4989adac84 [AArch64][SVE 13/32] Add an F_STRICT flag
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.

93d8990cba [AArch64] Fix +nofp16 handling
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.

dab26bf4e7 [AArch64] Make register indices be full 64-bit values
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.

3067d3b96c [AArch64][PATCH 11/14] Add support for the 2H vector type.
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.

1e6f4800fc [AArch64][Patch 5/5] Add instruction PSB CSYNC
The Statistical Profile Extension adds the instruction PSB CSYNC as an
alias for the HINT #17 instruction. This patch adds the instruction to
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
preceding patches.

c8a6db6fa0 [AArch64][PATCH 1/2] Add support for RAS instruction ESB.
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.

43cdf5aeb8 Pass noaliases_p to aarch64_decode_insn
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.

875880c661 Avoid using 'template' C++ keyword
'template' is used in include/opcode/aarch64.h as below,

 typedef struct
 {
   const char *template;
   uint32_t value;
   int has_xt;
 } aarch64_sys_ins_reg;

and it triggers compilation errors when GDB is built in C++ mode.

In file included from git/gdb/aarch64-tdep.c:62:0:
git/gdb/../include/opcode/aarch64.h:651:15: error: expected unqualified-id before 'template'
   const char *template;

This patch is to rename field template to name.
