Subject:         * f-typeprint.c (f_type_print_base): Handle TYPE_CODE_REF.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7e86466e042a93e03168e155a3fda965c4b5cc0f;p=binutils-gdb.git

    * f-typeprint.c (f_type_print_base): Handle TYPE_CODE_REF.
        * f-valprint.c (f_val_print): Likewise.  Tweak TYPE_CODE_PTR to
        match c_val_print a bit closer.
