Since the interger vector construction cost has changed, we need to adjust the load and store costs for intel processers. With the patch applied 538.imagic_r:gets ~6% improvement on ADL for multicopy. 525.x264_r :gets ~2% improvement on ADL and ICX for multicopy. with no measurable changes for other benchmarks. gcc/ChangeLog PR target/105493 * config/i386/x86-tune-costs.h (skylake_cost): Raise the gpr load cost from 4 to 6 and gpr store cost from 6 to 8. Change SSE loads and unaligned loads cost from {6, 6, 6, 10, 20} to {8, 8, 8, 8, 16}. (icelake_cost): Ditto. (alderlake_cost): Raise the gpr store cost from 6 to 8 and SSE loads, stores and unaligned stores cost from {6, 6, 6, 10, 15} to {8, 8, 8, 10, 15}. gcc/testsuite/ PR target/105493 * gcc.target/i386/pr91446.c: Adjust to expect vectorization * gcc.target/i386/pr99881.c: XFAIL. * gcc.target/i386/pr105493.c: New. * g++.target/i386/pr105638.C: Use other sequence checks instead of vpxor, because code generation changed.
