ff6054520c [PATCH, BINUTILS, AARCH64, 7/9] Add BTI instruction 
This patch is part of the patch series to add support for ARMv8.5-A
extensions.
(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/ddi0596/a/a64-base-instructions-alphabetic-order/bti-branch-target-identification)

The Branch Target Identification instructions (BTI) are allocated to
existing HINT space, using HINT numbers 32, 34, 36, 38, such that
bits[7:6] of the instruction identify the compatibility of the BTI
instruction to different branches.

	BTI {<targets>}

where <targets> one of the following, specifying which type of
indirection is allowed:

	j : Can be a target of any BR Xn isntruction.
	c : Can be a target of any BLR Xn and BR {X16|X17}.
	jc: Can be a target of any free branch.

A BTI instruction without any <targets> is the strictest of all and
can not be a target of nay free branch.

13c60ad7e1 [PATCH, BINUTILS, AARCH64, 2/9] Add Data procoessing instructions for ARMv8.5-A 
This patch is part of the patch series to add support for ARMv8.5-A
extensions.
(https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/ddi0596/a/a64-base-instructions-alphabetic-order)

This patch adds the data processing instructions that are new to
ARMv8.5-A.

1) There are 2 instructions: xaflag, axflag, that are added to
manipulate the states of the flag and are used to convert between the
Arm representation and the fcmp representation.

2) The other instructions are rounding instructions which have 8
versions based on whether the floating-point number is a
Single-Precision or Double-Precision number, whether the target
integer is a 32-bit or 64-bit integer and whether the rounding mode is
the ambient rounding mode or to zero. Each of these instruction is
available in both Scalar and Vector forms.

Since both 1) and 2) have separate identification mechanism and it is
permissible that a ARMv8.4 compliant implementation may include any
arbitrary subset of the ARMv8.5 features unless otherwise specified,
new feature bits are added.

a68f4cd235 AArch64: Add SVE constraints verifier. 
This patch adds the verification rules for move prefix constraints.

The Arm SVE instruction MOVPRFX introduces[1] constraints on the instruction at
PC+4. Particularly the following constraints are handled by this patch

* MOVPRFX must be followed by an instruction.
* MOVPRFX can only be followed by non-layout altering directives.
* MOVPRFX destination register MUST be used as the destination register in the
  instruction at PC+4, and is not allowed to be used in any other position other than
  destructive input.  This includes registers that architecturally overlap. e.g. x1
  should be treated as z1.
* MOVPRFX must be followed by a restricted set of SVE instructions.
* The size of the destination register of MOVPRFX must be equal to that of
  the operation at PC+4.
* The predicate register and operation of MOVPRFX must match that of the instruction
  at PC+4
* The predicated instruction at PC+4 must use the merging predicate.
* Architectural aliases and pseudo-instructions need to be supported as well.
* MOVPRFX cannot be the last instruction in a sequence

Any failure to adhere to any of these constrains will emit an assembly warning
and a disassembly note.

755b748fd9 AArch64: Refactor verifiers to make more general. 
The current verifiers only take an instruction description and encoded value as
arguments.  This was enough when the verifiers only needed to do simple checking
but it's insufficient for the purposes of validating instruction sequences.

This patch adds the required arguments and also a flag to allow a verifier to
distinguish between whether it's being run during encoding or decoding.  It also
allows for errors and warnings to be returned by a verifier instead of a simple
pass/fail.

eae424aef0 AArch64: Mark sve instructions that require MOVPRFX constraints 
This patch series is to allow certain instructions such as the SVE MOVPRFX
instruction to apply a constraint/dependency on the instruction at PC+4.

This patch starts this off by marking which instructions impose the constraint
and which instructions must adhere to the constraint.  This is done in a
generic way by extending the verifiers.

* The constraint F_SCAN indicates that an instruction opens a sequence and imposes
a constraint on an instructions following it.  The length of the sequence depends
on the instruction itself and it handled in the verifier code.

* The C_SCAN_MOVPRFX flag is used to indicate which constrain the instruction is
checked against.  An instruction with both F_SCAN and C_SCAN_MOVPRFX starts a
block for the C_SCAN_MOVPRFX instruction, and one with only C_SCAN_MOVPRFX must
adhere to a previous block constraint is applicable.

