[cfe-dev] __APPLE_CC__ macro

[Robinson, Paul]

Questions about Apple products should be asked on an Apple forum.  Sorry, this isn't the right place to ask.

Subject: [cfe-dev] __APPLE_CC__ macro

Can someone explain the usefulness of __APPLE_CC__? The documentation claims [the] macro is set to an integer that represents the version number of the compiler.

But one version of Apple clang defines:


#define __APPLE_CC__ 6000

#define __apple_build_version__ 6020053

#define __clang_version__ "6.1.0 (clang-602.0.53)"


And another newer version of Apple clang defines:
#define __APPLE_CC__ 6000
#define __apple_build_version__ 7000053
#define __clang_version__ "7.0.0 (clang-700.0.53.3)"

So how does __APPLE_CC__ represent the "version" of the compiler? Is it stuck at 6000 now forever?
