21df382b91 x86: fold SReg{2,3}
They're the only exception to there generally being no mix of register
kinds possible in an insn operand template, and there being two bits per
operand for their representation is also quite wasteful, considering the
low number of uses.  Fold both bits and deal with the little bit of
fallout.

Also take the liberty and drop dead code trying to set REX_B: No segment
register has RegRex set on it.

Additionally I was quite surprised that PUSH/POP with the permitted
segment registers is not covered by the test cases.  Add the missing
pieces.

41be57caf3 [gas][aarch64][SVE2] Fix pmull{t,b} requirement on SVE2-AES
I had mistakenly given all variants of the new SVE2 instructions
pmull{t,b} a dependency on the feature +sve2-aes.

Only the variant specifying .Q -> .D  sizes should have that
restriction.

This patch fixes that mistake and updates the testsuite to have extra
tests (matching the given set of tests per line in aarch64-tbl.h that
the rest of the SVE2 tests follow).

We also add a line in the documentation of the command line to clarify
how to enable `pmull{t,b}` of this larger size.  This is needed because
all other instructions gated under the `sve2-aes` architecture extension
are marked in the instruction documentation by an `HaveSVE2AES` check
while pmull{t,b} is gated under the `HaveSVE2PMULL128` check.

Regtested targeting aarch64-linux.

7cee18263c libctf: endianness fixes
Testing of the first code to generate CTF_K_SLICEs on big-endian
revealed a bunch of new problems in this area.  Most importantly, the
trick we did earlier to avoid wasting two bytes on padding in the
ctf_slice_t is best avoided: because it leads to the whole file after
that point no longer being naturally aligned, all multibyte accesses
from then on must use memmove() to avoid unaligned access on platforms
where that is fatal.  In future, this is planned, but for now we are
still doing direct access in many places, so we must revert to making
ctf_slice_t properly aligned for storage in an array.

Rather than wasting bytes on padding, we boost the size of cts_offset
and cts_bits.  This is still a waste of space (we cannot have offsets or
bits in bitfields > 256) but it cannot be avoided for now, and slices
are not so common that this will be a serious problem.

A possibly-worse endianness problem fixed at the same time involves
a codepath used only for foreign-endian, uncompressed CTF files, where
we were not copying the actual CTF data into the buffer, leading to
libctf reading only zeroes (or, possibly, uninitialized garbage).

Finally, when we read in a CTF file, we copy the header and work from
the copy.  We were flipping the endianness of the header copy, and of
the body of the file buffer, but not of the header in the file buffer
itself: so if we write the file back out again we end up with an
unreadable frankenfile with header and body of different endiannesses.
Fix by flipping both copies of the header.

include/
	* ctf.h (ctf_slice_t): Make cts_offset and cts_bits unsigned
	short, so following structures are properly aligned.

libctf/
	* ctf-open.c (get_vbytes_common): Return the new slice size.
	(ctf_bufopen): Flip the endianness of the CTF-section header copy.
	Remember to copy in the CTF data when opening an uncompressed
	foreign-endian CTF file.  Prune useless variable manipulation.

a0486bac41 libctf: fix a number of build problems found on Solaris and NetBSD
- Use of nonportable <endian.h>
- Use of qsort_r
- Use of zlib without appropriate magic to pull in the binutils zlib
- Use of off64_t without checking (fixed by dropping the unused fields
  that need off64_t entirely)
- signedness problems due to long being too short a type on 32-bit
  platforms: ctf_id_t is now 'unsigned long', and CTF_ERR must be
  used only for functions that return ctf_id_t
- One lingering use of bzero() and of <sys/errno.h>

All fixed, using code from gnulib where possible.

Relatedly, set cts_size in a couple of places it was missed
(string table and symbol table loading upon ctf_bfdopen()).

6dbf2b7340 libctf: labels
This facility allows you to associate regions of type IDs with *labels*,
a labelled tiling of the type ID space. You can use these to define
CTF containers with distinct parents for distinct ranges of the ID
space, or to assist with parallelization of CTF processing, or for any
other purpose you can think of.

Notably absent from here (though declared in the API header) is any way
to define new labels: this will probably be introduced soon, as part of
the linker deduplication work.  (One existed in the past, but was deeply
tied to the Solaris CTF file generator and had to be torn out.)

b437bfe0f4 libctf: lookups by name and symbol
These functions allow you to look up types given a name in a simple
subset of C declarator syntax (no function pointers), to look up the
types of variables given a name, and to look up the types of data
objects and the type signatures of functions given symbol table offsets.

(Despite its name, one function in this commit, ctf_lookup_symbol_name(),

316afdb130 libctf: core type lookup
Finally we get to the functions used to actually look up and enumerate
properties of types in a container (names, sizes, members, what type a
pointer or cv-qual references, determination of whether two types are
assignment-compatible, etc).

