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
