982d0151e9 PR ld/21375: MIPS: Add test cases for undefined weaks resolving to zero
Define a new procedure, `run_mips_undefweak_test', and use it to iterate
over several scenarios involving undefined weak symbols resolving to
zero, verifying expected regular MIPS, MIPS16 and microMIPS code, GOT
and dynamic symbol table generation, as well as the setting of the
EI_ABIVERSION field in the ELF file header.  In particular ensure that
symbol versioning works and that `__gnu_absolute_zero' gets assigned a
version (any will do) even if it has not been listed for exportation in
a linker version script.

47275900ad PR ld/21375: MIPS: Fix non-zero run-time value for undefined weaks
We have an issue in the MIPS backend, with the handling of undefined
hidden and internal weak symbols.  References to such symbols are
supposed to resolve to 0 according to the ELF gABI[1]:

"Unresolved weak symbols have a zero value."

and the 64-bit MIPS psABI[2]:

"If a symbol with one of these [hidden or internal] attributes has no
definition within the executable/DSO being linked, then it must be
resolved to allocated space if common, resolved to zero if weak, or an
error reported otherwise."

however if a GOT relocation is used, then a local GOT entry is created
and used to satisfy the reference.  Such an entry is then (in DSO and
PIE binaries) subject to the usual load-time relocation, which means a
non-zero value will be returned if the base address is non-zero.  This
will defeat the usual run-time sequence like:

void a (void) __attribute__ ((visibility ("hidden"), weak));

void
x (void)
{
  if (a)
    a ();
}

This can be reproduced with this simple code:

$ cat libtest.c
extern int a __attribute__ ((visibility ("hidden"), weak));

int *
x (void)
{
  return &a;
}
$ cat test.c

int *x (void);

int
main (void)
{
  printf ("a: %p\n", x ());

  return 0;
}
$ gcc -shared -fPIC -o libtest.so libtest.c
$ gcc -o test test.c -Wl,-rpath,$(pwd) libtest.so
$ ./test
a: 0x77184000
$

The usual approach targets take is making all the steps required to
assign a GOT entry for the symbol referred, and then leave its contents
at zero with no dynamic relocation attached, therefore ensuring that the
value does not change at load time.  However this is not going to work
with the implicitly relocated GOT the MIPS psABI specifies[3]:

"The dynamic linker relocates the global offset table by first adding
the difference between the base where the shared object is loaded and
the value of the dynamic tag DT_MIPS_BASE_ADDRESS to all local global
offset table entries."

and we cannot therefore use the local GOT part.

And we cannot offhand use the global part either, as the symbol would
then have to be exported and possibly wrongly preempt symbols in other
modules involved in the dynamic load, because as per the ELF gABI[1] we
are not allowed to enter a hidden or internal symbol into the dynamic
symbol table (and then use its associated GOT entry):

"A hidden symbol contained in a relocatable object must be either
removed or converted to STB_LOCAL binding by the link-editor when the
relocatable object is included in an executable file or shared object."

and:

"An internal symbol contained in a relocatable object must be either
removed or converted to STB_LOCAL binding by the link-editor when the
relocatable object is included in an executable file or shared object."

So we have to choose something else.

Our choice is further limited by the need for the reference associated
with the GOT relocation to stay within the signed 16-bit limit from the
GOT pointer base register, while being compliant with the ELF gABI and
the MIPS psABI.  However as Alan Modra has observed[4] one possibility
is to edit (relax) the code such that the GOT reference is removed
altogether.

Based on these observations then modify MIPS BFD linker backend code to:

1. Interpret code associated with GOT relocations and relax the usual LW
   or LD instructions into a corresponding immediate load operation that
   places the value of 0 in the intended register, while leaving the GOT
   entry allocated and initialized as usually.

2. Leave any other instructions associated with GOT relocations in place
   and instead redirect the reference to a global GOT entry associated
   with a special `__gnu_absolute_zero' symbol created for this purpose,
   whose value is 0, SHN_ABS section marks it absolute, binding is
   global and export class protected, ensuring that the locally provided
   value is always used at load time, and that the value is not
   relocated by the dynamic loader.

3. Adjust any high-part GOT relocation used, typically associated with
   a LUI instruction, accordingly, so that run-time consistency is
   maintained, either by resolving to the original entry if the
   instruction associated with the corresponding low-part GOT relocation
   has been relaxed to an immediate load (in which case the value loaded
   with LUI will be overwritten), or by also redirecting the reference
   to `__gnu_absolute_zero' to complete the GOT access sequence if that
   symbol has been used.

4. Add a target `elf_backend_hide_symbol' hook, for the three MIPS ABIs,
   which prevents the `__gnu_absolute_zero' symbol from being forced
   local, to ensure that the redirection works and the symbol remains
   global/protected with existing linker scripts unchanged.

5. Observing the issue with handling SHN_ABS symbols in the GNU dynamic
   loader, covered by glibc PR 19818, set the EI_ABIVERSION field in the
   ELF file header produced to 4 (ABI_ABSOLUTE) if `__gnu_absolute_zero'
   symbol has been produced and the target configured indicates the GNU
   operating system, so that broken versions of the GNU dynamic loader
   gracefully reject the file in loading rather than going astray.  Keep
   EI_ABIVERSION at the original value for other operating systems or if
   no `__gnu_absolute_zero' symbol has been made.

