include/opcode/
* mips.h: Remove documentation of "[" and "]". Update documentation
of "k" and the MDMX formats.
opcodes/
* mips-opc.c (mips_builtin_opcodes): Use "Q" for the INSN_5400
MDMX-like instructions.
* mips-dis.c (print_insn_arg): Use "$f" rather than "$v" when
printing "Q" operands for INSN_5400 instructions.
gas/
* config/tc-mips.c (validate_mips_insn): Remove "[" and "]" handling.
(mips_ip): Likewise. Do not set is_mdmx for INSN_5400 instructions.
Check constraints on the VR5400 RZU.OB, SLL.OB and SRL.OB instructions.
gas/testsuite/
* gas/mips/vr5400-ill.s, gas/mips/vr5400-ill.l: New test.
* gas/mips/mips.exp: Run it.
