[PATCH 19/41] i386: Emulate MMX mmx_pmovmskb with SSE

2019-02-18 Thread H.J. Lu

Emulate MMX mmx_pmovmskb with SSE by zero-extending result of SSE pmovmskb from QImode to SImode. Only SSE register source operand is allowed. PR target/89021 * config/i386/mmx.md (mmx_pmovmskb): Changed to define_insn_and_split to support SSE emulation. --- gcc/config/i3
