+of some key interfaces that may be used directly by any dialect. The
+format of the header for each interface section goes as follows:
+
+*   `Interface class name`
+    -   (`C++ class` -- `ODS class`(if applicable))
+
+##### CallInterfaces
+
+*   `CallOpInterface` - Used to represent operations like 'call'
+    -   `CallInterfaceCallable getCallableForCallee()`
+*   `CallableOpInterface` - Used to represent the target callee of call.
+    -   `Region * getCallableRegion()`
+    -   `ArrayRef<Type> getCallableResults()`
+
+##### RegionKindInterfaces
+
+*   `RegionKindInterface` - Used to describe the abstract semantics of regions.
+     - `RegionKind getRegionKind(unsigned index)` - Return the kind of the region with the given index inside this operation.
+         - RegionKind::Graph - represents a graph region without control flow semantics
+         - RegionKind::SSACFG - represents an [SSA-style control flow](LangRef.md#modeling-control-flow) region with basic blocks and reachability
+     - `hasSSADominance(unsigned index)` - Return true if the region with the given index inside this operation requires dominance.

 ## High-Level Structure
 
-MLIR is an
+MLIR is fundamentally based on a graph-like data structure of nodes, called
+*Operations*, and edges, called *Values*. Each Value is the result of exactly
+one Operation or Block Argument, and has a *Value Type* defined by the [type
+system](#type-system).  [Operations](#operations) are contained in
+[Blocks](#blocks) and Blocks are contained in [Regions](#regions). Operations
+are also ordered within their containing block and Blocks are ordered in their
+containing region, although this order may or may not be semantically
+meaningful in a given [kind of region](Interfaces.md#regionkindinterface)).
+Operations may also contain regions, enabling hierarchical structures to be
+represented.
+
+Operations can represent many different concepts, from higher-level concepts
+like function definitions, function calls, buffer allocations, view or slices
+of buffers, and process creation, to lower-level concepts like
+target-independent arithmetic, target-specific instructions, configuration
+registers, and logic gates. These different concepts are represented by
+different operations in MLIR and the set of operations usable in MLIR can be
+arbitrarily extended.
+
+MLIR also provides an extensible framework for transformations on operations,
+using familiar concepts of compiler [Passes](Passes.md). Enabling an arbitrary
+set of passes on an arbitrary set of operations results in a significant
+scaling challenge, since each transformation must potentially take into
+account the semantics of any operation. MLIR addresses this complexity by
+allowing operation semantics to be described abstractly using
+[Traits](Traits.md) and [Interfaces](Interfaces.md), enabling transformations
+to operate on operations more generically.  Traits often describe verification
+constraints on valid IR, enabling complex invariants to be captured and
+checked. (see
+[docs/Tutorials/Toy/Ch-2/#op-vs-operation-using-mlir-operations])
+
+One obvious application of MLIR is to represent an
 [SSA-based](https://en.wikipedia.org/wiki/Static_single_assignment_form) IR,
-which means that values are defined before use and have scope defined by their
-dominance relations. Operations may produce zero or more results, and each is a
-distinct SSA value with its own type defined by the [type system](#type-system).
-
-The unit of code in MLIR is an [Operation](#operations). Operations allow for
-representing many different concepts: allocating buffers, producing views to
-transform them, target-independent arithmetic, target-specific operations, and
-even arbitrary user-defined high-level operations including the
-[Module](#module) and [Function](#functions) operations. Operations may contain

 ## Regions
 
 ### Definition
 
-A region is a CFG of MLIR [Blocks](#blocks). Regions serve to group semantically
-connected blocks, where the semantics is not imposed by the IR. Instead, the
-containing operation defines the semantics of the regions it contains. Regions
-do not have a name or an address, only the blocks contained in a region do.
-Regions are meaningless outside of the containing entity and have no type or
-attributes.
+A region is an ordered list of MLIR [Blocks](#blocks). The semantics within a
+region is not imposed by the IR. Instead, the containing operation defines the
+semantics of the regions it contains. MLIR currently defines two kinds of
+regions: [SSACFG regions](#control-flow-and-ssacfg-regions), which describe
+control flow between blocks, and [Graph regions](#graph-regions), which do not
+require control flow between block. The kinds of regions within an operation
+are described using the
+[RegionKindInterface](Interfaces.md#regionkindinterface).
 
-The first block in the region cannot be a successor of any other block. The
-syntax for the region is as follows:
+Regions do not have a name or an address, only the blocks contained in a
+region do. Regions must be contained within operations and have no type or
+attributes. The first block in the region is a special block called the 'entry
+block'. The arguments to the entry block are also the arguments of the region
+itself. The entry block cannot be listed as a successor of any other
+block. The syntax for a region is as follows:
 
 ```
 region ::= `{` block* `}`
 ```
 
-The function body is an example of a region: it consists of a CFG of blocks and
-has additional semantic restrictions that other types of regions may not have
-(block terminators must either branch to a different block, or return from a
-function where the types of the `return` arguments must match the result types
-of the function signature).
+A function body is an example of a region: it consists of a CFG of blocks and
+has additional semantic restrictions that other types of regions may not have.
+For example, in a function body, block terminators must either branch to a
+different block, or return from a function where the types of the `return`
+arguments must match the result types of the function signature.  Similarly,
+the function arguments must match the types and count of the region arguments.
+In general, operations with regions can define these correspondances
+arbitrarily.
+
+### Value Scoping
+
+Regions provide hierarchical encapsulation of programs: it is impossible to
+reference, i.e. branch to, a block which is not in the same region as the
+source of the reference, i.e. a terminator operation. Similarly, regions
+provides a natural scoping for value visibility: values defined in a region
+don't escape to the enclosing region, if any. By default, operations inside a
+region can reference values defined outside of the region whenever it would
+have been legal for operands of the enclosing operation to reference those
+values, but this can be restricted using traits, such as
+[OpTrait::IsolatedFromAbove](Traits.md#isolatedfromabove), or a custom
+verifier.
 
-### Control and Value Scoping
+Example:
 
-Regions provide nested control isolation: it is impossible to branch to a block
-within a region from outside it or to branch from within a region to a block
-outside it. Similarly, it provides a natural scoping for value visibility: SSA
-values defined in a region don't escape to the enclosing region, if any. By
-default, a region can reference values defined outside of the region whenever it
-would have been legal to use them as operands to the enclosing operation.
+```mlir
+  "any_op"(%a) ({ // if %a is in-scope in the containing region...
+	 // then %a is in-scope here too.
+    %new_value = "another_op"(%a) : (i64) -> (i64)
+  }) : (i64) -> (i64)
+```
+
+MLIR defines a generalized 'hierarchical dominance' concept that operates
+across hierarchy and defines whether a value is 'in scope' and can be used by
+a particular operation. Whether a value can be used by another operation in
+the same region is defined by the kind of region. A value defined in a region
+can be used by an operation which has a parent in the same region, if and only
+if the parent could use the value. A value defined by an argument to a region
+can always be used by any operation deeply contained in the region. A value
+defined in a region can never be used outside of the region.
+
+### Control Flow and SSACFG Regions
+
+In MLIR, control flow semantics of a region is indicated by
+[RegionKind::SSACFG](Interfaces.md#regionkindinterface).  Informally, these
+regions support semantics where operations in a region 'execute
+sequentially'. Before an operation executes, its operands have well-defined
+values. After an operation executes, the operands have the same values and
+results also have well-defined values. After an operation executes, the next
+operation in the block executes until the operation is the terminator operation
+at the end of a block, in which case some other operation will execute. The
+determination of the next instruction to execute is the 'passing of control
+flow'.
+
+In general, when control flow is passed to an operation, MLIR does not
+restrict when control flow enters or exits the regions contained in that
+operation. However, when control flow enters a region, it always begins in the
+first block of the region, called the *entry* block.  Terminator operations
+ending each block represent control flow by explicitly specifying the
+successor blocks of the block. Control flow can only pass to one of the
+specified successor blocks as in a `branch` operation, or back to the
+containing operation as in a `return` operation. Terminator operations without
+successors can only pass control back to the containing operation. Within
+these restrictions, the particular semantics of terminator operations is
+determined by the specific dialect operations involved. Blocks (other than the
+entry block) that are not listed as a successor of a terminator operation are
+defined to be unreachable and can be removed without affecting the semantics
+of the containing operation.
+
+Although control flow always enters a region through the entry block, control
+flow may exit a region through any block with an appropriate terminator. The
+standard dialect leverages this capability to define operations with
+Single-Entry-Multiple-Exit (SEME) regions, possibly flowing through different
+blocks in the region and exiting through any block with a `return`
+operation. This behavior is similar to that of a function body in most
+programming languages. In addition, control flow may also not reach the end of
+a block or region, for example if a function call does not return.

-
-### Control Flow
-
-Regions are Single-Entry-Multiple-Exit (SEME). This means that control can only
-flow into the first block of the region, but can flow out of the region at the
-end of any of the contained blocks (This behavior is similar to that of a
-function body in most programming languages). A terminator of a block within a
-region may transfer the control flow to another block in this region, or return
-it to the immediately enclosing op. The semantics of the enclosing op defines
-where the control flow is transmitted next. It may, for example, enter a region
-of the same op, including the same region that returned the control flow.
-
-The enclosing operation determines the way in which control is transmitted into
-the entry block of a Region. The successor to a Region’s exit points may not
-necessarily exist: for example a call to a function that does not return.
-Concurrent or asynchronous execution of Regions is unspecified. Operations may
-define specific rules of execution, e.g. sequential loops or switch cases.
-
-A Region may also enter another region within the enclosing operation. If an
-operation has multiple regions, the semantics of the operation defines into
-which regions the control flows and in which order, if any. An operation may
-transmit control into Regions that were specified in other operations, in
-particular those that defined the values the given operation uses. Thus, such
-operations can be treated opaquely in the enclosing control flow graph,
-providing a level of control flow isolation similar to that of the call
-operation.
+#### Operations with Multiple Regions
+
+An operation containing multiple regions also completely determines the
+semantics of those regions. In particular, when control flow is passed to an
+operation, it may transfer control flow to any contained region. When control
+flow exits a region and is returned to the containing operation, the
+containing operation may pass control flow to any region in the same
+operation. An operation may also pass control flow to multiple contained
+regions concurrently. An operation may also pass control flow into regions
+that were specified in other operations, in particular those that defined the
+values or symbols the given operation uses as in a call operation. This
+passage of control is generally independent of passage of control flow through
+the basic blocks of the containing region.

+### Graph Regions
+
+In MLIR, graph-like semantics in a region is indicated by
+[RegionKind::Graph](Interfaces.md#regionkindinterface). Graph regions are
+appropriate for concurrent semantics without control flow, or for modeling
+generic directed graph data structures. Graph regions are appropriate for
+representing cyclic relationships between coupled values where there is no
+fundamental order to the relationships. For instance, operations in a graph
+region may represent independent threads of control with values representing
+streams of data. As usual in MLIR, the particular semantics of a region is
+completely determined by its containing operation. Graph regions may only
+contain a single basic block (the entry block).
+
+**Rationale:** Currently graph regions are arbitrarily limited to a single
+basic block, although there is no particular semantic reason for this
+limitation. This limitation has been added to make it easier to stabilize the
+pass infrastructure and commonly used passes for processing graph regions to
+properly handle feedback loops. Multi-block regions may be allowed in the
+future if use cases that require it arise.
+
+In graph regions, MLIR operations naturally represent nodes, while each MLIR
+value represents a multi-edge connecting a single source node and multiple
+destination nodes. All values defined in the region as results of operations
+are in scope within the region and can be accessed by any other operation in
+the region. In graph regions, the order of operations within a block and the
+order of blocks in a region is not semantically meaningful and non-terminator
+operations may be freely reordered, for instance, by canonicalization. Other
+kinds of graphs, such as graphs with multiple source nodes and multiple
+destination nodes, can also be represented by representing graph edges as MLIR
+operations.
+
+Note that cycles can occur within a single block in a graph region, or between
+basic blocks.

Subject: [PATCH 427/771] [CodeGen] Emit a call instruction instead of an
 invoke if the called llvm function is marked nounwind

This fixes cases where an invoke is emitted, despite the called llvm
function being marked nounwind, because ConstructAttributeList failed to
add the attribute to the attribute list. llvm optimization passes turn
invokes into calls and optimize away the exception handling code, but
it's better to avoid emitting the code in the front-end if the called
function is known not to raise an exception.

Subject: [PATCH 428/771] [flang] Don't use-associate intrinsics

When an intrinsic is referenced in a module scope, a symbol for it is
added. When that module is USEd, the intrinsic should not be included.
Otherwise we can get ambiguous reference errors with the same intrinsic
coming from two difference modules.

Subject: [PATCH 429/771] [X86] Teach assembler parser to accept lsl and lar
 with a 64 or 32 source register when the destination is a 64 register.

Previously we only accepted a 32-bit source with a 64-bit dest.

Accepting 64-bit as well is more consistent with gas behavior. I
think maybe we should accept 16 bit register as well, but I'm not
sure.

Subject: [PATCH 431/771] [NFCI] createCFGSimplificationPass(): migrate to also
 take SimplifyCFGOptions

Taking so many parameters is simply unmaintainable.

We don't want to include the entire llvm/Transforms/Utils/Local.h into
llvm/Transforms/Scalar.h so i've split SimplifyCFGOptions into
it's own header.

Summary:
test_terminate_commands is flaky on LLDB Arm buildbot as well. It was already
being skipped for aarch64. I am going to mark it skipped for Arm too.

Subject: [PATCH 437/771] [CalcSpillWeights] Propagate the fact that a
 live-interval is not spillable

When we calculate the weight of a live-interval, add some code to
check if the original live-interval was markied as not spillable and
if so, progagate that information down to the new interval.

Previously we would just recompute a weight for the new interval,
thus, we could in theory just spill live-intervals marked as not
spillable by just splitting them. That goes against the spirit of
a non-spillable live-interval.

E.g., previously we could do:
v1 =  // v1 must not be spilled
...
= v1

Split:
v1 = // v1 must not be spilled
...
v2 = v1 // v2 can be spilled
...
v3 = v2 // v3 can be spilled
= v3

There's no test case for that one as we would need to split a
non-spillable live-interval without using LiveRangeEdit to see this
happening.
RegAlloc inserts non-spillable intervals only as part of the spilling
mechanism, thus at this point the intervals are not splittable anymore.
On top of that, RegAlloc uses the LiveRangeEdit API, which already
properly propagate that information.

In other words, this could only happen if a target was to mark
a live-interval as not spillable before register allocation and
split it without using LRE, e.g., through
LiveIntervals::splitSeparateComponent.