The name of the special `__gnu_absolute_zero' has no meaning other than
how a human reader can interpret it, as it is ignored in dynamic loading
in the handling of the scenarios concerned.  This is because the symbol
resolves locally, and it's only the symbol's attributes that matter so
that the associated GOT entry remains unchanged at load time.

Therefore the name is somewhat arbitrary, observing however the need to
use the name space reserved for the system so that it does not conflict
with a possible user symbol, and hence the leading underscore, and also
the `gnu' infix to denote a GNU feature.  Other implementations wishing
to address the problem in a similar way may choose a different name and
have the solution still work, possibly with a mixture of modules used in
a dynamic having symbols of different names provided, which will however
not interact with each other due to the protected export class.

The symbol can be referred explicitly, however the name is an internal
implementation detail rather than a part of the ABI, and therefore no
specific semantics is guaranteed.

One limitation of this change is that if `__gnu_absolute_zero' has been
already defined, then we do not wipe the old definition and all kinds of
odd behavior can result.  This is however like with other symbols we
internally define, such as `_GLOBAL_OFFSET_TABLE_' or `__rld_map', and
therefore left as a possible future enhancement.

As an optimization the relaxation of LW and LD instructions to a load of
immediate zero is always made, even SVR4 PIC code for code that will end
up in a regular (non-PIE) executable, because there is a cache advantage
with the avoidance of a load from the GOT, even if it is otherwise
guaranteed to remain zero.  It does not reliably happen though, due to a
symbol exportation issue affecting executables, covered by PR ld/21805.

One existing test case needs to be updated, as it triggers relaxation
introduced with this change and consequently linker output does not
match expectations anymore.  As we want to keep the original issue
covered with the test case modify it then to use the LWL instruction in
place of LW, and adjust the output expected accordingly.

90c745dc54 x86: Don't mask out the GNU_PROPERTY_X86_UINT32_VALID bit
Since only the GNU_PROPERTY_X86_UINT32_VALID bit may be set in data-only
relocatable objects which don't contain any instructions, linker
shouldn't mask out the GNU_PROPERTY_X86_UINT32_VALID bit when merging
GNU_PROPERTY_X86_XXX bits.  Otherwise, linker output doesn't contain
GNU_PROPERTY_X86_XXX property with any data-only relocatable inputs.
This patch keeps the GNU_PROPERTY_X86_UINT32_VALID bit and updates
readelf to print "<None>" if GNU_PROPERTY_X86_XXX property only has
the GNU_PROPERTY_X86_UINT32_VALID bit.

3d9c8f6b3f Delay evaluation of alignment expressions in output sections
git commit 702d16713 broke expressions using CONSTANT(COMMONPAGESIZE)
in ALIGN or SUBALIGN of output section statements, because these
optional fields were evaluated at script parse time and the patch in
question delayed setting of config.commonpagesize.  The right thing to
do is keep the tree representation of those fields for later
evaluation.

a9eafb08b3 x86: Update GNU_PROPERTY_X86_XXX macros
This patch updates GNU_PROPERTY_X86_XXX macros:

1. GNU_PROPERTY_X86_UINT32_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in all relocatable inputs:

 #define GNU_PROPERTY_X86_UINT32_AND_LO      0xc0000002
 #define GNU_PROPERTY_X86_UINT32_AND_HI      0xc0007fff

2. GNU_PROPERTY_X86_UINT32_OR_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs:

 #define GNU_PROPERTY_X86_UINT32_OR_LO    0xc0008000
 #define GNU_PROPERTY_X86_UINT32_OR_HI    0xc000ffff

3. GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs and the property is
present in all relocatable inputs:

 #define GNU_PROPERTY_X86_UINT32_OR_AND_LO   0xc0010000
 #define GNU_PROPERTY_X86_UINT32_OR_AND_HI   0xc0017fff

4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED
and GNU_PROPERTY_X86_FEATURE_2_XXX bits.

GNU_PROPERTY_X86_FEATURE_1_AND is unchanged.  GNU_PROPERTY_X86_ISA_1_USED
and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted
processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful.
A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined.  The previous
GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to
GNU_PROPERTY_X86_COMPAT_ISA_1_XXX.

When glibc is enabled with the new GNU_PROPERTY_X86_XXX bits:

https://groups.google.com/forum/#!topic/x86-64-abi/-D05GQ3kWrA

f7309df20c x86: Properly merge GNU_PROPERTY_X86_ISA_1_USED
Without the GNU_PROPERTY_X86_ISA_1_USED property, all ISAs may be used.
If a bit in the GNU_PROPERTY_X86_ISA_1_USED property is unset, the
corresponding x86 instruction set isn’t used.  When merging properties
from 2 input files and one input file doesn't have the
GNU_PROPERTY_X86_ISA_1_USED property, the output file shouldn't have
it neither.  This patch removes the GNU_PROPERTY_X86_ISA_1_USED
property if an input file doesn't have it.

