MSP430: Support relocations for subtract expressions in .uleb128 directives
Link-time relaxations of branches are common for MSP430, given that GCC
can generate pessimal branch instructions, and the
-mcode-region=either/-mdata-region=either options to shuffle sections
can further change the type of branch instruction required.
These relaxations can result in invalid code when .uleb128
directives, used in the .gcc_except_table section, are used to calculate
the distance between two labels. A value for the .uleb128 directive is
calculated at assembly-time, and can't be updated at link-time, even if
relaxation causes the distance between the labels to change.
This patch adds relocations for subtract expressions in .uleb128
directives, to allow the linker to re-calculate the value of these
expressions after relaxation has been performed.

libctf, binutils, include, ld: gettextize and improve error handling
This commit follows on from the earlier commit "libctf, ld, binutils:
add textual error/warning reporting for libctf" and converts every error
in libctf that was reported using ctf_dprintf to use ctf_err_warn
instead, gettextizing them in the process, using N_() where necessary to
avoid doing gettext calls unless an error message is actually generated,
and rephrasing some error messages for ease of translation.
This requires a slight change in the ctf_errwarning_next API: this API
is public but has not been in a release yet, so can still change freely.
The problem is that many errors are emitted at open time (whether
opening of a CTF dict, or opening of a CTF archive): the former of these
throws away its incompletely-initialized ctf_file_t rather than return
it, and the latter has no ctf_file_t at all. So errors and warnings
emitted at open time cannot be stored in the ctf_file_t, and have to go
elsewhere.
We put them in a static local in ctf-subr.c (which is not very
thread-safe: a later commit will improve things here): ctf_err_warn with
a NULL fp adds to this list, and the public interface
ctf_errwarning_next with a NULL fp retrieves from it.
We need a slight exception from the usual iterator rules in this case:
with a NULL fp, there is nowhere to store the ECTF_NEXT_END "error"
which signifies the end of iteration, so we add a new err parameter to
ctf_errwarning_next which is used to report such iteration-related
errors. (If an fp is provided -- i.e., if not reporting open errors --
this is optional, but even if it's optional it's still an API change.
This is actually useful from a usability POV as well, since
ctf_errwarning_next is usually called when there's been an error, so
overwriting the error code with ECTF_NEXT_END is not very helpful!
So, unusually, ctf_errwarning_next now uses the passed fp for its
error code *only* if no errp pointer is passed in, and leaves it
untouched otherwise.)
ld, objdump and readelf are adapted to call ctf_errwarning_next with a
NULL fp to report open errors where appropriate.
The ctf_err_warn API also has to change, gaining a new error-number
parameter which is used to add the error message corresponding to that
error number into the debug stream when LIBCTF_DEBUG is enabled:
changing this API is easy at this point since we are already touching
all existing calls to gettextize them. We need this because the debug
stream should contain the errno's message, but the error reported in the
error/warning stream should *not*, because the caller will probably
report it themselves at failure time regardless, and reporting it in
every error message that leads up to it leads to a ridiculous chattering
on failure, which is likely to end up as ridiculous chattering on stderr
(trimmed a bit):
CTF error: `ld/testsuite/ld-ctf/A.c (0): lookup failure for type 3: flags 1: The parent CTF dictionary is unavailable'
CTF error: `ld/testsuite/ld-ctf/A.c (0): struct/union member type hashing error during type hashing for type 80000001, kind 6: The parent CTF dictionary is unavailable'
CTF error: `deduplicating link variable emission failed for ld/testsuite/ld-ctf/A.c: The parent CTF dictionary is unavailable'
ld/.libs/lt-ld-new: warning: CTF linking failed; output will have no CTF section: `The parent CTF dictionary is unavailable'
We only need to be told that the parent CTF dictionary is unavailable
*once*, not over and over again!
errmsgs are still emitted on warning generation, because warnings do not
usually lead to a failure propagated up to the caller and reported
there.
Debug-stream messages are not translated. If translation is turned on,
there will be a mixture of English and translated messages in the debug
stream, but rather that than burden the translators with debug-only
output.

