tocarip.intel at gmail dot com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |tocarip.intel at gmail dot com --- Comment #2 from tocarip.intel at gmail dot com --- Created attachment 34346 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=34346&action=edit Proposed patch. Added (untested patch) allows k{or,xoer,...} for avx512vbmi case, and fixes this problem. However I'm not sure, that just enabling whole avx512bw isn't a better idea.
