--- 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:3222a8493ccfec1a2e9c71103f1a693abb97cf83 commit r16-5994-g3222a8493ccfec1a2e9c71103f1a693abb97cf83 Author: Richard Biener <[email protected]> Date: Mon Dec 8 14:36:58 2025 +0100 target/121230 - x86 vector CTOR cost with 387 math The following adjusts costing of vector construction from scalars for FP modes which with 387 math can reside in FP regs which need spilling to be reloaded to XMM. I've played on the safe side with mixed SSE/387 math. PR target/121230 * config/i386/i386.cc (ix86_vector_costs::add_stmt_cost): With FP mode and 387 math cost spill/reload. * gcc.target/i386/pr121230.c: New testcase.
