We are planning to consume this downstream in the Swift compiler for C++ interop. Swift has non-escapable types, like Swift's `Span` type. The interop layer cannot bridge a C++ `std::span` as Swift's `Span` without this additional information from the API's authors. The need to annotate this property was also raised in https://discourse.llvm.org/t/rfc-a-clangir-based-safe-c/83245 which was the main motivation to make this change upstream, to avoid having multiple different spellings across the parallel efforts to interoperate between safe and unsafe code. https://github.com/llvm/llvm-project/pull/117344 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
