--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Thu Jun 27 11:13:10 2019 New Revision: 272745 URL: https://gcc.gnu.org/viewcvs?rev=272745&root=gcc&view=rev Log: PR target/90991 * config/i386/sse.md (avx_vec_concat<mode>): Use nonimmediate_operand instead of register_operand for operands[1], add m to its constraints if operands[2] uses "C" constraint. Ensure in condition that if operands[2] is not 0, then operands[1] is not a MEM. For last two alternatives, use unaligned loads instead of aligned if operands[1] is misaligned_operand. * gcc.target/i386/avx2-pr90991-1.c: New test. * gcc.target/i386/avx512dq-pr90991-2.c: New test.
