[David Chisnall via Phabricator via cfe-commits]

theraven added inline comments.


================
Comment at: lib/CodeGen/CGBlocks.cpp:163
+  std::string TypeAtEncoding =
+      CGM.getContext().getObjCEncodingForBlock(BlockInfo.getBlockExpr());
+  Name += "e" + llvm::to_string(TypeAtEncoding.size()) + "_" + TypeAtEncoding;
----------------
Specifically, this line.  It is unsafe to use an Objective-C encoding directly as a symbol name on ELF.
