ab948f4897 [interop][SwiftToCxx] ensure that buffers for heap allocated Swift values are released after parameter copy is consumed 2023-10-29 17:08:02 -07:00

39d86bc701 [interop][SwiftToCxx] the not yet implemented move constructor for Swift value types should lead to link error when a move is used in Swift, not runtime error 2023-05-07 08:55:28 -07:00

16b1fe173f [interop][SwiftToCxx] moving a Swift class in C++ performs a copy 
C++ does not have a consuming move, so fallback to copy instead

cfb3e5abae Reintroduce alwaysinline and nodebug as fallbacks to SWIFT_INLINE_THUNK_ATTRIBUTES 
If the C++ compiler doesn't support the transparent_stepping attribute,
fallback to annotating inline thunks with the alwaysinline and nodebug
attributes.

7c8523cfec Use "transparent_stepping" attribute in C++ compiler generated interop 
Use transparent_stepping instead of nodebug and alwaysinline in compiler
generated C++ code from Swift. This attribute allow for annotated
functions to be used in expression evaluation, which is an advantage
over the former two.

94c1de7611 [interop][SwiftToCxx] use 'SWIFT_INLINE_PRIVATE_HELPER' macro for static returnNewValue functions to ensure attribute(used) isn't applied to them 2023-03-15 09:13:38 -07:00

eeaba69df0 [interop][SwiftToCxx] use 'nodebug' instead of articial for interop thunks 
a combination of always_inline and nodebug allows LLDB to skip over thunks

3948a2a5d3 [interop][SwiftToCxx] annotate inline thunks with SWIFT_INLINE_THUNK 
This macro applies always_inline in addition to inline. It also applies artificial, which lets debugger know that this is an artificial function. The used attribute is added in debug builds to ensure that the symbol is emitted in the binary so that LLDB can invoke it.

f4e7e1c53e [interop][SwiftToCxx] update external_source_symbol check for USR clause following Clang changes 2023-02-07 14:51:33 -08:00
Alex Lorenz
3b3d6c825a [interop][SwiftToCxx] Annotate emitted declarations with Clang's external_source_symbol attribute 
Each emitted declaration is annotated with the external_source_symbol with its own USR, to allow Clang's indexer to recognize this declaration as a Swift declaration with a specific USR

a24ebeaa51 [interop][SwiftToCxx] install _SwiftCxxInteroperability.h header as part of compiler build, not stdlib 
The _SwiftCxxInteroperability.h is too tightly coupled to the compiler right now and should not be shipped with the standard library. In the future it could be moved back to the standard library.
