--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I did not know whether it is implementable (in VSX or in Altivec) for 32-bit targets etc., all I was suggesting was what to do if it is not implementable. If it is implementable, somebody familiar with VSX/Altivec should add the implementation, or we can temporarily use the patch that has been posted and get back to it later. Or if it is partly implementable (e.g. can be done in VSX and can't be done in Altivec, etc.), then the patch can still be used after amendments for what will and what will not work. Right now it is a P1 blocker because we ICE on something that worked perfectly fine (perhaps slower than it could) in GCC 10. So something needs to be done before GCC 11 and we have ~ a month left for that.
