--- Comment #5 from liuhongt at gcc dot gnu.org --- Author: liuhongt Date: Mon Dec 9 04:16:24 2019 New Revision: 279107 URL: https://gcc.gnu.org/viewcvs?rev=279107&root=gcc&view=rev Log: Enable mask movement for VCOND_EXPR under avx512f for 128/256-bit vector when integer mask is available. Changelog gcc/ PR target/92686 * config/i386/sse.md (*<avx512>_cmp<mode>3<mask_scalar_merge_name><round_saeonly_name>, *<avx512>_cmp<mode>3<mask_scalar_merge_name>, *<avx512>_ucmp<mode>3<mask_scalar_merge_name>, *<avx512>_ucmp<mode>3<mask_scalar_merge_name>): New. * config/i386/i386.c (ix86_print_operand): New operand substitution. * config/i386/i386-expand.c (ix86_valid_mask_cmp_mode): New function. (ix86_expand_sse_cmp): Relax condition for integer mask from 512-bit vector to all 128/256/512-bit vector. Delete code gen for avx512f compare patterns since we have generic pattern now. (ix86_expand_sse_movcc): Adjust condition and codegen for maskcmp. (ix86_expand_int_sse_cmp): Don't canonicalize the comparison when corresponding vector compare is available. gcc/testsuite/ * gcc.target/i386/pr92686.inc: New file. * gcc.target/i386/avx512bw-pr92686-vpcmp-1.c: New test. * gcc.target/i386/avx512bw-pr92686-vpcmp-intelasm-1.c: Ditto. * gcc.target/i386/avx512bw-pr92686-vpcmp-2.c: Ditto. * gcc.target/i386/avx512vl-pr92686-vpcmp-1.c: Ditto. * gcc.target/i386/avx512vl-pr92686-vpcmp-intelasm-1.c: Ditto. * gcc.target/i386/avx512vl-pr92686-vpcmp-2.c: Ditto. * gcc.target/i386/avx512bw-pr92686-movcc-1.c: Ditto. * gcc.target/i386/avx512bw-pr92686-movcc-2.c: Ditto. * gcc.target/i386/avx512vl-pr92686-movcc-1.c: Ditto. * gcc.target/i386/avx512vl-pr92686-movcc-2.c: Ditto. * gcc.target/i386/avx512vl-pr88547-1.c: Adjust testcase. * gcc.target/i386/pr88547-1.c: Ditto.
