Subject: 	* config/i386/i386.md (*ashl<mode>3_mask): Change operand 2 preticate
X-Git-Tag: upstream/4.9.2~26180
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=be2c9808eca2ed57ec00becba2e4d2a38a7c50ad;p=platform%2Fupstream%2Flinaro-gcc.git

	* config/i386/i386.md (*ashl<mode>3_mask): Change operand 2 preticate
	to nonimmediate_operand.  Force operand 2 to register when allowed.
	(*<shiftrt_insn><mode>3_mask): Ditto.
	(*<rotate_insn><mode>3_mask): Ditto.
