[openmp] Fix warnings when building on Windows with latest MSVC or Clang ToT (#77853)

2024-01-23T13:38:18+00:00

There were quite a few compilation warnings when building openmp on Windows with
the latest Visual Studios 2022 version 17.8.4. Some other warnings were visible
with the latest Clang at tip. This commit fixes all of them.

[openmp] Revert 64874e5ab5fd102344d43ac9465537a44130bf19 since it was committed by mistake and the PR (https://github.com/llvm/llvm-project/pull/77853) wasn't approved yet.

[OpenMP] Let primary thread gather topology info for each worker thread

2023-08-22T20:56:51+00:00

This change has the primary thread create each thread's initial mask
and topology information so it is available immediately after
forking. The setting of mask/topology information is decoupled from the
actual binding. Also add this setting of topology information inside the
__kmp_partition_places mechanism for OMP_PLACES+OMP_PROC_BIND.

Without this, there could be a timing window after the primary
thread signals the workers to fork where worker threads have not yet
established their affinity mask or topology information.

Each worker thread will then bind to the location the primary thread
sets.

[OpenMP][libomp] Implement KMP_DLSYM_NEXT on Windows

2023-05-24T13:33:34+00:00

The interop API routines try to invoke external entries, but we did
not have support for KMP_DLSYM_NEXT on Windows. Also added proper
guards for STUB build.

[openmp] Support building for armv7 Windows with mingw tools

2022-11-25T19:46:31+00:00

This does things in the same way as
D137168 / a356782426f5bf54a00570e1f925345e5fda7b2e and
D101173 / 4fb0aaf03381473ec8af727edb4b5d59b64b0d60 did for aarch64.

This adds a C implementation of __kmp_invoke_microtask in the same
way as the fallback C implementation in z_Linux_util.cpp.

Both the existing C fallback used on arm linux, and this one added here,
fail test/misc_bugs/many-microtask-args.c similarly (which could be
considered as an XFAIL).

[OpenMP][libomp] Parameterize affinity functions

2022-10-28T20:21:06+00:00

This patch parameterizes the affinity initialization code to allow multiple
affinity settings. Almost all global affinity settings are consolidated
and put into a structure kmp_affinity_t. This is in anticipation of the
addition of hidden helper affinity which will have the same syntax and
semantics as KMP_AFFINITY only for the hidden helper team.

[OpenMP][libomp] Introduce oneAPI compiler support

2022-02-14T20:10:33+00:00

Introduce KMP_COMPILER_ICX macro to represent compilation with oneAPI
compiler.

Fixup flag detection and compiler ID detection in CMake. Older CMake's
detect IntelLLVM as Clang.

Fix compiler warnings.

Fixup many of the tests to have non-empty parallel regions as they are
elided by oneAPI compiler.
