--- Comment #9 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:3c5d49a2f046e223c32d44719999d253db0ea0bb commit r17-439-g3c5d49a2f046e223c32d44719999d253db0ea0bb Author: Richard Biener <[email protected]> Date: Wed May 6 13:43:27 2026 +0200 adjust OMP SIMD call cost The following adds special handling to OMP SIMD vector call costs which were not costed at all and for which a single simple vector stmt isn't appropriate. PR125174 shows that even when AVX imposes more overhead (from also slightly bogus costing) than SSE, when there's two OMP SIMD calls involved doing less of those should trump that. PR target/125174 * config/i386/i386.cc (ix86_vector_costs::add_stmt_cost): Cost calls as 10 times FMA.
