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?