libctf, link: tie in the deduplicating linker
This fairly intricate commit connects up the CTF linker machinery (which
operates in terms of ctf_archive_t's on ctf_link_inputs ->
ctf_link_outputs) to the deduplicator (which operates in terms of arrays
of ctf_file_t's, all the archives exploded).
The nondeduplicating linker is retained, but is not called unless the
CTF_LINK_NONDEDUP flag is passed in (which ld never does), or the
environment variable LD_NO_CTF_DEDUP is set. Eventually, once we have
confidence in the much-more-complex deduplicating linker, I hope the
nondeduplicating linker can be removed.
In brief, what this does is traverses each input archive in
ctf_link_inputs, opening every member (if not already open) and tying
child dicts to their parents, shoving them into an array and
constructing a corresponding parents array that tells the deduplicator
which dict is the parent of which child. We then call ctf_dedup and
ctf_dedup_emit with that array of inputs, taking the outputs that result
and putting them into ctf_link_outputs where the rest of the CTF linker
expects to find them, then linking in the variables just as is done by
the nondeduplicating linker.
It also implements much of the CU-mapping side of things. The problem
CU-mapping introduces is that if you map many input CUs into one output,
this is saying that you want many translation units to produce at most
one child dict if conflicting types are found in any of them. This
means you can suddenly have multiple distinct types with the same name
in the same dict, which libctf cannot really represent because it's not
something you can do with C translation units.
The deduplicator machinery already committed does as best it can with
these, hiding types with conflicting names rather than making child
dicts out of them: but we still need to call it. This is done similarly
to the main link, taking the inputs (one CU output at a time),
deduplicating them, taking the output and making it an input to the
final link. Two (significant) optimizations are done: we share atoms
tables between all these links and the final link (so e.g. all type hash
values are shared, all decorated type names, etc); and any CU-mapped
links with only one input (and no child dicts) doesn't need to do
anything other than renaming the CU: the CU-mapped link phase can be
skipped for it. Put together, large CU-mapped links can save 50% of
their memory usage and about as much time (and the memory usage for
CU-mapped links is significant, because all those output CUs have to
have all their types stored in memory all at once).

libctf, link: redo cu-mapping handling
Now a bunch of stuff that doesn't apply to ld or any normal use of
libctf, piled into one commit so that it's easier to ignore.
The cu-mapping machinery associates incoming compilation unit names with
outgoing names of CTF dictionaries that should correspond to them, for
non-gdb CTF consumers that would like to group multiple TUs into a
single child dict if conflicting types are found in it (the existing use
case is one kernel module, one child CTF dict, even if the kernel module
is composed of multiple CUs).
The upcoming deduplicator needs to track not only the mapping from
incoming CU name to outgoing dict name, but the inverse mapping from
outgoing dict name to incoming CU name, so it can work over every CTF
dict we might see in the output and link into it.
So rejig the ctf-link machinery to do that. Simultaneously (because
they are closely associated and were written at the same time), we add a
new CTF_LINK_EMPTY_CU_MAPPINGS flag to ctf_link, which tells the
ctf_link machinery to create empty child dicts for each outgoing CU
mapping even if no CUs that correspond to it exist in the link. This is
a bit (OK, quite a lot) of a waste of space, but some existing consumers
require it. (Nobody else should use it.)
Its value is not consecutive with existing CTF_LINK flag values because
we're about to add more flags that are conceptually closer to the
existing ones than this one is.

