[PATCH] D150966: [clang] Don't define predefined macros multiple times

[Sergei Barannikov via Phabricator via cfe-commits]

barannikov88 added a comment.

Is it possible/worth to add an assertion to Builder.defineMacro to enforce this one definition rule?



================
Comment at: clang/lib/Frontend/InitPreprocessor.cpp:1305
+    Builder.defineMacro("__ELF__");
+  }
+
----------------
Redundant braces.
