Dwarf2 with armcc compiler

[Tim Combs]

I've been trying to make gdb with with the armcc compiler. I've
already implemented DW_FORM_indirect and so far I've had decent 
success but I ran into a problem and wondered if I am on the right
track.
I get a core dump in decode_locdesc() in read_func_scope(). 
>From what I see in the Dwarf2 standard, a DW_TAG_frame_base expects 
either a DW_FORM_block? or a DW_FORM_?data?.  When I check the form 
of the attr, its a DW_FORM_addr.  If I change read_func_scope() to 
process the address correctly, I get a "Dwarf Error: Cannot find 
referent at offset X".  

Is it possible that a DW_TAG_frame_base can accept another form?

Thanks,
Tim
