[cfe-dev] Clang Semantic Analysis for Beginner

[Jeffrey Morgan]

Hi,

I'm looking for resources or advice on how to get started with adding to a
type system for a C like language in clang.

For example, if I had the following function declarations (where matrix is
a type I added into c++):

void Foo(matrix);
void Foo(float);


1) How would I teach clang about overloading the Foo function to take the
correct types.

2) I see a SemaConsumer class that seems to work like the ASTConsumer, but
allows me to modify the AST.  If I was implementing a type system (or
additions to one), would I work mostly with this class?

Thanks, I've google for information but I oculdn't find much.

I appreciate your time/knowledge.

Thanks!

Jeff
