The FP16 feature is optional in ARMv8.2, so it is wrong to add it to
the default AARCH64_ARCH_V8_2 feature flags. This patch makes the
behaviour consistent with that of gcc, which also does not assume FP16
for ARMv8.2.

This matches the ISA specification. This also adds two tests: one to

we only relax valid 'c.lui's.

FT32B is a new FT32 family member. It has a code
compression scheme, which requires the use of linker
relaxations. The change is quite large, so submission
is in several parts.
Part 1 adds a 15-bit instruction field, and CPU-specific functions for
the code compression that are used in binutils and GDB.

Correct a commit 7d64c587c1 ("Add support for the MIPS eXtended
Physical Address (XPA) ASE.") bug, causing XPA base and Virtualization
ASE instructions to be wrongly always enabled with the selection of the
MIPS32r2 or higher ISA.
For example this source assembles successfully as shown below:
$ cat xpa.s
mfhc0 $2, $1
$ as -32 -mips32 -o xpa.o xpa.s
xpa.s: Assembler messages:
xpa.s:1: Error: opcode not supported on this processor: mips32 (mips32) `mfhc0 $2,$1'
$ as -32 -mips32r2 -o xpa.o xpa.s
$ objdump -d xpa.o
xpa.o: file format elf32-tradbigmips
Disassembly of section .text:
00000000 <.text>:
0: 40420800 mfhc0 v0,c0_random
...
$
To address this issue remove the I33 (INSN_ISA32R2) marking from all XPA
instructions in the opcode table. Additionally, for XPA Virtualization
ASE instructions implement an XPAVZ (ASE_XPA_VIRT) combination ASE flag
and use it in place of IVIRT|XPA (ASE_VIRT|ASE_XPA).
Now the same source is correctly rejected unless the `-mxpa' option is
also used:
$ as -32 -mips32r2 -o xpa.o xpa.s
xpa.s: Assembler messages:
xpa.s:1: Error: opcode not supported on this processor: mips32r2 (mips32r2) `mfhc0 $2,$1'
$ as -32 -mips32r2 -mxpa -o xpa.o xpa.s
$
Add test cases for XPA base and XPA Virtualization ASE instructions.

=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to add support for ARMv8-R in GAS:
instructions, build attributes and readelf.
=== Patch description ===
Although some differences exist for system registers, from GAS point of
view ARMv8-R supports the same instructions as ARMv8-A Aarch32 state
and a subset of its extensions. This patch therefore introduce a new
feature bit to distinguish the availability of the pan, ras and rdma
extensions between ARMv8-A and ARMv8-R and allow crypto, fp and simd
extensions to be used by ARMv8-R.
Most of the changes are then in the testsuite to (i) rename source files
and error output to be shared between ARMv8-A and ARMv8-R, (ii) rename
files with expected output for ARMv8-A build attributes and (iii) add
new files with expected output for ARMv8-R build attributes.

=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to remove special casing for ARMv6S-M
autodetection.
=== Motivation ===
Currently, SWI and SVC mnemonics are enabled for ARMv4T and successor
architectures with extra checks in the handler function (do_t_swi) to
give an error message when ARMv6-M is targeted and some more special
casing in aeabi_set_public_attributes. This was made to exclude these
mnemonics for ARMv6-M unless the OS extension is in use.
However this logic is superfluous: there is already code to check
whether an instruction is available based on the feature bit it is part
of and whether the targeted architecture has that feature bit. This
patch aims at removing that unneeded complexity.
=== Patch description ===
The OS extension is already limited to the ARMv6-M architecture so all
this patch does is redefined availability of the ARM_EXT_OS feature bit
to not be present for ARM_ARCH_V6M. ARM_ARCH_V6SM does not need any
change either because it already includes ARM_EXT_OS.
The patch also make sure that the error message that was given by
do_t_swi when SWI/SVC is unavailable is still the same by detecting the
situation in md_assemble.

