The example code for higher-ranked trait bounds on closures had an unnecessary `mut` which was confusing, and the text referred to an mutable reference which does not exist in the code (and isn't needed). Removed the `mut`s and fixed the text to better describe the actual error for the failing example.
The rustc-generated function `main` should respect the same config for frame pointer elimination as the rest of code.
Environment variables on windows can't be empty.
* Correct the stability attributes. * Make Add and AddAssign actually behave the same. * Use String::with_capacity when allocating a new string. * Fix the tests.
On 64-bit platforms this reduces the size of `Expr` from 96 bytes to 88 bytes.
On 64-bit platforms this reduces the size of `Expr_` from 64 bytes to 56 bytes, and reduces the size of `Expr` from 88 bytes to 80 bytes.
It seems to prevent it from being inlined.
The mx_cprng_draw syscall has changed signature to separate the status and size return values, rather than multiplexing them into a single value with errors interpreted as a negative value. This patch tracks that change.
Fix some mistakes in HRTB docs The example code for higher-ranked trait bounds on closures had an unnecessary `mut` which was confusing, and the text referred to an mutable reference which does not exist in the code (and isn't needed). Removed the `mut`s and fixed the text to better describe the actual error for the failing example. Thanks to csd_ on IRC for pointing out these problems! r? @steveklabnik

set frame pointer elimination attribute for main The rustc-generated function `main` should respect the same config for frame pointer elimination as the rest of code.
Use DefId's in const eval for cross-crate const fn's Fixes rust-lang#36954. r? @eddyb cc @raphaelcohn
Fix ICE when querying DefId on Def::Err. Also moves computations into check that `kind_id` is `Ok(_)`, which is in theory an optimization, though I expect it's minor. Fixes rust-lang#37534. r? @eddyb.
…hton Peekable::peek(): Use Option::as_ref() Replace the match expression in .peek() with Option::as_ref() since it's the same functionality.
Set RUSTC_BOOTSTRAP to some value. Environment variables on windows can't be empty.
Fix issues with the Add/AddAssign impls for Cow<str> * Correct the stability attributes. * Make Add and AddAssign actually behave the same. * Use String::with_capacity when allocating a new string. * Fix the tests.

…alexcrichton Change `Into<Vec<u8>> for String` and `Into<OsString> for PathBuf` to From Fixes rust-lang#37561. First contribution, happy with any and all feedback!
fix rust-lang#37559: update compiler-rt Fixes rust-lang#37559 r? @alexcrichton
Remove recursive call from Cow::to_mut It seems to prevent it from being inlined.
…chton std: Track change to cprng syscall signature (Fuchsia) The mx_cprng_draw syscall has changed signature to separate the status and size return values, rather than multiplexing them into a single value with errors interpreted as a negative value. This patch tracks that change.
Add error when proc_macro_derive is used not on functions Fixes rust-lang#37590
