New Revision: 42150
URL: http://llvm.org/viewvc/llvm-project?rev=42150&view=rev
Log:
Moved GraphTraits<Stmt*> to StmtGraphTraits.h. This allows consumers of Stmt.h not to have to pay the cost
of parsing the GraphTraits templates if they don't need that functionality.
Defined nodes_iterator for GraphTraits<Stmt*> to be based on llvm::df_iterator.
