Subject: i386.md ("isa" attribute): Add sse_noavx.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=37d8d439f2ab41a5edad09774f122d58730b26b3;p=gcc.git

i386.md ("isa" attribute): Add sse_noavx.

	* config/i386/i386.md ("isa" attribute): Add sse_noavx.
	("enabled" attribute): Handle sse_noavx isa attribute.
	* config/i386/mmx.md (*vec_dupv2sf): Add "isa" attribute.
	Use TARGET_SSE && SSE_REGNO_P in split condition.
	(*vec_dupv2sf): Ditto.
