Subject: i386.md (*zero_extendsidi2): Enable alternative (?r, *Yj) also for 32bit target.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=49fe4867264fee03accf55f7dc711a9cf6926627;p=gcc.git

i386.md (*zero_extendsidi2): Enable alternative (?r, *Yj) also for 32bit target.

	* config/i386/i386.md (*zero_extendsidi2): Enable alternative (?r, *Yj)
	also for 32bit target.  Update insn attributes.
	(zero-extendsidi2 splitter): Allow all registers for operand 1.