This patch replaces the GNU_PROPERTY_X86_ISA_1_USED property with the
GNU_PROPERTY_X86_ISA_1_NEEDED property which is the minimum ISA
requirement.

df136d64fa PowerPC64 EH info for _notoc linkage stubs
This patch generates EH info for the new _notoc linkage stubs, to
support unwinding from asynchronous signal handlers.  Unwinding
through the __tls_get_addr_opt stub was already supported, but that
was just a single stub.  With multiple stubs the EH opcodes need to be
emitted and sized when iterating over stubs, so this is done when
emitting and sizing the stub code.  Emitting the CIEs and FDEs is done
when sizing the stubs, as we did before in order to have the linker
generated FDEs indexed in .eh_frame_hdr.  I moved the final tweaks to
FDEs from ppc64_elf_finish_dynamic_sections to ppc64_elf_build_stubs
simply because it's tidier to be done with them at that point.

05d0e962f0 R_PPC64_REL24_NOTOC support
R_PPC64_REL24_NOTOC is used on calls like "bl foo@notoc" to tell the
linker that linkage stubs for PLT calls or long branches can't use r2
for pic addressing.  Instead, new stubs that generate pc-relative
addresses are used.  One complication is that pc-relative offsets to
the PLT may need to be 64-bit in large programs, in contrast to the
toc-relative addressing used by older PLT linkage stubs where a 32-bit
offset is sufficient until the PLT itself exceeds 2G in size.

.eh_frame info to cover the _notoc stubs is yet to be implemented.

3f6ff4799b Lose _r2off in powerpc64 stub names
Not a lot is conveyed by putting _r2off in a stub symbol that can't be
seen by inspecting the stub code or the toc restoring instruction
immediately after a call via such a stub.  Also, we don't distinguish
plt_call stub symbols from plt_call_r2save stub symbols, so this patch
makes long branch and plt branch stub symbols consistent with that
decision.

a67ae9b01a Re: PowerPC64 __tls_get_addr_opt stub .eh_frame fix
The modified test failed on some powerpc targets due to differences in
default hash style.  If the default hash style is both, then more
sections are created, bumping section ids.  Section id is used in stub
symbols and although the test is careful to not depend on id in
labels, the stub hash traversal order changes when stub names change.
That lead to the stubs being emitted in a different order and thus not
matching expected output.

b8891f8d62 Add support for the C_SKY series of processors.
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants.  V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc.  There is support for bare-metal ELF targets and Linux with both glibc and uClibc.

This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics.  C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers.  (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about.

491993044b Enhance powerpc ld -r --relax
One of the ill effects of ld -r is to mash together sections.  That
can result in reduced icache performance at runtime due to unexpected
movement of code.  Another problem is that sections can become too
large to link on targets that have limited relative addressing.  ld -r

inserting trampolines, but the powerpc support added lots of

241e64e3b4 x86: Add a GNU_PROPERTY_X86_ISA_1_USED note if needed
When -z separate-code, which is enabled by default for Linux/x86, is
used to create executable, ld won't place any data in the code-only
PT_LOAD segment.  If there are no data sections placed before the
code-only PT_LOAD segment, the program headers won't be mapped into
any PT_LOAD segment.  When the executable tries to access it (based
on the program header address passed in AT_PHDR), it will lead to
segfault.  This patch inserts a GNU_PROPERTY_X86_ISA_1_USED note if
there may be no data sections before the text section so that the
first PT_LOAD segment won't be code-only and will contain the program
header.

Testcases are adjusted to either pass "-z noseparate-code" to ld or
discard the .note.gnu.property section.  A Linux/x86 run-time test is
added.

The aarch64 ifunc error message test was changed to no longer expect

also disables the executable tests added by H.J. Lu for aarch64, just as

In that case the output section is the absolute section, which has no
ELF section data attached, so trying to set its `sh_size' parameter
causes a null pointer dereference.

This is only done as the value for the DT_RELSZ dynamic entry is being
set, so fix the problem by not creating DT_REL, DT_RELSZ or DT_RELENT
dynamic entries in the first place if the dynamic relocation section
will not be output, as with no dynamic relocation data present these
would not serve their purpose anyway.

Add a generic ELF test case to verify that no dynamic relocation data is
reported in the dynamic segment.

afca762f59 S/390: Improve partial relro support for 64 bit
Currently on S/390 the .got.plt always comes first which prevents the
GNU_RELRO segment from being extended across the non-plt GOT entries.

