[PATCH] D143766: [InstCombine][WIP] Fix InstCombinerImpl::foldICmpMulConstant for nsw and nuw mul with unsigned compare.

[Noah Goldstein via Phabricator via llvm-commits]

goldstein.w.n added inline comments.


================
Comment at: llvm/lib/Transforms/InstCombine/InstCombineCompares.cpp:2071
     // MININT / -1 --> overflow.
     if (C.isMinSignedValue() && MulC->isAllOnes())
       return nullptr;
----------------
is this needed? Seems redundant given the nsw flag.