The SVE instructions in this list have been marked according to the SVE
specification[1].

RISC-V: Add fence.tso instruction 
The RISC-V memory model has been ratified, and it includes an additional
fence: "fence.tso".  This pseudo instruction extends one of the
previously reserved full fence patterns to be less restrictive, and
therefor will execute correctly on all existing microarchitectures.
Thus there is no reason to allow this instruction to be disabled (or
unconverted to a full fence), so it's just unconditionally allowed.

I've added a test case for GAS to check that "fence.tso" correctly
assembles on rv32i-based targets.  I checked to see that "fence.tso"
appears in "gas.log", but that's the only testing I've done.

9cf7e5687f Use operand->extract to provide defaults for optional PowerPC operands 
Most optional operands to powerpc instructions use a default value of
zero, but there are a few exceptions.  Those have been handled by
PPC_OPERAND_OPTIONAL_VALUE and an entry in the powerpc_operands table
for the default value, smuggled in the shift field.  This patch
changes that to using the operand extract function to provide non-zero
defaults.

I've also moved the code determining whether optional operands are
provided or omitted, to the point the first optional operand is seen,
and allowed for the possibility of optional base register operands
in a future patch.

The patch does change the error you get on invalid assembly like

  ld 3,4

You'll now see "missing operand" rather than
"syntax error; end of line, expected `('".

b8891f8d62 Add support for the C_SKY series of processors. 
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants.  V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc.  There is support for bare-metal ELF targets and Linux with both glibc and uClibc.

This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics.  C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers.  (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about.

fa758a7046 PowerPC Improve support for Gekko & Broadway 
This is a relatively straightforward patch to improve support for the
IBM Gekko and IBM Broadway processors.  Broadway is functionally
equivalent to the IBM 750CL, while Gekko's functionality is a subset
of theirs.  The patch simplifies this reality and adds -mgekko and
-mbroadway as aliases for -m750cl.  I didn't feel it was worth wasting
a PPC_OPCODE_* bit to differentiate Gekko.  The patch adds a number of
simplified mnemonics for special purpose register access.  Notably,
Broadway adds 4 additional IBAT and DBAT registers but these are not
assigned sequential SPR numbers.

369c9167d4 Fix AArch64 encodings for by element instructions. 
Some instructions in Armv8-a place a limitation on FP16 registers that can be
used as the register from which to select an element from.

e.g. fmla restricts Rm to 4 bits when using an FP16 register.  This restriction
does not apply for all instructions, e.g. fcmla does not have this restriction
as it gets an extra bit from the M field.

Unfortunately, this restriction to S_H was added for all _Em operands before,
meaning for a large number of instructions you couldn't use the full register
file.

This fixes the issue by introducing a new operand _Em16 which applies this
restriction only when paired with S_H and leaves the _Em and the other
qualifiers for _Em16 unbounded (i.e. using the full 5 bit range).

Also the patch updates all instructions that should be affected by this.

f9830ec165 Implement Read/Write constraints on system registers on AArch64 
This patch adds constraints for read and write only system registers with the
msr and mrs instructions.  The code will treat having both flags set and none
set as the same.  These flags add constraints that must be matched up. e.g. a
system register with a READ only flag set, can only be used with mrs.  If The
constraint fails a warning is emitted.

Examples of the warnings generated:

test.s: Assembler messages:
test.s:5: Warning: specified register cannot be written to at operand 1 -- `msr dbgdtrrx_el0,x3'
test.s:7: Warning: specified register cannot be read from at operand 2 -- `mrs x3,dbgdtrtx_el0'
test.s:8: Warning: specified register cannot be written to at operand 1 -- `msr midr_el1,x3'

and disassembly notes:

0000000000000000 <main>:
   0:	d5130503 	msr	dbgdtrtx_el0, x3
   4:	d5130503 	msr	dbgdtrtx_el0, x3
   8:	d5330503 	mrs	x3, dbgdtrrx_el0
   c:	d5330503 	mrs	x3, dbgdtrrx_el0
  10:	d5180003 	msr	midr_el1, x3	; note: writing to a read-only register.

