The llvm family of code is becoming more complete in terms of a full
GNU replacement. That isn't the land of python, but you're going to
have to go outside of that anyway for actual compiler/toolchain work.
(LLVM has a builtin DWARF parser)


I'm not a fan of llvm, but the codebase does have a "not bad" design
in terms of ease of portability. Assuming your arch isn't VLIW I
wouldn't expect too much hell.


If gcc isn't a forced requirement out of the gate maybe give it a go.

Side note: there's 2 "libdwarfs" floating around.. the one from SGI
and the BSD implementation, if licensing makes any difference.. I've
worked with the later