Just swapping both unfortunately is not that simple since our ABI
requires the _GLOBAL_OFFSET_TABLE_ symbol to point to the very
beginning of the entire GOT. Of the 3 magic GOT entries the first is
accessed via got pointer while second and third are being accessed via
DT_PLTGOT.  In order to keep them together we make DT_PLTGOT to point
to the .got instead of .got.plt.  However, this violates an assumption
in the dynamic linker prelink undo code about the GOTPLT entries
starting at DT_PLTGOT + 3.  We got rid of this requirement with a
Glibc patch already in version 2.24:
https://sourceware.org/ml/libc-alpha/2016-06/msg01302.html

So the S/390 relro GOT layout will look like this with this patch:

      +----------------------------------+
      |got[0]: DYNAMIC                   |   <--- _GLOBAL_OFFSET_TABLE_ == DT_PLTGOT .got
      |got[1]: link_map parm             |
      |got[2]: &_dl_runtime_resolve      |
      +----------------------------------+
      |                                  |   non-plt GOT entries
      |                                  |
      |                                  |
      +----------------------------------+
      |                                  |   <--- .gotplt, PLT GOT entries
      |                                  |
      |                                  |
      |                                  |
      +----------------------------------+

The patch detects the current layout in size_dynamic_section in order
to deal also with linker scripts not generated by this ld version.
With partial relro enabled we pick a linker script where .got and
.got.plt are swapped which then triggers the rest of the logic.

78da84f994 MIPS/LD/testsuite: Correct mips-elf.exp test ABI/emul/endian arrangement
Similarly to commit 86b24e15c4 ("MIPS/LD/testsuite: Correct
comm-data.exp test ABI/emul/endian arrangement") update the mips-elf.exp
test script to:

- correctly select emulations for targets using non-traditional MIPS
  emulations,

- correctly select ABIs for targets that do not support all of them,

- use the default endianness selection where possible to benefit targets
  that support only one,

- simplify test invocation by providing ABI-specific `run_dump_test'
  wrappers, specifically `run_dump_test_o32', `run_dump_test_n32',
  `run_dump_test_n64' and `run_dump_test_eabi', which remove the need to
  use conditionals across the Expect script or to repeat ABI-specific
  GAS and LD flags with each invocation,

removing numerous test failures for `mips-sgi-irix6', `mips64-openbsd',
`mips64el-openbsd' and `mips64el-ps2-elf' targets and broadening
coverage for several MIPS targets.

There are some new failures for the `mips64el-ps2-elf' target with tests
that were not previously run for that target:

FAIL: MIPS16 link branch to absolute expression (n32)
FAIL: MIPS16 link branch to absolute expression 1 (n32)
FAIL: MIPS16 link branch to absolute expression 2 (n32)
FAIL: microMIPS link branch to absolute expression (n32)
FAIL: MIPS ELF got reloc n32
FAIL: MIPS ELF xgot reloc n32
FAIL: undefined weak symbol overflow (n32)
FAIL: R_MIPS16_HI16 and R_MIPS16_LO16 relocs n32
FAIL: ld-mips-elf/attr-gnu-4-0-n32-ph
FAIL: ld-mips-elf/attr-gnu-4-1-n32-ph
FAIL: ld-mips-elf/attr-gnu-4-2-n32-ph
FAIL: ld-mips-elf/attr-gnu-4-3-n32-ph
FAIL: MIPSr6 JALR reloc unaligned/cross-mode link test (n32)

which are mostly due to dump discrepancies caused by mapping differences
coming from the default linker scripts used by these test cases, or
sometimes because of the specific MIPS processor architecture recorded
in the ELF file taking precedence over the general MIPS ISA level also
recorded.  Finally, the R_MIPS16_HI16/R_MIPS16_LO16 relocation test
failure is a preexisting issue with the IRIX style emulation.

These failures will have to be addressed separately.

1cb83cac9a MIPS/BFD: Fix TLS relocation resolution for regular executables
Correct an issue with commit 0f20cc3522 ("TLS support for MIPS"),
<https://sourceware.org/ml/binutils/2005-02/msg00607.html>, where a
condition used to determine whether to use a dynamic symbol for GD, LD
and IE TLS dynamic relocations against a symbol that has been defined
locally has been incorrectly reversed.

It's executables rather than dynamic shared objects where no symbol is
required, because such symbols cannot be preempted and therefore their
values (thread pointer offsets) are fixed at the static link time as is
the associated module ID of the main executable, so the original
condition should have been `shared' instead of `!shared'.  This wrong
condition was then later converted from `!shared' to `!bfd_link_pic',
with commit 0e1862bb40 ("Add output_type to bfd_link_info").

Use the correct `bfd_link_dll' condition then, and adjust code for the
dynamic symbol index possibly being -1 as with symbols that have been
forced local, removing unnecessary dynamic relocations from dynamic
regular executables.  PIE executables are unaffected as the existing
condition excluded them by chance due to the conversion mentioned above.

9143e72c6d PR ld/22570: MIPS/BFD: Fix TLS relocation resolution for PIE executables
Correct a commit 0e1862bb40 ("Add output_type to bfd_link_info") issue
and use `bfd_link_dll' rather than `bfd_link_pic' in determining whether
to fully resolve GD, LD and IE TLS relocations referring to symbols
locally defined rather than deferring them to the load time by means of
dynamic relocations.

Such symbols cannot be preempted in PIE executables, which are
necessarily PIC, and therefore their values (thread pointer offsets) are
fixed at the static link time as is the associated module ID of the main
executable.

Given the `tlsbin-o32.s' and `tlsdyn-o32.s' sources from our test suite
this removes the absolute TLS relocations from the static:

git commit 624940689a wrongly changed fill.d and fill16.d notarget

624940689a ld testsuite use of notarget
Much of the time it is better to use xfail rather than notarget to
hide a testsuite failure no one is planning on fixing.

