[BINUTILS, AArch64, 2/2] Update Store Allocation Tag instructions
This patch updates the Store allocation tags instructions in
Armv8.5-A Memory Tagging Extension. This is part of the changes
that have been introduced recently in the 00bet10 release
All of these instructions have an updated register operand (Xt -> <Xt|SP>)
- STG <Xt|SP>, [<Xn|SP>, #<simm>]
- STG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STG <Xt|SP>, [<Xn|SP>], #<simm>
- STZG <Xt|SP>, [<Xn|SP>, #<simm>]
- STZG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZG <Xt|SP>, [<Xn|SP>], #<simm>
- ST2G <Xt|SP>, [<Xn|SP>, #<simm>]
- ST2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- ST2G <Xt|SP>, [<Xn|SP>], #<simm>
- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]
- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZ2G <Xt|SP>, [<Xn|SP>], #<simm>
In order to accept <Rt|SP> a new operand type Rt_SP is introduced which has
the same field as FLD_Rt but follows other semantics of Rn_SP.

Fix AArch64 encodings for by element instructions.
Some instructions in Armv8-a place a limitation on FP16 registers that can be
used as the register from which to select an element from.
e.g. fmla restricts Rm to 4 bits when using an FP16 register. This restriction
does not apply for all instructions, e.g. fcmla does not have this restriction
as it gets an extra bit from the M field.
Unfortunately, this restriction to S_H was added for all _Em operands before,
meaning for a large number of instructions you couldn't use the full register
file.
This fixes the issue by introducing a new operand _Em16 which applies this
restriction only when paired with S_H and leaves the _Em and the other
qualifiers for _Em16 unbounded (i.e. using the full 5 bit range).
Also the patch updates all instructions that should be affected by this.

[AArch64][SVE 27/32] Add SVE integer immediate operands
This patch adds the new SVE integer immediate operands. There are
three kinds:
- simple signed and unsigned ranges, but with new widths and positions.
- 13-bit logical immediates. These have the same form as in base AArch64,
but at a different bit position.
In the case of the "MOV Zn.<T>, #<limm>" alias of DUPM, the logical
immediate <limm> is not allowed to be a valid DUP immediate, since DUP
is preferred over DUPM for constants that both instructions can handle.
- a new 9-bit arithmetic immediate, of the form "<imm8>{, LSL #8}".
In some contexts the operand is signed and in others it's unsigned.
As an extension, we allow shifted immediates to be written as a single
integer, e.g. "#256" is equivalent to "#1, LSL #8". We also use the
shiftless form as the preferred disassembly, except for the special
case of "#0, LSL #8" (a redundant encoding of 0).

Modify the ARNM assembler to accept the omission of the immediate argument for the writeback form of the LDRAA and LDRAB mnemonics
This is a shorthand for the immediate argument being 0, as described here:
https://developer.arm.com/docs/ddi0596/latest/base-instructions-alphabetic-order/ldraa-ldrab-load-register-with-pointer-authentication
This is because the instructions still have a use with an immediate
argument of 0, unlike loads without the PAC functionality. Currently,
the mnemonics are
LDRAA Xt, [Xn, #<simm10>]!
LDRAB Xt, [Xn, #<simm10>]!
After this patch they become
LDRAA Xt, [Xn {, #<simm10>}]!

[PATCH, BINUTILS, AARCH64, 7/9] Add BTI instruction
This patch is part of the patch series to add support for ARMv8.5-A
extensions.
(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/ddi0596/a/a64-base-instructions-alphabetic-order/bti-branch-target-identification)
The Branch Target Identification instructions (BTI) are allocated to
existing HINT space, using HINT numbers 32, 34, 36, 38, such that
bits[7:6] of the instruction identify the compatibility of the BTI
instruction to different branches.
BTI {<targets>}
where <targets> one of the following, specifying which type of
indirection is allowed:
j : Can be a target of any BR Xn isntruction.
c : Can be a target of any BLR Xn and BR {X16|X17}.
jc: Can be a target of any free branch.
A BTI instruction without any <targets> is the strictest of all and
can not be a target of nay free branch.

[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.

[AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands. A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.
The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

[AArch64][SVE 27/32] Add SVE integer immediate operands
This patch adds the new SVE integer immediate operands. There are
three kinds:
- simple signed and unsigned ranges, but with new widths and positions.
- 13-bit logical immediates. These have the same form as in base AArch64,
but at a different bit position.
In the case of the "MOV Zn.<T>, #<limm>" alias of DUPM, the logical
immediate <limm> is not allowed to be a valid DUP immediate, since DUP
is preferred over DUPM for constants that both instructions can handle.
- a new 9-bit arithmetic immediate, of the form "<imm8>{, LSL #8}".
In some contexts the operand is signed and in others it's unsigned.
As an extension, we allow shifted immediates to be written as a single
integer, e.g. "#256" is equivalent to "#1, LSL #8". We also use the
shiftless form as the preferred disassembly, except for the special
case of "#0, LSL #8" (a redundant encoding of 0).

