--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- What does LLVM implement? Either I'm looking at a wrong place, or at least their testsuite coverage for this is non-existing. I see no sse nor avx substrings in clang/test/OpenMP/* (except for sse2020 which looks to stand for non-existent), no power substrings, ppc only combined with that sse2020.