Subject: [PATCH 440/771] [libunwind] Fix CIE v1 return address parsing

 - For CIE version 1 (e.g. in DWARF 2.0.0), the return_address_register
   field is a ubyte [0..255].

 - For CIE version 3 (e.g. in DWARF 3), the field is instead a ULEB128
   constant.

Previously, libunwind accepted a CIE version of 1 or 3, but always
parsed the field as ULEB128.

Clang always outputs CIE version 1 into .eh_frame. (It can output CIE
version 3 or 4, but only into .debug_frame.)

Subject: [PATCH 441/771] [libunwind] Fix getSLEB128 on large values

Previously, for large-enough values, getSLEB128 would attempt to shift
a signed int in the range [0..0x7f] by 28, 35, 42... bits, which is
undefined behavior and likely to fail.

Avoid shifting (-1ULL) by 70 for large values. e.g. For INT64_MAX, the
last two bytes will be:
 - 0x7f [bit==56]
 - 0x00 [bit==63]

Subject: [PATCH 444/771] Standardize `linalg.generic` on `args_in`/`args_out`
 instead of `inputCount`/`outputCount`

 This also fixes the outdated use of `n_views` in the documentation.

Subject: [PATCH 446/771] Revert "[InstSimplify] Remove select ?, undef, X -> X
 and select ?, X, undef -> X transforms" and subsequent patches

This reverts most of the following patches due to reports of miscompiles.
I've left the added test cases with comments updated to be FIXMEs.

1cf6f210a2e [IR] Disable select ? C : undef -> C fold in ConstantFoldSelectInstruction unless we know C isn't poison.
469da663f2d [InstSimplify] Re-enable select ?, undef, X -> X transform when X is provably not poison
122b0640fc9 [InstSimplify] Don't fold vectors of partial undef in SimplifySelectInst if the non-undef element value might produce poison
ac0af12ed2f [InstSimplify] Add test cases for opportunities to fold select ?, X, undef -> X when we can prove X isn't poison
9b1e95329af [InstSimplify] Remove select ?, undef, X -> X and select ?, X, undef -> X transforms

Subject: [PATCH 447/771] [InstCombine] Simplify boolean Phis with const inputs
 using CFG

This patch adds simplification for pattern:
```
  if (cond)
  /       \
 ...      ...
  \       /
p = phi [true] [false]
...
br p, succ_1, succ_2
```
If we can prove that top block's branches dominate respective
inputs of a block that has a Phi with constant inputs, we can
use the branch condition (maybe inverted) instead of Phi.
This will make proofs of implication for further jump threading
more transparent.

From fc55308628709bfc64b100dadf9a030fbb2afaee Mon Sep 17 00:00:00 2001
From: Amy Kwan <amy.kwan1@ibm.com>
Date: Thu, 16 Jul 2020 00:10:54 -0500
Subject: [PATCH 448/771] [PowerPC][Power10] Fix VINS* (vector insert
 byte/half/word) instructions to have i32 arguments.

Previously, the vins* intrinsic was incorrectly defined to have its second and
third argument arguments as an i64. This patch fixes the second and third
argument of the vins* instruction and intrinsic to have i32s instead.

Differential Revision: https://reviews.llvm.org/D83497

Subject: [PATCH 449/771] Revert "[InstCombine] Simplify boolean Phis with
 const inputs using CFG"

This reverts commit 00472067c34ccbceb2fad4b905524f3c780bb7d5.

Need to fix failing clang tests.

Subject: [PATCH 450/771] [X86] Allow lsl/lar to be parsed with a GR16, GR32,
 or GR64 as source register.

This matches GNU assembler behavior. Operand size is determined
only from the destination register.

Subject: [PATCH 451/771] [lldb] Desugar template specializations

Template specializations are not handled in many of the
TypeSystemClang methods. For example, GetNumChildren does not handle
the TemplateSpecialization type class, so template specializations
always look like empty objects.

This patch just desugars template specializations in the existing
RemoveWrappingTypes desugaring helper.

Subject: [PATCH 452/771] [MasmParser] Remove unused method emitStructValue to
 silence warning

The method was added in bc8e262afe83 and has been unused ever since so
remove it to silence a gcc warning.

Subject: [PATCH 454/771] Revert "[NFC] SimplifyCFGOptions: drop
 multi-parameter ctor, use default member-init"

This reverts commit 90c1b0442a031d6cad686fdc4e5d3db03c3603a6.
This is based on another commit which also needs to be reverted.
The other commit introduced a Dependency Cycle between Transforms/Scalar
and TransformUtils. Scalar already depends (in many ways) on
TransformUtils, so making TransformUtils depend on Scalar should be
avoided.

Subject: [PATCH 455/771] Revert "[NFCI] createCFGSimplificationPass(): migrate
 to also take SimplifyCFGOptions"

This reverts commit b2018198c32a0535bb1f5bb5b40fbcf50d8d47b7.
This commit introduced a Dependency Cycle between Transforms/Scalar and
Transforms/Utils. Transforms/Scalar already depends on Transforms/Utils,
so if SimplifyCFGOptions.h is moved to Scalar, and Utils/Local.h still
depends on it, we have a cycle.

Subject: [PATCH 460/771] [Matrix] Also run lowering during -O0.

Currently the backends cannot lower the matrix intrinsics directly and
rely on the lowering to vector instructions happening in the middle-end.
At the moment, this means the backend crashes when matrix types
extension code is compiled with -O0, e.g.
http://green.lab.llvm.org/green/job/test-suite-verify-machineinstrs-aarch64-O0-g/7902/

This patch enables also runs the lowering with -O0 in the middle-end as
a temporary solution. Long term, a lightweight version of the lowering
should run in the backend, on demand.

Subject: [PATCH 461/771] [SVE][CodeGen] Legalisation of masked loads and
 stores

Summary:
This patch modifies IncrementMemoryAddress to use a vscale
when calculating the new address if the data type is scalable.

Also adds tablegen patterns which match an extract_subvector
of a legal predicate type with zip1/zip2 instructions

Subject: [PATCH 462/771] [ARM] CSEL generation

This adds a peephole optimisation to turn a t2MOVccr that could not be
folded into any other instruction into a CSEL on 8.1-m. The t2MOVccr
would usually be expanded into a conditional mov, that becomes an IT;
MOV pair. We can instead generate a CSEL instruction, which can
potentially be smaller and allows better register allocation freedom,
which can help reduce codesize. Performance is more variable and may
depend on the micrarchitecture details, but initial results look good.
If we need to control this per-cpu, we can add a subtarget feature as we
need it.

Original patch by David Penry.

Subject: [PATCH 465/771] [clangd] Always retrieve ProjectInfo from Base in
 OverlayCDB

Summary:
Clangd is returning current working directory for overriden commands.
This can cause inconsistencies between:
- header and the main files, as OverlayCDB only contains entries for the main
  files it direct any queries for the headers to the base, creating a
  discrepancy between the two.
- different clangd instances, as the results will be different depending on the
  timing of execution of the query and override of the command. hence clangd
  might see two different project infos for the same file between different
  invocations.
- editors and the way user has invoked it, as current working directory of
  clangd will depend on those, hence even when there's no underlying base CWD
  might change depending on the editor, or the directory user has started the
  editor in.

This patch gets rid of that discrepency by always directing queries to base or
returning llvm::None in absence of it.

For a sample bug see https://reviews.llvm.org/D83099#2154185.

Subject: [PATCH 466/771] Reland "[NFCI] createCFGSimplificationPass(): migrate
 to also take SimplifyCFGOptions"

This reverts commit 1067d3e176ea7b0b1942c163bf8c6c90107768c1,
which reverted commit b2018198c32a0535bb1f5bb5b40fbcf50d8d47b7,
because it introduced a Dependency Cycle between Transforms/Scalar and
Transforms/Utils.

So let's just move SimplifyCFGOptions.h into Utils/, thus avoiding
the cycle.

 multi-parameter ctor, use default member-init"

This reverts commit 5831e86190966d58385678eb74b26aefacbfd101,
which reverted commit 90c1b0442a031d6cad686fdc4e5d3db03c3603a6
in preparation for reverting
commit b2018198c32a0535bb1f5bb5b40fbcf50d8d47b7 in
commit 1067d3e176ea7b0b1942c163bf8c6c90107768c1 due to the introducton
of a dependency cycle.

Now that the other revert is reverted with a fix, this can be relanded.

Subject: [PATCH 474/771] [SVE] Add lowering for scalable vector fadd, fdiv,
 fmul and fsub operations.

Lower the operations to predicated variants.  This is prep work
required for fixed length code generation but also fixes a bug
whereby these operations fail selection when "unpacked" vector
types (e.g. MVT::nxv2f32) are used.

This patch also adds the missing "unpacked" patterns for FMA.

Subject: [PATCH 480/771] [MLIR] Lower `shape.reduce` to `scf.for` only when
 argument is `tensor<?xindex>`

To make it clear when shape error values cannot occur the shape operations can
operate on extent tensors. This change updates the lowering for `shape.reduce`
accordingly.

Subject: [PATCH 482/771] Remove
 TwoAddressInstructionPass::sink3AddrInstruction.

This function has a bug which will incorrectly reschedule instructions
after an INLINEASM_BR (which can branch). (The bug may also allow
scheduling past a throwing-CALL, I'm not certain.)

I could fix that bug, but, as the removed FIXME notes, it's better to
attempt rescheduling before converting to 3-addr form, as that may
remove the need to convert in the first place. In fact, the code to do
such reordering was added to this pass only a few months later, in
2011, via the addition of the function rescheduleMIBelowKill. That
code does not contain the same bug.

The removal of the sink3AddrInstruction function is not a no-op: in
some cases it would move an instruction post-conversion, when
rescheduleMIBelowKill would not move the instruction pre-converison.
However, this does not appear to be important: the machine instruction
scheduler can reorder the after-conversion instructions, in any case.

This patch fixes a kernel panic 4.4 LTS x86_64 Linux kernels, when

From 569868f6b7f390bb6ceffb4fceb70ff0019c5bea Mon Sep 17 00:00:00 2001
From: Florian Hahn <flo@fhahn.com>
Date: Thu, 16 Jul 2020 12:08:54 +0100
Subject: [PATCH 483/771] [SCCP] Only track returns of functions with non-void
 ret ty (NFC).

There is no need to add functions with void return types to the set of
tracked return values. This does not change functionality, because we
such functions do not have return values and we never update or access

Subject: [PATCH 486/771] [TSan] Optimize handling of racy address

This patch splits the handling of racy address and racy stack into separate
functions. If a race was already reported for the address, we can avoid the
cost for collecting the involved stacks.

This patch also removes the race condition in storing the racy address / racy
stack. This race condition allowed all threads to report the race.

This patch changes the transitive suppression of reports. Previously
suppression could transitively chain memory location and racy stacks.
Now racy memory and racy stack are separate suppressions.

Commit again, now with fixed tests.

Subject: [PATCH 492/771] [AIX]Generate debug info for static init related
 functions

Set the debug location for static init related functions(__dtor
and __finalize) so we can generate valid debug info on AIX by invoking
-g with clang or -debug-info-kind=limited with clang_cc1.

This also works for any other future targets who may use sinit and
sterm functions for static initialization, where a direct call to
dtor will be generated within finalize function body.

This patch also aims at validating that the debug info generated
is correct for AIX sinit related functions.

Subject: [PATCH 495/771] [CMake] Enforce the minimum CMake version to be at
 least 3.13.4

This commit changes the warning for CMake < 3.13.4 into a fatal error.
The intent is to revert and re-apply this simple commit until all build
bots are migrated to CMake >= 3.13.4.

This is part of the effort discussed on llvm-dev here:

Subject: [PATCH 500/771]     [llvm-exegesis] Add benchmark latency option on
 X86 that uses LBR for more precise measurements.

    Starting with Skylake, the LBR contains the precise number of cycles between the two
    consecutive branches.
    Making use of this will hopefully make the measurements more precise than the
    existing methods of using RDTSC.

- to specify at least one of the `-analysis-clusters-output-file=` and
- `-analysis-inconsistencies-output-file=`.
+ Specify the run mode. Note that some modes have additional requirements and options.
 
+ `latency` mode can be  make use of either RDTSC or LBR.
+ `latency[LBR]` is only available on X86 (at least `Skylake`).
+  To run in this mode, a positive value  must be specified for `x86-lbr-sample-period` and `--repetition-mode=loop`
+
+ In `analysis` mode, you also need to specify at least one of the
+ `-analysis-clusters-output-file=` and `-analysis-inconsistencies-output-file=`.
+
+.. option:: -x86-lbr-sample-period=<nBranches/sample>
+
+  Specify the LBR sampling period - how many branches before we take a sample.
+  When a positive value is specified for this option and when the mode is `latency`,
+  we will use LBRs for measuring.
+  On choosing the "right" sampling period, a small value is preferred, but throttling
+  could occur if the sampling is too frequent. A prime number should be used to
+  avoid consistently skipping certain blocks.
+  
 .. option:: -repetition-mode=[duplicate|loop|min]
 
  Specify the repetition mode. `duplicate` will create a large, straight line

Subject: [PATCH 502/771] [BasicAA] Fix -basicaa-recphi for geps with negative
 offsets

As shown in D82998, the basic-aa-recphi option can cause miscompiles for
gep's with negative constants. The option checks for recursive phi, that
recurse through a contant gep. If it finds one, it performs aliasing
calculations using the other phi operands with an unknown size, to
specify that an unknown number of elements after the initial value are
potentially accessed. This works fine expect where the constant is
negative, as the size is still considered to be positive. So this patch
expands the check to make sure that the constant is also positive.

I am changing tests for AST Matchers to run in multiple language standards
versions, and under multiple triples that have different behavior with regards
to templates. This change is similar to https://reviews.llvm.org/D82179.

To keep the size of the patch manageable, in this patch I'm only migrating one
file to get the process started and get feedback on this approach.

Subject: [PATCH 507/771] [scudo][standalone] Release smaller blocks less often

Summary:
Releasing smaller blocks is costly and only yields significant
results when there is a large percentage of free bytes for a given
size class (see numbers below).

This CL introduces a couple of additional checks for sizes lower
than 256. First we want to make sure that there is enough free bytes,
relatively to the amount of allocated bytes. We are looking at 8X% to
9X% (smaller blocks require higher percentage). We also want to make
sure there has been enough activity with the freelist to make it
worth the time, so we now check that the bytes pushed to the freelist
is at least 1/16th of the allocated bytes for those classes.

Additionally, we clear batches before destroying them now - this
could have prevented some releases to occur (class id 0 rarely
releases anyway).