1) When a target is fixed, an inappropriate xfail results in XPASS
   whereas notarget is silent.  Leaving in an inappropriate notarget
   entry risks the bug reappearing later, silently.
2) Tests might be used as a template for a new test, carrying over
   notarget and/or xfail.  Inappropriate notarget entries are silent.
3) An xfailed test that mysteriously XPASSes might actually indicate a
   bug.

The current default dumps for n64 GOT relocation tests only work for
IRIX targets really, while the Linux dumps are suitable for non-Linux
targets as well.  Make the Linux dumps the default then and handle the

Define an `irix' variable as a shorthand for `[istarget *-*-irix*]' and

relocation tests.

4b8377e7db MIPS/BFD: Do not redirect to discarded lazy binding stubs
Correct a MIPS/BFD linker issue with dynamic symbol and corresponding
GOT entry values being redirected to lazy binding stubs where the stubs
section has been discarded by assigning to the `/DISCARD/' output
section in the linker script used.  The issue manifests itself by the
values entered being relative to the absolute section, which is what any
discarded sections are internally assigned in the linker.

For the `stub-dynsym-2.s' piece of code included as a test case with
this change this issue results in the dynamic symbol table and the GOT
looking like:

Symbol table '.dynsym' contains 3 entries:
   Num:    Value  Size Type    Bind   Vis      Ndx Name
     0: 00000000     0 NOTYPE  LOCAL  DEFAULT  UND
     1: 00000010     0 FUNC    GLOBAL DEFAULT  UND bar
     2: 00000000     0 FUNC    GLOBAL DEFAULT  UND foo

Primary GOT:
 Canonical gp value: 00097ff0

 Reserved entries:
   Address     Access  Initial Purpose
  00090000 -32752(gp) 00000000 Lazy resolver
  00090004 -32748(gp) 80000000 Module pointer (GNU extension)

 Global entries:
   Address     Access  Initial Sym.Val. Type    Ndx Name
  00090008 -32744(gp) 00000010 00000010 FUNC    UND bar
  0009000c -32740(gp) 00000000 00000000 FUNC    UND foo

if assembled to regular MIPS code, or:

Symbol table '.dynsym' contains 3 entries:
   Num:    Value  Size Type    Bind   Vis      Ndx Name

     2: 00000001     0 FUNC    GLOBAL DEFAULT  UND foo

  0009000c -32740(gp) 00000001 00000001 FUNC    UND foo

if assembled to microMIPS code.  Symbol values and GOT entries record
the offset into the inexistent stubs section and the ISA bit rather than
zero, which would be the case if a lazy binding stub was not used for
other reasons, such as the value of the symbol being taken for a purpose
other than making a function call (e.g. an R_MIPS_GOT16 relocation).

Correct the issue by refraining from redirecting symbols to lazy binding
stubs if the stubs section is going to be discarded.

8a8c916960 LD/testsuite: run_dump_test: Report UNSUPPORTED for excluded targets
Bring the LD implementation of `run_dump_test' in line with its binutils
and GAS counterparts and report the UNSUPPORTED status for tests the run
of which has been prevented by means of one or more of `target',
`alltargets' and `notarget' tags.  Define `skip', `anyskip' and `noskip'
tags, which do not report anything for tests that are not run.

The rationale behind this is that we want to have unsupported tests
reported to ensure that they have actually been attempted and have not
been accidentally suppressed.  Then tests which have target-specific
variants that cannot be expressed with a single .d file can make use of
the newly added tags to silently suppress the uninteresting variants.

c0c468d562 [ARM] Update bfd's Tag_CPU_arch knowledge
BFD's bfd_get_mach () function returns a bfd specific value representing
the architecture of the target which is populated from the Tag_CPU_arch
build attribute value of that target. Among other users of that
interfacem, objdump which uses it to print the architecture version of
the binary being examinated and to decide what instruction is available
if run with "-m arm" via its own mapping from bfd_mach_arm_X values to
feature bits available.

However, both BFD and objdump's most recent known architecture is
Armv5TE. When encountering a newer architecture bfd_get_mach will return
bfd_mach_arm_unknown. This is unfortunate since objdump uses that value
to allow all instructions on all architectures which is already what it
does by default, making the "-m arm" trick useless.

This patch updates BFD and objdump's knowledge of Arm architecture
versions up to the latest Armv8-M Baseline and Mainline, Armv8-R and
Armv8.4-A architectures. Since several architecture versions (eg. 8.X-A)
share the same Tag_CPU_arch build attribute value and
bfd_mach_arm values, the mapping from bfd machine value to feature bits
need to return the most featureful feature bits that would yield the
given bfd machine value otherwise some instruction would not disassemble
under "-m arm" mode. The patch rework that mapping to make this clearer
and simplify writing the mapping rules. In particular, for simplicity
all FPU instructions are allowed in all cases.

Finally, the patch also rewrite the cpu_arch_ver table in GAS to use the
TAG_CPU_ARCH_X macros rather than hardcode their value.