=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to rework the Tag_CPU_arch build attribute
value selection to (i) match architecture or CPU if specified by user
without any need for hack and (ii) match an architecture with all the
features used if in autodetection mode or return an error.
=== Motivation ===
Currently, Tag_CPU_arch build attribute value selection assumes that an
architecture is always a superset of architectures released earlier. As
such, the logic is to browse architectures in chronological order of
release and selecting the Tag_CPU_arch value of the last one to
contribute a feature used[1]/requested[2] not contributed by earlier
architectures.
[1] in case of autodetection mode
[2] otherwise, ie. in case of -mcpu/-march or associated directives
This logic fails the two objectives mentionned in the Context section.
First, due to the assumption it does an architecture can be selected
while not having all the features used/requested which fails the second
objective. Second, not doing an exact match when an architecture or CPU
is selected by the user means the wrong value is chosen when a later
architecture provides a subset of the feature bits of an earlier
architecture. This is the case for the implementation of ARMv8-R (see
later patch).
An added benefit of this patch is that it is possible to easily generate
more consistent build attribute by setting the feature bits from the
architecture matched in aeabi_set_public_attributes in autodetection
mode. This is better done as a separate patch because lots of testcase'
expected results must then be updated accordingly.
=== Patch description ===
The patch changes the main logic for Tag_CPU_arch and
Tag_CPU_arch_profile
values selection to:
- look for an exact match in case an architecture or CPU was specified
on the command line or in a directive
- select the first released architecture that provides a superset of the
feature used in the autodetection case
- select the most featureful architecture in case of -march=all
The array cpu_arch_ver is updated to include all architectures in order
to make the first point work.
Note that when looking for an exact match, the architecture with
selected extension is tried first and then only the architecture. This
is because some architectures are exactly equivalent to an earlier
architecture with its extensions selected. ARMv6S-M (= ARMv6-M + OS
extension) and ARMv6KZ (ARMv6K + security extension) are two such
examples.
Other adjustments are also necessary in aeabi_set_public_attributes to
make this change work.
1) The logic to set Tag_ARM_ISA_use and Tag_THUMB_ISA_use must check the
absence of feature bit used/requested to decide whether to give the
default value for empty files (see EABI attribute defaults test). It was
previously checking that arch == 0 which would only happen if no feature
bit could be matched by any architecture, ie there is no feature bit to
match.
2) A fallback to a superset match must exist when no_cpu_selected ()
returns true. This is because aeabi_set_public_attributes is called
again after relaxation and at this point selected_cpu is set from the
previous execution of that function. There is therefore no way to check
whether the user specified an architecture or CPU.
3) Tag_CPU_arch lines are removed from expected output when the
detected architecture should be pre-ARMv4, since 0 is the Tag_CPU_arch
value for pre-ARMv4 architectures and default value for an absent entry
is 0.

So far we only had an instruction flag which made an arbitrary number
of operands optional. This limits error checking capabilities for
instructions marked that way. With this patch the optparm flag only
allows a single optional parameter and another one is added (optparm2)
allowing 2 optional arguments. Hopefully we won't need more than that
in the future. So far there will be only a single use of optparm2.

* opcode/arc.h (MAX_INSN_FLGS): Update to 4.
Add MIPS16e2 ASE support as per the architecture specification[1],
including in particular:
1. A new ELF ASE flag to mark MIPS16e2 binaries.
2. MIPS16e2 instruction assembly support, including a relaxation update
to use LUI rather than an LI/SLL instruction pair for loading the
high part of 32-bit addresses.
3. MIPS16e2 instruction disassembly support, including updated rules for
extended forms of instructions that are now subdecoded and therefore
do not alias to the original MIPS16 ISA revision instructions even
for encodings that are not valid in the MIPS16e2 instruction set.
Add `-mmips16e2' and `-mno-mips16e2' GAS command-line options and their
corresponding `mips16e2' and `no-mips16e2' settings for the `.set' and
`.module' pseudo-ops. Control the availability of the MT ASE subset of
the MIPS16e2 instruction set with a combination of these controls and
the preexisting MT ASE controls.

PPC_OPCODE_* renumbered to fill the gaps left by previous patches,

This bit is also useless as it can be replaced with PPC_OPCODE_POWER9.
Defining the VSX2 and VSX3 selection based on cpu bits also lets the
assembler/disassembler distinguish between the power7 VSX opcodes and
the power8 ones. Note that this change means -mvsx now reverts back

This bit is worse than useless. Using it prevents the assembler and

This adds support of new instructions to the S/390 specific parts.
The important feature of the new instruction set is the support of
single and extended precision floating point vector operations.
Note: arch12 is NOT the official name of the new CPU. It just
continues the series of archXX options supported as alternate names.
The archXX terminology refers to the edition number of the Principle
of Operations manual. The official CPU name will be added later while
keeping support of the arch12 for backwards compatibility.
No testsuite regressions.
Committed to mainline.

