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.

This patch adds support for the opcode architectures
SPARC_OPCODE_ARCH_V9{C,D,E,V,M} and its associated BFD machine numbers
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.

add a new relocation type.
There's a test of the new instructions in the assembler, and a test of
the relocation in the linker.

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].
