[Louis Dionne via Phabricator via cfe-commits]

ldionne added inline comments.


================
Comment at: clang/lib/Frontend/InitPreprocessor.cpp:1127
 
+  if (LangOpts.RelativeCXXABIVTables)
+    Builder.defineMacro("__RELATIVE_CXX_ABI_VTABLES");
----------------
Should we be using some `__has_feature(...)` instead?
