ARMv8.2 adds 16-bit floating point operations as an optional extension
to the floating point and Adv.SIMD support. This patch adds FP16
instructions to the group Adv.SIMD Scalar Pairwise, making them

The instructions added are: FMAXNMP, FADDP, FMAXP, FMINNMP and FMINP
The general form for these instructions is

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.

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. This patch reworks
code in the assembler to allow the addition of the new type.
The new vector type requires the addtion of a new operand qualifier to
the enum aarch64_opnd_qualifier which is defined
include/opcodes/aarch64.h, in the group prefixed by AARCH64_OPN_QLF_V_.
The correctness of the GAS utility function
tc-aarch64.c:vectype_to_qualifier is heavily dependent on the number and
ordering of this group. In particular, it makes assumptions about the
positions of the members of the group that are not true if a qualifier
for type 2H is added before the qualifier for 4H.
This patch reworks the function to weaken its assumptions, making it
calculate positions in the group from the type (B, H, S, D, Q) and
register width.

The ARMv8.2 RAS extension adds a new barrier instruction ESB as an alias

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.

ARMv8.1 includes CRC as a required extension but this isn't reflected in
the features enabled by -march=armv8.1-a. The FP16 feature modifier also
clashes with AARCH64_FEATURE_V8_1 and the list of features for ARMv8.2
is missing ARMv8.1 features.
This patch enables +crc for -march values of armv8.1-a and later. It
also fixes the values for AARCH64_FEATURE_F16 and makes
AARCH64_ARCH_V8_2 and superset of AARCH64_ARCH_V8_2.

There's a set of legacy command line arguments that the arc assembler
still accepts, however, these arguments not longer have any effect on
the assembler.
Currently we return false from md_parse_option for all of these
arguments, with the result that the assembler terminates with an error
message.
We should return true indicating that the argument has been accepted,
even though we ignore it.
gas/ChangeLog:
* config/tc-arc.c (md_parse_option): Return 1 in order to accept
dummy arguments.
The SPARC Refence Manual documents the %dN and %qN syntax to
refer to double and quad-precision floating-point registers,
respectively. See OSA2015 Appendix C, Assembly Language Syntax,
C1.1 Register Names.
This patch adds support for these names to GAS. This eases the
porting of software from Solaris to GNU/Linux, as these register
names have been supported by the Solaris linker for a long time
and many assembler require that support.

* config/tc-sparc.c (sparc_ip): Support %dN and %qN notation for
double and quad-precision floating-point registers.
While not allowed, this certainly shouldn't result in confusing the
programmer (by skipping lines in unexpected ways): Without returning,
demand_empty_rest_of_line() (at the end of the function) will demand
the _next_ line to be empty, and without the conditional we would
ignore the next line.
.file directives may be used to identify the scope of local symbols,
the purpose of which gets subverted when re-ordering them. Only allow
the first of them to be moved to the first position.
Various fixes to linker relaxation. In general, we need to support
relaxing every branch, even if we don't relax it in the assembler,

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.

Fix a test quality regression introduced with commit 351cdf24 [[MIPS]
Implement O32 FPXX, FP64 and FP64A ABI extensions] where MIPS ABI flags
match patterns have been added to negative-match tests covering ELF file
header flags. Negative-match tests succeed whenever there is a failure
in matching output produced and consequently the likelihood of a false
success increases when patterns to match irrelevant output are added.
Therefore remove the irrelevant paterns so that the tests complete as
soon as the line concerned has been seen.
