[PATCH] D17884: Disallow duplication of imported entities

[don hinton via llvm-commits]

hintonda added a comment.

It's an instance of the X Macro technique.  In this case:

lib/IR/LLVMContextImp.h: 937
#define HANDLE_MDNODE_LEAF_UNIQUABLE(CLASS)                                    \

  DenseSet<CLASS *, CLASS##Info> CLASS##s;

#include "llvm/IR/Metadata.def"

include/llvm/IR/Metadata.def: 110
HANDLE_SPECIALIZED_MDNODE_LEAF_UNIQUABLE(DIImportedEntity)
