Commit Message

H.J. Lu Feb. 18, 2019, 6:36 p.m. UTC

Emulate MMX vec_dupv2si with SSE.  Add the "Yw" constraint to allow
broadcast from integer register for AVX512BW with TARGET_AVX512VL.
Only SSE register source operand is allowed.

	PR target/89021
	* config/i386/constraints.md (Yw): New constraint.
	* config/i386/mmx.md (*vec_dupv2si): Changed to
	define_insn_and_split and also allow TARGET_MMX_WITH_SSE to
	support SSE emulation.
