[PATCH 28/40] i386: Emulate MMX ssse3_phdv2si3 with SSE

2019-02-14 Thread H.J. Lu
Emulate MMX ssse3_phdv2si3 with SSE by moving bits 64:95 to bits 32:63 in SSE register. Only SSE register source operand is allowed. PR target/89021 * config/i386/sse.md (ssse3_phdv2si3): Changed to define_insn_and_split to support SSE emulation. --- gcc/config/i386/sse.m
