Tamar Christina 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.

Tamar Christina 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.

Tamar Christina 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.

H.J. Lu bd5dea8822 x86: Remove support for old (<= 2.8.1) versions of gcc 
Old (<= 2.8.1) versions of gcc generate broken fsubp, fsubrp, fdivp and
fdivrp instructions.  Assembler translates them to correct ones with a
warning:

[hjl@gnu-cfl-1 gas]$ cat x.s

x.s: Assembler messages:
x.s:1: Warning: translating to `fsubp %st,%st(3)'
[hjl@gnu-cfl-1 gas]$

This patch removes support for old (<= 2.8.1) versions of gcc:

[hjl@gnu-cfl-1 gas]$ ./as-new -o x.o x.s

Thomas Preud'homme 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
existing code does. This patch removes the last 2 uses of that macro and
remove the macro altogether.

Tamar Christina 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.

Tamar Christina 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.

Nick Clifton c0e7cef715 Split the AArch64 Crypto instructions for AES and SHA1+2 into their own options (+aes and +sha2). 
The new options are:

	+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.

James Bowman 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.

Maciej W. Rozycki 9785fc2a4d MIPS: Fix XPA base and Virtualization ASE instruction handling 
Correct a commit 7d64c587c1 ("Add support for the MIPS eXtended
Physical Address (XPA) ASE.") bug, causing XPA base and Virtualization
ASE instructions to be wrongly always enabled with the selection of the
MIPS32r2 or higher ISA.

For example this source assembles successfully as shown below:

$ cat xpa.s
	mfhc0	$2, $1
$ as -32 -mips32 -o xpa.o xpa.s
xpa.s: Assembler messages:
xpa.s:1: Error: opcode not supported on this processor: mips32 (mips32) `mfhc0 $2,$1'
$ as -32 -mips32r2 -o xpa.o xpa.s
$ objdump -d xpa.o

xpa.o:     file format elf32-tradbigmips

Disassembly of section .text:

00000000 <.text>:
   0:	40420800 	mfhc0	v0,c0_random
	...
$

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.

Thomas Preud'homme 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.

Thomas Preud'homme 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.

Thomas Preud'homme 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.