789ff5b6c2 PR ld/22966: Fix n64 MIPS `.got.plt' range checks
The addressable signed 32-bit range for n64 MIPS `.got.plt' references
is from 0xffffffff7fff8000 to 0x7fff7fff, due to how the composition of
an LUI and an LD instruction works for address calculation in the 64-bit
addressing mode, such as when CP0.Status.UX=1.

We currently have a range check in `mips_finish_exec_plt', however it is
not correct as it verifies that the `.got.plt' start address referred is
between 0xffffffff80000000 and 0x7fffffff.  It is also implemented as an
assertion rather than a proper error message despite that the situation
can be triggered by user input.  Additionally there is no check made for
individual `.got.plt' entries referred even though they can be out of
range while the `.got.plt' start address is not.

Fix all these problems and use the correct range for the check, limiting
it to n64 output files, and then issue a proper error message both in
`mips_finish_exec_plt' and in `_bfd_mips_elf_finish_dynamic_symbol',
suggesting the use of the `-Ttext-segment=...' option that will often
work and with the default linker scripts in particular.  Add suitable
tests covering boundary cases.

a4eb69274d MIPS/LD/testsuite: XFAIL DT_TEXTREL map file warning test
Remove:

FAIL: DT_TEXTREL map file warning

introduced with commit 63c1f59d66 ("readonly_dynrelocs"), coming from
the lack of a "dynamic relocation against `foo' in read-only section
`.rodata'" warning message produced.

The cause of the failure is that for sections which have dynamic
relocations attached the MIPS backend sets SHF_WRITE, in
`mips_elf_create_dynamic_relocation', yielding:

$ readelf -S textrel.so | grep rodata
  [ 8] .rodata           PROGBITS        00000254 000254 000004 00  WA  0   0  1
$

so the section is read/write and therefore there is nothing to warn
about.

This arrangement came from commit 7403cb6305 ("PATCH for N32 ABI"),
<https://sourceware.org/ml/binutils/1999-q2/msg00375.html>, i.e. for all
practical purposes it has been there since forever, and therefore it can
be considered a part of the ABI and the test case irrelevant for MIPS
targets.

We don't have a clean way to request UNSUPPORTED result, which would be
the most appropriate here, so just XFAIL the test instead.

7f923b7fd2 ELF dynsyms
Many ELF targets arrange to emit a number of section symbols in
.dynsym for use by dynamic relocations.  This happens before the
dynamic relocations are output, and the need for those symbols
determined.  In most cases they are not needed.  A proper analysis of
the need for dynamic section symbols is target specific and tedious,
so this patch just excludes them in the obvious case when no
dynamic relocations are present.

The patch also runs the new pr23161 and pr23162 tests on more targets.

fd161d860f Define various symbols conditionally in shared libraries
The values of symbols in shared libraries like _end, _edata, and
__bss_start are generally not that useful outside of the shared
library.  This patch defines them conditionally with PROVIDE, since a
shared library might need the local value.  An example is glibc ld.so
local access to "_begin", "_etext" and "_end".  (ld.so gains access to
the local values by making the references using hidden visibility.
That makes the definitions hidden too.)

We can't use PROVIDE_HIDDEN in the linker scripts because the shared
library might need the value of the symbol in the executable.  An
example is freebsd libc dynamic access to "_end".

099bb8fb97 ld: Add _bfd_elf_link_hide_sym_by_version
bfd_hide_sym_by_version can't be used to check if a versioned symbol is
hidden.  This patch adds _bfd_elf_link_hide_sym_by_version to support
both versioned and unversioned symbols by extracting versioned symbol
check from _bfd_elf_link_assign_sym_version.

9933dc5273 PR20659, Objcopy and change section lma failing
Sections may well belong in multiple segments.  The testcase in the PR
saw an allocated section being assigned to an ABIFLAGS segment, then
not being assigned to a LOAD segment because it had already been
handled.  To fix that particular problem this patch sets and tests
segment_mark only for LOAD segments.  I kept the segment_mark test for
LOAD segments because I think there may otherwise be a problem with
zero size sections.

A few other problems showed up with the testcase.  Some targets align
.dynamic, resulting in the test failing with "section .dynamic lma
0x800000c0 adjusted to 0x800000cc" and similar messages.  I've tried
to handle that with some more hacks to the segment lma, which do the
right thing for the testcase, but may well fail in other situations.

I've also removed the tests of segment lma (p_paddr) and code involved
in deciding that an adjusted segment no longer covers the file or
program headers.  Those test can't be correct in the face of objcopy
--change-section-lma.  It may be necessary to reinstate the tests but
do them modulo page size, but we'll see how this goes.

	Don't clear includes_phdrs or includes_filehdr based on p_paddr

493ffac5aa Fix binary compatibility between GCC and the TI compiler for the PRU target.
My original implementation for LDI32 pseudo does not conform to
the TI ABI.  I wrongly documented my TI PRU ELF object files inspection,
which got propagated into my binutils implementation.

Issue was exposed when running the GCC ABI testsuite against TI toolchain.
According to TI ABI, LDI32 must use first LDI instruction to load
the MSB 16bits, and second LDI instruction for the LSB 16bits.

