[PATCH] D43759: [SCEV] Smarter logic in computeConstantDifference

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev added inline comments.


================
Comment at: lib/Analysis/ScalarEvolution.cpp:9805
 
   Optional<APInt> Addend = computeConstantDifference(LHS, FoundLHS);
   if (!Addend)
----------------
This is incorrect. LHS and FoundLHS can have different types. I will fix this before merging this patch.