libctf, link: add lazy linking: clean up input members: err/warn cleanup
This rather large and intertwined pile of changes does three things:
First, it transitions from dprintf to ctf_err_warn for things the user might
care about: this one file is the major impetus for the ctf_err_warn
infrastructure, because things like file names are crucial in linker
error messages, and errno values are utterly incapable of
communicating them
Second, it stabilizes the ctf_link APIs: you can now call
ctf_link_add_ctf without a CTF argument (only a NAME), to lazily
ctf_open the file with the given NAME when needed, and close it as soon
as possible, to save memory. This is not an API change because a null
CTF argument was prohibited before now.
Since getting CTF directly from files uses ctf_open, passing in only a
NAME requires use of libctf, not libctf-nobfd. The linker's behaviour
is unchanged, as it still passes in a ctf_archive_t as before.
This also let us fix a leak: we were opening ctf_archives and their
containing ctf_files, then only closing the files and leaving the
archives open.
Third, this commit restructures the ctf_link_in_member argument used by
the CTF linking machinery and adjusts its users accordingly.
We drop two members:
- arcname, which is difficult to construct and then only used in error
messages (that were only dprintf()ed, so never seen!)
- share_mode, since we store the flags passed to ctf_link (including the
share mode) in a new ctf_file_t.ctf_link_flags to help dedup get hold
of it
We rename others whose existing names were fairly dreadful:
- done_main_member -> done_parent, using consistent terminology for .ctf
as the parent of all archive members
- main_input_fp -> in_fp_parent, likewise
- file_name -> in_file_name, likewise
We add one new member, cu_mapped.
Finally, we move the various frees of things like mapping table data to
the top-level ctf_link, since deduplicating links will want to do that
too.

libctf, ld, binutils: add textual error/warning reporting for libctf
This commit adds a long-missing piece of infrastructure to libctf: the
ability to report errors and warnings using all the power of printf,
rather than being restricted to one errno value. Internally, libctf
calls ctf_err_warn() to add errors and warnings to a list: a new
iterator ctf_errwarning_next() then consumes this list one by one and
hands it to the caller, which can free it. New errors and warnings are
added until the list is consumed by the caller or the ctf_file_t is
closed, so you can dump them at intervals. The caller can of course
choose to print only those warnings it wants. (I am not sure whether we
want objdump, readelf or ld to print warnings or not: right now I'm
printing them, but maybe we only want to print errors? This entirely
depends on whether warnings are voluminous things describing e.g. the
inability to emit single types because of name clashes or something.
There are no users of this infrastructure yet, so it's hard to say.)
There is no internationalization here yet, but this at least adds a
place where internationalization can be added, to one of
ctf_errwarning_next or ctf_err_warn.
We also provide a new ctf_assert() function which uses this
infrastructure to provide non-fatal assertion failures while emitting an
assert-like string to the caller: to save space and avoid needlessly
duplicating unchanging strings, the assertion test is inlined but the
print-things-out failure case is not. All assertions in libctf will be
converted to use this machinery in future commits and propagate
assertion-failure errors up, so that the linker in particular cannot be
killed by libctf assertion failures when it could perfectly well just
print warnings and drop the CTF section.

