--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:2bf8da684b712a16c67f3defc0dd97f175f8f4ad commit r12-6884-g2bf8da684b712a16c67f3defc0dd97f175f8f4ad Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Jan 26 22:07:29 2022 +0100 rs6000: Fix up #include <immintrin.h> or <x86gprintrin.h> [PR104239] r12-4717-g7d37abedf58d66 added immintrin.h and x86gprintrin.h headers to rs6000, these headers are on x86 standalone headers that various programs include directly rather than including them through <x86intrin.h>. Unfortunately, for that change the bmiintrin.h and bmi2intrin.h headers haven't been adjusted, so the effect is that if one includes them (without including also x86intrin.h first) #error will trigger. Furthermore, when including such headers conditionally as some real-world packages do, this means a regression. The following patch fixes it and matches what the x86 bmi{,2}intrin.h headers do. 2022-01-26 Jakub Jelinek <ja...@redhat.com> PR target/104239 * config/rs6000/bmiintrin.h: Test _X86GPRINTRIN_H_INCLUDED instead of _X86INTRIN_H_INCLUDED and adjust #error wording. * config/rs6000/bmi2intrin.h: Likewise. * gcc.target/powerpc/pr104239-1.c: New test. * gcc.target/powerpc/pr104239-2.c: New test.
