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.

65f2205d60 [AArch64][PATCH 10/14] Rework code mapping vector types to operand qualifiers.
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.

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.

73af8ed6b1 [AArch64][Patch 1/5] Support the ARMv8.2 Statistical Profiling Extension.
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.

af117b3cf1 [AArch64] Fix ARMv8.1 and ARMv8.2 feature settings.
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.

c740885937 arc/gas: Accept, but ignore, dummy arguments.
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.

ec892a0718 sparc: support %dN and %qN syntax for FP registers.
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.

35c1a43964 gas: don't get confused by .asci{i,z} after .struct
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.

870181955b [AArch64] Add feature flags and command line for ARMv8.2 FP16 support.
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.

9c352f1c23 [AArch64] Add support for Cortex-A35
This patch adds support to the AArch64 back-end for the Cortex-A35
processor, as recently announced by ARM. The ARM Cortex-A35 provides
full support for the ARMv8-A architecture, including the CRC extension,
with optional Advanced-SIMD and Floating-Point support. We therefore set
feature flags for this CPU to AARCH64_ARCH_V8 and AARCH64_FEATURE_CRC, in
the same fashion as Cortex-A53 and Cortex-A57.

Tested in a cross environment for AArch64 with no issues.

This patch adds support for the R_X86_64_GOTPCRELX and
R_X86_64_REX_GOTPCRELX relocations proposed in

https://groups.google.com/forum/#!topic/x86-64-abi/n9AWHogmVY0

to gas and ld.  It updates gas to generate R_X86_64_GOTPCRELX,
R_X86_64_REX_GOTPCRELX if there is a REX prefix, relocation for memory
operand, foo@GOTPCREL(%rip).  With the locally defined symbol, foo, we
convert

  mov foo@GOTPCREL(%rip), %reg

to

   lea foo(%rip), %reg

and convert

   call/jmp *foo@GOTPCREL(%rip)
to

   nop call foo/jmp foo nop

When PIC is false, convert

   test %reg, foo@GOTPCREL(%rip)
to

test $foo, %reg

and convert

   binop foo@GOTPCREL(%rip), %reg

to

   binop $foo, %reg

where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

02a866936d Add R_386_GOT32X support to gas and ld
This patch adds support for the R_386_GOT32X relocation proposed in

https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I

to gas and ld.  It updates gas to generate R_386_GOT32X relocation for
memory operand, foo@GOT[(%reg)].  We must encode "mov foo@GOT, %eax"
with the 0x8b opcode, instead of the 0xb8 opcode, so that it can be
transformed to "lea foo, %eax".  With the locally defined symbol, foo,
we convert

   mov foo@GOT[(%reg1)], %reg2
to
   lea foo[@GOTOFF(%reg1)], %reg2

and convert

   call/jmp *foo@GOT[(%reg)]
to

   nop call foo/jmp foo nop

When PIC is false, convert

   test %reg1, foo@GOT[(%reg2)]
to
   test $foo, %reg1

and convert

binop foo@GOT[(%reg1)], %reg2

to

binop $foo, %reg2

where binop is one of adc, add, and, cmp, or, sbb, sub, xor instructions.

edeefb6792 Add --enable-compressed-debug-sections={all,gas,gold,ld}
This patch removes the gas configure option:

--enable-compressed-debug-sections

and adds a toplevel configure option:

--enable-compressed-debug-sections={all,gas,gold,ld}

to enable compressed debug sections for gas, gold or ld by default.  At
the moment, this configure option is ignored by gold and ld.  For x86
Linux targets, default to compressing debug sections in gas.
