Let's add a comment explaining that we need that because of Apple's fork so people unaware of the problem would know why such checks are needed. The comment might look like this: ``` // In Apple's fork of clang, `__ptrauth` qualifier can be only applied to // pointer types, and `__ptrauth_restricted_intptr` is used instead for // integer types. In mainline clang, we only have `__ptrauth` which could // be applied both to pointer and integer types. // These helper macros allow seemless build of runtime libraries with // Apple's fork of clang. // TODO: If/when Apple's clang switches to mainline way of using // `__ptrauth` qualifier, get rid of these conditionals. ``` https://github.com/llvm/llvm-project/pull/143230 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
