Agreed. Effectively for a target independent pass, we can say a pointer kernel argument has to be in AS X w/o having a dedicated pass for that. This is currently done in https://github.com/llvm/llvm-project/pull/137488. However, when it comes to an indirection, it can't be handled in a target independent way. We can't really fully remove this pass at the moment. https://github.com/llvm/llvm-project/pull/137655 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
