move page protection logic inside native_lib

This test depends on the target-specific behavior of crt-static for musl targets. However, running the testsuite on a musl host requires setting `crt-static` to `false`, as it wouldn't otherwise be possible to build rustc. This in turn will enable `-Ctarget-feature=-crt-static` for all tests, mismatching the expected `+crt-static` for the musl target tested in this testcase. Since this test specifically tests the default value of `crt-static` for the musl target, ignoring it entirely makes more sense than manually setting `-Ctarget-feature=+crt-static` here, but both would be valid approaches. Signed-off-by: Jens Reidel <[email protected]>

…part of float-nondet

add -Zmiri-no-extra-rounding-error to specifically disable just that part of float-nondet

…ix, r=scottmcm Option::as_slice: fix comment The implementation got changed in rust-lang#117525 without updating the comment. Now the comment makes no sense any more since there is no intrinsic that returns a pointer in this function any more. (It is also very strange to say "in the new version" in a comment -- what is that supposed to tell someone reading the code 2 years later? That wording was introduced even earlier, in rust-lang#109179.) Cc `@GKFX` `@petrochenkov` `@llogiq` `@scottmcm`

Fix run-make tests on musl hosts On musl hosts, we already set `-Ctarget-feature=-crt-static` and `IS_MUSL_HOST=1` in compiletest. However, in order for the run-make tests to compile fine on musl hosts, we need to propagate this flag in our rustc invocations to ensure we can generate cdylibs.

The CI runner couldn't find the way back to home 😔

The hosted runner lost communication with the server. Anything in your workflow that terminates the runner process, starves it for CPU/Memory, or blocks its network access can cause this error.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
