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.

Correct a MIPS16 relocation handling regression in GAS introduced with:
commit 177b4a6ad0
Author: Alexandre Oliva <aoliva@redhat.com>
Date: Mon Mar 18 18:56:18 2002 +0000
discussed at <https://sourceware.org/ml/binutils/2002-03/msg00345.html>,
which removed a preparatory call to `mips16_extended_frag' previously
made from `md_estimate_size_before_relax'. As a result the function is
never called with its `sec' parameter non-NULL and consequently all the
unsupported relocation checks within are dead and never trigger, causing
any unhandled relocations to silently resolve to 0. Unfortunately there
was no sufficient test suite coverage back then to catch this.
Remove all dead code then, and all the associated comments. Update the
remaining call to `mips16_extended_frag' from `mips_relax_frag' to pass
the relocation section as the `sec' parameter and use it to mark frags
which require an external relocation, as extended. Finally handle any
outstanding MIPS16 relocations in `md_convert_frag' and report an error
since we don't support any except with percent operators.

The code supporting -mspfp, -mdpfp, and -mfpuda options are in

effect, enabling the SPX, DPX, and DPA instruction subclasses
respectively. This commit moves the code supporting these options

of enabling SPX instructions.

The PC-relative R_MIPS_PC18_S3 relocation and consequently its BFD
internal BFD_RELOC_MIPS_18_PCREL_S3 representation is calculated from
the address of the aligned doubleword containing the location being
relocated: (sign_extend(A) + S - (P & ~0x7)) >> 3 rather than the
address of the location itself. Reflect this in calculations made by
GAS so that the relocated field is set correctly if resolved by GAS,

relocations to be propagated to the link stage.

This is so that with e.g. code like this:
b foo
.set mips32r2
...
it's the command line options or any `.module' directive that decides
how to encode any relocation for `foo' rather than the presence of `.set
mips32r2'.

This patch marks the SPARC instructions in the opcodes table with their
proper opcode architectures, and makes the assembler aware of them.
This allows the assembler to properly realize when a new instruction
needs a higher architecture (after v9b) and to react accordingly
emitting an error message or bumping the architecture.
It also expands architecture mismatch tests to cover architectures
higher than v9b, and fixes a couple of minor bugs in the GAS testsuite.

The current sparc assembler breaks when the name of an ancillary-state
register, privileged register or hyperprivileged register has a
%-pseudo-operation name as a prefix. For example, %hmcdper and %hm(),
or %hintp and %hi().
This patch fixes it by introducing a new table `perc_table' (for
%-table) that contains an entry for every %name supported by the
assembler, other than the general registers. This table is used to
detect name collisions when the assembler tries to detect a %-pseudo-op.
This patch also fixes a related bug, making sure that v9a_asr_table and
hpriv_reg_table are sorted in reverse lexicographic order, as otherwise
the search code may fail.

instruction uses the same encoding as the ld instruction, but sets
the ZZ field to 11 (which is a reserved setting), and sets the AA
field to 1 or 2 for the x2 and x4 flags respectively.
With the exception of ldbit, this commit adds implementations of
all DPI instructions for the NPS-400. These instructions are:
- hash / hash.p[0-3]
- tr
- utf8
- e4by
- addf
Revert an inadvertent change to make RELA JALR relocations
section-relative on MIPS R6 targets made with commit 7361da2c95 ("Add
support for MIPS R6."). There is no need to make this a special case
and the comment introduced with the said change clearly indicates this
was not intended.

VLE is an encoding, not a particular processor architecture, so it
isn't really proper to select insns based on PPC_OPCODE_VLE. For
example
{"evaddw", VX (4, 512), VX_MASK, PPCSPE|PPCVLE, PPCNONE, {RS, RA, RB}},
{"vaddubs", VX (4, 512), VX_MASK, PPCVEC|PPCVLE, PPCNONE, {VD, VA, VB}},
shows two insns that have the same encoding, both available with VLE.
Enabling both with VLE means we can't disassemble the second variant
even if -Maltivec is given rather than -Mspe. Also, we don't check
user assembly against the processor type as well as we could.
Another problem is that when using the VLE encoding, insns from the
main ppc opcode table are not available, except those using opcode 4
and 31. Correcting this revealed two errors in the ld testsuite,
use of "nop" and "rfmci" when -mvle.
This patch fixes those problems in the opcode table, and removes
PPCNONE. I find a plain 0 distracts less from other values.
In addition, I've implemented code to recognize some machine values
from the apuinfo note present in ppc32 objects. It's not a complete
disambiguation since we're lacking info to detect newer chips, but
what we have should help with disassembly.

AMD64 spec and Intel64 spec differ in indirect branches in 64-bit mode.
AMD64 supports indirect branches with 16-bit address via the data size
prefix while the data size prefix is ignored by Intel64.
