[libc++][test] Enhance ADDITIONAL_COMPILE_FLAGS, use TEST_MEOW_DIAGNOSTIC_IGNORED sparingly
#75317

Also refactor `_isClang` and `_isGCC`.
…ally suppress MSVC warning C4310.
…warnings. This avoids using the internal macros `_LIBCPP_SUPPRESS_DEPRECATED_PUSH`/`_LIBCPP_SUPPRESS_DEPRECATED_POP`.

@llvm/pr-subscribers-libcxx Author: Stephan T. Lavavej (StephanTLavavej) ChangesThis is the last PR that's needed (for now) to get libc++'s tests working with MSVC's STL. It returns to the overall approach of #74974 by enhancing I thought it was simplest to open a fresh PR with the following well-structured commits:
Patch is 28.29 KiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/75317.diff 35 Files Affected:

There was a problem hiding this comment.
LGTM too.
Just a heads up, I'm working on an overhall involving how we configure the test suite.
Specifically we want to de-couple the CMake/library build options from the options we use to configure the test suite (So we can better support M:N build configurations to test configurations.)
I don't think this will affect your upstream magic LIT configs much, but if it starts to, let me know.

@EricWF Will do! Hopefully we'll be able to update our llvm-project submodule more frequently so we should be able to notice issues faster (GitHub pull requests help so much 😻). |

… `-Wno-psabi` (llvm#113608) MSVC doesn't understand `-Wno-psabi`, which was introduced here by @ldionne in llvm#106077. Using `ADDITIONAL_COMPILE_FLAGS(gcc-style-warnings)` (implemented by llvm#75317) avoids passing this to MSVC.

This is the last PR that's needed (for now) to get libc++'s tests working with MSVC's STL.
It returns to the overall approach of #74974 by enhancing
ADDITIONAL_COMPILE_FLAGSwithgcc-style-warningsandcl-style-warningsfeatures (because-Wno-meowand/wdNNNNare mutually unintelligible), addressing @philnik777's objection in #75133 (review) by keeping #75133's approach of introducingTEST_MEOW_DIAGNOSTIC_IGNOREDonly for local suppressions. The result is a minimal change from the status quo (it doesn't change any files away from usingADDITIONAL_COMPILE_FLAGSfor whole-test suppressions) and should hopefully be acceptable to all maintainers.I thought it was simplest to open a fresh PR with the following well-structured commits:
gcc-style-warningsandcl-style-warnings._isClangand_isGCC.ADDITIONAL_COMPILE_FLAGS, usinggcc-style-warningsandcl-style-warnings.gcc-style-warnings.gcc-style-warningsandcl-style-warnings, locally suppress MSVC warning C4310._LIBCPP_SUPPRESS_DEPRECATED_PUSH/_LIBCPP_SUPPRESS_DEPRECATED_POP.#pragma GCC diagnostic ignored "-Wvolatile"for a whole-test suppression, but that doesn't need to apply to product code headers, so there wasn't a weird dance of having to include"test_macros.h"at the very top. I've chosen a minimal change of converting this toTEST_MEOW_DIAGNOSTIC_IGNOREDin-place. If desired, I could attempt to replace this withADDITIONAL_COMPILE_FLAGSfor consistency with other whole-test suppresions._LIBCPP_SUPPRESS_DEPRECATED_PUSH/_LIBCPP_SUPPRESS_DEPRECATED_POP.
