[cfe-dev] Constructor Initializers

[Jordan Rose]

I don't know for sure, but my guess is that the constructors declared within the CXXRecordDecl are just declarations, and the out-of-line definitions aren't showing up. You'll need to use hasBody() (on FunctionDecl) to get the particular CXXConstructorDecl that has the initializers.

(Yes, there's no getDefinition(). The predicate hasBody() has to do a search for the definition anyway, so it just returns the FunctionDecl representing the definition in an optional out parameter.)

Hope that helps,
Jordan
