Coverage tests produce invalid executables on x86_64-pc-windows-gnu

[ForrestOfBarnes]

Summary

Sometime bretween May 31 and now, the coverage-run tests broke on windows-gnu. Rustc no longer builds the coverage tests into valid executables, causing the coverage-run tests to fail.

Attempting to run the a.exe files manually also fails; Windows really does not see them as valid executables. Oddly, they still manage to pass the coverage-map tests.

Does this also reproduce with a more minimal example of just using coverage on hello world or is this only occuring within the test suite? If you are able to reproduce it outside the test suite and even with a nightly toolchain, you can then use cargo-bisect-rustc to bisect it.

How did you manage to run them?
They were disabled in #122613 because they were broken since the beginning (GCC bug) and worked only with gnullvm toolchains.

[ForrestOfBarnes]

I literally just cloned from source, set my bootstrap.toml, and ran ./x test. I guess at some point these tests got re-enabled?

Since I posted my issue I started bisecting manually, and this issue goes back to at least June 9th, probably further (I run into a different issue on/before June 4).

[ForrestOfBarnes]

Ah, I see. #122613 disabled the profiler in CI—I’m running an unsupported config. I recently switched from -msvc to -gnu to more easily debug the compiler, and I guess I just haven’t run the full test suite since I made the switch.

I’m gonna see if I can add a warning for this, or at least update the docs. I’ll close this when I’m done.

[mati865]

Ah, I see. #122613 disabled the profiler in CI—I’m running an unsupported config.

Yeah, that's basically true for windows-gnu unless GCC stopped misscompiling the profiler.

If you want to get it to work, you should use Clang as the C/C++ compiler. Note however, unpatched Clang is not fully compatible with GCC so you have to use CFLAGS and CXXFLAGS to force emulated TLS and link pthreads. MSYS2 for environments called MINGW* and UCRT* provides a patched version that is mostly compatible, and for CLANG* environments it provides the original, unpatched version.
