Matthew Wahab 4fd0a9fd00 [AArch64][PATCH 14/14] Support FP16 Adv.SIMD Scalar Shift By Immediate instructions.
ARMv8.2 adds 16-bit floating point operations as an optional extension
to the floating point and Adv.SIMD support. This patch extends
instructions in the group Adv.SIMD Scalar Shift By Immediate to support
FP16, making this support available when +simd+fp16 is enabled.

The extended instructions are: SCVTF, FCVTZS, UCVTF and FCVTZU.

The general form for these instructions is
   <OP> <Hd>, <Hs>, #<imm>

Matthew Wahab b5b0f34c66 [AArch64][PATCH 13/14] Support FP16 Adv.SIMD Shift By Immediate instructions.
ARMv8.2 adds 16-bit floating point operations as an optional extension
to the floating point and Adv.SIMD support. This patch extends
instructions in the group Adv.SIMD Shift By Immediate to support FP16,
making this support available when +simd+fp16 is enabled.

The new instructions legal make some uses of the 4h vector type that had
been invalid. This patch adjusts a test that checks for these uses.

The extended instructions are: SCVTF, FCVTZS, UCVTF and FCVTZU.

The general form for these instructions is
   <OP> <Vd>.<T>, <Vs>.<T>, #<imm>
   where T is 4h or 8h.

Matthew Wahab 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.

Matthew Wahab 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.

Matthew Wahab 64357d2e04 [AArch64] Add ARMv8.2 instruction alias REV64.
This patch adds the alias REV64 <Rd>, <Rs> as an alias for REV <Rd>,
<Rs>. However, REV is still the preferred form for the instruction.

Matthew Wahab d685192a58 [AArch64] Add ARMv8.2 instructions BFC and REV64.
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).

Matthew Wahab 35822b3812 [AArch64] Let aliased instructions be their preferred form.
Although the AArch64 backend supports aliased instructions, the aliasing
forms are always preferred over the real instruction. This makes it
awkward to handle instructions which have aliases but which are their
own preferred form.

This patch includes the instruction being aliased in the list of
alternatives which is searched when considering which form to use.
