I noticed, that the patches add a SI_SPILL_V96 instruction and while all others are added to getNumSubRegsForSpillOp() as well as SIInstrInfo::expandPostRAPseudo(), both in lib/Target/R600/SIInstrInfo.cpp, I don't see the V96 case covered. Is this an oversight or am I missing something (entirely possible, since my LLVM knowledge is very limited)? I just thought I bring it up, in case that's something you'd like to fix before pushing it out. > Thanks for tracking this down.

I will try to look at this on Monday. I'm glad I could help. If you know of a specific game, maybe ping me privately and if I have it, I'm willing to test those as well. >> P.S.: Any idea, when the si-spill-fixes branch is going to land upstream? >> > > As soon as I can verify that it is working. Ok, fair enough. ;-) (Just wanted to know how long I've to keep building LLVM myself :-p) Cheers, Kai -- Kai Wasserbäch (Kai Wasserbaech) E-Mail: k...@dev.carbon-project.org
