X-Git-Tag: basepoints/gcc-16~7599
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=aae535f3a870659d1f002f82bd585de0bcec7905;p=thirdparty%2Fgcc.git

i386: Swap compare operands in ustrunc patterns

A last minute change led to a wrong operand order in the compare insn.

gcc/ChangeLog:

	* config/i386/i386.md (ustruncdi<mode>2): Swap compare operands.
	(ustruncsi<mode>2): Ditto.
	(ustrunchiqi2): Ditto.
