--- Comment #8 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:f97bf9657cecaaf8afd14b43e5ca9be294ab870c commit r9-8891-gf97bf9657cecaaf8afd14b43e5ca9be294ab870c Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Apr 29 17:30:22 2020 +0200 x86: Fix -O0 intrinsic *gather*/*scatter* macros [PR94832] As reported in the PR, while most intrinsic -O0 macro argument uses are properly wrapped in ()s or used in context where having a complex expression passed as the argument doesn't pose a problem (e.g. when macro argument use is in between commas, or between ( and comma, or between comma and ) etc.), especially the gather/scatter macros don't do this and if one passes to some macro e.g. x + y as argument, the corresponding inline function would do cast on the argument, but the macro does (int) ARG, then it is (int) x + y rather than (int) (x + y). The following patch fixes those issues in *gather/*scatter*; additionally, the AVX2 macros were passing incorrect mask of e.g. (__v2df)_mm_set1_pd((double)(long long int) -1) which is IMHO equivalent to (__v2df){-1.0, -1.0} when it really wants to pass __v2df vector with all bits set. I've used what the inline functions use for those cases. 2020-04-29 Jakub Jelinek <ja...@redhat.com> PR target/94832 * config/i386/avx2intrin.h (_mm_mask_i32gather_pd, _mm256_mask_i32gather_pd, _mm_mask_i64gather_pd, _mm256_mask_i64gather_pd, _mm_mask_i32gather_ps, _mm256_mask_i32gather_ps, _mm_mask_i64gather_ps, _mm256_mask_i64gather_ps, _mm_i32gather_epi64, _mm_mask_i32gather_epi64, _mm256_i32gather_epi64, _mm256_mask_i32gather_epi64, _mm_i64gather_epi64, _mm_mask_i64gather_epi64, _mm256_i64gather_epi64, _mm256_mask_i64gather_epi64, _mm_i32gather_epi32, _mm_mask_i32gather_epi32, _mm256_i32gather_epi32, _mm256_mask_i32gather_epi32, _mm_i64gather_epi32, _mm_mask_i64gather_epi32, _mm256_i64gather_epi32, _mm256_mask_i64gather_epi32): Surround macro parameter uses with parens.
