[shims/Visibility.h](https://github.com/swiftlang/swift/blob/main/stdlib/public/SwiftShims/swift/shims/Visibility.h#L137) uses `__MACH__` to figure out how to configure the visibility attributes. It's taking `__MACH__` to mean Mach-O and not dyld. Without that, apple-none-macho falls down to Windows declspec which is an error. libc++'s [__configuration/platform.h](https://github.com/llvm/llvm-project/blob/main/libcxx/include/__configuration/platform.h#L21) takes the same meaning. usr/include/TargetConditionals.h also equates `__MACH__` to Mach-O. https://github.com/llvm/llvm-project/pull/120507 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
