005d79fd61 PowerPC .gnu.attributes
This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs,
makes the assembler warn about undefined tag values, and removes
similar warnings from the linker.  I think it is better to not
warn in the linker about undefined tag values as future extensions to
the tags then won't result in likely bogus warnings.  This is
consistent with the fact that an older linker won't warn on an
entirely new tag.

I got an off-list request to make the AArch64 disassembler print

ab3b8fcfdb [AArch64] Use "must" rather than "should" in error messages
One of the review comments from the SVE series was that it would
be better to use "must" rather than "should" in error messages.
I think this patch fixes all cases in the AArch64 code.
It also uses "must be" instead of "expected to be".

bb7eff5206 [AArch64] Add SVE condition codes
SVE defines new names for existing NZCV conditions, to reflect the
result of instructions like PTEST.  This patch adds support for these
names.

The patch also adds comments to the disassembly output to show the
alternative names of a condition code.  For example:

	cinv	x0, x1, cc

becomes:

     	cinv	x0, x1, cc  // cc = lo, ul, last

and:

	b.cc	f0 <...>

becomes:

     	b.cc	f0 <...>  // b.lo, b.ul, b.last

Doing this for the SVE names follows the practice recommended by the
SVE specification and is definitely useful when reading SVE code.
If the feeling is that it's too distracting elsewhere, we could add
an option to turn it off.

165d495085 [AArch64][SVE 28/32] Add SVE FP immediate operands
This patch adds support for the new SVE floating-point immediate
operands.  One operand uses the same 8-bit encoding as base AArch64,
but in a different position.  The others use a single bit to select
between two values.

One of the single-bit operands is a choice between 0 and 1, where 0
is not a valid 8-bit encoding.  I think the cleanest way of handling
these single-bit immediates is therefore to use the IEEE float encoding
itself as the immediate value and select between the two possible values
when encoding and decoding.

As described in the covering note for the patch that added F_STRICT,
we get better error messages by accepting unsuffixed vector registers
and leaving the qualifier matching code to report an error.  This means
that we carry on parsing the other operands, and so can try to parse FP
immediates for invalid instructions like:

	fcpy	z0, #2.5

In this case there is no suffix to tell us whether the immediate should
be treated as single or double precision.  Again, we get better error
messages by picking one (arbitrary) immediate size and reporting an error
for the missing suffix later.

e950b34539 [AArch64][SVE 27/32] Add SVE integer immediate operands
This patch adds the new SVE integer immediate operands.  There are
three kinds:

- simple signed and unsigned ranges, but with new widths and positions.

- 13-bit logical immediates.  These have the same form as in base AArch64,
  but at a different bit position.

  In the case of the "MOV Zn.<T>, #<limm>" alias of DUPM, the logical
  immediate <limm> is not allowed to be a valid DUP immediate, since DUP
  is preferred over DUPM for constants that both instructions can handle.

- a new 9-bit arithmetic immediate, of the form "<imm8>{, LSL #8}".
  In some contexts the operand is signed and in others it's unsigned.
  As an extension, we allow shifted immediates to be written as a single
  integer, e.g. "#256" is equivalent to "#1, LSL #8".  We also use the
  shiftless form as the preferred disassembly, except for the special
  case of "#0, LSL #8" (a redundant encoding of 0).

98907a7049 [AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:

       [<base>, #<offset>, MUL VL]

This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.

For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, ....  The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.

4df068de52 [AArch64][SVE 25/32] Add support for SVE addressing modes
This patch adds most of the new SVE addressing modes and associated
operands.  A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.

The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.

2442d8466e [AArch64][SVE 24/32] Add AARCH64_OPND_SVE_PATTERN_SCALED
Some SVE instructions count the number of elements in a given vector
pattern and allow a scale factor of [1, 16] to be applied to the result.
This scale factor is written ", MUL #n", where "MUL" is a new operator.
E.g.:

	UQINCD	X0, POW2, MUL #2

This patch adds support for this kind of operand.

All existing operators were shifts of some kind, so there was a natural
range of [0, 63] regardless of context.  This was then narrowered further
by later checks (e.g. to [0, 31] when used for 32-bit values).

In contrast, MUL doesn't really have a natural context-independent range.
Rather than pick one arbitrarily, it seemed better to make the "shift"
amount a full 64-bit value and leave the range test to the usual
operand-checking code.  I've rearranged the fields of aarch64_opnd_info
so that this doesn't increase the size of the structure (although I don't
think its size is critical anyway).

245d2e3fe8 [AArch64][SVE 23/32] Add SVE pattern and prfop operands
The SVE instructions have two enumerated operands: one to select a
vector pattern and another to select a prefetch operation.  The latter
is a cut-down version of the base AArch64 prefetch operation.

