--- Comment #11 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So I tried a simplier patch to fix this by marking both v30 and v29 as not
canidates but the problem is still there is some shifting of the fpr_candidates
going on which confuses things after the marking happens. Dealing with the
merging of the canidates; I think merge_fpr_info .

Going back to my other patch and seeing if I can fix up the SME issue.
