[PATCH] D26934: [libc++] Add _LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS

[Eric Fiselier via cfe-commits]

EricWF added a comment.

There are two usages of `_LIBCPP_DISABLE_DLL_IMPORT_EXPORT` in `CMakeLists.txt` and `__config_site.in` that need to be changed as well.

Also what about users of the existing name `_LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS`? Should we #error to inform them of the change or should we automatically translate it to the new name for them?