libctf, next: introduce new class of easier-to-use iterators
The libctf machinery currently only provides one way to iterate over its
data structures: ctf_*_iter functions that take a callback and an arg
and repeatedly call it.
This *works*, but if you are doing a lot of iteration it is really quite
inconvenient: you have to package up your local variables into
structures over and over again and spawn lots of little functions even
if it would be clearer in a single run of code. Look at ctf-string.c
for an extreme example of how unreadable this can get, with
three-line-long functions proliferating wildly.
The deduplicator takes this to the Nth level. It iterates over a whole
bunch of things: if we'd had to use _iter-class iterators for all of
them there would be twenty additional functions in the deduplicator
alone, for no other reason than that the iterator API requires it.
Let's do something better. strtok_r gives us half the design: generators
in a number of other languages give us the other half.
The *_next API allows you to iterate over CTF-like entities in a single
function using a normal while loop. e.g. here we are iterating over all
the types in a dict:
ctf_next_t *i = NULL;
int *hidden;
ctf_id_t id;
while ((id = ctf_type_next (fp, &i, &hidden, 1)) != CTF_ERR)
{
/* do something with 'hidden' and 'id' */
}
if (ctf_errno (fp) != ECTF_NEXT_END)
/* iteration error */
Here we are walking through the members of a struct with CTF ID
'struct_type':
ctf_next_t *i = NULL;
ssize_t offset;
const char *name;
ctf_id_t membtype;
while ((offset = ctf_member_next (fp, struct_type, &i, &name,
&membtype)) >= 0
{
/* do something with offset, name, and membtype */
}
if (ctf_errno (fp) != ECTF_NEXT_END)
/* iteration error */
Like every other while loop, this means you have access to all the local
variables outside the loop while inside it, with no need to tiresomely
package things up in structures, move the body of the loop into a
separate function, etc, as you would with an iterator taking a callback.
ctf_*_next allocates 'i' for you on first entry (when it must be NULL),
and frees and NULLs it and returns a _next-dependent flag value when the
iteration is over: the fp errno is set to ECTF_NEXT_END when the
iteartion ends normally. If you want to exit early, call
ctf_next_destroy on the iterator. You can copy iterators using
ctf_next_copy, which copies their current iteration position so you can
remember loop positions and go back to them later (or ctf_next_destroy
them if you don't need them after all).
Each _next function returns an always-likely-to-be-useful property of
the thing being iterated over, and takes pointers to parameters for the
others: with very few exceptions all those parameters can be NULLs if
you're not interested in them, so e.g. you can iterate over only the
offsets of members of a structure this way:
while ((offset = ctf_member_next (fp, struct_id, &i, NULL, NULL)) >= 0)
If you pass an iterator in use by one iteration function to another one,
you get the new error ECTF_NEXT_WRONGFUN back; if you try to change
ctf_file_t in mid-iteration, you get ECTF_NEXT_WRONGFP back.
Internally the ctf_next_t remembers the iteration function in use,
various sizes and increments useful for almost all iterations, then
uses unions to overlap the actual entities being iterated over to keep
ctf_next_t size down.
Iterators available in the public API so far (all tested in actual use
in the deduplicator):
/* Iterate over the members of a STRUCT or UNION, returning each member's
offset and optionally name and member type in turn. On end-of-iteration,
returns -1. */
ssize_t
ctf_member_next (ctf_file_t *fp, ctf_id_t type, ctf_next_t **it,
const char **name, ctf_id_t *membtype);
/* Iterate over the members of an enum TYPE, returning each enumerand's
NAME or NULL at end of iteration or error, and optionally passing
back the enumerand's integer VALue. */
const char *
ctf_enum_next (ctf_file_t *fp, ctf_id_t type, ctf_next_t **it,
int *val);
/* Iterate over every type in the given CTF container (not including
parents), optionally including non-user-visible types, returning
each type ID and optionally the hidden flag in turn. Returns CTF_ERR
on end of iteration or error. */
ctf_id_t
ctf_type_next (ctf_file_t *fp, ctf_next_t **it, int *flag,
int want_hidden);
/* Iterate over every variable in the given CTF container, in arbitrary
order, returning the name and type of each variable in turn. The
NAME argument is not optional. Returns CTF_ERR on end of iteration
or error. */
ctf_id_t
ctf_variable_next (ctf_file_t *fp, ctf_next_t **it, const char **name);
/* Iterate over all CTF files in an archive, returning each dict in turn as a
ctf_file_t, and NULL on error or end of iteration. It is the caller's
responsibility to close it. Parent dicts may be skipped. Regardless of
whether they are skipped or not, the caller must ctf_import the parent if
need be. */
ctf_file_t *
ctf_archive_next (const ctf_archive_t *wrapper, ctf_next_t **it,
const char **name, int skip_parent, int *errp);

