Subject: Minor fixup to the sparc bshuffle pattern.
X-Git-Tag: releases/gcc-4.7.0~3408
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4f936a37f29b67f34b7dc8b8021025662a171426;p=thirdparty%2Fgcc.git

Minor fixup to the sparc bshuffle pattern.

	* config/sparc/sparc.md (bshuffle<V64I:mode>_vis): Don't wrap GSR_REG in
	a USE, since it's now a true arg to the UNSPEC.
