- Subject: [Patch, AArch64] Support optional LSL #0 in 8-bit form MOVI as an architecture syntax instead of a programmer-friendly feature
Hi,
This patch changes the AArch64 GAS and opcode to support the optional
LSL #0 in 8-bit form MOVI instructions as an architecture syntax instead
of a programmer-friendly feature. This is to conform to the change in
the latest ARMv8 ISA.
The patch has no effect on the tools' behaviour from the user's
perspective, except for some diagnostics improvement in GAS in a couple
of cases.
OK to commit?
Thanks,
Yufeng

* aarch64.h (aarch64_op): Remove OP_V_MOVI_B.
opcodes/
2013-01-14 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.
gas/
2013-01-14 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.