This patch will break binary compatibility with previously released
binutils versions for PRU. Still, I think it is better to fix
binutils to conform to the chip vendor ABI.

3be08ea472 BFD: Prevent writing the MIPS _gp_disp symbol into symbol tables
The _gp_disp is a magic symbol, always implicitly defined by the linker.
It does not make a sense to write it into symbol tables for output files.
Moreover, now if the linker gets a version script, the _gp_disp symbol
gets zero version definition index.  The zero index means[1]:

"The symbol is local, not available outside the object."

But the _gp_disp symbol has GLOBAL binding.  That confuses some tools
like for example the LLD linker when they get such files as inputs.

This patch fixes the problem - it prevents writing the _gp_disp symbol
in regular and dynamic symbol tables.

This was tested by running LD test suite on a mipsel-linux board.

6d9dabbbc6 testsuite: Support filtering targets by TCL procedure in `run_dump_test'
Implement a more complex way of selecting targets to include or exclude
with `run_dump_test' cases, by extending the syntax for the `target',
`not-target', `skip' and `not-skip' options (with the binutils and GAS
test suites) and the `target', `alltargets' and `notarget' options (with
the LD test suite) to also accept a name of a TCL procedure instead of a
target triplet glob matching expression.  The result, 1 or 0, of the
procedure determines whether the test is to be run or not.  This mimics
and expands `dg-require-effective-target' from the GCC test suite.

Names of TCL procedures are supplied in square brackets `[]' as with TCL
procedure calls, observing that target triplet glob matching expressions
do not normally start and end with matching square brackets both at a
time.  Arguments for procedures are allowed if required.

Having a way to specify a complex condition for a `run_dump_test' case
to run has the advantage of keeping it local within the test case itself
where tool options related to the check might be also present, removing
the need to wrap `run_dump_test' calls into an `if' block whose only
reason is to do a feature check, and ultimately lets one have the test
reported as UNSUPPORTED automagically if required (not currently
supported by the `run_dump_test' options used for LD).

2ac93be706 Remove arm-aout and arm-coff support
This also removes arm-netbsd (not arm-netbsdelf!), arm-openbsd, and
arm-riscix.  Those targets weren't on the obsolete list but they are
all aout, and it doesn't make all that much sense to remove arm-aout
without removing them too.

5a8edf8ece Test that gcc -B picks up new ld
gcc configured using --with-ld always uses that particular version of
ld if it exists.  This patch adds a check that the ld version reported
directly from ld-new matches that reported via gcc.  I chose to
compare the ld --version output rather than a more strict test (for
example by gcc --print-prog-name=ld), because the version test allows
a user to run the ld testsuite after installing a new ld (in the place
expected by gcc).

Sample output:

Running target unix

702d167134 powerpc common-page-size
max-page-size only matters for demand paged executables or shared
libraries, and the ideal size is the largest value used by your
operating system.  Values larger than necessary just waste file space
and memory.  common-page-size also affects file and memory size,
trading a possible small increase in file size for a decrease in
memory size when the operating system is using a common-page-size
page.  With a powerpc max-page-size of 64k and common-page-size of 4k
many executables will use no more memory pages when the system page
size is 4k than an executable linked with -z max-page-size=0x1000,
yet will still run on a system using 64k pages.  However, when running
on a system using 64k pages relro protection will not be completely
effective.

Due to the relro problem, powerpc binutils has been using a default
common-page-size of 64k since 2014-12-18 (git commit 04c6a44c7),
leading to complaints about increased file and memory sizes.  People
not using relro do have a valid reason to complain..

So this patch introduces an extra back-end value to use as the default
for common-page-size when generating relro executables, and enables
the support for powerpc.  Non relro executables will now be generated
with a default common-page-size of 4k.

2d7ad24e87 Support PLT16 relocs against local symbols
Necessary if gcc is to use PLT16 relocs to implement -mlongcall, and
there isn't a good technical reason why local symbols should be
excluded from PLT16 support.  Non-ifunc local symbol PLT entries go in
a separate section to other PLT entries.  In a fixed position
executable they won't need to be relocated, and in a PIE or shared
library I chose to not implement lazy relocation.

f8745e1cd1 PR ld/22972 on SPARC.
This is a regression for the corner case of a hidden symbol in a PIC/PIE
binary which is subject to both a new-style GOTDATA relocation and an
old-style GOT relocation.  In this case, depending  on the link order,
the R_SPARC_RELATIVE dynamic relocation for the GOT slot needed because
of the old-style relocation can be replaced with R_SPARC_NONE coming
from the GOTDATA relocation.