Here are the numbers, for about 1M allocations in multiple threads:

Subject: [PATCH 512/771] AMDGPU: Rename add/sub with carry out instructions

The hardware has created a real mess in the naming for add/sub, which
have been renamed basically every generation. Switch the carry out
pseudos to have the gfx9/gfx10 names. We were using the original SI/CI
v_add_i32/v_sub_i32 names. Later targets reintroduced these names as
carryless instructions with a saturating clamp bit, which we do not
define. Do this rename so we can unambiguously add these missing
instructions.

The carry-in versions should also be renamed, but at least those had a
consistent _u32 name to begin with. The 16-bit instructions were also
renamed, but aren't ambiguous.

This does regress assembler error message quality in some cases. In
mismatched wave32/wave64 situations, this will switch from
"unsupported instruction" to "invalid operand", with the error
pointing at the wrong position. I couldn't quite follow how the
assembler selects these, but the previous behavior seemed accidental
to me. It looked like there was a partial attempt to handle this which
was never completed (i.e. there is an AMDGPUOperand::isBoolReg but it
isn't used for anything).

Subject: [PATCH 514/771] AMDGPU: Rename gfx9 version of v_add_i32/v_sub_i32

The carry-out opcode is renamed, so eliminate the deceptive _gfx9,
which looked like the encoded instruction. The real encoded version
was named _gfx9_gfx9.

Move it into the VI encoding namespace. The gfx9 namespace is just to
deal with the renamed instructions that reinterpret the opcode. When
codegened, it would fail to find the real instruction since it wasn't
in the right namespace.

Subject: [PATCH 515/771] [lldb/ObjectFileMachO] Fetch shared cache images from
 our own shared cache

Summary:
On macOS 11, the libraries that have been integrated in the system
shared cache are not present on the filesystem anymore. LLDB was
using those files to get access to the symbols of those libraries.
LLDB can get the images from the target process memory though.

This has 2 consequences:
 - LLDB cannot load the images before the process starts, reporting
   an error if someone tries to break on a system symbol.
 - Loading the symbols by downloading the data from the inferior
   is super slow. It takes tens of seconds at the start of the
   debug session to populate the Module list.

To fix this, we can use the library images LLDB has in its own
mapping of the shared cache. Shared cache images are somewhat
special as their LINKEDIT segment is moved to the end of the cache
and thus the images are not contiguous in memory. All of this can
hidden in ObjectFileMachO.

This patch fixes a number of test failures on macOS 11 due to the
first problem described above and adds some specific unittesting
for the new SharedCache Host utilities.

Subject: [PATCH 517/771] [Darwin] Fix OS version checks inside simulators

compiler-rt checks OS versions by querying the Darwin kernel version.
This is not necessarily correct inside the simulators if the simulator
runtime is not aligned with the host macOS.  Let's instead check the
`SIMULATOR_RUNTIME_VERSION` env var.

Note that we still use the old code path as a fallback in case the
`SIMULATOR_RUNTIME_VERSION` environment variable isn't set.

Subject: [PATCH 518/771] ValueTracking: Fix isKnownNonZero for non-0 null
 pointers for byval

The IR doesn't have a proper concept of invalid pointers, and "null"
constants are just all zeros (though it really needs one).

I think it's not possible to break this for AMDGPU due to the copy
semantics of byval. If you have an original stack object at 0, the
byval copy will be placed above it so I don't think it's really
possible to hit a 0 address.

Subject: [PATCH 519/771] IR: Rename Argument::hasPassPointeeByValueAttr to
 prepare for byref

When the byref attribute is added, there will need to be two similar
functions for the existing cases which have an associate value copy,
and byref which does not. Most, but not all of the existing uses will
use the existing version.

The associated size function added by D82679 also needs to
contextually differ, and will help eliminate a few places still
relying on pointee element types.

Subject: [PATCH 521/771] MIR Statepoint refactoring. Part 1: Basic MI level
 changes.

Basic support for variadic-def MIR Statepoint:
- Change TableGen STATEPOINT description to variadic out list
  (For self-documentation purpose; by itself it does not affect
  code generation in any way).
- Update StatepointOpers helper class to handle variadic defs.
- Update MachineVerifier to properly handle them, too.

With this change, new Statepoint instruction can be passed through
backend (excluding ISEL) without errors.

Full change set is available at D81603.

Subject: [PATCH 523/771] DAG: Try scalarizing when expanding saturating
 add/sub

In an upcoming AMDGPU patch, the scalar cases will be legal and vector
ops should be scalarized, rather than producing a long sequence of
vector ops which will also need to be scalarized.

Use a lazy heuristic that seems to work and improves the thumb2 MVE
test.

Subject: [PATCH 525/771] [WebAssembly] Lower vselect to v128.bitselect

We were previously expanding vselect and matching on the expansion to
generate bitselects, but in some cases the expansion would be further
combined and a bitselect would not get generated. This patch improves
codegen in those cases by legalizing vselect and lowering it to
v128.bitselect. The old pattern that matches the expansion is still
useful for lowering IR that already uses the expansion rather than a
select operation.

Subject: [PATCH 526/771] [WebAssembly] Autogenerate tests for simd-select.ll

Updating the simd-select.ll tests manually with consistent named
regexps for the register numbers was taking more time than it was
worth, so this patch updates that test file to have autogenerated
output. This is not a significant readability regression because the
tests in that file are all very small.

Depends on D83734.

Subject: [PATCH 527/771] [SCEV] Fix ScalarEvolution tests under NPM

Many tests use opt's -analyze feature, which does not translate well to
NPM and has better alternatives. The alternative here is to explicitly
add a pass that calls ScalarEvolution::print().

The legacy pass manager RUNs aren't changing, but they are now pinned to
the legacy pass manager.  For each legacy pass manager RUN, I added a
corresponding NPM RUN using the 'print<scalar-evolution>' pass. For
compatibility with update_analyze_test_checks.py and existing test
CHECKs, 'print<scalar-evolution>' now prints what -analyze prints per
function.

This was generated by the following Python script and failures were
manually fixed up:

import sys
for i in sys.argv:
    with open(i, 'r') as f:
        s = f.read()
    with open(i, 'w') as f:
        for l in s.splitlines():
            if "RUN:" in l and ' -analyze ' in l and '\\' not in l:
                f.write(l.replace(' -analyze ', ' -analyze -enable-new-pm=0 '))
                f.write('\n')
                f.write(l.replace(' -analyze ', ' -disable-output ').replace(' -scalar-evolution ', ' "-passes=print<scalar-evolution>" ').replace(" | ", " 2>&1 | "))
                f.write('\n')
            else:
                f.write(l)

There are a couple failures still in ScalarEvolution under NPM, but
those are due to other unrelated naming conflicts.

Subject: [PATCH 529/771] AMDGPU: Move handling of AGPR copies to a separate
 function

This is in preparation for fixing multiple problems with the way AGPR
copies are handled, but this change is NFC itself. First, it's relying
on recursively calling copyPhysReg, which is losing information
necessary to get correct super register handling.

Second, it's constructing a new RegScavenger and doing a O(N^2) walk
on every single sub-spill for every AGPR tuple copy. Third, it's using
the forward form of the scavenger, and not using the preferred
backwards scan.

Subject: [PATCH 530/771] [TableGen] Change std::vector to SmallVector

The size of VTList that is pushed into this container is usually 1, but
often 6 or 7. Change the vector to SmallVector to eliminate frequent
mallocs.  This happens hundreds of thousands of times in each tablegen
execution during the LLVM/clang build.

Subject: [PATCH 531/771] [WebAssembly] Implement v128.select

Although the SIMD spec proposal does not specifically include a
select instruction, the select instruction in MVP WebAssembly is
polymorphic over the selected types, so it is able to work on v128
values when they are enabled. This patch introduces a new variant of
the select instruction for each legal vector type. Additional ISel
patterns are adapted from the SELECT_I32 and SELECT_I64 patterns.

Depends on D83736.

Subject: [PATCH 532/771] [LiveVariables] Replace std::vector with SmallVector.

Replace std::vector with SmallVector to reduce the number of mallocs.
This method is frequently executed, and the number of elements in the
vector is typically small.

Subject: [PATCH 533/771] [RISCV] Add support for -mcpu option.

Summary:
1. gcc uses `-march` and `-mtune` flag to chose arch and
pipeline model, but clang does not have `-mtune` flag,
we uses `-mcpu` to chose both infos.
2. Add SiFive e31 and u54 cpu which have default march
and pipeline model.
3. Specific `-mcpu` with rocket-rv[32|64] would select
pipeline model only, and use the driver's arch choosing
logic to get default arch.

Subject: [PATCH 534/771] [compiler-rt][asan][hwasan] Refactor shadow setup
 into sanitizer_common (NFCI)

Summary:
This refactors some common support related to shadow memory setup from
asan and hwasan into sanitizer_common. This should not only reduce code
duplication but also make these facilities available for new compiler-rt
uses (e.g. heap profiling).

In most cases the separate copies of the code were either identical, or
at least functionally identical. A few notes:

In ProtectGap, the asan version checked the address against an upper
bound (kZeroBaseMaxShadowStart, which is (2^18). I have created a copy
of kZeroBaseMaxShadowStart in hwasan_mapping.h, with the same value, as
it isn't clear why that code should not do the same check. If it
shouldn't, I can remove this and guard this check so that it only
happens for asan.

In asan's InitializeShadowMemory, in the dynamic shadow case it was
setting __asan_shadow_memory_dynamic_address to 0 (which then sets both
macro SHADOW_OFFSET as well as macro kLowShadowBeg to 0) before calling
FindDynamicShadowStart(). AFAICT this is only needed because
FindDynamicShadowStart utilizes kHighShadowEnd to
get the shadow size, and kHighShadowEnd is a macro invoking
MEM_TO_SHADOW(kHighMemEnd) which in turn invokes:
(((kHighMemEnd) >> SHADOW_SCALE) + (SHADOW_OFFSET))
I.e. it computes the shadow space needed by kHighMemEnd (the shift), and
adds the offset. Since we only want the shadow space here, the earlier
setting of SHADOW_OFFSET to 0 via __asan_shadow_memory_dynamic_address
accomplishes this. In the hwasan version, it simply gets the shadow
space via "MemToShadowSize(kHighMemEnd)", where MemToShadowSize just
does the shift. I've simplified the asan handling to do the same
thing, and therefore was able to remove the setting of the SHADOW_OFFSET
via __asan_shadow_memory_dynamic_address to 0.

Subject: [PATCH 536/771] [Analyzer] Hotfix for various crashes in iterator
 checkers

The patch that introduces handling iterators implemented as pointers may
cause crash in some projects because pointer difference is mistakenly
handled as pointer decrement. (Similair case for iterators implemented
as class instances are already handled correctly.) This patch fixes this
issue.

The second case that causes crash is comparison of an iterator
implemented as pointer and a null-pointer. This patch contains a fix for
this issue as well.

The third case which causes crash is that the checker mistakenly
considers all integers as nonloc::ConcreteInt when handling an increment
or decrement of an iterator implemented as pointers. This patch adds a
fix for this too.

The last case where crashes were detected is when checking for success
of an std::advance() operation. Since the modeling of iterators
implemented as pointers is still incomplete this may result in an
assertion. This patch replaces the assertion with an early exit and
adds a FIXME there.

Subject: [PATCH 538/771] Temporarily Revert "[AssumeBundles] Use operand
 bundles to encode alignment assumptions" due to the performance bugs filed in
 https://bugs.llvm.org/show_bug.cgi?id=46753.

An SROA change soon may obviate some of these problems.

This reverts commit 8d09f20798ac180b1749276bff364682ce0196ab.

Subject: [PATCH 546/771] [libc++] Remove shortcut Lit features for Apple
 backdeployment

Some time ago, I introduced shortcut features like dylib-has-no-shared_mutex
to encode whether the deployment target supported shared_mutex (say). This
made the test suite annotations cleaner.

However, the problem with building Lit features on top of other Lit
features is that it's easier for them to become stale, especially when
they are generated programmatically. Furthermore, it makes the bar for
defining configurations from scratch higher, since more features have
to be defined. Instead, I think it's better to put the XFAILs in the
tests directly, which allows cleaning them up with a simple grep.

Subject: [PATCH 547/771] [libc++abi] Temporarily disable test on Apple to fix
 the CI

This test has been failing on some SDKs for a long time because we lack
a proper way of identifying the SDK version in Lit. Until that is possible,
mark the test as unsupported on Apple to restore the CI.

Subject: [PATCH 549/771] [X86] Change the tuning settings for pentium4 to be
 more modern since its the default 32-bit cpu in clang

Alternative to D83897. I believe the big change here is that I removed slow unaligned memory 16

Down side that it may adversely effect tuning if someone explicitly targets -march=pentium4 and expects pentium4 tuned code. Of course pentium4 is so old our default behavior with the previous settings may not have been the best either.

Subject: [PATCH 554/771] [libFuzzer] Link libFuzzer's own interceptors when
 other compiler runtimes are not linked.

Summary: libFuzzer intercepts certain library functions such as memcmp/strcmp by defining weak hooks. Weak hooks, however, are called only when other runtimes such as ASan is linked. This patch defines libFuzzer's own interceptors, which is linked into the libFuzzer executable when other runtimes are not linked, i.e., when -fsanitize=fuzzer is given, but not others.

Subject: [PATCH 555/771] [X86] Move integer hadd/hsub formation into a helper
 function shared by combineAdd and combineSub.

There was a lot of duplicate code here for checking the VT and
subtarget. Moving it into a helper avoids that.

It also fixes a bug that combineAdd reused Op0/Op1 after a call
to isHorizontalBinOp may have changed it. The new helper function
has its own local version of Op0/Op1 that aren't shared by other
code.

Fixes PR46455.

Subject: [PATCH 556/771] [NFC][PhaseOrdering] Add a test demonstrating
 pitfails of common code hoisting on loop rotation

Depending on the -rotation-max-header-size=?,
hoisting common code early makes loop rotation impossible.

+;   void f0();
+;   void f1();

+;
+;   void loop(int width) {

+;       f0();
+;       f2();
+;   }
+
+; We have a choice here. We can either
+; * hoist the f0() call into loop header,
+;   * which potentially makes loop rotation unprofitable since loop header might
+;     have grown above certain threshold, and such unrotated loops will be
+;     ignored by LoopVectorizer, preventing vectorization
+;   * or loop rotation will succeed, resulting in some weird PHIs that will also
+;     harm vectorization
+; * or not hoist f0() call before performing loop rotation,
+;   at the cost of potential code bloat and/or potentially successfully rotating
+;   the loops, vectorizing them at the cost of compile time.

Date: Fri, 10 Jul 2020 16:51:01 -0700
Subject: [PATCH 557/771] [WebAssembly] 64-bit (function) pointer fixes.

