[PATCH] D46049: [OpenCL] Add constant address space to __func__ in AST

[Anastasia Stulova via Phabricator via cfe-commits]

Anastasia added inline comments.


================
Comment at: lib/AST/Expr.cpp:870
+  if (C.getLangOpts().OpenCL && Ty.getAddressSpace() == LangAS::Default)
+    Ty = C.getAddrSpaceQualType(Ty, LangAS::opencl_constant);
+

Indeed for the current cases it doesn't... there might be some uncaught ones though where it can be useful. But we can add it later as well. So I am thinking to undo this?
