Feel free to ignore: probably worth adding test for smth like ``` void *ptr4 = __builtin_ptrauth_sign_constant(&external, 0, NULL); ``` This doesn't bring that much value over testing a non-null constant integer discriminator, but: 1. In docs, having null pointer as a discriminator is listed as a separate option > This is a constant expression if the extra data is an integer or null pointer constant. 2. With `NULL` defined as `#define NULL ((void*) 0)`, we'll explicitly test having a constant pointer, not an integer, value as a discriminator https://github.com/llvm/llvm-project/pull/93904 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
