[LLVMdev] function overload in C

[Alireza Moshtaghi]

Hi,
I'm trying to implement an overloading behavior to some of our builtin functions, and came across the following comment in SemaExpr.cpp

// Check for overloaded calls. This can happen even in C due to extensions.
If (Fn->getType() == Context.OverloadTy) { ....

I was wondering which C extensions is this referring to?

Thanks
Ali
