[PATCH] D47023: Limit the number of phis in intptr/ptrint folding

[David Li via Phabricator via llvm-commits]

davidxl added a comment.

My profile shows that with the 20000 phi case, the cycles are cut in half
with the limit.

The remaining problem is in : [.] llvm::BasicBlock::getFirstNonPHI

I guess a short fix would be to have a customized version of getFirstNonPhi
which returns an 'end' if the limit is reached.  You can try if that works
for you.

thanks,

David
