It's a bit ugly to modify in-place the operands of `CI.I` and `Paired.I`. But I guess it is harmless since they will be erased soon, when the merged load instruction is created. https://github.com/llvm/llvm-project/pull/96162 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