Identify non-extensible instructions in the MIPS16 opcode table and
disallow their use with the `.e' instruction size suffix in assembly and
do not interpret any EXTEND prefix present as a part of the instruction
in disassembly.
According to all versions of the MIPS16 ASE specifications the following
instructions encodings are not extensible [1][2][3][4][5][6]: I8/MOV32R,
I8/MOVR32, all RRR minor opcodes, all RR minor opcodes except from DSRA
and DSRL, and EXTEND itself, and as from revision 2.50 of the MIPS16e
ASE specifications it has been further clarified what was previously
implied, that non-extesiable instructions when preceded with an EXTEND
prefix must cause a Reserved Instruction exception [3][5].
Therefore in the presence of an EXTEND prefix none of these instructions
are supposed to be handled as extended instructions and supporting these
forms in disassembly causes confusion, and in the case of the RRR major
opcode it also clashes with the ASMACRO encoding.

Switch to 32-bit MIPS16 opcode table entry interpretation, similar to
how the microMIPS opcode table is handled, for both the `match' and
`mask' fields, removing special casing for JAL and JALX instructions and
their `a' and `i' operand codes throughout, while retaining automatic
processing of extendable opcodes in assembly and disassembly.
In assembly disallow size enforcement suffixes as appropriate: `.t' for
both 32-bit instructions and macros and `.e' for macros only, making
macro handling consistent with the microMIPS instruction set.
In disassembly fully decode EXTEND prefixes prepended to unsupported
instruction encodings (according to the ISA selection) rather than
dumping them as hexadecimal data along with the following instruction,
removing all special casing for the EXTEND prefix and making its
handling rely on its opcode table entry, except where it is considered a

When the assembler finds an instruction which is part of a higher
opcode architecture it bumps the current opcode architecture. For
example:
$ echo "mwait" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait"
However, when two instructions pertaining to the same opcode
architecture but associated to different SPARC hardware capabilities
are found in the input stream, and no GAS architecture is specified in
the command line, the assembler bangs:
$ echo "mwait; wr %g0,%g1,%mcdper" | as -bump
{standard input}: Assembler messages:
{standard input}:1: Warning: architecture bumped from "v6" to "v9m" on "mwait"
{standard input}:1: Error: Hardware capability "sparc5" not enabled for "wr".
... and it should'nt, as WRMCDPER pertains to the same architecture
level than MWAIT.
This patch fixes this by extending the definition of sparc opcode
architectures to contain a set of hardware capabilities and making the
assembler to take these capabilities into account when updating the
set of allowed hwcaps when an architecture bump is triggered by some
instruction.
This way, hwcaps associated to architecture levels are maintained in
opcodes, while the assembler keeps the flexibiity of defining GAS
architectures including additional hwcaps (like -Asparcfmaf or the
v8plus* variants).
A test covering this failure case is included.

The current handling for arc instructions longer than 32-bits is all
handled as a special case in both the assembler and disassembler.
The problem with this approach is that it leads to code duplication,
selecting a long instruction is exactly the same process as selecting a
short instruction, except over more bits, in both cases we select based
on bit comparison, and initial operand insertion and extraction.
This commit unifies both the long and short instruction worlds,
converting the core opcodes library from being largely 32-bit focused,
to being largely 64-bit focused.
The changes are, on the whole, not too much. There's obviously a lot of
type changes but otherwise the bulk of the code just works. Most of the
actual functional changes are to code that previously handled the longer
48 or 64 bit instructions. The insert/extract handlers for these have
now been brought into line with the short instruction insert/extract
handlers.
All of the special case handling code that was previously added has now
been removed again. Overall, this commit reduces the amount of code in
the arc assembler and disassembler.

The ARC (short) instructions are using a special register number to
indicate is the instruction uses a long immediate (LIMM). In the case
of short instruction, this LIMM indicator depends on the ISA version
used. Thus, for ARCv1 processors, the LIMM indicator is 0x3E, the same
value used in "long" instructions. However, for the ARCv2 processors,
this LIMM indicator is 0x1E.
This patch fixes the LIMM detection for ARCv1 ISA and adds two tests.

SVE defines new names for existing NZCV conditions, to reflect the
result of instructions like PTEST. This patch adds support for these
names.
The patch also adds comments to the disassembly output to show the
alternative names of a condition code. For example:
cinv x0, x1, cc
becomes:
cinv x0, x1, cc // cc = lo, ul, last
and:
b.cc f0 <...>
becomes:
b.cc f0 <...> // b.lo, b.ul, b.last
Doing this for the SVE names follows the practice recommended by the
SVE specification and is definitely useful when reading SVE code.
If the feeling is that it's too distracting elsewhere, we could add
an option to turn it off.

