In the instruction to write to the ARMv8.2 PSTATE field UAO,
MSR UAO, #<imm>, the immediate should be either 0 or 1 but GAS accepts
any unsigned 4-bit integer.
This patch implements the constraint on the immediate, generating an
error if the immediate operand is invalid, and adds tests for the
illegal forms.

The POOL48A major opcode was defined in early revisions of the 64-bit

The convention within for relocation names is that they start with the
string "R_", however, this is not so for ARC for the display names of
relocations, however, internally, the names for the relocations types do
have the 'R_' prefix. I suspect that the missing 'R_' on the output
strings was an oversight, as I can't see any comment to the contrary.
To bring ARC into line with other targets, this commit adds the 'R_'
prefix to the output strings used for relocation names, and updates all
of the assembler tests where this was exposed.

ARMv8.2 adds 16-bit floating point operations as an optional extension
to the floating point and Adv.SIMD support. The FP16 additions to the
scalar pairwise group introduce a new vector type, 2H. This patch adds
support for this vector type to binutils.
The patch adds a new operand qualifier to the enum
aarch64.h:aarch64_opnd_qualifier. This interferes with the calculation
used by aarch64-dis.c:get_vreg_qualifier_from_value, called when
decoding an instruction. Since the new vector type is only used in FP16
scalar pairwise instructions which do not require the function, this
patch adjusts the function to ignore the new qualifier.

ARMv8.2 adds 16-bit floating point operations as an optional extension
to the floating point and Adv.SIMD support. The FP16 additions to the
scalar pairwise group introduce a new vector type. This patch reworks
code in the assembler to allow the addition of the new type.
The new vector type requires the addtion of a new operand qualifier to
the enum aarch64_opnd_qualifier which is defined
include/opcodes/aarch64.h, in the group prefixed by AARCH64_OPN_QLF_V_.
The correctness of the GAS utility function
tc-aarch64.c:vectype_to_qualifier is heavily dependent on the number and
ordering of this group. In particular, it makes assumptions about the
positions of the members of the group that are not true if a qualifier
for type 2H is added before the qualifier for 4H.
This patch reworks the function to weaken its assumptions, making it
calculate positions in the group from the type (B, H, S, D, Q) and
register width.

The Statistical Profile Extension adds the instruction PSB CSYNC as an

binutils as a HINT alias that takes an operand.
A new operand type, AARCH64_OPND_BARRIER_PSB, is added to represent the
operand to PSB. A parser for the operand type is added to the assembler
and a printer to the disassembler. The operand name "csync" is added to
the list of HINT options with HINT number #17. Encoding and decoding of
the operand is handled by the ins_hint/ext_hint functions added in the

The Statistical Profile extension included in the ARMv8.2 architecture
adds a number of system registers and a new instruction. This patch set
adds support for the extension to binutils, enabled when
-march=armv8.2-a+profile is given.
The patches in this series:
- Add the new command line option and feature flags.
- Add the new system registers.
- Adjust the maximum number of aliases permitted for an instruction.
- Add support for HINT aliases which take operands.
- Add the new instruction, an alias of the HINT instruction.
This patch adds the option "profile" to the permitted architecture
extensions, disabling it by default.

ARMv8.2 adds the new system instruction DC CVAP. This patch adds support
for the instruction to binutils, enabled when -march=armv8.2-a is
selected.

ARMv8.1 includes CRC as a required extension but this isn't reflected in
the features enabled by -march=armv8.1-a. The FP16 feature modifier also
clashes with AARCH64_FEATURE_V8_1 and the list of features for ARMv8.2
is missing ARMv8.1 features.
This patch enables +crc for -march values of armv8.1-a and later. It
also fixes the values for AARCH64_FEATURE_F16 and makes
AARCH64_ARCH_V8_2 and superset of AARCH64_ARCH_V8_2.