With a very few exceptions these do not work for types newly added via
ctf_add_*(): they only work on types in read-only containers, or types
added before the most recent call to ctf_update().

This also adds support for lookup of "variables" (string -> type ID
mappings) and for generation of C type names corresponding to a type ID.

143dce8481 libctf: ELF file opening via BFD
These functions let you open an ELF file with a customarily-named CTF
section in it, automatically opening the CTF file or archive and
associating the symbol and string tables in the ELF file with the CTF
container, so that you can look up the types of symbols in the ELF file
via ctf_lookup_by_symbol(), and so that strings can be shared between
the ELF file and CTF container, to save space.

It uses BFD machinery to do so.  This has now been lightly tested and
seems to work.  In particular, if you already have a bfd you can pass
it in to ctf_bfdopen(), and if you want a bfd made for you you can
call ctf_open() or ctf_fdopen(), optionally specifying a target (or
try once without a target and then again with one if you get
ECTF_BFD_AMBIGUOUS back).

We use a forward declaration for the struct bfd in ctf-api.h, so that
ctf-api.h users are not required to pull in <bfd.h>.  (This is mostly
for the sake of readelf.)

9402cc593f libctf: mmappable archives
If you need to store a large number of CTF containers somewhere, this
provides a dedicated facility for doing so: an mmappable archive format
like a very simple tar or ar without all the system-dependent format
horrors or need for heavy file copying, with built-in compression of
files above a particular size threshold.

libctf automatically mmap()s uncompressed elements of these archives, or
uncompresses them, as needed.  (If the platform does not support mmap(),
copying into dynamically-allocated buffers is used.)

Archive iteration operations are partitioned into raw and non-raw
forms. Raw operations pass thhe raw archive contents to the callback:
non-raw forms open each member with ctf_bufopen() and pass the resulting
ctf_file_t to the iterator instead.  This lets you manipulate the raw
data in the archive, or the contents interpreted as a CTF file, as
needed.

It is not yet known whether we will store CTF archives in a linked ELF
object in one of these (akin to debugdata) or whether they'll get one
section per TU plus one parent container for types shared between them.
(In the case of ELF objects with very large numbers of TUs, an archive
of all of them would seem preferable, so we might just use an archive,
and add lzma support so you can assume that .gnu_debugdata and .ctf are
compressed using the same algorithm if both are present.)

To make usage easier, the ctf_archive_t is not the on-disk
representation but an abstraction over both ctf_file_t's and archives of
many ctf_file_t's: users see both CTF archives and raw CTF files as
ctf_archive_t's upon opening, the only difference being that a raw CTF
file has only a single "archive member", named ".ctf" (the default if a
null pointer is passed in as the name).  The next commit will make use
of this facility, in addition to providing the public interface to
actually open archives.  (In the future, it should be possible to have
all CTF sections in an ELF file appear as an "archive" in the same
fashion.)

This machinery is also used to allow library-internal creators of
ctf_archive_t's (such as the next commit) to stash away an ELF string
and symbol table, so that all opens of members in a given archive will
use them.  This lets CTF archives exploit the ELF string and symbol
table just like raw CTF files can.

(All this leads to somewhat confusing type naming.  The ctf_archive_t is
a typedef for the opaque internal type, struct ctf_archive_internal: the
non-internal "struct ctf_archive" is the on-disk structure meant for
other libraries manipulating CTF files.  It is probably clearest to use
the struct name for struct ctf_archive_internal inside the program, and
the typedef names outside.)

72f3392127 libctf: opening
This fills in the other half of the opening/creation puzzle: opening of
already-existing CTF files.  Such files are always read-only: if you
want to add to a CTF file opened with one of the opening functions in
this file, use ctf_add_type(), in a later commit, to copy appropriate
types into a newly ctf_create()d, writable container.

The lowest-level opening functions are in here: ctf_bufopen(), which
takes ctf_sect_t structures akin to ELF section headers, and
ctf_simple_open(), which can be used if you don't have an entire ELF
section header to work from.  Both will malloc() new space for the
buffers only if necessary, will mmap() directly from the file if
requested, and will mprotect() it afterwards to prevent accidental
corruption of the types. These functions are also used by ctf_update()
when converting types in a writable container into read-only types that
can be looked up using the lookup functions (in later commits).

The files are always of the native endianness of the system that created
them: at read time, the endianness of the header magic number is used to
determine whether or not the file needs byte-swapping, and the entire
thing is aggressively byte-swapped.