Note that because dbgdtrrx_el0 and dbgdtrtx_el0 have the same encoding, during
disassembly the constraints are use to disambiguate between the two.  An exact
constraint match is always prefered over partial ones if available.

As always the warnings can be suppressed with -w and also be made errors using
warnings as errors.

7d02540ab7 Allow non-fatal errors to be emitted and for disassembly notes be placed on AArch64 
This patch adds a new platform option "notes" that can be used to indicate if
disassembly notes should be placed in the disassembly as comments.

These notes can contain information about a failing constraint such as reading
from a write-only register.  The disassembly will not be blocked because of this
but -M notes will emit a comment saying that the operation is not allowed.

For assembly this patch adds a new non-fatal status for errors.  This is
essentially a warning.  The reason for not creating an actual warning type is
that this causes the interaction between the ordering of warnings and errors to
be problematic.  Currently the error buffer is almost always filled because of
the way operands are matched during assembly. An earlier template may have put
an error there that would only be displayed if no other template matches or
generates a higher priority error.  But by definition a warning is lower
priority than a warning, so the error (which is incorrect if another template
matched) will supersede the warning.  By treating warnings as errors and only
later relaxing the severity this relationship keeps working and the existing
reporting infrastructure can be re-used.

561a72d4dd Modify AArch64 Assembly and disassembly functions to be able to fail and report why. 
This patch if the first patch in a series to add the ability to add constraints
to system registers that an instruction must adhere to in order for the register
to be usable with that instruction.

These constraints can also be used to disambiguate between registers with the
same encoding during disassembly.

This patch adds a new flags entry in the sysreg structures and ensures it is
filled in and read out during assembly/disassembly. It also adds the ability for
the assemble and disassemble functions to be able to gracefully fail and re-use
the existing error reporting infrastructure.

The return type of these functions are changed to a boolean to denote success or
failure and the error structure is passed around to them. This requires
aarch64-gen changes so a lot of the changes here are just mechanical.

Old (<= 2.8.1) versions of gcc generate broken fsubp, fsubrp, fdivp and

5b616beff4 [ARM] Remove ARM_FEATURE_COPY macro 
Among the macros to manipulate an arm_feature_set structure is the
ARM_FEATURE_COPY which copy the value of a feature set into another.
This can be achieved with a simple assignement which most of the

remove the macro altogether.

00c2093f69 Correct disassembly of dot product instructions. 
Dot products deviate from the normal disassembly rules for lane indexed
instruction. Their canonical representation is in the form of:

v0.2s, v0.8b, v0.4b[0] instead of v0.2s, v0.8b, v0.b[0] to try to denote
that these instructions select 4x 1 byte elements instead of a single 1 byte
element.

Previously we were disassembling them following the normal rules, this patch
corrects the disassembly.

a3b3345ae6 Add support for V_4B so we can properly reject it. 
Previously parse_vector_type_for_operand was changed to allow the use of 4b
register size for indexed lane instructions. However this had the unintended
side effect of also allowing 4b for normal vector registers.

Because this support was only partial the rest of the tool silently treated
4b as 8b and continued. This patch adds full support for 4b so it can be
properly distinguished from 8b and the correct errors are generated.

With this patch you still can't encode any instruction which actually requires
v<num>.4b but such instructions don't exist so to prevent needing a workaround
in get_vreg_qualifier_from_value this was just omitted.

	+aes: Enables the AES instructions of Armv8-a,
	      enabled by default with +crypto.

	+sha2: Enables the SHA1 and SHA2 instructions of Armv8-a,
	       enabled by default with +crypto.

These options have been turned on by default when +crypto
is used, as such no breakage is expected.

The reason for the split is because with the introduction of Armv8.4-a
the implementation of AES has explicitly been made independent of the
implementation of the other crypto extensions. Backporting the split does
not break any of the previous requirements and so is safe to do.

1270b047fd RISC-V: Add satp as an alias for sptbr 
The RISC-V privileged ISA changed the name of sptbr (Supervisor Page

paging.  This patch adds an alias, as they're the same register.

c05e0c5af3 aarch64: Remove AARCH64_FEATURE_F16 from AARCH64_ARCH_V8_2 
The FP16 feature is optional in ARMv8.2, so it is wrong to add it to

behaviour consistent with that of gcc, which also does not assume FP16
for ARMv8.2.

