Subject: [RS6000] vsx_extract_v4sf
Date: Mon, 01 Jun 2015 06:27:00 -0000	[thread overview]
Message-ID: <20150601062718.GT14752@bubble.grove.modra.org> (raw)

Found today when deleting "S" constraint, unused after a local patch.
rs6000/vsx.md:1867: error: undefined machine-specific constraint at this point: "Sa>,<VSa>"
That can't be good says I.  An over-enthusiastic search and replace
by the look of it.  Bootstrapped and regression tested
powerpc64le-linux.  OK for mainline and gcc-5 branch?

	* config/rs6000/vsx.md (vsx_extract_v4sf): Revert accidental
	2014-08-11 change.
