Event TimelineComment Actions I thin this patch does too many changes at the same time. Can we separate support for the zero pattern from the recursive mask recognition? goldstein.w.n retitled this revision from [InstCombine] Improve scope of `foldICmpWithLowBitMaskedVal` to [InstCombine] Improve mask detection in `foldICmpWithLowBitMaskedVal`.Thu, Aug 31, 6:33 PM
