[Nico Weber via Phabricator via cfe-commits]

thakis added inline comments.


================
Comment at: clang/lib/Lex/PPMacroExpansion.cpp:1713
               // FIXME: This is inconsistent; we usually suggest detecting
               // builtin macros via #ifdef. Don't add more cases here.
               .Case("__is_target_arch", true)
----------------
(I saw this comment, but system headers force our hand.)