Accounting for the fact that Wasm function indices are 32-bit, but in wasm64 we want uniform 64-bit pointers.
Includes reloc types for 64-bit table indices.

Subject: [PATCH 559/771] [SimplifyCFG] Fix crash in the EXPENSIVE_CHECKS build

SimplifyCFG was incorrectly reporting to the pass manager that it had not made
changes after folding away a PHI.  This is detected in the EXPENSIVE_CHECKS
build when the function's hash changes.

Subject: [PATCH 561/771] [ORC] Add TargetProcessControl and
 TPCIndirectionUtils APIs.

TargetProcessControl is a new API for communicating with JIT target processes.
It supports memory allocation and access, and inspection of some process
properties, e.g. the target proces triple and page size.

Centralizing these APIs allows utilities written against TargetProcessControl
to remain independent of the communication procotol with the target process
(which may be direct memory access/allocation for in-process JITing, or may
involve some form of IPC or RPC).

An initial set of TargetProcessControl-based utilities for lazy compilation is
provided by the TPCIndirectionUtils class.

An initial implementation of TargetProcessControl for in-process JITing
is provided by the SelfTargetProcessControl class.

An example program showing how the APIs can be used is provided in
llvm/examples/OrcV2Examples/LLJITWithTargetProcessControl.

Subject: [PATCH 562/771] [compiler-rt][asan][hwasan] Fix Android bots

Fix failure in Android bots from refactoring in
5d2be1a18845c528d3e86f7efcc59872e4a757c3 (https://crbug.com/1106482).

We need to make the UnmapFromTo available outside sanitizer_common for
calls from hwasan and asan linux handling. While here, remove
declaration of GetHighMemEnd which is no longer in sanitizer_common.

Subject: [PATCH 563/771] [builtins] Omit 80-bit builtins on Android and MSVC

long double is a 64-bit double-precision type on:
 - MSVC (32- and 64-bit x86)
 - Android (32-bit x86)

long double is a 128-bit quad-precision type on x86_64 Android.

The assembly variants of the 80-bit builtins are correct, but some of
the builtins are implemented in C and require that long double be the
80-bit type passed via an x87 register.

Subject: [PATCH 569/771] [libFuzzer] Disable implicit builtin knowledge about
 memcmp-like functions when -fsanitize=fuzzer-no-link is given.

Summary: This patch disables implicit builtin knowledge about memcmp-like functions when compiling the program for fuzzing, i.e., when -fsanitize=fuzzer(-no-link) is given. This allows libFuzzer to always intercept memcmp-like functions as it effectively disables optimizing calls to such functions into different forms. This is done by adding a set of flags (-fno-builtin-memcmp and others) in the clang driver. Individual -fno-builtin-* flags previously used in several libFuzzer tests are now removed, as it is now done automatically in the clang driver.

Subject: [PATCH 572/771] [profile] Move __llvm_profile_raw_version into a
 separate file

Similar to the reason behind moving __llvm_profile_filename into a
separate file[1]. When users try to use Full LTO with BFD linker to
generate IR level PGO profile, the __llvm_profile_raw_version variable,
which is used for marking instrumentation level, generated by frontend
would somehow conflict with the weak symbol provided by profiling
runtime.

In most of the cases, BFD linkers will pick profiling runtime's weak symbol
as the real definition and thus generate the incorrect instrumentation
level metadata in the final executables.

Moving __llvm_profile_raw_version into a separate file would make
linkers not seeing the weak symbol in the archive unless the frontend
doesn't generate one.

Subject: [PATCH 577/771] Revert "[libFuzzer] Link libFuzzer's own interceptors
 when other compiler runtimes are not linked."

This causes binaries linked with this runtime to crash on startup if
dlsym uses any of the intercepted functions. (For example, that happens
when using tcmalloc as the allocator: dlsym attempts to allocate memory
with malloc, and tcmalloc uses strncmp within its implementation.)

Also revert dependent commit "[libFuzzer] Disable implicit builtin knowledge about memcmp-like functions when -fsanitize=fuzzer-no-link is given."

This reverts commit f78d9fceea736d431e9e3cbca291e3909e3aa46d and 12d1124c49beec0fb79d36944960e5bf0f236d4c.

Subject: [PATCH 581/771] [LangRef] Mention that freeze does not consider
 aggregate's paddings

Make explicit that freeze does not touch paddings of an aggregate.
(Relevant comment: https://reviews.llvm.org/D83752#2152550)

This implies that `v = freeze(load p); store v, q` may still leave undef bits
or poison in memory if `v` is an aggregate, but it still happens for
non-byte integers such as i1.

 :ref:`Pointer Aliasing Rules <pointeraliasing>` section for more information.
+If an aggregate value or vector is frozen, the operand is frozen element-wise.
+The padding of an aggregate isn't considered, since it isn't visible
+without storing it into memory and loading it with a different type.

Subject: [PATCH 588/771] [X86] Reorder how the subtarget map key is created.

We use a SmallString<512> and attempted to reserve enough space
for CPU plus Features, but that doesn't account for all the things
that get added to the string.

Reorder the string so the shortest things go first which shouldn't
exceed the small size. Finally add the feature string at the end
which might be long. This should ensure at most one heap allocation
without needing to use reserve.

I don't know if this matters much in practice, but I was looking
into something else that will require more code here and noticed
the odd reserve call.

Subject: [PATCH 589/771] [X86] Change the scheduler model for 'pentium4' to
 SandyBridgeModel.

I meant to do this in D83913, but missed it while updating the
feature list.

Interestingly I think this is disabling the postRA scheduler. But
it does match our default 64-bit behavior.

Subject: [PATCH 590/771] [lldb] Only set the executable module for a target
 once

Summary:

When we try to find the executable module for our target we don't check
if we already have an executable module set. This causes that when debugging
a program that dlopens another executable, LLDB will take that other executable
as the new executable of the target (which causes that future launches of the
target will launch the dlopen'd executable instead of the original executable).

This just adds a check that we only set the executable when we haven't already
found one.

Fixes rdar://63443099

Subject: [PATCH 591/771] [DebugInfo] Fix a misleading usage of DWARF forms
 with DIEExpr. NFCI.

For now, DIEExpr is used only in two places:

 1) in the debug info library unit test suite to emit
    a DW_AT_str_offsets_base attribute with the DW_FORM_sec_offset
    form, see dwarfgen::DIE::addStrOffsetsBaseAttribute();

 2) in DwarfCompileUnit::addLocationAttribute() to generate the location
    attribute for a TLS variable.

The later case used an incorrect DWARF form of DW_FORM_udata, which
implies storing an uleb128 value, not a 4/8 byte constant. The generated
result was as expected because DIEExpr::SizeOf() did not handle the used
form, but returned the size of the code pointer by default.

The patch fixes the issue by using more appropriate DWARF forms for
the problematic case and making DIEExpr::SizeOf() more straightforward.

Subject: [PATCH 593/771] [InstCombine] Fix replace select with Phis when
 branch has the same labels

```
define i32 @test(i1 %cond) {
entry:
  br i1 %cond, label %exit, label %exit
exit:
  %result = select i1 %cond, i32 123, i32 456
  ret i32 %result
}
```
In this test, after applying transformation of replacing select with Phis,
the result will be:

```
define i32 @test(i1 %cond) {
entry:
  br i1 %cond, label %exit, label %exit
exit:
  %result = i32 phi [123, %exit], [123, %exit]
  ret i32 %result
}
```
That is, select is transformed into an invalid Phi, which will then be
reduced to 123 and the second value will be lost. But it is worth
noting that this problem will arise only if select is in the InstCombine
worklist will be before the branch. Otherwise, InstCombine will replace
the branch condition with false and transformation will not be applied.

The fix is to check the target labels in the branch condition for equality.

Subject: [PATCH 597/771] [lldb] Store StackFrameRecognizers in the target
 instead of a global list

Summary:

Currently the frame recognizers are stored in a global list (the list in the
StackFrameRecognizersManagerImpl singleton to be precise). All commands and
plugins that modify the list are just modifying that global list of recognizers
which is shared by all Target and Debugger instances.

This is clearly against the idea of LLDB being usable as a library and it also
leads to some very obscure errors as now multiple tests are sharing the used
frame recognizers. For example D83400 is currently failing as it reorders some
test_ functions which permanently changes the frame recognizers of all
debuggers/targets. As all frame recognizers are also initialized in a 'once'
guard, it's also impossible to every restore back the original frame recognizers
once they are deleted in a process.

This patch just moves the frame recognizers into the current target. This seems
the way everyone assumes the system works as for example the assert frame
recognizers is using the current target to find the function/so-name to look for
(which only works if the recognizers are stored in the target).

Subject: [PATCH 600/771] [TSan] Add option for emitting compound read-write
 instrumentation

This adds option -tsan-compound-read-before-write to emit different
instrumentation for the write if the read before that write is omitted
from instrumentation. The default TSan runtime currently does not
support the different instrumentation, and the option is disabled by
default.

Alternative runtimes, such as the Kernel Concurrency Sanitizer (KCSAN)
can make use of the feature. Indeed, the initial motivation is for use
in KCSAN as it was determined that due to the Linux kernel having a
large number of unaddressed data races, it makes sense to improve
performance and reporting by distinguishing compounded operations. E.g.
the compounded instrumentation is typically emitted for compound
operations such as ++, +=, |=, etc. By emitting different reports, such
data races can easily be noticed, and also automatically bucketed
differently by CI systems.

Subject: [PATCH 606/771] [ScheduleDAG] Move DBG_VALUEs after first term
 forward.

MBBs are not allowed to have non-terminator instructions after the first
terminator. Currently in some cases (see the modified test),
EmitSchedule can add DBG_VALUEs after the last terminator, for example
when referring a debug value that gets folded into a TCRETURN
instruction on ARM.

This patch updates EmitSchedule to move inserted DBG_VALUEs just before
the first terminator. I am not sure if there are terminators produce
values that can in turn be used by a DBG_VALUE. In that case, moving the
DBG_VALUE might result in referencing an undefined register. But in any
case, it seems like currently there is no way to insert a proper DBG_VALUEs
for such registers anyways.

Alternatively it might make sense to just remove those extra DBG_VALUES.

I am not too familiar with the details of debug info in the backend and
would appreciate any suggestions on how to address the issue in the best
possible way.

Subject: [PATCH 608/771] [lldb/DWARF] Don't get confused by line sequences
 with tombstone values

Summary:
With D81784, lld has started debug info resolving relocations to
garbage-collected symbols as -1 (instead of relocation addend). For an
unaware consumer this generated sequences which seemingly wrap the
address space -- their first entry was 0xfffff, but all other entries
were low numbers.

Lldb stores line sequences concatenated into one large vector, sorted by
the first entry, and searched with std::lower_bound. This resulted in
the low-value entries being placed at the end of the vector, which
utterly confused the lower_bound algorithm, and caused it to not find a
match. (Previously, these sequences would be at the start of the vector,
and normally would contain addresses that are far smaller than any real
address we want to look up, so std::lower_bound was fine.)

This patch makes lldb ignore these kinds of sequences completely. It
does that by changing the construction algorithm from iterating over the
rows (as parsed by llvm), to iterating over the sequences. This is
important because the llvm parsed performs validity checks when
constructing the sequence array, whereas the row array contains raw
data.

Subject: [PATCH 609/771] [MachineScheduler] Fix the TopDepth/BotHeightReduce
 latency heuristics

tryLatency compares two sched candidates. For the top zone it prefers
the one with lesser depth, but only if that depth is greater than the
total latency of the instructions we've already scheduled -- otherwise
its latency would be hidden and there would be no stall.

Unfortunately it only tests the depth of one of the candidates. This can
lead to situations where the TopDepthReduce heuristic does not kick in,
but a lower priority heuristic chooses the other candidate, whose depth
*is* greater than the already scheduled latency, which causes a stall.

The fix is to apply the heuristic if the depth of *either* candidate is
greater than the already scheduled latency.

All this also applies to the BotHeightReduce heuristic in the bottom
zone.

Subject: [PATCH 610/771] [Sema][AArch64] Add parsing support for
 arm_sve_vector_bits attribute

Summary:

This patch implements parsing support for the 'arm_sve_vector_bits' type
attribute, defined by the Arm C Language Extensions (ACLE, version 00bet5,
section 3.7.3) for SVE [1].

The purpose of this attribute is to define fixed-length (VLST) versions
of existing sizeless types (VLAT). For example:

    #if __ARM_FEATURE_SVE_BITS==512
    typedef svint32_t fixed_svint32_t __attribute__((arm_sve_vector_bits(512)));
    #endif

Creates a type 'fixed_svint32_t' that is a fixed-length version of
'svint32_t' that is normal-sized (rather than sizeless) and contains
exactly 512 bits. Unlike 'svint32_t', this type can be used in places
such as structs and arrays where sizeless types can't.

Implemented in this patch is the following:

  * Defined and tested attribute taking single argument.
  * Checks the argument is an integer constant expression.
  * Attribute can only be attached to a single SVE vector or predicate
    type, excluding tuple types such as svint32x4_t.
  * Added the `-msve-vector-bits=<bits>` flag. When specified the
    `__ARM_FEATURE_SVE_BITS__EXPERIMENTAL` macro is defined.
  * Added a language option to store the vector size specified by the
    `-msve-vector-bits=<bits>` flag. This is used to validate `N ==
    __ARM_FEATURE_SVE_BITS`, where N is the number of bits passed to the
    attribute and `__ARM_FEATURE_SVE_BITS` is the feature macro defined under
    the same flag.

The `__ARM_FEATURE_SVE_BITS` macro will be made non-experimental in the final
patch of the series.

+The ``arm_sve_vector_bits(N)`` attribute is defined by the Arm C Language
+Extensions (ACLE) for SVE. It is used to define fixed-length (VLST) variants of
+sizeless types (VLAT).
+
+For example:
+
+.. code-block:: c
+
+  #include <arm_sve.h>
+
+  #if __ARM_FEATURE_SVE_BITS==512
+  typedef svint32_t fixed_svint32_t __attribute__((arm_sve_vector_bits(512)));
+  #endif
+
+Creates a type ``fixed_svint32_t`` that is a fixed-length variant of
+``svint32_t`` that contains exactly 512-bits. Unlike ``svint32_t``, this type
+can be used in globals, structs, unions, and arrays, all of which are
+unsupported for sizeless types.
+
+The attribute can be attached to a single SVE vector (such as ``svint32_t``) or
+to the SVE predicate type ``svbool_t``, this excludes tuple types such as
+``svint32x4_t``. The behavior of the attribute is undefined unless
+``N==__ARM_FEATURE_SVE_BITS``, the implementation defined feature macro that is
+enabled under the ``-msve-vector-bits`` flag.
+
+NOTE: This feature is currently WIP, the ``-msve-vector-bits=`` flag defines
+the ``__ARM_FEATURE_SVE_BITS_EXPERIMENTAL`` macro. This feature is complete
+when experimental is dropped.
+
+For more information See `Arm C Language Extensions for SVE
+<https://developer.arm.com/documentation/100987/latest>`_ for more information.

