--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Thu Mar 30 13:29:28 2017 New Revision: 246588 URL: https://gcc.gnu.org/viewcvs?rev=246588&root=gcc&view=rev Log: PR target/80206 * config/i386/sse.md (<extract_type>_vextract<shuffletype><extract_suf>_mask): Use register as dest whenever it is a MEM not rtx_equal_p to the corresponding dup operand, and when forcing into reg move the reg into the memory afterwards. (<extract_type_2>_vextract<shuffletype><extract_suf_2>_mask): Likewise. Use <ssehalfvecmode> instead of <ssequartermode> for the force_reg mode. (avx512vl_vextractf128<mode>): Use register as dest either always when a MEM, or when it is a MEM not rtx_equal_p to the corresponding dup operand, or even not when it is a CONST_VECTOR depending on the mode and lo vs. hi. (avx512dq_vextract<shuffletype>64x2_1_maskm): Remove extraneous parens. (avx512f_vextract<shuffletype>32x4_1_maskm): Likewise. (<mask_codefor>avx512dq_vextract<shuffletype>64x2_1<mask_name>): Likewise. Require that operands[2] is even. (<mask_codefor>avx512f_vextract<shuffletype>32x4_1<mask_name>): Remove extraneous parens. Require that operands[2] is a multiple of 4. (vec_extract_lo_<mode><mask_name>): Don't bother testing if operands[0] is a MEM if <mask_applied>, the predicates/constraints disallow memory then. * gcc.target/i386/pr80206.c: New test. Added: trunk/gcc/testsuite/gcc.target/i386/pr80206.c Modified: trunk/gcc/ChangeLog trunk/gcc/config/i386/sse.md trunk/gcc/testsuite/ChangeLog