3b4b0a629a FT32: support for FT32B processor - part 1 
FT32B is a new FT32 family member. It has a code
compression scheme, which requires the use of linker
relaxations. The change is quite large, so submission
is in several parts.

Part 1 adds a 15-bit instruction field, and CPU-specific functions for
the code compression that are used in binutils and GDB.

To address this issue remove the I33 (INSN_ISA32R2) marking from all XPA
instructions in the opcode table.  Additionally, for XPA Virtualization
ASE instructions implement an XPAVZ (ASE_XPA_VIRT) combination ASE flag
and use it in place of IVIRT|XPA (ASE_VIRT|ASE_XPA).

Now the same source is correctly rejected unless the `-mxpa' option is
also used:

$ as -32 -mips32r2 -o xpa.o xpa.s
xpa.s: Assembler messages:
xpa.s:1: Error: opcode not supported on this processor: mips32r2 (mips32r2) `mfhc0 $2,$1'
$ as -32 -mips32r2 -mxpa -o xpa.o xpa.s
$

Add test cases for XPA base and XPA Virtualization ASE instructions.

ced40572e4 [ARM] Add support for ARMv8-R in assembler and readelf 
=== Context ===

This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to add support for ARMv8-R in GAS:
instructions, build attributes and readelf.

=== Patch description ===

Although some differences exist for system registers, from GAS point of
view ARMv8-R supports the same instructions as ARMv8-A Aarch32 state
and a subset of its extensions. This patch therefore introduce a new
feature bit to distinguish the availability of the pan, ras and rdma
extensions between ARMv8-A and ARMv8-R and allow crypto, fp and simd
extensions to be used by ARMv8-R.

Most of the changes are then in the testsuite to (i) rename source files
and error output to be shared between ARMv8-A and ARMv8-R, (ii) rename
files with expected output for ARMv8-A build attributes and (iii) add
new files with expected output for ARMv8-R build attributes.

173205ca33 [ARM] Remove ARMv6S-M special casing 
=== Context ===

This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to remove special casing for ARMv6S-M
autodetection.

=== Motivation ===

Currently, SWI and SVC mnemonics are enabled for ARMv4T and successor
architectures with extra checks in the handler function (do_t_swi) to
give an error message when ARMv6-M is targeted and some more special
casing in aeabi_set_public_attributes. This was made to exclude these
mnemonics for ARMv6-M unless the OS extension is in use.

However this logic is superfluous: there is already code to check
whether an instruction is available based on the feature bit it is part
of and whether the targeted architecture has that feature bit. This
patch aims at removing that unneeded complexity.

=== Patch description ===

The OS extension is already limited to the ARMv6-M architecture so all
this patch does is redefined availability of the ARM_EXT_OS feature bit
to not be present for ARM_ARCH_V6M. ARM_ARCH_V6SM does not need any
change either because it already includes ARM_EXT_OS.

The patch also make sure that the error message that was given by
do_t_swi when SWI/SVC is unavailable is still the same by detecting the
situation in md_assemble.

2c6b98ea6f [ARM] Rework Tag_CPU_arch build attribute value selection 
=== Context ===

This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to rework the Tag_CPU_arch build attribute
value selection to (i) match architecture or CPU if specified by user
without any need for hack and (ii) match an architecture with all the
features used if in autodetection mode or return an error.

=== Motivation ===

Currently, Tag_CPU_arch build attribute value selection assumes that an
architecture is always a superset of architectures released earlier. As
such, the logic is to browse architectures in chronological order of
release and selecting the Tag_CPU_arch value of the last one to
contribute a feature used[1]/requested[2] not contributed by earlier
architectures.

[1] in case of autodetection mode
[2] otherwise, ie. in case of -mcpu/-march or associated directives

This logic fails the two objectives mentionned in the Context section.
First, due to the assumption it does an architecture can be selected
while not having all the features used/requested which fails the second
objective. Second, not doing an exact match when an architecture or CPU
is selected by the user means the wrong value is chosen when a later
architecture provides a subset of the feature bits of an earlier
architecture. This is the case for the implementation of ARMv8-R (see
later patch).