Both types of operand can also be specified as raw enum values such as #31.
Reserved values can only be specified this way.

If it hadn't been for the pattern operand, I would have been tempted
to use the existing parsing for prefetch operations and add extra
checks for SVE.  However, since the patterns needed new enum parsing
code anyway, it seeemed cleaner to reuse it for the prefetches too.

Because of the small number of enum values, I don't think we'd gain
anything by using hash tables.

0c608d6b62 [AArch64][SVE 20/32] Add support for tied operands
SVE has some instructions in which the same register appears twice
in the assembly string, once as an input and once as an output.
This patch adds a general mechanism for that.

The patch needs to add new information to the instruction entries.
One option would have been to extend the flags field of the opcode
to 64 bits (since we already rely on 64-bit integers being available
on the host).  However, the *_INSN macros mean that it's easy to add
new information as top-level fields without affecting the existing
table entries too much.  Going for that option seemed to give slightly
neater code.

4989adac84 [AArch64][SVE 13/32] Add an F_STRICT flag
SVE predicate operands can appear in three forms:

1. unsuffixed: "Pn"
2. with a predication type: "Pn/[ZM]"
3. with a size suffix: "Pn.[BHSD]"

No variation is allowed: unsuffixed operands cannot have a (redundant)
suffix, and the suffixes can never be dropped.  Unsuffixed Pn are used
in LDR and STR, but they are also used for Pg operands in cases where
the result is scalar and where there is therefore no choice to be made
between "merging" and "zeroing".  This means that some Pg operands have
suffixes and others don't.

It would be possible to use context-sensitive parsing to handle
this difference.  The tc-aarch64.c code would then raise an error
if the wrong kind of suffix is used for a particular instruction.

However, we get much more user-friendly error messages if we parse
all three forms for all SVE instructions and record the suffix as a
qualifier.  The normal qualifier matching code can then report cases
where the wrong kind of suffix is used.  This is a slight extension
of existing usage, which really only checks for the wrong choice of
suffix within a particular kind of suffix.

The only catch is a that a "NIL" entry in the qualifier list
specifically means "no suffix should be present" (case 1 above).
NIL isn't a wildcard here.  It also means that an instruction that
requires all-NIL qualifiers can fail to match (because a suffix was
supplied when it shouldn't have been); this requires a slight change
to find_best_match.

This patch adds an F_STRICT flag to select this behaviour.
The flag will be set for all SVE instructions.  The behaviour
for other instructions doesn't change.

73866052f2 [AArch64][SVE 12/32] Remove boolean parameters from parse_address_main
In the review of the original version of this series, Richard didn't
like the use of boolean parameters to parse_address_main.  I think we
can just get rid of them and leave the callers to check the addressing
modes.  As it happens, the handling of ADDR_SIMM9{,_2} already did this
for relocation operators (i.e. it used parse_address_reloc and then
rejected relocations).

The callers are already set up to reject invalid register post-indexed
addressing, so we can simply remove the accept_reg_post_index parameter
without adding any more checks.  This again creates a corner case where:

	.equ	x2, 1
	ldr	w0, [x1], x2

was previously an acceptable way of writing "ldr w0, [x1], #1" but
is now rejected.

Removing the "reloc" parameter means that two cases need to check
explicitly for relocation operators.

ADDR_SIMM9_2 appers to be unused.  I'll send a separate patch
to remove it.

This patch makes parse_address temporarily equivalent to
parse_address_main, but later patches in the series will need
to keep the distinction.

	* config/tc-aarch64.c (parse_address_main): Remove reloc and

e1b988bba6 [AArch64][SVE 11/32] Tweak aarch64_reg_parse_32_64 interface
aarch64_reg_parse_32_64 is currently used to parse address registers,
among other things.  It returns two bits of information about the
register: whether it's W rather than X, and whether it's a zero register.

SVE adds addressing modes in which the base or offset can be a vector
register instead of a scalar, so a choice between W and X is no longer
enough.  It's more convenient to pass the type of register around as
a qualifier instead.

As it happens, two callers of aarch64_reg_parse_32_64 already wanted
the information in the form of a qualifier, so the change feels pretty
natural even without SVE.

Also, the function took two parameters to control whether {W}SP
and (W|X)ZR should be accepted.  We tend to get slightly better
error messages by accepting them regardless and getting the caller
to do the check, rather than potentially treating "xzr", "sp" etc.
as constants.  This is easier to do if the function returns the
reg_entry rather than just the register number.

This does create a corner case where:

	.equ	sp, 1
	ldr	w0, [x0, sp]

was previously an acceptable way of writing "ldr w0, [x0, #1]",
but I don't think it's important to continue supporting that.
We already rejected things like:

	.equ	sp, 1
	add	x0, x1, sp

To ensure these new error messages "win" when matching against
several candidate instruction entries, we need to use the same
address-parsing code for all addresses, including ADDR_SIMPLE
and SIMD_ADDR_SIMPLE.  The next patch also relies on this.

