Author: smeenai Date: Mon Dec 5 13:42:11 2016 New Revision: 288692 URL: http://llvm.org/viewvc/llvm-project?rev=288692&view=rev Log: [libc++abi] Add _LIBCXXABI_DISABLE_VISIBILITY_ANNOTATIONS
It's useful to be able to disable visibility annotations entirely; for example, if we're building libc++abi static to include in another library, and we don't want any libc++abi functions getting exported out of that library. This is a generalization of _LIBCXXABI_DISABLE_DLL_IMPORT_EXPORT.
