CallGraph visited LambdaExpr by getting the Call Operator from CXXRecordDecl (LambdaExpr::getCallOperator calls CXXRecordDecl::getLambdaCallOperator), which replaced generic lambda call operators with the non-instantiated FunctionDecl. The result was that the CallGraph would only pick up non-dependent calls. This patch does a few things: 1- Extend CXXRecordDecl to have a getDependentLambdaCallOperator, which will get the FunctionTemplateDecl, rather than immediately getting the TemplateDecl. 2- Define getLambdaCallOperator and getDependentLambdaCallOperator in terms of a common function. 3- Extend LambdaExpr with a getDependentCallOperator, which just calls the above function. 4- Changes CallGraph to handle Generic LambdaExprs. llvm-svn: 373247
