--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Tue Dec 18 11:22:00 2018 New Revision: 267228 URL: https://gcc.gnu.org/viewcvs?rev=267228&root=gcc&view=rev Log: PR target/88513 PR target/88514 * optabs.def (vec_pack_sbool_trunc_optab, vec_unpacks_sbool_hi_optab, vec_unpacks_sbool_lo_optab): New optabs. * optabs.c (expand_widen_pattern_expr): Use vec_unpacks_sbool_*_optab and pass additional argument if both input and target have the same scalar mode of VECTOR_BOOLEAN_TYPE_P vectors. * expr.c (expand_expr_real_2) <case VEC_PACK_TRUNC_EXPR>: Handle VECTOR_BOOLEAN_TYPE_P pack where result has the same scalar mode as the operands using vec_pack_sbool_trunc_optab. * tree-vect-stmts.c (supportable_widening_operation): Use vec_unpacks_sbool_{lo,hi}_optab for VECTOR_BOOLEAN_TYPE_P conversions where both wider_vectype and vectype have the same scalar mode. (supportable_narrowing_operation): Similarly use vec_pack_sbool_trunc_optab if narrow_vectype and vectype have the same scalar mode. * config/i386/i386.c (ix86_get_builtin) <case IX86_BUILTIN_GATHER3ALTDIV8SF>: Check for VECTOR_MODE_P rather than non-VOIDmode. * config/i386/sse.md (vec_pack_trunc_qi, vec_pack_trunc_<mode>): Remove useless ()s around "register_operand", formatting fixes. (vec_pack_sbool_trunc_qi, vec_unpacks_sbool_lo_qi, vec_unpacks_sbool_hi_qi): New expanders. * doc/md.texi (vec_pack_sbool_trunc_M, vec_unpacks_sbool_hi_M, vec_unpacks_sbool_lo_M): Document. * gcc.target/i386/avx512f-pr88513-1.c: New test. * gcc.target/i386/avx512f-pr88513-2.c: New test. * gcc.target/i386/avx512vl-pr88464-1.c: New test. * gcc.target/i386/avx512vl-pr88464-2.c: New test. * gcc.target/i386/avx512vl-pr88464-3.c: New test. * gcc.target/i386/avx512vl-pr88464-4.c: New test. * gcc.target/i386/avx512vl-pr88513-1.c: New test. * gcc.target/i386/avx512vl-pr88513-2.c: New test. * gcc.target/i386/avx512vl-pr88513-3.c: New test. * gcc.target/i386/avx512vl-pr88513-4.c: New test. * gcc.target/i386/avx512vl-pr88514-1.c: New test. * gcc.target/i386/avx512vl-pr88514-2.c: New test. * gcc.target/i386/avx512vl-pr88514-3.c: New test.
