From: Hongyu Wang <hongyuw@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r12-8174] i386: Correct target attribute for crc32 intrinsics Date: Fri, 15 Apr 2022 12:19:32 +0000 (GMT) [thread overview] Message-ID: <20220415121932.4A8943857378@sourceware.org> (raw) https://gcc.gnu.org/g:a335a94a1bf49dcb3c966af05cd68be6ee36277e commit r12-8174-ga335a94a1bf49dcb3c966af05cd68be6ee36277e Author: Hongyu Wang <hongyu.wang@intel.com> Date: Fri Apr 15 10:51:06 2022 +0800 i386: Correct target attribute for crc32 intrinsics Complile _mm_crc32_u8/16/32/64 intrinsics with -mcrc32 would meet target specific option mismatch. Correct target pragma to fix. gcc/ChangeLog: * config/i386/smmintrin.h: Correct target pragma from sse4.1 and sse4.2 to crc32 for crc32 intrinsics. gcc/testsuite/ChangeLog: * gcc.target/i386/crc32-6.c: Adjust dg-error message. * gcc.target/i386/crc32-7.c: New test.
