If I understood correctly, what you're trying to do here is to apply an icmp fold early before the sext -> zext information gets lost. I don't think this is the correct way to approach the problem. The correct way is to preserve the fact that the operand is non-negative when converting to zext, which would allow the InstCombine fold to reliably undo this. In fact, there is a pending patch for this at https://reviews.llvm.org/D156444. https://github.com/llvm/llvm-project/pull/67594 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
