[X86][Driver] Do not add `-evex512` for `-march=native` when the target doesn't support AVX512 (#91694) This prevents problems with ports that fail to build with CPUTYPE=native, if the native CPU supports AVX512F, resulting in errors like: /wrkdirs/usr/ports/archivers/libdeflate/work/libdeflate-1.20/lib/x86/adler32_template.h:197:21: error: always_inline function '_mm512_set1_epi8' requires target feature 'evex512', but would be inlined into function 'adler32_x86_avx512_vl512_vnni' that is compiled without support for 'evex512' 197 | const vec_t ones = VSET1_8(1); | ^ /wrkdirs/usr/ports/archivers/libdeflate/work/libdeflate-1.20/lib/x86/adler32_template.h:116:23: note: expanded from macro 'VSET1_8' 116 | # define VSET1_8(a) _mm512_set1_epi8(a) | ^ /wrkdirs/usr/ports/archivers/libdeflate/work/libdeflate-1.20/lib/x86/adler32_template.h:197:21: error: AVX vector return of type '__m512i' (vector of 8 'long long' values) without 'evex512' enabled changes the ABI /wrkdirs/usr/ports/archivers/libdeflate/work/libdeflate-1.20/lib/x86/adler32_template.h:116:23: note: expanded from macro 'VSET1_8' 116 | # define VSET1_8(a) _mm512_set1_epi8(a) | ^ Ports known to be affected are: archivers/libdeflate, devel/highway, www/node20, and lang/rust. (For rust itself there is also a similar issue reported at https://github.com/rust-lang/rust/pull/121088). PR: 276104 Reported by: netchild MFC after: 3 days |
