This patch fixes the wrong constraint (o instead of wY) for a STXSD instruction on a vector extract operation that is optimizd to do a store if the element being extracted is in the right position. I have built a compiler with/with out the patch on a little endian power8 system. The runs finished with no regressions. Can I check it into trunk?
