[cfe-dev] Rewriter: How to rewrite an empty function argument list?

[Alex L via cfe-dev]

Hi Marcel,

I believe that you can get the location of '('/')' and insert a new
parameter after/before that location. The locations of braces should be in
the FunctionTypeLoc which you can extract from the TypeLoc value returned
by calling ((FunctionDecl *)YourFunction)->getTypeSourceInfo->getTypeLoc();
