I don't know if it's important for CHERI to have this or if the IR-level optimisations render it not so needed. But `NULL + int` is how we represent an integer as a pointer, so `NULL + x + y` is something that can legitimately turn up, and we want to be able to fold the x and y together as just integer arithmetic, only converting to a capability at the very end when needed. https://github.com/llvm/llvm-project/pull/142739 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
