[cfe-dev] Getting the pointer to an out-of-class VarDecl

[Mihai Draghicioiu]

Hi guys. I'm trying to get a pointer to the last VarDecl from the first
VarDecl, so I can access the initialization Expr. As you can see below,
There are two VarDecls, and I'd like to get a pointer to the out-of-class
one. Also, I can't figure out how the second VarDecl gets its parent
pointer.

I just hope I don't have to recurse the AST again each time.

class Foo {
	static int poop;};
int Foo::poop = 3;


TranslationUnitDecl 0x4b6b060 <<invalid sloc>> <invalid sloc>
|-TypedefDecl 0x4b6b5a0 <<invalid sloc>> <invalid sloc> implicit
__int128_t '__int128'
|-TypedefDecl 0x4b6b600 <<invalid sloc>> <invalid sloc> implicit
__uint128_t 'unsigned __int128'
|-TypedefDecl 0x4b6b9c0 <<invalid sloc>> <invalid sloc> implicit
__builtin_va_list '__va_list_tag [1]'
