Alex Lorenz	4c9582c295	Revert "Merge pull request #41831 from hyp/unify-header" ... This reverts commit cd93d23bac, reversing changes made to f9f5476e9a.	2022-03-18 10:03:07 -07:00
Alex Lorenz	9d52099d5b	[cxx-interop] start to emitting a unified header file for a Swift module ... This change removes the -emit-cxx-header option, and adds a new -emit-clang-header-path option instead. It's aliased to -emit-objc-header-path for now, but in the future, -emit-objc-header-path will alias to it. After this change Swift can start emitting a single header file that can be expose declarations to C, Objective-C, or C++. For now C++ interface is generated (for all public decls) only when -enable-cxx-interop flag is passed, but that behavior will change once attribute is supported.	2022-03-17 10:34:47 -07:00
Alex Lorenz	858a847d27	[cxx-interop] use SWIFT_NOEXCEPT for Swift function prototypes ... This will allow these functions to be used from C. Also add a static_assert to verify that noexcept is actually used.	2022-03-13 11:08:32 -07:00
