[cfe-dev] Dynamically adding a new FunctionDecl to the AST

[Dillon Sharlet]

Hello,

I'm attempting to construct a new function in the course of parsing the
AST. I've got it mostly working, except the function I've generated only
gets emitted as a declaration in LLVM, not a definition. I'm attempting to
figure out where in the template instanatiation logic the function gets
added to the AST for code gen, but I haven't been able to find it.

If I create a new function, how do I get it to be emitted in the AST
consumer? I've copied just about all of the logic that I can from
TemplateDeclInstantiator::VisitFunctionDecl
(which does basically the same thing I'm doing, adds a dynamically
generated FunctionDecl to the AST) without much luck.

Thanks for any advice!

Dillon
