[cfe-dev] How to change calling convention.

I tried creating a copy of the type using the copy constructor of FunctionType but that just gave me a bunch of compile errors about the Type constructor being private. Then I wanted to change the calling convention of that copied type and call setType. I'm currently trying to construct a new FunctionType using get methods on the previous type to fill in the parts that remain constant. The problem at the moment is that isVariadic() seems to be private but I presume that function types cannot be Variadic so I'll just pass false there and then try setType.
What I'm trying to do is add pragmas that control the default calling convention. If there is a way to do this all within the Lexer rather than changing it afterwards I'm all ears.

Types are immutable, but FunctionDecl's do have a setType method.

What are you trying to do?
