Name matching functions

[linuswagner]

When I extract function and method names from the AST, I want to match them to their corresponding logical names in the M3.

The M3 includes the structure of the arguments in the name. It would be nice to have somewhere a "full name to argument-less" relation. Looks like cFunctionsToNoArgs could do something like that, but on my C++ code, there's no difference.

The decl keyword field on AST nodes is supposed to provide this match. It's of type loc and on declarations tells us what the resolved qualified name is of the declared artifact. On expressions and other names in statements it annotates uses of names with the resolved qualified URI.
