Rintaro Ishizaki	9c9010e5b7	[CMake] Support Macros in Linux ... For compiling codes required for macro support, we now need swiftc compiler in the build machine. Unlike Darwin OSes, where swiftCore runtime is guaranteed to be present in /usr/lib, Linux doesn't have ABI stability and the stdlib of the build machine is not at the specific location. So the built compiler cannot relies on the shared object in the toolchain.	2023-08-24 17:04:15 +00:00
Rintaro Ishizaki	d28e1c963c	[CMake] Fix swift_supports_implicit_module failure ... swift_supports_implicit_module invokes /path/to/toolchain/usr/bin/swiftc directly without using `xcrun`. That fails to set necessary environmental variables to make swiftc infer the SDK path. Because of that swift_supports_implicit_module used to fail because the test compilation fails to load the stdlib. This PR workaround it by passing `-parse-stdlib` to avoid implicit stdlib loading.	2023-03-16 16:13:50 -07:00
Alastair Houghton	44783e72c6	[Frontend] Add support for implicit import of _Backtracing ... Once the API has gone through Swift Evolution, we will want to implicitly import the _Backtracing module. Add code to do that, but set it to off by default for now. rdar://105394140	2023-03-04 08:00:06 +00:00
