--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-9 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:07d52e63d999a0a10c7598c34c48365a357d3d5a commit r9-8350-g07d52e63d999a0a10c7598c34c48365a357d3d5a Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Mar 5 19:44:42 2020 +0100 i386: Fix some -O0 avx2intrin.h and xopintrin.h intrinsic macros [PR94046] As the testcases show, the macros we have for -O0 for intrinsics that require constant argument(s) should first cast the argument to the type the -O1+ inline uses and afterwards to whatever type e.g. a builtin needs. The PR reported one which violated this, and I've grepped for all double-casts and grepped out from that meaningful casts where the __m{128,256,512}{,d,i} first cast is cast to same sized __v* type and has the same kind of element type (float, double, integral). These 7 macros were using different casts, and I've double checked them against the inline function types. 2020-03-05 Jakub Jelinek <ja...@redhat.com> PR target/94046 * config/i386/avx2intrin.h (_mm_mask_i32gather_ps): Fix first cast of SRC and MASK arguments to __m128 from __m128d.
