Maybe one of CDI/DQI/BWI/VLX is somewhat broken on 3.8? Which is why I said "or any subvariant" ;-). ERI, CDI, PFI, DQI, BWI, VLX are all avx512 variants (omg naming???), though that skylake in the llvm 3.8 list doesn't suport ERI and PFI. I'm not sure, but probably dropping avx512 manually when a enhanced variant still gets enabled won't do anything. I don't think PKU would matter (but no guarantee...). I suppose we should explicitly disable all of them via mattrs too (not that it's a battle we can win, there will be some extensions at some point...).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
