[PATCH] D136712: Define _GNU_SOURCE for arm baremetal in C++ mode.

[Tom Hughes via Phabricator via cfe-commits]

tomhughes added inline comments.


================
Comment at: clang/lib/Basic/Targets/ARM.cpp:697-698
     Builder.defineMacro("__ELF__");
+    if (Opts.CPlusPlus)
+      Builder.defineMacro("_GNU_SOURCE");
+  }
----------------
I think this should apply to both C and C++
