We already do similar things with vector instructions and several intrinsics. https://github.com/llvm/llvm-project/pull/131287 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