libctf: restructure error handling to reduce relocations
Jose Marchesi noted that the traditional-Unix error array in ctf-error.c
introduces one reloc per error to initialize the array: 58 so far. We
can reduce this to zero using an array of carefully-sized individual
members which is used to construct a string table, that is then
referenced by the lookup functions: but doing this automatically is a
pain.
Bruno Haible wrote suitable code years ago: I got permission to reuse it
(Bruno says "... which I hereby put in the public domain"); I modified
it a tiny bit (similarly to what Ulrich Drepper did in the dsohowto
text, but I redid it from scratch), commented it up a bit, and shifted
the error table into that form, migrating it into the new file
ctf-error.h.
This has the advantage that it spotted both typos in the text of the
errors in the comments in ctf-api.h and typos in the error defines in
the comments in ctf-error.c, and places where the two were simply not
in sync. All are now fixed.
One new constant exists in ctf-api.h: CTF_NERR, since the old method of
working out the number of errors in ctf-error.c was no longer usable,
and it seems that the number of CTF errors is something users might
reasonably want as well. It should be pretty easy to keep up to date as
new errors are introduced.

libctf, binutils: support CTF archives like objdump
objdump and readelf have one major CTF-related behavioural difference:
objdump can read .ctf sections that contain CTF archives and extract and
dump their members, while readelf cannot. Since the linker often emits
CTF archives, this means that readelf intermittently and (from the
user's perspective) randomly fails to read CTF in files that ld emits,
with a confusing error message wrongly claiming that the CTF content is
corrupt. This is purely because the archive-opening code in libctf was
needlessly tangled up with the BFD code, so readelf couldn't use it.
Here, we disentangle it, moving ctf_new_archive_internal from
ctf-open-bfd.c into ctf-archive.c and merging it with the helper
function in ctf-archive.c it was already using. We add a new public API
function ctf_arc_bufopen, that looks very like ctf_bufopen but returns
an archive given suitable section data rather than a ctf_file_t: the
archive is a ctf_archive_t, so it can be called on raw CTF dictionaries
(with no archive present) and will return a single-member synthetic
"archive".
There is a tiny lifetime tweak here: before now, the archive code could
assume that the symbol section in the ctf_archive_internal wrapper
structure was always owned by BFD if it was present and should always be
freed: now, the caller can pass one in via ctf_arc_bufopen, wihch has
the usual lifetime rules for such sections (caller frees): so we add an
extra field to track whether this is an internal call from ctf-open-bfd,
in which case we still free the symbol section.

RISC-V: Report warning when linking the objects with different priv specs.
We do know some conflicts among different privileged specs. For linker,
the safest approach is that don't allow the object linked with others which
may cause conflicts. But this may cause inconvenience since not all objects
with conflicting priv specs are linked will cause problems. But it is hard
to know the detailed conflict cases for linker, so we probably need a option
to tell linker that we do know there are no conflicts, or we are willing to
take risks to link the objects with conflicted priv specs. But the option
is still under discussion.
Therefore, we can report warnings rather than errors when linking the objects
with conflicted priv specs. This not only makes the linker more flexible,
but also warns people that the conflicts may happen. We also need to update
the output priv spec version once the input priv spec is newer.

RISC-V: Drop the privileged spec v1.9 support.
There is a conflict between v1.9 and v1.9.1 - CSR MISA address. MISA is
0xf10 in v1.9, but change to 0x301 in v1.9.1. The change made MISA writable,
but may also cause risk of compatibility. Binutils already support the
-mpriv-spec options and ELF priv attributes, which can used to choose what
privileged spec you want, and then give a correponding CSR name and address
to use. But Gdb and other tools don't have the simialr mechanism for now.
However, there are two things can be confirmed,
1. If we don't have a way to control the priv specs, then the changes, like
MISA, will cause risk and hard to maintain.
2. We get the guarantee that the CSR address won't be reused in the future
specs, even if it is dropped.
I'm not sure if Gdb needs to care about the priv spec versions, it is still
discussing. But drop the priv spec v1.9, and make sure that we won't reuse
the CSR address is a useful solution for now. Also, we might drop the v1.9.1
in a year or two. After that, specs above v1.10 should be compatible anyway.

