--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by hongtao Liu <liuho...@gcc.gnu.org>: https://gcc.gnu.org/g:872da9a6f664a06d73c987aa0cb2e5b830158a10 commit r12-2549-g872da9a6f664a06d73c987aa0cb2e5b830158a10 Author: liuhongt <hongtao....@intel.com> Date: Fri Mar 26 10:56:47 2021 +0800 Add the member integer_to_sse to processor_cost as a cost simulation for movd/pinsrd. It will be used to calculate the cost of vec_construct. gcc/ChangeLog: PR target/99881 * config/i386/i386.h (processor_costs): Add new member integer_to_sse. * config/i386/x86-tune-costs.h (ix86_size_cost, i386_cost, i486_cost, pentium_cost, lakemont_cost, pentiumpro_cost, geode_cost, k6_cost, athlon_cost, k8_cost, amdfam10_cost, bdver_cost, znver1_cost, znver2_cost, znver3_cost, btver1_cost, btver2_cost, btver3_cost, pentium4_cost, nocona_cost, atom_cost, atom_cost, slm_cost, intel_cost, generic_cost, core_cost): Initialize integer_to_sse same value as sse_op. (skylake_cost): Initialize integer_to_sse twice as much as sse_op. * config/i386/i386.c (ix86_builtin_vectorization_cost): Use integer_to_sse instead of sse_op to calculate the cost of vec_construct. gcc/testsuite/ChangeLog: PR target/99881 * gcc.target/i386/pr99881.c: New test.