An added benefit of this patch is that it is possible to easily generate
more consistent build attribute by setting the feature bits from the
architecture matched in aeabi_set_public_attributes in autodetection
mode. This is better done as a separate patch because lots of testcase'
expected results must then be updated accordingly.

=== Patch description ===

The patch changes the main logic for Tag_CPU_arch and
Tag_CPU_arch_profile
values selection to:
- look for an exact match in case an architecture or CPU was specified
  on the command line or in a directive
- select the first released architecture that provides a superset of the
  feature used in the autodetection case
- select the most featureful architecture in case of -march=all
The array cpu_arch_ver is updated to include all architectures in order
to make the first point work.

Note that when looking for an exact match, the architecture with
selected extension is tried first and then only the architecture. This
is because some architectures are exactly equivalent to an earlier
architecture with its extensions selected. ARMv6S-M (= ARMv6-M + OS
extension) and ARMv6KZ (ARMv6K + security extension) are two such
examples.

Other adjustments are also necessary in aeabi_set_public_attributes to
make this change work.

1) The logic to set Tag_ARM_ISA_use and Tag_THUMB_ISA_use must check the
absence of feature bit used/requested to decide whether to give the
default value for empty files (see EABI attribute defaults test). It was
previously checking that arch == 0 which would only happen if no feature
bit could be matched by any architecture, ie there is no feature bit to
match.

2) A fallback to a superset match must exist when no_cpu_selected ()
returns true. This is because aeabi_set_public_attributes is called
again after relaxation and at this point selected_cpu is set from the
previous execution of that function. There is therefore no way to check
whether the user specified an architecture or CPU.

3) Tag_CPU_arch lines are removed from expected output when the
detected architecture should be pre-ARMv4, since 0 is the Tag_CPU_arch
value for pre-ARMv4 architectures and default value for an absent entry
is 0.

a09f258601 S/390: Improve error checking for optional operands 
So far we only had an instruction flag which made an arbitrary number
of operands optional.  This limits error checking capabilities for
instructions marked that way.  With this patch the optparm flag only
allows a single optional parameter and another one is added (optparm2)
allowing 2 optional arguments.  Hopefully we won't need more than that
in the future. So far there will be only a single use of optparm2.

25499ac7ee MIPS16e2: Add MIPS16e2 ASE support 
Add MIPS16e2 ASE support as per the architecture specification[1],
including in particular:

1. A new ELF ASE flag to mark MIPS16e2 binaries.

2. MIPS16e2 instruction assembly support, including a relaxation update
   to use LUI rather than an LI/SLL instruction pair for loading the
   high part of 32-bit addresses.

3. MIPS16e2 instruction disassembly support, including updated rules for
   extended forms of instructions that are now subdecoded and therefore
   do not alias to the original MIPS16 ISA revision instructions even
   for encodings that are not valid in the MIPS16e2 instruction set.

Add `-mmips16e2' and `-mno-mips16e2' GAS command-line options and their
corresponding `mips16e2' and `no-mips16e2' settings for the `.set' and
`.module' pseudo-ops.  Control the availability of the MT ASE subset of
the MIPS16e2 instruction set with a combination of these controls and
the preexisting MT ASE controls.

Parts of this change by Matthew Fortune and Andrew Bennett.

c03dc33b60 Reorder PPC_OPCODE_* and set PPC_OPCODE_TMR for e6500 
PPC_OPCODE_* renumbered to fill the gaps left by previous patches,
and reordered chronologically just because.  I kept PPC_OPCODE_TMR
because presumably it might be used in future APUinfo for e6500.

include/
	* opcode/ppc.h (PPC_OPCODE_*): Renumber and order chronologically.
	(PPC_OPCODE_SPE): Comment on this and other bits used for APUinfo.

9570835e55 Bye Bye PPC_OPCODE_VSX3 
This bit is also useless as it can be replaced with PPC_OPCODE_POWER9.
Defining the VSX2 and VSX3 selection based on cpu bits also lets the
assembler/disassembler distinguish between the power7 VSX opcodes and
the power8 ones.  Note that this change means -mvsx now reverts back
to just adding the power7 VSX insns.
