--- Comment #18 from hjl at gcc dot gnu.org <hjl at gcc dot gnu.org> --- Author: hjl Date: Tue Jan 5 20:17:26 2016 New Revision: 232087 URL: https://gcc.gnu.org/viewcvs?rev=232087&root=gcc&view=rev Log: Add vector_memory_operand and "Bm" constraint SSE vector arithmetic and logic instructions only accept aligned memory operand. This patch adds vector_memory_operand and "Bm" constraint for aligned SSE memory operand. They are applied to SSE plusminus and any_logic patterns. gcc/ PR target/68991 * config/i386/constraints.md (Bm): New constraint. * config/i386/predicates.md (vector_memory_operand): New predicate. * config/i386/sse.md: Replace xm with xBm in plusminus and any_logic patterns. gcc/testsuite/ PR target/68991 * g++.dg/pr68991-1.C: New test. * g++.dg/pr68991-2.C: Likewise.