The main purpose of the SVE aarch64_insn_classes is to describe how
an index into an aarch64_opnd_qualifier_seq_t is represented in the
instruction encoding. Other instructions usually use flags for this
information, but (a) we're running out of those and (b) the iclass
would otherwise be unused for SVE.

This patch adds support for the new SVE floating-point immediate
operands. One operand uses the same 8-bit encoding as base AArch64,
but in a different position. The others use a single bit to select
between two values.
One of the single-bit operands is a choice between 0 and 1, where 0
is not a valid 8-bit encoding. I think the cleanest way of handling
these single-bit immediates is therefore to use the IEEE float encoding
itself as the immediate value and select between the two possible values
when encoding and decoding.
As described in the covering note for the patch that added F_STRICT,
we get better error messages by accepting unsuffixed vector registers
and leaving the qualifier matching code to report an error. This means
that we carry on parsing the other operands, and so can try to parse FP
immediates for invalid instructions like:
fcpy z0, #2.5
In this case there is no suffix to tell us whether the immediate should
be treated as single or double precision. Again, we get better error
messages by picking one (arbitrary) immediate size and reporting an error
for the missing suffix later.

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).

This patch adds support for addresses of the form:

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.

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).

The SVE instructions have two enumerated operands: one to select a
vector pattern and another to select a prefetch operation. The latter
is a cut-down version of the base AArch64 prefetch operation.
Both types of operand can also be specified as raw enum values such as #31.
Reserved values can only be specified this way.
If it hadn't been for the pattern operand, I would have been tempted
to use the existing parsing for prefetch operations and add extra
checks for SVE. However, since the patterns needed new enum parsing
code anyway, it seeemed cleaner to reuse it for the prefetches too.
Because of the small number of enum values, I don't think we'd gain
anything by using hash tables.

SVE has some instructions in which the same register appears twice
in the assembly string, once as an input and once as an output.
This patch adds a general mechanism for that.
The patch needs to add new information to the instruction entries.
One option would have been to extend the flags field of the opcode
to 64 bits (since we already rely on 64-bit integers being available
on the host). However, the *_INSN macros mean that it's easy to add
new information as top-level fields without affecting the existing
table entries too much. Going for that option seemed to give slightly
neater code.

SVE predicate operands can appear in three forms:
1. unsuffixed: "Pn"
2. with a predication type: "Pn/[ZM]"
3. with a size suffix: "Pn.[BHSD]"
No variation is allowed: unsuffixed operands cannot have a (redundant)
suffix, and the suffixes can never be dropped. Unsuffixed Pn are used
in LDR and STR, but they are also used for Pg operands in cases where
the result is scalar and where there is therefore no choice to be made
between "merging" and "zeroing". This means that some Pg operands have
suffixes and others don't.
It would be possible to use context-sensitive parsing to handle
this difference. The tc-aarch64.c code would then raise an error
if the wrong kind of suffix is used for a particular instruction.
However, we get much more user-friendly error messages if we parse
all three forms for all SVE instructions and record the suffix as a
qualifier. The normal qualifier matching code can then report cases
where the wrong kind of suffix is used. This is a slight extension
of existing usage, which really only checks for the wrong choice of
suffix within a particular kind of suffix.
The only catch is a that a "NIL" entry in the qualifier list
specifically means "no suffix should be present" (case 1 above).
NIL isn't a wildcard here. It also means that an instruction that
requires all-NIL qualifiers can fail to match (because a suffix was
supplied when it shouldn't have been); this requires a slight change
to find_best_match.
This patch adds an F_STRICT flag to select this behaviour.
The flag will be set for all SVE instructions. The behaviour
for other instructions doesn't change.

