gcc/:
        * godump.c (precision_to_units): New helper function.
        (go_append_artificial_name): Ditto.
        (go_append_decl_name): Ditto.
        (go_append_bitfield): Ditto.
        (go_get_uinttype_for_precision): Ditto.
        (go_append_padding): Ditto.
        (go_force_record_alignment): Ditto.
        (go_format_type): Represent unions with an array of uints of the size
        of the alignment in go.  This fixes the 'random' size of the union's
        representation using just the first field.
        (go_format_type): Add argument that indicates whether a record is
        nested (used for generation of artificial go names).
        (go_output_fndecl): Adapt to new go_format_type signature.
        (go_output_typedef): Ditto.
        (go_output_var): Ditto.
        (go_output_var): Prefer to output type as alias (typedef).
        (go_format_type): Bitfields in records are simulated as arrays of bytes
        in go.

        * godump.c (go_format_type): Fix handling of arrays with zero elements.
gcc/testsuite/:
        * gcc.misc-tests/godump.exp: New.
        * gcc.misc-tests/godump-1.c: New.