opcodes: discriminate endianness and insn-endianness in CGEN ports
The CGEN support code in opcodes accesses instruction contents using a
couple of functions defined in cgen-opc.c: cgen_get_insn_value and
cgen_put_insn_value. These functions use the "instruction endianness"
in the CPU description to order the read/written bytes.
The process of writing an instruction to the object file is:
a) cgen_put_insn_value ;; Writes out the opcodes.
b) ARCH_cgen_insert_operand
insert_normal
insert_1
cgen_put_insn_value ;; Writes out the bytes of the
;; operand.
Likewise, the process of reading an instruction from the object file
is:
a) cgen_get_insn_value ;; Reads the opcodes.
b) ARCH_cgen_extract_operand
extract_normal
extract_1
cgen_get_insn_value ;; Reads in the bytes of the
;; operand.
As can be seen above, cgen_{get,put}_insn_value are used to both
process the instruction opcodes (the constant fields conforming the
base instruction) and also the values of the instruction operands,
such as immediates.
This is problematic for architectures in which the endianness of
instructions is different to the endianness of data. An example is
BPF, where instructions are always encoded big-endian but the data may
be either big or little.
This patch changes the cgen_{get,put}_insn_value functions in order to
get an extra argument with the endianness to use, and adapts the
existin callers to these functions in order to provide cd->endian or
cd->insn_endian, whatever appropriate. Callers like extract_1 and
insert_1 pass cd->endian (since they are reading/writing operand
values) while callers reading/writing the base instruction pass
cd->insn_endian instead.
A few little adjustments have been needed in some existing CGEN based
ports:
* The BPF assembler uses cgen_put_insn_value. It has been adapted to
pass the new endian argument.
* The mep port has code in mep.opc that uses cgen_{get,put}_insn_value.
It has been adapted to pass the new endianargument. Ditto for a
call in the assembler.
Tested with --enable-targets=all.
Regested in all supported targets.
No regressions.

[PATCH v2 0/9] RISC-V: Support version controling for ISA standard extensions and CSR
1. Remove the -mriscv-isa-version and --with-riscv-isa-version options.
We can still use -march to choose the version for each extensions, so there is
no need to add these.
2. Change the arguments of options from [1p9|1p9p1|...] to [1.9|1.9.1|...].
Unlike the architecture string has specified by spec, ther is no need to do
the same thing for options.
3. Spilt the patches to reduce the burdens of review.
[PATCH 3/7] RISC-V: Support new GAS options and configure options to set ISA versions
to
[PATCH v2 3/9] RISC-V: Support GAS option -misa-spec to set ISA versions
[PATCH v2 4/9] RISC-V: Support configure options to set ISA versions by default.
[PATCH 4/7] RISC-V: Support version checking for CSR according to privilege version.
to
[PATCH v2 5/9] RISC-V: Support version checking for CSR according to privilege spec version.
[PATCH v2 6/9] RISC-V: Support configure option to choose the privilege spec version.
4. Use enum class rather than string to compare the choosen ISA spec in opcodes/riscv-opc.c.
The behavior is same as comparing the choosen privilege spec.
include * opcode/riscv.h: Include "bfd.h" to support bfd_boolean.
(enum riscv_isa_spec_class): New enum class. All supported ISA spec
belong to one of the class
(struct riscv_ext_version): New structure holds version information
for the specific ISA.
* opcode/riscv-opc.h (DECLARE_CSR): There are two version information,
define_version and abort_version. The define_version means which
privilege spec is started to define the CSR, and the abort_version
means which privilege spec is started to abort the CSR. If the CSR is
valid for the newest spec, then the abort_version should be
PRIV_SPEC_CLASS_DRAFT.
(DECLARE_CSR_ALIAS): Same as DECLARE_CSR, but only for the obselete CSR.
* opcode/riscv.h (enum riscv_priv_spec_class): New enum class. Define
the current supported privilege spec versions.
(struct riscv_csr_extra): Add new fields to store more information
about the CSR. We use these information to find the suitable CSR
address when user choosing a specific privilege spec.
binutils * dwarf.c: Updated since DECLARE_CSR is changed.
opcodes * riscv-opc.c (riscv_ext_version_table): The table used to store
all information about the supported spec and the corresponding ISA
versions. Currently, only Zicsr is supported to verify the
correctness of Z sub extension settings. Others will be supported
in the future patches.