Feature flag handling was not perfect, +nofp16 disabled fp
instructions too.
New feature flag macros were added to check features with multiple
bits set (matters for FP_F16 and SIMD_F16 opcode feature tests).
The unused AARCH64_OPCODE_HAS_FEATURE was removed, all checks should
use one of the AARCH64_CPU_HAS_* macros. AARCH64_CPU_HAS_FEATURE
now checks all feature bits.
The aarch64_features table now contains the dependencies as
a separate field (so when the feature is enabled all dependencies
are enabled and when it is disabled everything that depends on it
is disabled).
Note that armv8-a+foo+nofoo is not equivalent to armv8-a if
+foo turns on dependent features that nofoo does not turn off.

aarch64_opnd_info used bitfields to hold vector element indices,
but values were stored into those bitfields before their ranges had
been checked. This meant large invalid indices could be silently
truncated to smaller valid indices.
The two obvious fixes were to do the range checking earlier or use
a full 64-bit field for the index. I went for the latter for two
reasons:
- Doing the range checking in operand_general_constraint_met_p
seems structurally cleaner than doing it while parsing.
- The bitfields didn't really buy us anything. The imm field
of the union is already 128 bits, so we can use a full int64_t
index without growing the structure.
The patch also adds missing range checks for the elements in a register
list index.

The code supporting -mspfp, -mdpfp, and -mfpuda options are in
sections of code that are commented as being for backward
compatibility only, and having no effect. However, they do have an
effect, enabling the SPX, DPX, and DPA instruction subclasses
respectively. This commit moves the code supporting these options
away from the comments indicating that they are dummy options, and
also fixes a small issue where -mnps400 had the additional effect
of enabling SPX instructions.
A couple of other minor edits (that make no functional change) are
also included.

bfd_mach_sparc_v9{c,d,e,v,m} and bfd_mach_sparc_v8plus{c,d,e,v,m}.
Note that for arches up to v9b (UltraSPARC III), the detection of the
BFD machine type was based on the bits in the e_machine field of the ELF
header. However, there are no more available bits in that field, so
this patch takes the approach of using the hardware capabilities stored
in the object attributes HWCAPS/HWCAPS2 in order to characterize the
machine the object was built for.

When parsing the operand instruction flags we don't currently detect the
case where multiple flags are provided from the same class set, these
will be accepted and the bit values merged together, resulting in the
wrong instruction being assembled. For example:
adc.n.eq r0,r0,r2
Will assemble without error, yet, upon disassembly, the instruction will
actually be:
adc.c r0,r0,r2
In a later commit the concept of required flags will be introduced.
Required flags are just like normal instruction flags, except that they
must be present for the instruction to match. Adding this will allow
for simpler instructions in the instruction table, and allow for more
sharing of operand extraction and insertion functions.
To solve both of the above issues (multiple flags being invalid, and
required flags), this commit reworks the flag class mechanism.
Currently the flag class is never used. Each instruction can reference
multiple flag classes, each flag class has a class type and a set of
flags. However, at present, the class type is never used. The current
values identify the type of instruction that the flag will be used in,
but this is not required information.
Instead, this commit discards the old flag classes, and introduces 3 new
classes. The first F_CLASS_NONE, is just a NULL marker value, and is
only used in the NULL marker flag class. The other two flag classes are
F_FLAG_OPTIONAL, and F_FLAG_REQUIRED.
The class F_FLAG_OPTIONAL has the property that at most one of the flags
in the flag set for that class must be present in the instruction. The
"at most" one means that no flags being present is fine.
The class F_FLAG_REQUIRED is not currently used, but will be soon. With
this class, exactly one of the flags from this class must be present in
the instruction. If the flag class contains a single flag, then of
course that flag must be present. However, if the flag class contained
two or more, then one, and only one of them must be present.

This commit introduces the nps400 machine type as a variant of arc.
There's a new flag in the assembler to select this machine type. All
other changes are just adding handling of the new machine type into the
relevant places.
The nps400 is an arc700 variant with some vendor specific instructions
added into the instruction set. This commit does not add any of the new
instructions, this is just laying the groundwork for future commits.
However, in preparation for these new instructions a new opcode define for
nps400 has been added to include/opcode/arc.h, this new opcode define is
used in the assembler and disassembler along with the existing define
for arc700 such that when assembling and disassembling for nps400 the
user will have access to all arc700 instructions and all the nps400
vendor extension instructions.

This commit restructures the selection of the default cpu/mach so that
the choice is made from md_begin (if the user has not provided a command
line choice). This will reduce the amount of change needed in a later
patch.
At the request of Synopsys, the default architecture changes to ARC700
from this commit, previously the default was a non-existent
super-architecture that contained all instructions from all arc
variants. There's some clean up associated with removing the default
merged architecture, and a small test fix now that the default is
ARC700.

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.

