Subject:         * ada-lang.c (static_unwrap_type): Add forward declaration.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f192137b09a5f99ef0ab14f19cb7160871f25963;p=binutils-gdb.git

    * ada-lang.c (static_unwrap_type): Add forward declaration.
        (template_to_static_fixed_type): Fields of dynamic types sometimes
        also need to be unwrapped. Take this into account.
        (ada_to_fixed_type_1): Renamed from ada_to_fixed_type.
        (ada_to_fixed_type): New wrapper around ada_to_fixed_type_1.
        * ada-typeprint.c (ada_print_type): Get the typename from
        the original type, not the base type.
