* aarch64.h (aarch64_op): Remove OP_V_MOVI_B.
opcodes/
2013-01-17 Yufeng Zhang <yufeng.zhang@arm.com>
* aarch64-asm.c (aarch64_ins_advsimd_imm_modified): Handle 8-bit MOVI.
* aarch64-dis.c (aarch64_ext_advsimd_imm_modified): Likewise.
* aarch64-opc.c (operand_general_constraint_met_p): For
AARCH64_MOD_LSL, move the range check on the shift amount before the
alignment check; change to call set_sft_amount_out_of_range_error
instead of set_imm_out_of_range_error.
* aarch64-tbl.h (QL_SIMD_IMM_B): Replace NIL with LSL.
(aarch64_opcode_table): Remove the OP enumerator from the asimdimm
8-bit MOVI entry; change the 2nd operand from SIMD_IMM to
SIMD_IMM_SFT.

2013-01-17 Yufeng Zhang <yufeng.zhang@arm.com>
* config/tc-aarch64.c (output_operand_error_record): Change to output
the out-of-range error message as value-expected message if there is
only one single value in the expected range.
(programmer_friendly_fixup): Remove the handling of 8-bit MOVI with
LSL #0 as a programmer-friendly feature.
gas/testsuite/
2013-01-17 Yufeng Zhang <yufeng.zhang@arm.com>
* gas/aarch64/diagnostic.l: Update.
* gas/aarch64/movi.s: Add tests.
* gas/aarch64/movi.d: Update.
* gas/aarch64/programmer-friendly.s: Add comment.
