[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.