Subject: [PATCH 611/771] [InstCombine][Test] Test for fix of replacing select
 with Phis when branch has the same labels

An additional test that allows to check the correctness of handling the case of the same
branch labels in the dominator when trying to replace select with phi-node.

Subject: [PATCH 613/771] [AMDGPU] Avoid splitting FLAT offsets in unsafe ways

As explained in the comment:

// For a FLAT instruction the hardware decides whether to access
// global/scratch/shared memory based on the high bits of vaddr,
// ignoring the offset field, so we have to ensure that when we add
// remainder to vaddr it still points into the same underlying object.
// The easiest way to do that is to make sure that we split the offset
// into two pieces that are both >= 0 or both <= 0.

In particular FLAT (as opposed to SCRATCH and GLOBAL) instructions have
an unsigned immediate offset field, so we can't use it to help split a
negative offset.

Subject: [PATCH 614/771] [HWLoops] Stop converting to a while loop when it
 would be unsafe to

There were cases where a do-while loop would be converted to a while
loop before finding out that it would be unsafe to expand the SCEV in
this situation and then bailing out of hardware loop conversion.

This patch checks if it would be unsafe to expand the SCEV and if so stops converting the do-while into a while, allowing conversion to a hardware loop.

Subject: [PATCH 615/771] [lldb/COFF] Remove strtab zeroing hack

Summary:
This code (recently responsible for a unaligned access sanitizer
failure) claims that the string table offset zero should result in an
empty string.

I cannot find any mention of this detail in the Microsoft COFF
documentation, and the llvm COFF parser also does not handle offset zero
specially. This code was introduced in 0076e7159, which also does not go
into specifics, citing "various bugfixes".

Given that this is obviously a hack, and does not cause tests to fail, I
think we should just delete it.

Subject: [PATCH 618/771] [CUDA][HIP] Always defer diagnostics for wrong-sided
 reference

When a device function calls a host function or vice versa, this is wrong-sided
reference. Currently clang immediately diagnose it. This is different from nvcc
behavior, where it is diagnosed only if the function is really emitted.

Current clang behavior causes false alarms for valid use cases.

This patch let clang always defer diagnostics for wrong-sided
reference.

Subject: [PATCH 624/771] [llvm-readobj] - Add proper testing for the
 SHT_MIPS_ABIFLAGS section.

This rewrites the mips-abiflags.test to stop using recompiled objects,
adds testing for all missed bits and also adds two missing enum values
to lib/ObjectYAML, which are used in the new test.

Subject: [PATCH 625/771] [LV] Enable the LoopVectorizer to create pointer
 inductions

This patch enables the LoopVectorizer to build a phi of pointer
type and provide the vector loads and stores with vector type
getelementptrs built from the pointer induction variable, which
produces much less instructions than the previous approach of
creating scalar getelementpointers and glue them together to a
vector.

Subject: [PATCH 631/771] [Loop Simplify] Resolve an issue where metadata is
 not applied to a loop latch.

Summary:
This patch resolves an issue where the metadata of a loop is not added to the
new loop latch, and not removed from the old loop latch. This issue occurs in
the SplitBlockPredecessors function, which  adds a new block in a loop, and
in the case that the block passed into this function is the header of the loop,
the loop can be modified such that the latch of the loop is replaced.
This patch applies to the Loop Simplify pass since it ensures that each loop
has exit blocks which only have predecessors that are inside of the loop. In
the case that this is not true, the pass will create a new exit block for the
loop. This guarantees that the loop preheader/header will dominate the exit blocks.

Subject: [PATCH 634/771] [OpenMP][NFC] Generalize CGOpenMPRuntimeNVPTX as
 CGOpenMPRuntimeGPU

Refactors CGOpenMPRuntimeNVPTX as CGOpenMPRuntimeGPU to make it a
generalization for OpenMP GPU Codegen. Target specific specialized
methods for NVPTX are defined in class CGOpenMPRuntimeNVPTX. This
paves the way for a clean and maintainable extension to more GPU
targets for OpenMP Codegen.

For original author (git blame) list of CGOpenMPRuntimeGPU code,
look in history of CGOpenMPRuntimeNVPTX.cpp and .h, after this commit.

+/// Full Warp Reduce (argument value 0):
+///   This algorithm assumes that all 32 lanes are active and gathers
+///   data from these 32 lanes, producing a single resultant value.
+/// Contiguous Partial Warp Reduce (argument value 1):
+///   This algorithm assumes that only a *contiguous* subset of lanes
+///   are active.  This happens for the last warp in a parallel region
+///   when the user specified num_threads is not an integer multiple of
+///   32.  This contiguous subset always starts with the zeroth lane.
+/// Partial Warp Reduce (argument value 2):
+///   This algorithm gathers data from any number of lanes at any position.
+/// All reduced values are stored in the lowest possible lane.  The set
+/// of problems every algorithm addresses is a super set of those
+/// addressable by algorithms with a lower version number.  Overhead
+/// increases as algorithm version increases.
+///
+/// Terminology
+/// Reduce element:
+///   Reduce element refers to the individual data field with primitive
+///   data types to be combined and reduced across threads.
+/// Reduce list:
+///   Reduce list refers to a collection of local, thread-private
+///   reduce elements.
+/// Remote Reduce list:
+///   Remote Reduce list refers to a collection of remote (relative to
+///   the current thread) reduce elements.
+///
+/// We distinguish between three states of threads that are important to
+/// the implementation of this function.
+/// Alive threads:
+///   Threads in a warp executing the SIMT instruction, as distinguished from
+///   threads that are inactive due to divergent control flow.
+/// Active threads:
+///   The minimal set of threads that has to be alive upon entry to this
+///   function.  The computation is correct iff active threads are alive.
+///   Some threads are alive but they are not active because they do not
+///   contribute to the computation in any useful manner.  Turning them off
+///   may introduce control flow overheads without any tangible benefits.
+/// Effective threads:
+///   In order to comply with the argument requirements of the shuffle
+///   function, we must keep all lanes holding data alive.  But at most
+///   half of them perform value aggregation; we refer to this half of
+///   threads as effective. The other half is simply handing off their
+///   data.
+///
+/// Procedure
+/// Value shuffle:
+///   In this step active threads transfer data from higher lane positions
+///   in the warp to lower lane positions, creating Remote Reduce list.
+/// Value aggregation:
+///   In this step, effective threads combine their thread local Reduce list
+///   with Remote Reduce list and store the result in the thread local
+///   Reduce list.
+/// Value copy:
+///   In this step, we deal with the assumption made by algorithm 2
+///   (i.e. contiguity assumption).  When we have an odd number of lanes
+///   active, say 2k+1, only k threads will be effective and therefore k
+///   new values will be produced.  However, the Reduce list owned by the
+///   (2k+1)th thread is ignored in the value aggregation.  Therefore
+///   we copy the Reduce list from the (2k+1)th lane to (k+1)th lane so
+///   that the contiguity assumption still holds.

+/// Design of OpenMP reductions on the GPU
+///
+/// Consider a typical OpenMP program with one or more reduction
+/// clauses:
+///
+/// float foo;
+/// double bar;
+/// #pragma omp target teams distribute parallel for \
+///             reduction(+:foo) reduction(*:bar)
+/// for (int i = 0; i < N; i++) {
+///   foo += A[i]; bar *= B[i];
+/// }
+///
+/// where 'foo' and 'bar' are reduced across all OpenMP threads in
+/// all teams.  In our OpenMP implementation on the NVPTX device an
+/// OpenMP team is mapped to a CUDA threadblock and OpenMP threads
+/// within a team are mapped to CUDA threads within a threadblock.
+/// Our goal is to efficiently aggregate values across all OpenMP
+/// threads such that:
+///
+///   - the compiler and runtime are logically concise, and
+///   - the reduction is performed efficiently in a hierarchical
+///     manner as follows: within OpenMP threads in the same warp,
+///     across warps in a threadblock, and finally across teams on
+///     the NVPTX device.
+///
+/// Introduction to Decoupling
+///
+/// We would like to decouple the compiler and the runtime so that the
+/// latter is ignorant of the reduction variables (number, data types)
+/// and the reduction operators.  This allows a simpler interface
+/// and implementation while still attaining good performance.
+///
+/// Pseudocode for the aforementioned OpenMP program generated by the
+/// compiler is as follows:
+///
+/// 1. Create private copies of reduction variables on each OpenMP
+///    thread: 'foo_private', 'bar_private'
+/// 2. Each OpenMP thread reduces the chunk of 'A' and 'B' assigned
+///    to it and writes the result in 'foo_private' and 'bar_private'
+///    respectively.
+/// 3. Call the OpenMP runtime on the GPU to reduce within a team
+///    and store the result on the team master:
+///
+///     __kmpc_nvptx_parallel_reduce_nowait_v2(...,
+///        reduceData, shuffleReduceFn, interWarpCpyFn)
+///
+///     where:
+///       struct ReduceData {
+///         double *foo;
+///         double *bar;
+///       } reduceData
+///       reduceData.foo = &foo_private
+///       reduceData.bar = &bar_private
+///
+///     'shuffleReduceFn' and 'interWarpCpyFn' are pointers to two
+///     auxiliary functions generated by the compiler that operate on
+///     variables of type 'ReduceData'.  They aid the runtime perform
+///     algorithmic steps in a data agnostic manner.
+///
+///     'shuffleReduceFn' is a pointer to a function that reduces data
+///     of type 'ReduceData' across two OpenMP threads (lanes) in the
+///     same warp.  It takes the following arguments as input:
+///
+///     a. variable of type 'ReduceData' on the calling lane,
+///     b. its lane_id,
+///     c. an offset relative to the current lane_id to generate a
+///        remote_lane_id.  The remote lane contains the second
+///        variable of type 'ReduceData' that is to be reduced.
+///     d. an algorithm version parameter determining which reduction
+///        algorithm to use.
+///
+///     'shuffleReduceFn' retrieves data from the remote lane using
+///     efficient GPU shuffle intrinsics and reduces, using the
+///     algorithm specified by the 4th parameter, the two operands
+///     element-wise.  The result is written to the first operand.
+///
+///     Different reduction algorithms are implemented in different
+///     runtime functions, all calling 'shuffleReduceFn' to perform
+///     the essential reduction step.  Therefore, based on the 4th
+///     parameter, this function behaves slightly differently to
+///     cooperate with the runtime to ensure correctness under
+///     different circumstances.
+///
+///     'InterWarpCpyFn' is a pointer to a function that transfers
+///     reduced variables across warps.  It tunnels, through CUDA
+///     shared memory, the thread-private data of type 'ReduceData'
+///     from lane 0 of each warp to a lane in the first warp.
+/// 4. Call the OpenMP runtime on the GPU to reduce across teams.
+///    The last team writes the global reduced value to memory.
+///
+///     ret = __kmpc_nvptx_teams_reduce_nowait(...,
+///             reduceData, shuffleReduceFn, interWarpCpyFn,
+///             scratchpadCopyFn, loadAndReduceFn)
+///
+///     'scratchpadCopyFn' is a helper that stores reduced
+///     data from the team master to a scratchpad array in
+///     global memory.
+///
+///     'loadAndReduceFn' is a helper that loads data from
+///     the scratchpad array and reduces it with the input
+///     operand.
+///
+///     These compiler generated functions hide address
+///     calculation and alignment information from the runtime.
+/// 5. if ret == 1:
+///     The team master of the last team stores the reduced
+///     result to the globals in memory.
+///     foo += reduceData.foo; bar *= reduceData.bar
+///
+///
+/// Warp Reduction Algorithms
+///
+/// On the warp level, we have three algorithms implemented in the
+/// OpenMP runtime depending on the number of active lanes:
+///
+/// Full Warp Reduction
+///
+/// The reduce algorithm within a warp where all lanes are active
+/// is implemented in the runtime as follows:
+///
+/// full_warp_reduce(void *reduce_data,
+///                  kmp_ShuffleReductFctPtr ShuffleReduceFn) {
+///   for (int offset = WARPSIZE/2; offset > 0; offset /= 2)
+///     ShuffleReduceFn(reduce_data, 0, offset, 0);
+/// }
+///
+/// The algorithm completes in log(2, WARPSIZE) steps.
+///
+/// 'ShuffleReduceFn' is used here with lane_id set to 0 because it is
+/// not used therefore we save instructions by not retrieving lane_id
+/// from the corresponding special registers.  The 4th parameter, which
+/// represents the version of the algorithm being used, is set to 0 to
+/// signify full warp reduction.
+///
+/// In this version, 'ShuffleReduceFn' behaves, per element, as follows:
+///
+/// #reduce_elem refers to an element in the local lane's data structure
+/// #remote_elem is retrieved from a remote lane
+/// remote_elem = shuffle_down(reduce_elem, offset, WARPSIZE);
+/// reduce_elem = reduce_elem REDUCE_OP remote_elem;
+///
+/// Contiguous Partial Warp Reduction
+///
+/// This reduce algorithm is used within a warp where only the first
+/// 'n' (n <= WARPSIZE) lanes are active.  It is typically used when the
+/// number of OpenMP threads in a parallel region is not a multiple of
+/// WARPSIZE.  The algorithm is implemented in the runtime as follows:
+///
+/// void
+/// contiguous_partial_reduce(void *reduce_data,
+///                           kmp_ShuffleReductFctPtr ShuffleReduceFn,
+///                           int size, int lane_id) {
+///   int curr_size;
+///   int offset;
+///   curr_size = size;
+///   mask = curr_size/2;
+///   while (offset>0) {
+///     ShuffleReduceFn(reduce_data, lane_id, offset, 1);
+///     curr_size = (curr_size+1)/2;
+///     offset = curr_size/2;
+///   }
+/// }
+///
+/// In this version, 'ShuffleReduceFn' behaves, per element, as follows:
+///
+/// remote_elem = shuffle_down(reduce_elem, offset, WARPSIZE);
+/// if (lane_id < offset)
+///     reduce_elem = reduce_elem REDUCE_OP remote_elem
+/// else
+///     reduce_elem = remote_elem
+///
+/// This algorithm assumes that the data to be reduced are located in a
+/// contiguous subset of lanes starting from the first.  When there is
+/// an odd number of active lanes, the data in the last lane is not
+/// aggregated with any other lane's dat but is instead copied over.
+///
+/// Dispersed Partial Warp Reduction
+///
+/// This algorithm is used within a warp when any discontiguous subset of
+/// lanes are active.  It is used to implement the reduction operation
+/// across lanes in an OpenMP simd region or in a nested parallel region.
+///
+/// void
+/// dispersed_partial_reduce(void *reduce_data,
+///                          kmp_ShuffleReductFctPtr ShuffleReduceFn) {
+///   int size, remote_id;
+///   int logical_lane_id = number_of_active_lanes_before_me() * 2;
+///   do {
+///       remote_id = next_active_lane_id_right_after_me();
+///       # the above function returns 0 of no active lane
+///       # is present right after the current lane.
+///       size = number_of_active_lanes_in_this_warp();
+///       logical_lane_id /= 2;
+///       ShuffleReduceFn(reduce_data, logical_lane_id,
+///                       remote_id-1-threadIdx.x, 2);
+///   } while (logical_lane_id % 2 == 0 && size > 1);
+/// }
+///
+/// There is no assumption made about the initial state of the reduction.
+/// Any number of lanes (>=1) could be active at any position.  The reduction
+/// result is returned in the first active lane.
+///
+/// In this version, 'ShuffleReduceFn' behaves, per element, as follows:
+///
+/// remote_elem = shuffle_down(reduce_elem, offset, WARPSIZE);
+/// if (lane_id % 2 == 0 && offset > 0)
+///     reduce_elem = reduce_elem REDUCE_OP remote_elem
+/// else
+///     reduce_elem = remote_elem
+///
+///
+/// Intra-Team Reduction
+///
+/// This function, as implemented in the runtime call
+/// '__kmpc_nvptx_parallel_reduce_nowait_v2', aggregates data across OpenMP
+/// threads in a team.  It first reduces within a warp using the
+/// aforementioned algorithms.  We then proceed to gather all such
+/// reduced values at the first warp.
+///
+/// The runtime makes use of the function 'InterWarpCpyFn', which copies
+/// data from each of the "warp master" (zeroth lane of each warp, where
+/// warp-reduced data is held) to the zeroth warp.  This step reduces (in
+/// a mathematical sense) the problem of reduction across warp masters in
+/// a block to the problem of warp reduction.
+///
+///
+/// Inter-Team Reduction
+///
+/// Once a team has reduced its data to a single value, it is stored in
+/// a global scratchpad array.  Since each team has a distinct slot, this
+/// can be done without locking.
+///
+/// The last team to write to the scratchpad array proceeds to reduce the
+/// scratchpad array.  One or more workers in the last team use the helper
+/// 'loadAndReduceDataFn' to load and reduce values from the array, i.e.,
+/// the k'th worker reduces every k'th element.
+///
+/// Finally, a call is made to '__kmpc_nvptx_parallel_reduce_nowait_v2' to
+/// reduce across workers and compute a globally reduced value.