Finally, aarcch64_check_reg_type was written in a pretty
conservative way.  It should always be equivalent to a single
bit test.

6a9deabec4 [AArch64][SVE 09/32] Improve error messages for invalid floats
Previously:

would give an error:

whereas the user probably just forgot to add the ".0" to make:

        fmov d0, #2.0

This patch reports an invalid floating point constant unless the
operand is obviously a register.

The FPIMM8 handling is only relevant for SVE.  Without it:

        fmov z0, z1

would try to parse z1 as an integer immediate zero (the res2 path),
whereas it's more likely that the user forgot the predicate.  This is
tested by the final patch.

04a3379ace [AArch64][SVE 08/32] Generalise aarch64_double_precision_fmovable
SVE has single-bit floating-point constants that don't really
have any relation to the AArch64 8-bit floating-point encoding.
(E.g. one of the constants selects between 0 and 1.)  The easiest
way of representing them in the aarch64_opnd_info seemed to be
to use the IEEE float representation directly, rather than invent
some new scheme.

This patch paves the way for that by making the code that converts IEEE
doubles to IEEE floats accept any value in the range of an IEEE float,
not just zero and 8-bit floats.  It leaves the range checking to the
caller (which already handles it).

1799c0d064 [AArch64][SVE 07/32] Replace hard-coded uses of REG_TYPE_R_Z_BHSDQ_V
To remove parsing ambiguities and to avoid register names being
accidentally added to the symbol table, the immediate parsing
routines reject things like:

	.equ	x0, 0
	add	v0.4s, v0.4s, x0

An explicit '#' must be used instead:

	.equ	x0, 0
	add	v0.4s, v0.4s, #x0

Of course, it wasn't possible to predict what other register
names might be added in future, so this behaviour was restricted
to the register names that were defined at the time.  For backwards
compatibility, we should continue to allow things like:

	.equ	p0, 0
	add	v0.4s, v0.4s, p0

even though p0 is now an SVE register.

However, it seems reasonable to extend the x0 behaviour above to
SVE registers when parsing SVE instructions, especially since none
of the SVE immediate formats are relocatable.  Doing so removes the
same parsing ambiguity for SVE instructions as the x0 behaviour removes
for base AArch64 instructions.

As a prerequisite, we then need to be able to tell the parsing routines
which registers to reject.  This patch changes the interface to make
that possible, although the set of rejected registers doesn't change
at this stage.

a235d3aece [AArch64][SVE 01/32] Remove parse_neon_operand_type
A false return from parse_neon_operand_type had an overloaded
meaning: either the parsing failed, or there was nothing to parse
(which isn't necessarily an error).  The only caller, parse_typed_reg,
would therefore not consume the suffix if it was invalid but instead
(successfully) parse the register without a suffix.  It would still
leave inst.parsing_error with an error about the invalid suffix.

It seems wrong for a successful parse to leave an error message,
so this patch makes parse_typed_reg return PARSE_FAIL instead.

The patch doesn't seem to make much difference in practice.
Most possible follow-on errors use set_first_error and so the
error about the suffix tended to win despite the successful parse.

For each MAJOR-MINOR opcode tuple, we can have either a 3-operand, or

The disassembler is reading the section containing the extension
instruction format and stores them in a table.  Each table element
represents a linked list with encodings for a particular MAJOR-MINOR

5b64d091e9 X86: Allow additional ISAs for IAMCU in assembler
Originally only Pentium integer instructions are allowed for IAMCU.
This patch removes such a restriction.  For example, 387 and SSE2
instructions can be enabled by passing "-march=iamcu+sse2+387" to
assembler.

f7d69005fb PowerPC VLE sh_flags and p_flags
ELF section sh_flags SHF_PPC_VLE was being set based on arch/mach,
which meant all code sections in an object file has the flag or all
lacked it.  We can do better than that.  Only those code sections
where VLE is enabled ought to have the flag, allowing an object file
to contain both VLE and non-VLE code.

Also, ELF header p_flags PF_PPC_VLE wasn't being set, and segments
were being split unnecessarily.

bfd/
	* elf32-ppc.c (ppc_elf_section_processing): Delete.
	(elf_backend_section_processing): Don't define.
	(ppc_elf_modify_segment_map): Set p_flags and mark valid.  Don't
	split on non-exec sections differing in SHF_PPC_VLE.  When
	splitting segments, mark size invalid.
gas/
	* config/tc-ppc.c (md_assemble): Set sh_flags for VLE.  Test
	ppc_cpu rather than calling ppc_mach to determine VLE mode.
	(ppc_frag_check, ppc_handle_align): Likewise use ppc_cpu.
