Yes, it is just a bit obscure:

(top-gdb) python f = gdb.selected_frame()
(top-gdb) python print f.find_sal().symtab.filename
../../archer/gdb/gdb.c

I am curious to know more about what you are trying to do.

On the archer branch we still have a reimplementation of "backtrace"
that lets 3rd parties plug in filters.  This is not fully baked yet (we
know of some design flaws pointed out by users), so we haven't tried
upstreaming it yet.  Still, it is useful and I'm interested in
collecting requirements for when we get back to polishing it.