The agggressive nature of this swapping avoids complicating the rest of
the code with endianness conversions, while the native endianness
introduces no byte-swapping overhead in the common case. (The
endianness-independence code is also much newer than everything else in
this file, and deserves closer scrutiny.)

The accessors at the top of the file are there to transparently support
older versions of the CTF file format, allowing translation from older
formats that have different sizes for the structures in ctf.h:
currently, these older formats are intermingled with the newer ones in
ctf.h: they will probably migrate to a compatibility header in time, to
ease readability.  The ctf_set_base() function is split out for the same
reason: when conversion code to a newer format is written, it would need
to malloc() new storage for the entire ctf_file_t if a file format
change causes it to grow, and for that we need ctf_set_base() to be a
separate function.

One pair of linked data structures supported by this file has no
creation code in libctf yet: the data and function object sections read
by init_symtab(). These will probably arrive soon, when the linker comes
to need them. (init_symtab() has hardly been changed since 2009, but if
any code in libctf has rotted over time, this will.)

A few simple accessors are also present that can even be called on
read-only containers because they don't actually modify them, since the
relevant things are not stored in the container but merely change its
operation: ctf_setmodel(), which lets you specify whether a container is
LP64 or not (used to statically determine the sizes of a few types),
ctf_import(), which is the only way to associate a parent container with
a child container, and ctf_setspecific(), which lets the caller
associate an arbitrary pointer with the CTF container for any use. If
the user doesn't call these functions correctly, libctf will misbehave:
this is particularly important for ctf_import(), since a container built
against a given parent container will not be able to resolve types that
depend on types in the parent unless it is ctf_import()ed with a parent
container with the same set of types at the same IDs, or a superset.

Possible future extensions (also noted in the ctf-hash.c file) include
storing a count of things so that we don't need to do one pass over the
CTF file counting everything, and computing a perfect hash at CTF
creation time in some compact form, storing it in the CTF file, and
using it to hash things so we don't need to do a second pass over the
entire CTF file to set up the hashes used to go from names to type IDs.
(There are multiple such hashes, one for each C type namespace: types,
enums, structs, and unions.)

47d546f427 libctf: creation functions
The CTF creation process looks roughly like (error handling elided):

int err;
ctf_file_t *foo = ctf_create (&err);

ctf_id_t type = ctf_add_THING (foo, ...);
ctf_update (foo);
ctf_*write (...);

Some ctf_add_THING functions accept other type IDs as arguments,
depending on the type: cv-quals, pointers, and structure and union
members all take other types as arguments.  So do 'slices', which
let you take an existing integral type and recast it as a type
with a different bitness or offset within a byte, for bitfields.
One class of THING is not a type: "variables", which are mappings
of names (in the internal string table) to types.  These are mostly
useful when encoding variables that do not appear in a symbol table
but which some external user has some other way to figure out the
address of at runtime (dynamic symbol lookup or querying a VM
interpreter or something).

You can snapshot the creation process at any point: rolling back to a
snapshot deletes all types and variables added since that point.

You can make arbitrary type queries on the CTF container during the
creation process, but you must call ctf_update() first, which
translates the growing dynamic container into a static one (this uses
the CTF opening machinery, added in a later commit), which is quite
expensive.  This function must also be called after adding types
and before writing the container out.

Because addition of types involves looking up existing types, we add a
little of the type lookup machinery here, as well: only enough to
look up types in dynamic containers under construction.

60da9d9559 libctf: lowest-level memory allocation and debug-dumping wrappers
The memory-allocation wrappers are simple things to allow malloc
interposition: they are only used inconsistently at present, usually
where malloc debugging was required in the past.

These provide a default implementation that is environment-variable
triggered (initialized on the first call to the libctf creation and
file-opening functions, the first functions people will use), and
a ctf_setdebug()/ctf_getdebug() pair that allows the caller to
explicitly turn debugging off and on.  If ctf_setdebug() is called,
the automatic setting from an environment variable is skipped.

2301ed1c9a aarch64: add STO_AARCH64_VARIANT_PCS and DT_AARCH64_VARIANT_PCS
The bottom 2 bits of st_other are used for visibility, the top 6 bits are
de facto reserved for processor specific use.  This patch defines a
bits to mark function symbols that follow a variant procedure call standard
with different register usage convention.

A dynamic tag is also defined that marks modules with R_<CLS>_JUMP_SLOT
relocations referencing symbols marked with STO_AARCH64_VARIANT_PCS.
This can be used by dynamic linkers that support lazy binding to decide
what registers need to be preserved during symbol resolution.

7ce2460a77 [binutils][aarch64] SVE2 feature extension flags.
Include all feature flag macros.

The "sve2" extension that enables the core sve2 instructions.
This also enables the sve extension, since sve is a requirement of sve2.