privilege spec class by giving a spec string.
(riscv_get_priv_spec_name): New function. Get the corresponding
privilege spec string by giving a CSR version class.

according to the chosen version. Build a hash table riscv_csr_hash to
store the valid CSR for the chosen pirv verison. Dump the direct
CSR address rather than it's name if it is invalid.
(parse_riscv_dis_option_without_args): New function. Parse the options
without arguments.
(parse_riscv_dis_option): Call parse_riscv_dis_option_without_args to

get_default_version. It is used to find the default version for
the specific extension.

already set it's version to 2p1 by march, so no need to use the default
2p2 version. For m-ext, we do not set the version by -march and ELF arch
attribute, so set the default 2p0 to it. For zicsr, it is not defined in
ISA spec 2p2, so set 0p0 to it.

to check the ISA dependency for CSR, so fix the spec version by adding
-mpriv-spec=1.11.

xtensa: fix PR ld/25861
Introduce new relaxations XTENSA_PDIFF{8,16,32} for positive differences
(subtracted symbol precedes diminished symbol) and XTENSA_NDIFF{8,16,32}
for negative differences (subtracted symbol follows diminished symbol).
Don't generate XTENSA_DIFF relocations in the assembler, generate
XTENSA_PDIFF or XTENSA_NDIFF based on relative symbol position.
Handle XTENSA_DIFF in BFD for compatibility with old object files.
Handle XTENSA_PDIFF and XTENSA_NDIFF in BFD, treating difference value
as unsigned.

coff-go32-exe: support variable-length stubs
The stub size in GO32 executables has historically been fixed at 2048
bytes, due to hardcoded limitations in bfd. Recent patches to djgpp by
Stas Sergeev (CC'd) have pushed the stub right up to this limit, so if
any further expansion is desired, this must first be patched in bfd.
This series includes three patches: The first changes the meaning of
the bfd->origin field slightly, so that target code can use this to
specify an offset into the file where the actual bfd is located.
The second patch then uses this to enable support for variable-sized
stubs in the coff-go32-exe format.
The final patch is only a cleanup, it normalizes function and variable
names in coff-stgo32.c so that they all begin with the same prefix.

bfd->origin to file offset.

RISC-V: Support the ISA-dependent CSR checking.
According to the riscv privilege spec, some CSR are only valid when rv32 or
the specific extension is set. We extend the DECLARE_CSR and DECLARE_CSR_ALIAS
to record more informaton we need, and then check whether the CSR is valid
according to these information. We report warning message when the CSR is
invalid, so we have a choice between error and warning by --fatal-warnings
option. Also, a --no-warn/-W option is used to turn the warnings off, if
people don't want the warnings.

[binutils][arm] arm support for ARMv8.m Custom Datapath Extension
This patch is part of a series that adds support for the Armv8.m
ARMv8.m Custom Datapath Extension to binutils.
This patch introduces the Custom Instructions Class 1/2/3 (Single/
Dual, Accumulator/Non-accumulator varianats) to the arm backend.
The following Custom Instructions are added: cx1, cx1a,
cx1d, cx1da, cx2, cx2a, cx2d, cx2da, cx3, cx3a, cx3d, cx3da.
Specification can be found at
https://developer.arm.com/docs/ddi0607/latest
This patch distinguishes between enabling CDE for different coprocessor
numbers by defining multiple architecture flags. This means that the
parsing of the architecture extension flags is kept entirely in the
existing code path.
We introduce a new IT block state to indicate the behaviour of these
instructions. This new state allows being used in an IT block or
outside an IT block, but does not allow the instruction to be used
inside a VPT block.
We need this since the CX*A instruction versions can be used in IT
blocks, but they aren't to have the conditional suffixes on them. Hence
we need to mark an instruction as allowed in either position.
