[opcodes/ChangeLog]

2001-10-21  Chris Demetriou  <cgd@broadcom.com>

        * mips-opc.c (mips_builtin_opcodes): Mark "bgezall" and
        "bltzall" as writing GPR 31 (since they do).

        * mips-dis.c (print_insn_arg): Calculate info->target
        where appropriate.
        (print_insn_mips): Fill in instruction info.
        (print_mips16_insn_arg): Remove unneded variable 'val'.
        Removed duplicated instruction target calculations,
        calculate once and print that result.  Use same idiom for
        masking the jump segment bits as is used in print_insn_arg.

[gas/testsuite/ChangeLog]

2001-10-21  Chris Demetriou  <cgd@broadcom.com>

        * gas/mips/beq.s: Add zero words at end of instructions so
        that objdump will print "..." when disassembling.
        * gas/mips/beq.d: Update for disassembler changes which force
        branch delay-slot nops to be printed.
        * gas/mips/bge.d: Ditto.
        * gas/mips/bgeu.d: Ditto.
        * gas/mips/blt.d: Ditto.
        * gas/mips/bltu.d: Ditto.
        * gas/mips/jal-svr4pic.d: Ditto.
        * gas/mips/jal-xgot.d: Ditto.