-/// Alive threads:
-///   Threads in a warp executing the SIMT instruction, as distinguished from
-///   threads that are inactive due to divergent control flow.
-/// Active threads:
-///   The minimal set of threads that has to be alive upon entry to this
-///   function.  The computation is correct iff active threads are alive.
-///   Some threads are alive but they are not active because they do not
-///   contribute to the computation in any useful manner.  Turning them off
-///   may introduce control flow overheads without any tangible benefits.
-/// Effective threads:
-///   In order to comply with the argument requirements of the shuffle
-///   function, we must keep all lanes holding data alive.  But at most
-///   half of them perform value aggregation; we refer to this half of
-///   threads as effective. The other half is simply handing off their
-///   data.
-///
-/// Procedure
-/// Value shuffle:
-///   In this step active threads transfer data from higher lane positions
-///   in the warp to lower lane positions, creating Remote Reduce list.
-/// Value aggregation:
-///   In this step, effective threads combine their thread local Reduce list
-///   with Remote Reduce list and store the result in the thread local
-///   Reduce list.
-/// Value copy:
-///   In this step, we deal with the assumption made by algorithm 2
-///   (i.e. contiguity assumption).  When we have an odd number of lanes
-///   active, say 2k+1, only k threads will be effective and therefore k
-///   new values will be produced.  However, the Reduce list owned by the
-///   (2k+1)th thread is ignored in the value aggregation.  Therefore
-///   we copy the Reduce list from the (2k+1)th lane to (k+1)th lane so
-///   that the contiguity assumption still holds.

-/// Design of OpenMP reductions on the GPU
-///
-/// Consider a typical OpenMP program with one or more reduction
-/// clauses:
-///
-/// float foo;
-/// double bar;
-/// #pragma omp target teams distribute parallel for \
-///             reduction(+:foo) reduction(*:bar)
-/// for (int i = 0; i < N; i++) {
-///   foo += A[i]; bar *= B[i];
-/// }
-///
-/// where 'foo' and 'bar' are reduced across all OpenMP threads in
-/// all teams.  In our OpenMP implementation on the NVPTX device an
-/// OpenMP team is mapped to a CUDA threadblock and OpenMP threads
-/// within a team are mapped to CUDA threads within a threadblock.
-/// Our goal is to efficiently aggregate values across all OpenMP
-/// threads such that:
-///
-///   - the compiler and runtime are logically concise, and
-///   - the reduction is performed efficiently in a hierarchical
-///     manner as follows: within OpenMP threads in the same warp,
-///     across warps in a threadblock, and finally across teams on
-///     the NVPTX device.
-///
-/// Introduction to Decoupling
-///
-/// We would like to decouple the compiler and the runtime so that the
-/// latter is ignorant of the reduction variables (number, data types)
-/// and the reduction operators.  This allows a simpler interface
-/// and implementation while still attaining good performance.
-///
-/// Pseudocode for the aforementioned OpenMP program generated by the
-/// compiler is as follows:
-///
-/// 1. Create private copies of reduction variables on each OpenMP
-///    thread: 'foo_private', 'bar_private'
-/// 2. Each OpenMP thread reduces the chunk of 'A' and 'B' assigned
-///    to it and writes the result in 'foo_private' and 'bar_private'
-///    respectively.
-/// 3. Call the OpenMP runtime on the GPU to reduce within a team
-///    and store the result on the team master:
-///
-///     __kmpc_nvptx_parallel_reduce_nowait_v2(...,
-///        reduceData, shuffleReduceFn, interWarpCpyFn)
-///
-///     where:
-///       struct ReduceData {
-///         double *foo;
-///         double *bar;
-///       } reduceData
-///       reduceData.foo = &foo_private
-///       reduceData.bar = &bar_private
-///
-///     'shuffleReduceFn' and 'interWarpCpyFn' are pointers to two
-///     auxiliary functions generated by the compiler that operate on
-///     variables of type 'ReduceData'.  They aid the runtime perform
-///     algorithmic steps in a data agnostic manner.
-///
-///     'shuffleReduceFn' is a pointer to a function that reduces data
-///     of type 'ReduceData' across two OpenMP threads (lanes) in the
-///     same warp.  It takes the following arguments as input:
-///
-///     a. variable of type 'ReduceData' on the calling lane,
-///     b. its lane_id,
-///     c. an offset relative to the current lane_id to generate a
-///        remote_lane_id.  The remote lane contains the second
-///        variable of type 'ReduceData' that is to be reduced.
-///     d. an algorithm version parameter determining which reduction
-///        algorithm to use.
-///
-///     'shuffleReduceFn' retrieves data from the remote lane using
-///     efficient GPU shuffle intrinsics and reduces, using the
-///     algorithm specified by the 4th parameter, the two operands
-///     element-wise.  The result is written to the first operand.
-///
-///     Different reduction algorithms are implemented in different
-///     runtime functions, all calling 'shuffleReduceFn' to perform
-///     the essential reduction step.  Therefore, based on the 4th
-///     parameter, this function behaves slightly differently to
-///     cooperate with the runtime to ensure correctness under
-///     different circumstances.
-///
-///     'InterWarpCpyFn' is a pointer to a function that transfers
-///     reduced variables across warps.  It tunnels, through CUDA
-///     shared memory, the thread-private data of type 'ReduceData'
-///     from lane 0 of each warp to a lane in the first warp.
-/// 4. Call the OpenMP runtime on the GPU to reduce across teams.
-///    The last team writes the global reduced value to memory.
-///
-///     ret = __kmpc_nvptx_teams_reduce_nowait(...,
-///             reduceData, shuffleReduceFn, interWarpCpyFn,
-///             scratchpadCopyFn, loadAndReduceFn)
-///
-///     'scratchpadCopyFn' is a helper that stores reduced
-///     data from the team master to a scratchpad array in
-///     global memory.
-///
-///     'loadAndReduceFn' is a helper that loads data from
-///     the scratchpad array and reduces it with the input
-///     operand.
-///
-///     These compiler generated functions hide address
-///     calculation and alignment information from the runtime.
-/// 5. if ret == 1:
-///     The team master of the last team stores the reduced
-///     result to the globals in memory.
-///     foo += reduceData.foo; bar *= reduceData.bar
-///
-///
-/// Warp Reduction Algorithms
-///
-/// On the warp level, we have three algorithms implemented in the
-/// OpenMP runtime depending on the number of active lanes:
-///
-/// Full Warp Reduction
-///
-/// The reduce algorithm within a warp where all lanes are active
-/// is implemented in the runtime as follows:
-///
-/// full_warp_reduce(void *reduce_data,
-///                  kmp_ShuffleReductFctPtr ShuffleReduceFn) {
-///   for (int offset = WARPSIZE/2; offset > 0; offset /= 2)
-///     ShuffleReduceFn(reduce_data, 0, offset, 0);
-/// }
-///
-/// The algorithm completes in log(2, WARPSIZE) steps.
-///
-/// 'ShuffleReduceFn' is used here with lane_id set to 0 because it is
-/// not used therefore we save instructions by not retrieving lane_id
-/// from the corresponding special registers.  The 4th parameter, which
-/// represents the version of the algorithm being used, is set to 0 to
-/// signify full warp reduction.
-///
-/// In this version, 'ShuffleReduceFn' behaves, per element, as follows:
-///
-/// #reduce_elem refers to an element in the local lane's data structure
-/// #remote_elem is retrieved from a remote lane
-/// remote_elem = shuffle_down(reduce_elem, offset, WARPSIZE);
-/// reduce_elem = reduce_elem REDUCE_OP remote_elem;
-///
-/// Contiguous Partial Warp Reduction
-///
-/// This reduce algorithm is used within a warp where only the first
-/// 'n' (n <= WARPSIZE) lanes are active.  It is typically used when the
-/// number of OpenMP threads in a parallel region is not a multiple of
-/// WARPSIZE.  The algorithm is implemented in the runtime as follows:
-///
-/// void
-/// contiguous_partial_reduce(void *reduce_data,
-///                           kmp_ShuffleReductFctPtr ShuffleReduceFn,
-///                           int size, int lane_id) {
-///   int curr_size;
-///   int offset;
-///   curr_size = size;
-///   mask = curr_size/2;
-///   while (offset>0) {
-///     ShuffleReduceFn(reduce_data, lane_id, offset, 1);
-///     curr_size = (curr_size+1)/2;
-///     offset = curr_size/2;
-///   }
-/// }
-///
-/// In this version, 'ShuffleReduceFn' behaves, per element, as follows:
-///
-/// remote_elem = shuffle_down(reduce_elem, offset, WARPSIZE);
-/// if (lane_id < offset)
-///     reduce_elem = reduce_elem REDUCE_OP remote_elem
-/// else
-///     reduce_elem = remote_elem
-///
-/// This algorithm assumes that the data to be reduced are located in a
-/// contiguous subset of lanes starting from the first.  When there is
-/// an odd number of active lanes, the data in the last lane is not
-/// aggregated with any other lane's dat but is instead copied over.
-///
-/// Dispersed Partial Warp Reduction
-///
-/// This algorithm is used within a warp when any discontiguous subset of
-/// lanes are active.  It is used to implement the reduction operation
-/// across lanes in an OpenMP simd region or in a nested parallel region.
-///
-/// void
-/// dispersed_partial_reduce(void *reduce_data,
-///                          kmp_ShuffleReductFctPtr ShuffleReduceFn) {
-///   int size, remote_id;
-///   int logical_lane_id = number_of_active_lanes_before_me() * 2;
-///   do {
-///       remote_id = next_active_lane_id_right_after_me();
-///       # the above function returns 0 of no active lane
-///       # is present right after the current lane.
-///       size = number_of_active_lanes_in_this_warp();
-///       logical_lane_id /= 2;
-///       ShuffleReduceFn(reduce_data, logical_lane_id,
-///                       remote_id-1-threadIdx.x, 2);
-///   } while (logical_lane_id % 2 == 0 && size > 1);
-/// }
-///
-/// There is no assumption made about the initial state of the reduction.
-/// Any number of lanes (>=1) could be active at any position.  The reduction
-/// result is returned in the first active lane.
-///
-/// In this version, 'ShuffleReduceFn' behaves, per element, as follows:
-///
-/// remote_elem = shuffle_down(reduce_elem, offset, WARPSIZE);
-/// if (lane_id % 2 == 0 && offset > 0)
-///     reduce_elem = reduce_elem REDUCE_OP remote_elem
-/// else
-///     reduce_elem = remote_elem
-///
-///
-/// Intra-Team Reduction
-///
-/// This function, as implemented in the runtime call
-/// '__kmpc_nvptx_parallel_reduce_nowait_v2', aggregates data across OpenMP
-/// threads in a team.  It first reduces within a warp using the
-/// aforementioned algorithms.  We then proceed to gather all such
-/// reduced values at the first warp.
-///
-/// The runtime makes use of the function 'InterWarpCpyFn', which copies
-/// data from each of the "warp master" (zeroth lane of each warp, where
-/// warp-reduced data is held) to the zeroth warp.  This step reduces (in
-/// a mathematical sense) the problem of reduction across warp masters in
-/// a block to the problem of warp reduction.
-///
-///
-/// Inter-Team Reduction
-///
-/// Once a team has reduced its data to a single value, it is stored in
-/// a global scratchpad array.  Since each team has a distinct slot, this
-/// can be done without locking.
-///
-/// The last team to write to the scratchpad array proceeds to reduce the
-/// scratchpad array.  One or more workers in the last team use the helper
-/// 'loadAndReduceDataFn' to load and reduce values from the array, i.e.,
-/// the k'th worker reduces every k'th element.
-///
-/// Finally, a call is made to '__kmpc_nvptx_parallel_reduce_nowait_v2' to
-/// reduce across workers and compute a globally reduced value.

Subject: [PATCH 636/771] [Matrix] Only run matrix lowering early with -O0.

Currently matrix lowering is run twice if OptLevel > 0. Fix that and
also add a test for OptLevel > 0 with matrix lowering enabled.