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 series adds
support for this instruction to binutils, enabled when -march=armv8.2-a
is selected.
The AArch64 binutils record of some system registers uses a boolean
value to hold the single flag currently supported for them. To allow
these registers to be limited to specific architectures, the first patch
in this series replaces the boolean flag with a bitset and feature test.

The ARMv8.2 RAS extension adds a new barrier instruction ESB as an alias
and the preferred form of HINT 16.
This patch adds an architectural feature flag for the RAS extension and
includes it in the features selected enabled by -march=armv8.2-a. It
also adds the ESB instruction, making it available whenever the RAS
feature is enabled.
Because ESB is the preferred form and because the target architecture
isn't available to the disassembler, HINT 16 will be disassembled as ESB
even when the target has no support for the RAS extension.

ARMv8.2 adds two new instructions: BFC as an alias for BFM and REV64 as
an alias for REV. This patch set adds support for these to binutils,
enabled when the -march=armv8.2-a is given. It depends on the support
for an instruction being its preferred form which was added in an
earlier patch.
This patch adds the alias BFC <Rd>, #<imm>, #<width> as the preferred
form for BFM when the source is a zero register and the conditions for
using the BFI form are met (in other words, BFC is the preferred form
for BFI <Rd>, <Rs>, #<imm>, #<width> when the <Rs> is a zero register).

ARMv8.2 adds optional support for 16-bit operations to the FP and
Adv.SIMD instructions. This patch adds a feature macro for this support
with a new command line option "+fp16" to enable/disable it.
Although the command line option is added as an architecture extension,
it only affects instructions available with when +fp or +simd is
enabled. If +fp16 is specified then it will also enable +fp.
There are currently no FP16 instructions implemented in binutils, this
patch is to enable subsequent work on supporting the extension.

Nowadays aarch64_decode_insn is a public interface used by both
opcodes and gdb. However, its behaviour relies on a global variable
no_aliases, which isn't a good practise. On the other hand, In default,
no_aliases is zero, but in GDB, we do want no alias when decoding
instructions for prologue analysis (patches to be posted), so that we
can handle both instructions "add" and "mov" (an alias of "add") as
"add". The code in GDB can be simplified.
This patch adds a new argument in aarch64_decode_insn, and pass no_aliases
to it. In GDB side, always pass 1 to it.

* opcode/ft32.h: Add instruction macros FT32_*()
Back in the day support for these processors was added, we probably
didn't want to waste PPC_OPCODE bits on minor variations. I've had a
complaint that disassembly of mfspr/mtspr was wrong for power8. This
patch fixes that problem.
Note that since -m860/-m850/-m821 are new gas options enabling the
mpc8xx specific mfspr/mtspr variants it is possible that this change
will break some mpc8xx assembly code. ie. you might need to modify
makefiles to pass -m860 to gas.

ISA 2.07 (ie, POWER8) added the rfebb instruction which takes one operand
with the value of either a 0 or 1. It also defines an extended mnemonic
with no operands (ie, "rfebb") that is supposed to be equivalent to "rfebb 1".
I implemented rfebb's lone operand with PPC_OPERAND_OPTIONAL, but the
problem is, optional operands that are ommitted always default to the
value 0, which is wrong in this case. I have added support for allowing
non-zero default values by adding an additional flag PPC_OPERAND_OPTIONAL_VALUE
that specifies that the default operand value to be used is stored in the
SHIFT field of the operand field immediately following this one.
This fixes the rfebb issue. I also fixed the mftb and mfcr instructions
so they use the same mechanism. This allows us to flag invalid uses of
mfcr where we explicitly pass in a zero FXM value, like the use in a2.[sd].

First, add nds32 audio ISA extension including opcodes and registers.
Second, redesign the disassemble implement.
The original disassemble decode instruction opcode using switch-case.
It is hard to synchronize when adding new instructions.
Therefore, the new implement reuses nds32_opcodes to dump the instructions.

If a 16-bit offset is not suitable for the instruction we're

ADDRESS_ADDI_INSN. Make the M_LI_DD code fall through into the
M_L_DAB code once the address has been constructed. For double load

If the second register cannot be accessed from the same high
part as the first, load it into AT using ADDRESS_ADDI_INSN.
Fix the handling of LD in cases where the first register is the
same as the base. Also handle the case where the offset is
not 16 bits and the second register cannot be accessed from the
same high part as the first. For unaligned loads and stores,
fuse the offbits == 12 and old "ab" handling. Apply this handling
