bfd/
* archures.c: Add definition for bfd_mach_arm_iWMMXt2.
* cpu-arm.c (processors): Add bfd_mach_arm_iWMMXt2.
(arch_info_struct, bfd_arm_update_notes): Likewise.
(architectures): Likewise.
(bfd_arm_merge_machines): Check for iWMMXt2.
* bfd-in2.h: Rebuild.
gas/
* config/tc-arm.c (enum operand_parse_code): New code OP_RIWR_I32z.
(parse_operands): Handle OP_RIWR_I32z.
(do_iwmmxt_wmerge): New function.
(do_iwmmxt_wldstd): Handle iwmmxt2 case where second operand is
a register.
(do_iwmmxt_wrwrwr_or_imm5): New function.
(insns): Mark instructions as RIWR_I32z as appropriate.
Also add torvsc<b,h,w>, wabs<b,h,w>, wabsdiff<b,h,w>,
waddbhus<l,m>, waddhc, waddwc, waddsubhx, wavg4{r}, wmaddu{x,n},
wmadds{x,n}, wmerge, wmiaxy{n}, wmiawxy{n}, wmul<sm,um>{r},
wmulw<um,sm,l>{r}, wqmiaxy{n}, wqmulm{r}, wqmulwm{r}, wsubaddhx.

gas/testsuite/
* gas/arm/iwmmxt2.s: New file.
* gas/arm/iwmmxt2.d: New file.
opcodes/
* arm-dis.c (coprocessor_opcodes): The X-qualifier to WMADD may
only be used with the default multiply-add operation, so if N is
set, don't bother printing X. Add new iwmmxt instructions.
(IWMMXT_INSN_COUNT): Update.
(iwmmxt_wwssnames): Qualify "wwss" names at index 2, 6, 10 and 14
with a 'c' suffix.
(print_insn_coprocessor): Check for iWMMXt2. Handle format
specifiers 'r', 'i'.
