opcodes/
2013-08-06 Jürgen Urban <JuergenUrban@gmx.de>
* mips-opc.c (mips_builtin_opcodes): Add a suffixless version of
VCLIPW.
gas/
2013-08-06 Jürgen Urban <JuergenUrban@gmx.de>
* config/tc-mips.c (match_vu0_suffix_operand): Allow single-channel
suffixes to be elided too.
(mips_lookup_insn): Don't reject INSN2_VU0_CHANNEL_SUFFIX here.
(mips_ip): Assume .xyzw if no VU0 suffix is specified. Allow +N
to be omitted too.
gas/testsuite/

* gas/mips/r5900-error-vu0.s, gas/mips/r5900-error-vu0.l,
gas/mips/r5900-full-vu0.s, gas/mips/r5900-full-vu0.d: Allow
single-channel suffixes to be elided.