Subject: [PATCH 637/771] [ARM][MVE] Reorg of the LV tail-folding tests

It was getting difficult to see which test was in which file, so this
reorganises the test files so that now all filenames start with tail-folding-*
followed by a more descriptive name what that group of tests check.

Subject: [PATCH 638/771] Revert "[llvm-exegesis] Add benchmark latency option
 on X86 that uses LBR for more precise measurements."
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From @erichkeane:
```
This patch doesn't seem to build for me:
/iusers/ekeane1/workspaces/llvm-project/llvm/tools/llvm-exegesis/lib/X86/X86Counter.cpp: In function ‘llvm::Error llvm::exegesis::parseDataBuffer(const char*, size_t, const void*, const void*, llvm::SmallVector<long int, 4>*)’:
/iusers/ekeane1/workspaces/llvm-project/llvm/tools/llvm-exegesis/lib/X86/X86Counter.cpp:99:37: error: ‘struct perf_branch_entry’ has no member named ‘cycles’

CycleArray->push_back(Entry.cycles);
I'm on RHEL7, so I have kernel 3.10, so it doesn't have 'cycles'.

According ot this: https://elixir.bootlin.com/linux/v4.3/source/include/uapi/linux/perf_event.h#L963 kernel 4.3 is the first time that 'cycles' appeared in this structure.

+ Specify the run mode. Note that if you pick `analysis` mode, you also need

+ `-analysis-inconsistencies-output-file=`.
 
- `latency` mode can be  make use of either RDTSC or LBR.
- `latency[LBR]` is only available on X86 (at least `Skylake`).
- To run in this mode, a positive value  must be specified for `x86-lbr-sample-period` and `--repetition-mode=loop`
-
- In `analysis` mode, you also need to specify at least one of the
- `-analysis-clusters-output-file=` and `-analysis-inconsistencies-output-file=`.
-
-.. option:: -x86-lbr-sample-period=<nBranches/sample>
-
-  Specify the LBR sampling period - how many branches before we take a sample.
-  When a positive value is specified for this option and when the mode is `latency`,
-  we will use LBRs for measuring.
-  On choosing the "right" sampling period, a small value is preferred, but throttling
-  could occur if the sampling is too frequent. A prime number should be used to
-  avoid consistently skipping certain blocks.
-  
 .. option:: -repetition-mode=[duplicate|loop|min]
 
  Specify the repetition mode. `duplicate` will create a large, straight line

Subject: [PATCH 640/771] Introducing llvm-libtool-darwin

This diff starts the implementation of llvm-libtool-darwin
(an llvm based replacement of cctool's libtool).
Libtool is used for creating static and dynamic libraries
from a bunch of object files given as input.

Subject: [PATCH 641/771] [mlir][EDSC] Allow conditionBuilder to capture the
 IfOp

When the IfOp returns values, it can easily be obtained from one of the Values.
However, when no values are returned, the information is lost.
This revision lets the caller specify a capture IfOp* to return the produced
IfOp.

Differential Revision: https://reviews.llvm.org/D84025

Subject: [PATCH 645/771] [gn build] Make sync_source_lists_from_cmake handle
 one-line sources lines

sync_source_lists_from_cmake now also looks for source files in
`sources += [ "foo.cc" ]` lines, which allows us to remove most
`# Make `gn format` not collapse this` comments.

(sync_source_lists_from_cmake doesn't look for `foo_headers += [...]`
still, so the comment is still needed in two places for that.)

No intentional behavior change.

Subject: [PATCH 646/771] [mlir] [vector] Add an optional filter to vector
 contract lowering patterns.

Summary: Vector contract patterns were only parameterized by a `vectorTransformsOptions`. As a result, even if an mlir file was containing several occurrences of `vector.contract`, all of them would be lowered in the same way. More granularity might be required . This Diff adds a `constraint` argument to each of these patterns which allows the user to specify with more precision on which `vector.contract` should each of the lowering apply.

Differential Revision: https://reviews.llvm.org/D83960

Subject: [PATCH 648/771] [IR] Fix MSVC warning (NFC)

As requested by Andrew Kaylor, rewrite this code in a way that does
not warn on old MSVC versions.

Avoid the buggy constexpr warning by just not using constexpr and
removing the static_assert that depends on it.

Subject: [PATCH 650/771] [OptTable] Support grouped short options

POSIX.1-2017 12.2 Utility Syntax Guidelines, Guideline 5 says:

> One or more options without option-arguments, followed by at most one option that takes an option-argument, should be accepted when grouped behind one '-' delimiter.

i.e. -abc represents -a -b -c. The grouped short options are very common.  Many
utilities extend the syntax by allowing (an option with an argument) following a
sequence of short options.

This patch adds the support to OptTable, similar to cl::Group for CommandLine
(D58711).  llvm-symbolizer will use the feature (D83530). CommandLine is exotic
in some aspects. OptTable is preferred if the user wants to get rid of the
behaviors.

* `cl::opt<bool> i(...)` can be disabled via -i=false or -i=0, which is
  different from conventional --no-i.
* Handling --foo & --no-foo requires a comparison of argument positions,
  which is a bit clumsy in user code.

OptTable::parseOneArg (non-const reference InputArgList) is added along with
ParseOneArg (const ArgList &). The duplicate does not look great at first
glance. However, The implementation can be simpler if ArgList is mutable.
(ParseOneArg is used by clang-cl (FlagsToInclude/FlagsToExclude) and lld COFF
(case-insensitive). Adding grouped short options can make the function even more
complex.)

The implementation allows a long option following a group of short options. We
probably should refine the code to disallow this in the future. Allowing this
seems benign for now.

Subject: [PATCH 651/771] With MSVC, file needs to be compiled with /BIGOBJ

MSVC, by default, limits the number of sections generated by a single
translation unit to 2^16.  In a debug build, each function or method
can require 4 sections, so it's not uncommon to hit it.

I saw the problem when building tests for LLDB (but, interestingly, not
for LLDB itself).

Subject: [PATCH 652/771] BPF: generate .rodata BTF datasec for certain
 initialized local var's

Currently, BTF datasec type for .rodata is generated only if there are
user-defined readonly global variables which have debuginfo generated.

Certain readonly global variables may be generated from initialized
local variables. For example,
  void foo(const void *);
  int test() {
    const struct {
      unsigned a[4];
      char b;
    } val = { .a = {2, 3, 4, 5}, .b = 6 };
    foo(&val);
    return 0;
  }

The clang will create a private linkage const global to store
the initialized value:
  @__const.test.val = private unnamed_addr constant %struct.anon
      { [4 x i32] [i32 2, i32 3, i32 4, i32 5], i8 6 }, align 4

This global variable eventually is put in .rodata ELF section.

If there is .rodata ELF section, libbpf expects a BTF .rodata
datasec as well even though it may be empty meaning there are no
global readonly variables with proper debuginfo. Martin reported
a bug where without this empty BTF .rodata datasec, the bpftool
gen will exit with an error.

This patch fixed the issue by generating .rodata BTF datasec
if there exists local var intial data which will result in
.rodata ELF section.

Subject: [PATCH 653/771] [clang][Tooling] Try to avoid file system access if
 there is no record for the file in compile_commads.json

Summary:
If there is no record in compile_commands.json, we try to find suitable record with `MatchTrie.findEquivalent()` call.
This is very expensive operation with a lot of `llvm::sys::fs::equivalent()` calls in some cases.

This patch disables file symlinks for performance reasons.

Example scenario without this patch:
- compile_commands.json generated at clangd build (contains ~3000 files).
- it tooks more than 1 second to get compile command for newly created file in the root folder of LLVM project.
- we wait for 1 second every time when clangd requests compile command for this file (at file change).

Subject: [PATCH 657/771] [lldb] Unify sleep and time outs in GDB remote
 testcases

Reduce sleep and time outs in GDB remote testcases to one default value
for each. Stop passing these values around and always use the default
instead.

I've got the report clang11 issues signed/unsigned mismatch
warning here. For some reason only clang11 seems to issue
this warning.

Subject: [PATCH 659/771] [OpenMP] libomp: add itt notifications for teams
 construct on host

Add barrier/region notification for parallel inside teams construct
when number of teams is 1, as VTune only shows outer level regions for
simplicity.

Subject: [PATCH 666/771] Pass -rtlib=libgcc in tests conditioned on the
 default.

Summary:
* This test was failing in our builds that configure compiler-rt as the configure-time rtlib.
* Opted for this test fix instead of a rollback, and hopefully TI can fix forward if this weakens the tests beyond expectations.
* Suspected this failure introduced in D81676.

Subject: [PATCH 671/771] [InstCombine] Fold  X sdiv (-1 << C) -> -(X u>> Y) 
 iff X is non-negative

This is the one i'm seeing as missed optimization,
although there are likely other possibilities, as usual.

There are 4 variants of a general sdiv->udiv fold:
https://rise4fun.com/Alive/VS6

Name: v0
Pre: C0 >= 0 && C1 >= 0
%r = sdiv i8 C0, C1
  =>
%r = udiv i8 C0, C1

Name: v1
Pre: C0 <= 0 && C1 >= 0

If we really don't like sdiv (more than udiv that is),
and are okay with increasing instruction count (2 new negations),
and we ensure that we don't undo the fold,
then we could just implement these..

Subject: [PATCH 673/771] [GWP-ASan] Split the unwinder into segv/non-segv.

Summary:
Splits the unwinder into a non-segv (for allocation/deallocation traces) and a
segv unwinder. This ensures that implementations can select an accurate, slower
unwinder in the segv handler (if they choose to use the GWP-ASan provided one).
This is important as fast frame-pointer unwinders (like the sanitizer unwinder)
don't like unwinding through signal handlers.

Subject: [PATCH 674/771] [AIX] report_fatal_error on
 `-fregister_global_dtors_with_atexit` for static init

On AIX, the semantic of global_dtors contains __sterm functions associated with C++
cleanup actions and user-declared __attribute__((destructor)) functions. We should
never merely register __sterm with atexit(), so currently
-fregister_global_dtors_with_atexit does not work well on AIX: It would cause
finalization actions to not occur when unloading shared libraries.  We need to figure
out a way to handle that when we start supporting user-declared
__attribute__((destructor)) functions.

Currently we report_fatal_error on this option temporarily.

Subject: [PATCH 675/771] [InlineAdvisor] New inliner advisor to replay
 inlining from optimization remarks

Summary:
This change added a new inline advisor that takes optimization remarks for previous inlining as input, and provide the decision as advice so current inlining can replay inline decision of a different compilation. Dwarf inline stack with line and discriminator is used as anchor for call sites. The change can be useful for Inliner tuning.
A switch -sample-profile-inline-replay=<inline_remarks_file> is added to hook up the new inliner advisor with SampleProfileLoader's inline decision for replay. The new inline advisor can also be used by regular CGSCC inliner later if needed.

Subject: [PATCH 677/771] [flang] Rework read/write permission management for
 runtime file opening

Anonymous Fortran unit files (e.g., "./fort.7") need to be created
O_RDWR so that they can be written, rewound, and read.  Other
files opened with no ACTION= specifier need to set read/write
permissions based on the file, if it exists.

Subject: [PATCH 680/771] Temporarily Revert "[InlineAdvisor] New inliner
 advisor to replay inlining from optimization remarks" as it is failing the
 inline-replay.ll test as well as sanitizers/Werror from returning a stack
 local variable.

This reverts commit 029946b112684c27b27f7c2d7554f22b33ae1e0b.

Subject: [PATCH 681/771] Temporarily Revert "[OpenMP] Add Additional Function
 Attribute Information to OMPKinds.def" as it's causing a few unused variable
 warnings via the macro instantiation:

sources/llvm-project/llvm/include/llvm/Frontend/OpenMP/OMPKinds.def:649:17: error: unused variable 'InaccessibleOnlyAttrs' [-Werror,-Wunused-variable]
__OMP_ATTRS_SET(InaccessibleOnlyAttrs,
                ^

This reverts commit 09fe0c5ab9ca5846d6cb625e9be47fdcfe49b93c.

Subject: [PATCH 682/771] [clangd] Fix the build with clang <3.9.

In clang <3.9 the `unique_ptr` constructor that is supposed to allow
for Derived to Base conversion does not work. Remove this if we drop
support for such configurations.

This is the same fix as in fda901a987ddd, and it updates the comments
to better reflect the actual issue. The same thing reproduces with
libc++ with older clangs.

Subject: [PATCH 683/771] [OpenMP] libomp cleanup: check presence of hwloc
 objects CORE, PACKAGE

hwloc documentation guarantees the only object that is always present
in the topology is PU. We can check the presence of other objects
in the topology, just in case.

Subject: [PATCH 684/771] [flang] Allow ! and // comments after some
 preprocessing directives

Old-style C /*comments*/ are omitted from preprocessor directive
token sequences by the prescanner, but line-ending C++ and Fortran
free-form comments are not since their handling might depend on
the directive.  Add code to skip these line-ending comments as
appropriate in place of existing code that just skipped blanks.

Subject: [PATCH 685/771] Revert "[AddressSanitizer] Don't use weak linkage for
 __{start,stop}_asan_globals"

This reverts commit d76e62fdb7a93d9a33f642b6b528f2562cc3c3f4.

Reverting since this can lead to linker errors:

```
ld.lld: error: undefined hidden symbol: __start_asan_globals
```

when using --gc-sections. The linker can discard __start_asan_globals
once there are no more `asan_globals` sections left, which can lead to
this error if we have external linkages to them.

The `intrinsics_gen` target exists in the CMake exports since r309389

even it they are built separately from LLVM.

Subject: [PATCH 689/771] [flang] Support <name>=<integer> syntax in compiler
 directives

Accept name=value as part of a !DIR$ compiler directive.  These
are currently ignored in semantics, but we should recognize
more directive forms to facilitate testing.  In due course,
these placeholding directive parsers will be replaced.

Subject: [PATCH 691/771] [flang] Prevent bogus runtime I/O error message

The runtime was requiring that STATUS='OLD' be explicitly specified
on an OPEN statement for a connected unit.  There error should issue
only if a STATUS= other than 'OLD' is specified; an OPEN with no
STATUS= specifier is okay.

Subject: [PATCH 698/771] [NewPM][ASan] Make ASan tests work under NPM

Under NPM, the asan-globals-md analysis is required but cannot be run
within the asan function pass due to module analyses not being able to
run from a function pass. So this pins all tests using "-asan" to the
legacy PM and adds a corresponding RUN line with
-passes='require<asan-globals-md>,function(asan)'.

Now all tests in Instrumentation/AddressSanitizer pass when
-enable-new-pm is by default on.

Tests were automatically converted using the following python script and
failures were manually fixed up.

import sys
for i in sys.argv:
    with open(i, 'r') as f:
        s = f.read()
    with open(i, 'w') as f:
        for l in s.splitlines():
            if "RUN:" in l and ' -asan -asan-module ' in l and '\\' not in l:
                f.write(l.replace(' -asan -asan-module ', ' -asan -asan-module -enable-new-pm=0 '))
                f.write('\n')
                f.write(l.replace(' -asan -asan-module ', " -passes='require<asan-globals-md>,function(asan),module(asan-module)' "))
                f.write('\n')
            elif "RUN:" in l and ' -asan ' in l and '\\' not in l:
                f.write(l.replace(' -asan ', ' -asan -enable-new-pm=0 '))
                f.write('\n')
                f.write(l.replace(' -asan ', " -passes='require<asan-globals-md>,function(asan)' "))
                f.write('\n')
            else:
                f.write(l)
                f.write('\n')

Subject: [PATCH 699/771] Corrected __libfuzzer_is_present symbol inclusion for
 MSVC x86 32-bit

The incorrect symbol will cause linking failures for 32-bit targets:

clang_rt.fuzzer-i386.lib(FuzzerDriver.obj) : error LNK2001: unresolved external symbol __libfuzzer_is_present

Verified no longer fails to link with this change for 32-bit and still succeeds for 64-bit MSVC.

Subject: [PATCH 700/771] [OpenMP] Fix map clause for unused var: don't ignore
 it

For example, without this patch:

```
 $ cat test.c
 int main() {
   int x[3];
   #pragma omp target map(tofrom:x[0:3])
 #ifdef USE
   x[0] = 1
 #endif
   ;
   return 0;
 }
 $ clang -fopenmp -fopenmp-targets=nvptx64-nvidia-cuda -S -emit-llvm test.c
 $ grep '^@.offload_maptypes' test.ll
 $ echo $?
 1
 $ clang -fopenmp -fopenmp-targets=nvptx64-nvidia-cuda -S -emit-llvm test.c \
         -DUSE
 $ grep '^@.offload_maptypes' test.ll
 @.offload_maptypes = private unnamed_addr constant [1 x i64] [i64 35]
```

With this patch, both greps produce the same result.

Subject: [PATCH 708/771] [RelocationResolver] Support R_PPC_REL32 &
 R_PPC64_REL{32,64}

This suppresses `failed to compute relocation: R_PPC_REL32, Invalid data was encountered while parsing the file`
and its 64-bit variants when running llvm-dwarfdump on a PowerPC object file with .eh_frame

Unfortunately it is difficult to test the computation:
DWARFDataExtractor::getEncodedPointer does not use the relocated value
and even if it does, we need to teach llvm-dwarfdump --eh-frame to do
some linker job to report a reasonable address.

Subject: [PATCH 716/771] [NFC][CVP] Add tests for possible sdiv->udiv where
 operands are not non-negative

Currently that fold requires both operands to be non-negative,
but the only real requirement for the fold is that we must know
the domains of the operands.

Subject: [PATCH 719/771] [CVP] Soften SDiv into a UDiv as long as we know
 domains of both of the operands.

Yes, if operands are non-positive this comes at the extra cost
of two extra negations. But  a. division is already just
ridiculously costly, two more subtractions can't hurt much :)
and  b. we have better/more analyzes/folds for an unsigned division,
we could end up narrowing it's bitwidth, converting it to lshr, etc.

This is essentially a take two on 0fdcca07ad2c0bdc2cdd40ba638109926f4f513b,
which didn't fix the potential regression i was seeing,
because ValueTracking's computeKnownBits() doesn't make use
of dominating conditions in it's analysis.
While i could teach it that, this seems like the more general fix.

This big hammer actually does catch said potential regression.

Over vanilla test-suite + RawSpeed + darktable
(10M IR instrs, 1M IR BB, 1M X86 ASM instrs), this fires/converts 5 more
(+2%) SDiv's, the total instruction count at the end of middle-end pipeline
is only +6, so out of +10 extra negations, ~half are folded away,
and asm instr count is only +1, so practically speaking all extra
negations are folded away and are therefore free.
Sadly, all these new UDiv's remained, none folded away.
But there are two less basic blocks.

Subject: [PATCH 720/771] [PredicateInfo] Fold PredicateWithCondition into
 PredicateBase (NFC).

Each concrete instance of a predicate has a condition (also noted in the
original PredicateBase comment) and to me it seems like there is no
clear benefit of having both PredicateBase and PredicateWithCondition
and they can be folded together.

Subject: [PATCH 722/771] [clang-format] Make sure rst documentation matches
 comments

clang/docs/tools/dump_format_style.py is used to read the comments
from clang/include/clang/Format/Format.h and update the contents of
clang/docs/ClangFormatStyleOptions.rst

Recent changes made these out of date. This commit syncs them by
folding the improved wording back to the comments and then
regenerating the rst file.

     The "view" operation extracts an N-D contiguous memref with empty layout map

     The "view" operation gives a structured indexing form to a flat 1-D buffer.
     Unlike "subview" it can perform a type change. The type change behavior
     requires the op to have special semantics because, e.g. a byte shift of 3
     cannot be represented as an offset on f64.
     For now, a "view" op:
-      1) Only takes a contiguous source memref with 0 offset and empty layout.
-      2) Must specify a byte_shift operand (in the future, a special integer
-      attribute may be added to support the folded case).
-      3) Returns a contiguous memref with 0 offset and empty layout.

Subject: [PATCH 732/771] [clang] Provide a more specific diagnostic for a
 misplaced lambda capture-default.

Currently a capture-default which is not the first element in the lambda-capture
is diagnosed with a generic expected variable name or 'this' in lambda capture
list, which is true but not very helpful.

If we don't have already parsed a capture-default then a lone "&" or "=" is
likely to be a misplaced capture-default, so diagnose it as such.

Subject: [PATCH 737/771] [gcov] Add __gcov_dump/__gcov_reset and delete
 __gcov_flush

GCC r187297 (2012-05) introduced `__gcov_dump` and `__gcov_reset`.
  `__gcov_flush = __gcov_dump + __gcov_reset`

The resolution to https://gcc.gnu.org/PR93623 ("No need to dump gcdas when forking" target GCC 11.0) removed the unuseful and undocumented __gcov_flush.

Close PR38064.

Subject: [PATCH 739/771] [Driver] -B: don't search for target triple prefixes

To match GCC (either crossing or not), which doesn't prepend target triple prefixes to `exec_prefixes`.

As an example, powerpc64le-linux-gnu-gcc does not search "powerpc64le-linux-gnu-${name}" in a -B path.

Subject: [PATCH 741/771] [NewPM] make parsePassPipeline parse adaptor-wrapped
 user passes

Currently, when parsing text pipeline, different kinds of passes always
introduce nested pass managers. This makes it impossible to test the
adaptor-wrapped user passes from the text pipeline interface which is needed
by D82344 test cases. This also seems useful in general. See comments above
`parsePassPipeline`.

The syntax would be like mixing passes of different types, but it is
not the same as inferring the correct pass type and then adding the
matching nested pass managers. Strictly speaking, the resulted pipelines
are different.

Subject: [PATCH 742/771] [NewPM] Allow passes to never be skipped

A pass declares itself unskippable by defining a method `static bool isRequired()`.

Also, this patch makes pass managers and adaptor passes required (unskippable).

PassInstrumentation before-pass-callbacks could be used to skip passes by returning false.
However, some passes should not be skipped at all. Especially so for special-purpose passes such as pass managers and adaptor passes since if they are skipped for any reason, the passes contained by them would also be skipped ignoring contained passes's return value of `isRequired()`.

Subject: [PATCH 743/771] [PowerPC] Remove the redundant implicit operands in
 ppc-early-ret pass

Summary:
In the `ppc-early-ret` pass, we have use `BuildMI` and `copyImplicitOps` when the branch instructions can do the early return. But the two functions will add implicit operands twice, this is not correct.

This patch is to remove the redundant implicit operands in `ppc-early-ret pass`.

Subject: [PATCH 744/771] [llvm-cov gcov] Don't require NUL terminator when
 reading files

.gcno, .gcda and source files can be modified while we are reading them. If the
concurrent modification of a file being read nullifies the NUL terminator
assumption, llvm-cov can trip over an assertion failure in MemoryBuffer::init.
This is not so rare - the source files can be in an editor and .gcda can be
written by an running process (if the process forks, when .gcda gets written is
probably more unpredictable).

There is no accompanying test because an assertion failure requires data
races with some involved setting.

Subject: [PATCH 745/771] [ARM] Don't mark vctp as having sideeffects

As far as I can tell, it should not be necessary for VCTP to be
unpredictable in tail predicated loops. Either it has a a valid loop
counter as a operand which will naturally keep it in the right loop, or
it doesn't and it won't be converted to a tail predicated loop. Not
marking it as having side effects allows it to be scheduled more cleanly
for cases where it is not expected to become a tail predicate loop.

Subject: [PATCH 746/771] [InstCombine] Fix store merge worklist management
 (PR46680)

Fixes https://bugs.llvm.org/show_bug.cgi?id=46680.

Just like insertions through IRBuilder, InsertNewInstBefore()
should be using the deferred worklist mechanism, so that processing
of newly added instructions is prioritized.

There's one side-effect of the worklist order change which could be
classified as a regression. An add op gets pushed through a select
that at the time is not a umax. We could add a reverse transform
that tries to push adds in the reverse direction to restore a min/max,
but that seems like a sure way of getting infinite loops... Seems
like something that should best wait on min/max intrinsics.

Subject: [PATCH 747/771] [InstSimplify] fold fcmp with infinity constant using
 isKnownNeverInfinity

This is a step towards trying to remove unnecessary FP compares
with infinity when compiling with -ffinite-math-only or similar.
I'm intentionally not checking FMF on the fcmp itself because
I'm assuming that will go away eventually.
The analysis part of this was added with rGcd481136 for use with
isKnownNeverNaN. Similarly, that could be an enhancement here to
get predicates like 'one' and 'ueq'.

Subject: [PATCH 748/771] [NFCI][GVN] Make IsValueFullyAvailableInBlock()
 readable - use enum class instead of magic numbers

This does not change any logic, it only wraps the magic 0/1/2/3 constants
into an enum class.

Subject: [PATCH 749/771] [PredicateInfo] Add a method to interpret predicate
 as cmp constraint

Both users of predicteinfo (NewGVN and SCCP) are interested in
getting a cmp constraint on the predicated value. They currently
implement separate logic for this. This patch adds a common method
for this in PredicateBase.

This enables a missing bit of PredicateInfo handling in SCCP: Now
the predicate on the condition itself is also used. For switches
it means we know that the switched-on value is the same as the case
value. For assumes/branches we know that the condition is true or
false.

Subject: [PATCH 750/771] Reland "[InstCombine] Lower infinite combine loop
 detection thresholds"

This reverts commit 4500db8c59621a31c622862a2946457fdee481ce,
which was reverted because lower thresholds exposed a new issue (PR46680).

Now that it was resolved by d12ec0f752e7f2c7f7252539da2d124264ec33f7,
we can reinstate lower limits and wait for a new bugreport before
reverting this again...

Subject: [PATCH 751/771] [x86] split FMA with fast-math-flags to avoid libcall

fma reassoc A, B, C --> fadd (fmul A, B), C (when target has no FMA hardware)

C/C++ code may use explicit fma() calls (which become LLVM fma
intrinsics in IR) but then gets compiled with -ffast-math or similar.
For targets that do not have FMA hardware, we don't want to go out to
the math library for a precise but slow FMA result.

I tried this as a generic DAGCombine, but it caused infinite looping
on more than 1 other target, so there's likely some over-reaching fma
formation happening.

There's also a potential intersection of strict FP with fast-math here.
Deferring to current behavior for that case (assuming that strict-ness
overrides fast-ness).

Subject: [PATCH 755/771] [InlineAdvisor] New inliner advisor to replay
 inlining from optimization remarks

Summary:
This change added a new inline advisor that takes optimization remarks from previous inlining as input, and provides the decision as advice so current inlining can replay inline decisions of a different compilation. Dwarf inline stack with line and discriminator is used as anchor for call sites including call context. The change can be useful for Inliner tuning as it provides a channel to allow external input for tweaking inline decisions. Existing alternatives like alwaysinline attribute is per-function, not per-callsite. Per-callsite inline intrinsic can be another solution (not yet existing), but it's intrusive to implement and also does not differentiate call context.

A switch -sample-profile-inline-replay=<inline_remarks_file> is added to hook up the new inline advisor with SampleProfileLoader's inline decision for replay. Since SampleProfileLoader does top-down inlining, inline decision can be specialized for each call context, hence we should be able to replay inlining accurately. However with a bottom-up inliner like CGSCC inlining, the replay can be limited due to lack of specialization for different call context. Apart from that limitation, the new inline advisor can still be used by regular CGSCC inliner later if needed for tuning purpose.

Subject: [PATCH 757/771] [clang] Disable a few formatting options for test/

Hopefully this will make the bot a little less noisy. Rationale for each:

AlignTrailingComments: We don't want to force-align the various expected-error
                       and friends.

CommentPragmas:       Tell clang-format to leave the "// CHECK:" and the
                      "// expected-" alone.

AlwaysBreakTemplateDeclarations: Templates in tests often have no break between
                                 the template-head and the declaration.

Subject: [PATCH 758/771] [clang] Fix the warning for a non-void consteval
 function without a return value to actually say "consteval".

This warning was modified in 796ed03b8412 to use the term "consteval"
for consteval functions. However the warning has never worked as
intended since the diagnostic's arguments are used in the wrong order.

This was unfortunately missed by 796ed03b8412 since no test did exercise
this specific warning.

Additionally send the NamedDecl* into the diagnostic instead of just the
IdentifierInfo* to correctly work with special names and template
arguments.

Subject: [PATCH 764/771] [JITLink][MachO] Fix handling of non-extern UNSIGNED
 pair of SUBTRACTOR relocs.

When processing a MachO SUBTRACTOR/UNSIGNED pair, if the UNSIGNED target
is non-extern then check the r_symbolnum field of the relocation to find
the targeted section and use the section's address to find 'ToSymbol'.

Previously 'ToSymbol' was found by loading the initial value stored at
the fixup location and treating this as an address to search for. This
is incorrect, however: the initial value includes the addend and will
point to the wrong block if the addend is less than zero or greater than
the block size.

Subject: [PATCH 769/771] Fix type mapping for pointers with
 Device/HostOnlyINTEL storage classes

a7b763b265d introduces a bug, when it could be possible to map a
single pointer type in LLVM IR to two different pointer types in
SPIR-V (when SPV_INTEL_usm_storage_classes extension is not allowed).
This patch fixes this bug.