Extra optional sve2 features are the bitperm, sm4, aes, and sha3 extensions.
These are all given extra feature flags, "bitperm", "sve2-sm4",
"sve2-aes", and "sve2-sha3" respectively.
The sm4, aes, and sha3 extensions are explicitly marked as sve2
extensions to distinguish them from the corresponding NEON extensions.

Rather than continue extending the current feature flag numbers, I used
some bits that have been skipped.

This patch is part of a series of patches to add support for Armv8.1-M Mainline

This adds infrastructure for the BFCSEL instructions which is one of the first

The inconsistency between external R_ARM_THM_BF12 and internal
BFD_RELOC_ARM_THUMB_BF13 is because internally we count the static bit-0 of the

031254f211 [binutils, ARM, 1/16] Add support for Armv8.1-M Mainline CLI
The patch is straightforward, it does the following:

- support the new Tag_CPU_arch build attribute value, ie.:
   + declare the new value
   + update all the asserts forcing logic to be reviewed for new
     architectures
   + create a corresponding bfd_mach_arm_8_1M_MAIN enumerator in bfd and
     add mapping from Tag_CPU_arch to it
   + teach readelf about new Tag_CPU_arch value
- declare armv8.1-m.main as a supported architecture value
- define Armv8.1-M Mainline in terms of feature bits available
- tell objdump mapping from bfd_mach_arm_8_1M_MAIN enumerator to feature
   bits available
- update architecture-specific logic in gas and bfd guarded by the
   asserts mentioned above.
- tests for all the above

bd7ceb8d26 [BINUTILS, AArch64, 2/2] Update Store Allocation Tag instructions
This patch updates the Store allocation tags instructions in
Armv8.5-A Memory Tagging Extension. This is part of the changes
that have been introduced recently in the 00bet10 release

All of these instructions have an updated register operand (Xt -> <Xt|SP>)

- STG <Xt|SP>, [<Xn|SP>, #<simm>]
- STG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STG <Xt|SP>, [<Xn|SP>], #<simm>
- STZG <Xt|SP>, [<Xn|SP>, #<simm>]
- STZG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZG <Xt|SP>, [<Xn|SP>], #<simm>
- ST2G <Xt|SP>, [<Xn|SP>, #<simm>]
- ST2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- ST2G <Xt|SP>, [<Xn|SP>], #<simm>
- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]
- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZ2G <Xt|SP>, [<Xn|SP>], #<simm>

In order to accept <Rt|SP> a new operand type Rt_SP is introduced which has
the same field as FLD_Rt but follows other semantics of Rn_SP.

34ef62f465 [GAS, Arm] CLI with architecture sensitive extensions
This patch adds a new framework to add architecture sensitive extensions, like
GCC does.  This patch also implements all architecture extensions currently
available in GCC.

This framework works as follows.  To enable architecture sensitive extensions
for a particular architecture, that architecture must contain an ARM_ARCH_OPT2
entry in the 'arm_archs' table.  All fields here are the same as previous, with
the addition of a new extra field at the end to <name> it's extension table.
This <name>, corresponds to a <name>_ext_table of type 'struct arm_ext_table'.
This struct can be filled with three types of entries:

  ARM_ADD (string <ext>, arm_feature_set <enable_bits>), which means +<ext> will
      enable <enable_bits>
  ARM_REMOVE (string <ext>, arm_feature_set <disable_bits>), which means
      +no<ext> will disable <disable_bits>
  ARM_EXT (string <ext>, arm_feature_set <enable_bits>, arm_feature_set
      <disable_bits>), which means +<ext> will enable <enable_bits> and +no<ext>
      will disable <disable_bits> (this is to be used instead of adding an
      ARM_ADD and ARM_REMOVE for the same <ext>)

This patch does not disable the use of the old extensions, even if some of them
are duplicated in the new tables.  This is a "in-between-step" as we may want to
deprecate the old table of extensions in later patches.  For now, GAS will first
look for the +<ext> or +no<ext> in the new table and if no entry is found it
will continue searching in the old table, following old behaviour.  If only an
ARM_ADD or an ARM_REMOVE is defined for <ext> and +no<ext> or +<ext> resp. is
used then it also continues to search the old table for it.

A couple of caveats:
- This patch does not enable the use of these architecture extensions with the
'.arch_extension' directive.  This is future work that I will tend to later.
- This patch does not enable the use of these architecture extensions with the
-mcpu option.  This is future work that I will tend to later.
- This patch does not change the current behaviour when combining an
architecture extension and using -mfpu on the command-line.  The current
behaviour of GAS is to stage the union of feature bits enabled by both -march
and -mfpu.  GCC behaves differently here, so this is something we may want to
revisit on a later date.
