[PATCH] D18155: Instcombine: try to avoid wasted work in ConstantFold

[escha via llvm-commits]

escha added a comment.

What git option do I use to get a diff with full context?

If it's already folded, why does InstCombine try to optimize it? I did this under the assumption that InstCombine was doing something reasonable (and just being redundant about it); are you saying InstCombine shouldn't be doing this at all?
