--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:a6b1f6126de5e45777610699b6d634605c17711c commit r12-8924-ga6b1f6126de5e45777610699b6d634605c17711c Author: Jakub Jelinek <ja...@redhat.com> Date: Mon Nov 21 10:28:27 2022 +0100 i386: Uglify some local identifiers in *intrin.h [PR107748] While reporting PR107748 (where is a problem with non-uglified names, but I've left it out because it needs fixing anyway), I've noticed various spots where identifiers in *intrin.h headers weren't uglified. The following patch fixed those that are related to unions (I've grepped for [a-zA-Z]\.[a-zA-Z] spots). The reason we need those to be uglified is the same as why the arguments of the inlines are __ prefixed and most of automatic vars in the inlines - say a, v or u aren't part of implementation namespace and so users could #define u whatever->something #include <x86intrin.h> and it should still work, as long as u is not e.g. one of the names of the functions/macros the header provides (_mm* etc.). 2022-11-21 Jakub Jelinek <ja...@redhat.com> PR target/107748 * config/i386/avx512fp16intrin.h (_mm512_castph512_ph128, _mm512_castph512_ph256, _mm512_castph128_ph512, _mm512_castph256_ph512, _mm512_set1_pch): Uglify names of local variables and union members. * config/i386/avx512fp16vlintrin.h (_mm256_castph256_ph128, _mm256_castph128_ph256, _mm256_set1_pch, _mm_set1_pch): Likewise. * config/i386/smmintrin.h (_mm_extract_ps): Likewise. * config/i386/avx512bf16intrin.h (_mm_cvtsbh_ss): Likewise.
