One mod, rather than adding this:

> +# Evaluate DW_AT_calling_convention value and convert in a calling_convention
> +# value in the functions main type.
> +m::void:parse_dwarf2_calling_convention:int has_attr, unsigned long attr_val, unsigned char gcc_compiled, struct type *func_type:has_attr, attr_val, gcc_compiled, func_type:0:default_parse_dwarf2_calling_convention::0

to the architecture vector, take a look at:

13.2 Per-architecture module data
http://sources.redhat.com/gdb/current/onlinedocs/gdbint_13.html#SEC114

it lets dwarf2 locally manage that method while still being 
per-architecture.