[AArch64][SVE 24/32] Add AARCH64_OPND_SVE_PATTERN_SCALED
Some SVE instructions count the number of elements in a given vector
pattern and allow a scale factor of [1, 16] to be applied to the result.
This scale factor is written ", MUL #n", where "MUL" is a new operator.
E.g.:
UQINCD X0, POW2, MUL #2
This patch adds support for this kind of operand.
All existing operators were shifts of some kind, so there was a natural
range of [0, 63] regardless of context. This was then narrowered further
by later checks (e.g. to [0, 31] when used for 32-bit values).
In contrast, MUL doesn't really have a natural context-independent range.
Rather than pick one arbitrarily, it seemed better to make the "shift"
amount a full 64-bit value and leave the range test to the usual
operand-checking code. I've rearranged the fields of aarch64_opnd_info
so that this doesn't increase the size of the structure (although I don't
think its size is critical anyway).

[AArch64][SVE 27/32] Add SVE integer immediate operands
This patch adds the new SVE integer immediate operands. There are
three kinds:
- simple signed and unsigned ranges, but with new widths and positions.
- 13-bit logical immediates. These have the same form as in base AArch64,
but at a different bit position.
In the case of the "MOV Zn.<T>, #<limm>" alias of DUPM, the logical
immediate <limm> is not allowed to be a valid DUP immediate, since DUP
is preferred over DUPM for constants that both instructions can handle.
- a new 9-bit arithmetic immediate, of the form "<imm8>{, LSL #8}".
In some contexts the operand is signed and in others it's unsigned.
As an extension, we allow shifted immediates to be written as a single
integer, e.g. "#256" is equivalent to "#1, LSL #8". We also use the
shiftless form as the preferred disassembly, except for the special
case of "#0, LSL #8" (a redundant encoding of 0).

[PATCH, BINUTILS, AARCH64, 2/9] Add Data procoessing instructions for ARMv8.5-A
This patch is part of the patch series to add support for ARMv8.5-A
extensions.
(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/ddi0596/a/a64-base-instructions-alphabetic-order)
This patch adds the data processing instructions that are new to
ARMv8.5-A.
1) There are 2 instructions: xaflag, axflag, that are added to
manipulate the states of the flag and are used to convert between the
Arm representation and the fcmp representation.
2) The other instructions are rounding instructions which have 8
versions based on whether the floating-point number is a
Single-Precision or Double-Precision number, whether the target
integer is a 32-bit or 64-bit integer and whether the rounding mode is
the ambient rounding mode or to zero. Each of these instruction is
available in both Scalar and Vector forms.
Since both 1) and 2) have separate identification mechanism and it is
permissible that a ARMv8.4 compliant implementation may include any
arbitrary subset of the ARMv8.5 features unless otherwise specified,
new feature bits are added.

(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/ddi0596/a/a64-base-instructions-alphabetic-order)
This patch adds the data processing instructions that are new to
ARMv8.5-A.
1) There are 2 instructions: xaflag, axflag, that are added to
manipulate the states of the flag and are used to convert between the
Arm representation and the fcmp representation.
2) The other instructions are rounding instructions which have 8
versions based on whether the floating-point number is a
Single-Precision or Double-Precision number, whether the target
integer is a 32-bit or 64-bit integer and whether the rounding mode is
the ambient rounding mode or to zero. Each of these instruction is
available in both Scalar and Vector forms.
Since both 1) and 2) have separate identification mechanism and it is
permissible that a ARMv8.4 compliant implementation may include any
arbitrary subset of the ARMv8.5 features unless otherwise specified,
new feature bits are added.

[PATCH, BINUTILS, AARCH64, 2/9] Add Data procoessing instructions for ARMv8.5-A
This patch is part of the patch series to add support for ARMv8.5-A
extensions.
(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/ddi0596/a/a64-base-instructions-alphabetic-order)
This patch adds the data processing instructions that are new to
ARMv8.5-A.
1) There are 2 instructions: xaflag, axflag, that are added to
manipulate the states of the flag and are used to convert between the
Arm representation and the fcmp representation.
2) The other instructions are rounding instructions which have 8
versions based on whether the floating-point number is a
Single-Precision or Double-Precision number, whether the target
integer is a 32-bit or 64-bit integer and whether the rounding mode is
the ambient rounding mode or to zero. Each of these instruction is
available in both Scalar and Vector forms.
Since both 1) and 2) have separate identification mechanism and it is
permissible that a ARMv8.4 compliant implementation may include any
arbitrary subset of the ARMv8.5 features unless otherwise specified,
new feature bits are added.
