Subject: 	PR target/17626
X-Git-Url: http://git.sourceforge.jp/view?p=pf3gnuchains%2Fgcc-fork.git;a=commitdiff_plain;h=24e179d2815df23db744e4393308e9afb83bd932

	PR target/17626
	* config/cris/cris.md (moverside, movemside): Rename variable
	"reg" to "otherop".  To generate canonical RTX, check that otherop
	isn't constant instead of checking that operand 1 is a register.
