leonardchan added a project: clang.

If an `address_space` attribute is defined in a macro, print the macro instead when diagnosing a warning or error for incompatible pointers with different address_spaces.

Originally started from http://lists.llvm.org/pipermail/cfe-dev/2018-August/058702.html where the original proposal was a new pragma, but instead just changing the way `address_space` gets printed in a diagnostic.
