Use unsupported in 'require'
This changes 'require' to use 'unsupported' rather than 'untested'.
The latter doesn't really seem to be correct according to the DejaGNU
documentation:
Declares a test was not run. `untested' writes in the log file a
message beginning with _UNTESTED_, appending the `message' argument.
For example, you might use this in a dummy test whose only role is to
record that a test does not yet exist for some feature.
The example there, and some text elsewhere, is what makes me think
this isn't a great fit. On the other hand, 'unsupported' says:
Declares that a test case depends on some facility that does not exist
in the testing environment.

ARM: Fix ld bloat introduced between binutils-2.38 and 2.39
Since commit
9833b7757d24, "PR28824, relro security issues",
ELF_MAXPAGESIZE matters much more, with regards to layout of
the linked file. That commit fixed an actual bug, but also
exposes a problem for targets were that value is too high.
For example, for ARM(32, a.k.a. "Aarch32") specifically
bfd_arch_arm, it's set to 64 KiB, making all Linux(/GNU)
targets pay an extra amount of up to 60 KiB of bloat in
DSO:s and executables. This matters when there are many
such files, and where storage is expensive.
It's *mostly* bloat when using a Linux kernel, as ARM(32) is
a good example of an target where ELF_MAXPAGESIZE is set to
an extreme value for an obscure corner-case. The ARM
(32-bit) kernel has 4 KiB pages, has had that value forever,
and can't be configured to any other value. The use-case is
IIUC "Aarch32" emulation on an "Aarch64" (arm64) kernel, but
not just that, but a setup where the Linux page-size is
configured to something other than the *default* 4 KiB. Not
sure there actually any such systems in use, again with
both Aarch32 compatibility support and a non-4KiB pagesize,
with all the warnings in the kernel config and requiring the
"EXPERT" level set on.
So, let's do like x86-64 in
a2267dbfc9e1 "x86-64: Use only
one default max-page-size" and set ELF_MAXPAGESIZE to 4096.
bfd:
* elf32-arm.c (ELF_MAXPAGESIZE): Always set to 0x1000.

ld/testsuite: Adjust for ELF_MAXPAGESIZE 0x1000

libctf: ctf-link outdated input check faulty
This check has a pair of faults which, combined, can lead to memory
corruption. Firstly, it assumes that the values of the ctf_link_inputs
hash are ctf_dict_t's: they are not, they are ctf_link_input_t's, a much
shorter structure. So the flags check which is the core of this is
faulty (but happens, by chance, to give the right output on most
architectures, since usually we happen to get a 0 here, so the test that
checks this usually passes). Worse, the warning that is emitted when
the test fails is added to the wrong dict -- it's added to the input
dict, whose warning list is never consumed, rendering the whole check
useless. But the dict it adds to is still the wrong type, so we end up
overwriting something deep in memory (or, much more likely,
dereferencing a garbage pointer and crashing).
Fixing both reveals another problem: the link input is an *archive*
consisting of multiple members, so we have to consider whether to check
all of them for the outdated-func-info thing we are checking here.
However, no compiler exists that emits a mixture of members with this
flag on and members with it off, and the linker always reserializes (and
upgrades) such things when it sees them: so all members in a given
archive must have the same value of the flag, so we only need to check
one member per input archive.

libctf: skip the testsuite from inside dejagnu
The libctf testsuite uses Tcl try/catch to trap run_output errors. This
is only supported in reasonably recent Tcls, so we detect the lack of
try/catch and suppress the testsuite via an Automake conditional in its
absence.
But this turns out not to work: Automake produces a check-DEJAGNU target
regardless of the value of this conditional and sticks it in an
unconditionally-executed part of the makefile, so the testsuite gets
executed anyway, and fails with a nasty-looking syntax error. We can't
disable it by taking "dejagnu" out of AUTOMAKE_OPTIONS, because if you
do that Automake stops you using RUNTEST, RUNTESTFLAGS and other
variables users would expect to work.
So move to disabling the testsuite from inside the testsuite itself,
importing the value of the former Automake conditional as a Tcl variable
and exiting very early in default.exp if it's false.

Fix size of external_reloc for pe-aarch64
This patch series finishes off the work by Jedidiah Thompson, and adds
support for creating aarch64 PE images.
This should be essentially complete: I've used this to create a "hello
world" Windows program in asm, and (with GCC patches) a UEFI program in
C. I think the only things missing are the .secidx relocation, which is
needed for PDBs, and the SEH pseudos used for C++ exceptions.
This first patch fixes the size of RELSZ; I'm not sure why it was 14 in
the first place. This is the size of the "Base Relocation Block" in
https://learn.microsoft.com/en-us/windows/win32/debug/pe-format, and
AFAIK should be 10 for everything.

gdb/dwarf2: Fix 'rw_pieced_value' for values casted to different type.
The 'rw_pieced_value' function is executed when fetching a (lazy)
variable described by 'DW_OP_piece' or 'DW_OP_bit_piece'. The
function checks the 'type' and 'enclosing_type' fields of the value
for identity.
* The 'type' field describes the type of a value.
* In most cases, the 'enclosing_type' field is identical to the
'type' field.
* Scenarios where the 'type' and 'enclosing_type' of an object
differ are described in 'gdb/value.c'. Possible cases are:
* If a value represents a C++ object, then the 'type' field
gives the object's compile-time type. If the object actually
belongs to some class derived from `type', perhaps with other
base classes and additional members, then `type' is just a
subobject of the real thing, and the full object is probably
larger than `type' would suggest.
* If 'type' is a dynamic class (i.e. one with a vtable), then GDB
can actually determine the object's run-time type by looking at
the run-time type information in the vtable. GDB may then elect
to read the entire object.
* If the user casts a variable to a different type
(e.g. 'print (<type> []) <variable>'), the value's type is
updated before reading the value.
If a lazy value is fetched, GDB allocates space based on the enclosing
type's length and typically reads the 'full' object. This is not
implemented for pieced values and causes an internal error if 'type'
and 'enclosing_type' of a value are not identical.
However, GDB can read the value based on its type. Thus, this patch
fixes the previously mentioned cases by removing the check for identity.
