Fred Fish d7deed257c * mips-dis.c (print_insn_arg): Add prototype. 
(_print_insn_mips): Ditto.

Ian Lance Taylor 44789bee66 whoops--typo 1996-09-02 16:41:29 +00:00
Ian Lance Taylor 01d34e4be3 file was really removed a long time ago 1996-09-02 16:41:28 +00:00
Jeff Law 09478dc331 * v850-dis.c (disassemble): Handle insertion of ',', '[' and 
']' characters into the output stream.
        * v850-opc.c (v850_opcodes: Remove size field from all opcodes.
        Add "memop" field to all opcodes (for the disassembler).
        Reorder opcodes so that "nop" comes before "mov" and "jr"
        comes before "jarl".
Should give us a functional disassembler.
