Lu <[email protected]>: https://gcc.gnu.org/g:f9056eb2213666feca4f81e6fc2af22c70a05d8b commit r17-3455-gf9056eb2213666feca4f81e6fc2af22c70a05d8b Author: H.J. Lu <[email protected]> Date: Thu Aug 20 10:29:41 2026 +0800 x86: Compile vect-shiftv[48]qi.c with -mno-ssse3 -mtune=generic Compile vect-shiftv[48]qi.c with -mno-ssse3 -mtune=generic to avoid FAIL: gcc.target/i386/vect-shiftv4qi.c scan-assembler-times psllw 2 FAIL: gcc.target/i386/vect-shiftv4qi.c scan-assembler-times psrlw 5 FAIL: gcc.target/i386/vect-shiftv8qi.c scan-assembler-times psllw 2 FAIL: gcc.target/i386/vect-shiftv8qi.c scan-assembler-times psrlw 5 due to SSSE3/SSE4 instructions and different code sequences when SSSE3 is enabled by default and a different default cost mode is in use. PR testsuite/126923 * gcc.target/i386/vect-shiftv4qi.c (dg-options): Replace "-mno-avx2 -mno-avx512vl" with "-mno-ssse3 -mtune=generic". * gcc.target/i386/vect-shiftv8qi.c (dg-options): Likewise.