The fix simply records whether an old-style GOT relocation is seen for a
symbol and prevents the R_SPARC_NONE from being generated in this case.

bf54968b12 x86-64: Add ENDBR64 to the TLSDESC PLT entry
The TLSDESC entry in a lazy procedure linkage table is called indirectly
with "callq *(%rax)".  This patch adds an ENDBR64 to support indirect
branch tracking in Intel CET.  The TLSDESC PLT entry now looks like:

0xf3, 0x0f, 0x1e, 0xfa,  /* endbr64             */
0xff, 0x35, 8, 0, 0, 0,  /* pushq GOT+8(%rip)   */
0xff, 0x25, 16, 0, 0, 0  /* jmpq *GOT+TDG(%rip)  */

The BND prefix isn't needed since MPX isn't used for TLSDESC.

ed38187755 gc.exp: Remove extraneous LD flags from the personality test
Complement commit 8988502d75 ("MIPS/LD/testsuite: Correct dynamic
links with VR4100, VR4300 and VR5000") and commit bf48520113 ("gc.exp:
Fix a typo: $LFLAGS -> $LDFLAGS"), and remove extraneous additional LD
flags explicitly passed to the personality test on invocation.  This
passing has accidentally leaked from a WIP version of the former change.

With the actual version committed the $LDFLAGS global variable is used
instead for `run_dump_test' to use implicitly, so that `-call_shared'
precedes `-lpersonality' on the linker's command line, as otherwise a
shared `libpersonality.so' library wouldn't be considered for linking,
causing the test to fail.

f657f8c4a1 Fix Sparc, s390 and AArch64 targets so that they can handle relocs against ifunc symbols found in note sections.
Following on from PR 22929, I have found the same problem exists with
  other ifunc supporting targets too.  Plus see this link for the bug
  being reported against the s390x binutils for Fedora rawhide:

     https://bugzilla.redhat.com/show_bug.cgi?id=1553705

  So I am going to check in the patch below which applies the same
  change that H.J. made for the x86_64 target to the other affected
  targets.  (Specifically: S390, AArch64 and Sparc).  Plus it adds a new
  test to the linker testsuite to make sure that this problem stays
  fixed.

dfb93f1158 PR ld/21900: MIPS: Fix relocation processing with undefined symbols
Currently, when `mips_elf_calculate_relocation' is asked to relocate an
undefined symbol, it reports an error or a warning and immediately
returns without performing the relocation.  This is fine if the link
fails, but if unresolved_syms_in_objects == RM_GENERATE_WARNING, the
link will continue and output some unrelocated code, which is a
regression from commit e7e2196da3 ("MIPS/BFD: Correctly report
undefined relocations").

Fix this by continuing after calling the `undefined_symbol' hook unless
this is an error condition.

df5f2391f7 ld error/warning messages
This patch standardizes messages in ld, to better conform to the GNU
coding standard.  Besides issues of capitalization and full-stops,
I've
- Split up help messages for target options, so that adding a new
  option does not mean loss of translation for all the others.
- Embedded tabs have been removed, since a user might have tab stops
  set at other than 8 char intervals.
- Added missing program name (%P).  ld isn't the compiler.
- Put %F and %X first (and removed %X if %F was present).  These can
  go anywhere, but look silly in the m%Fiddle of a message, and
  choosing "%P%F:" in some messages but "%F%P:" in others leads to the
  likelihood of duplication in ld.pot.  Besides, the colon belongs
  with %P.

90b6238f06 ARM and AArch64 messages
More standarization of error/warning messages.  The ARM backend has
some multi-line error messages, which don't fit particularly well with
the GNU coding standard insistence that error messages shouldn't be
capitalized or have a full-stop.  I've replaced the line breaks with
semicolons.

So for instance the following
  system/path/to/ld: myobject.o: invalid special symbol `foo'.
  system/path/to/ld: It must be a global or weak function symbol.
becomes
  system/path/to/ld: myobject.o: invalid special symbol `foo'; it must be a global or weak function symbol

cf97bcb0c3 PPC error/warning messages
The GNU coding standard says error messages should be of the form
  program:sourcefile:lineno: message
or
  program: message

and
"The string message should not begin with a capital letter when it
follows a program name and/or file name, because that isn’t the
beginning of a sentence. (The sentence conceptually starts at the
beginning of the line.) Also, it should not end with a period."

This patch does that for ppc, and removes some British spelling.
I've also switched some error output from using the linker callback
einfo to _bfd_error_handler, due to improved compilation time
argument checking now done for the latter function.

6798f8bfa6 MIPS/BFD: Fix the size of .reginfo' and .MIPS.abiflags' sections
Use the SEC_FIXED_SIZE flag to actually fix the size of `.reginfo' and
`.MIPS.abiflags' sections in `_bfd_mips_elf_always_size_sections', as
originally intended, removing link failures such as:

ld: final link failed: Section has no contents

or:

ld: final link failed: Bad value

or:

ld: foo: .reginfo section size should be 24 bytes, actual size is 32

and assertion failures like:

ld: BFD (GNU Binutils) 2.30.51.20180131 assertion fail .../bfd/elfxx-mips.c:14322

in link scenarios involving a linker script that either creates an
output `.reginfo' or `.MIPS.abiflags' section from scratch or produces
either section from different sections.  If such an output section's
size turns out to be incorrect according to the psABI, then the section
is either truncated or padded out to the correct size, as relevant.

This allows people to handle these sections in a link in an unusual way,
while still addressing the issue covered by commit 58807c48a5
("_bfd_mips_elf_final_link: Notify user about wrong .reginfo size").

The original arrangement, coming from an unindentified change made to
what was called `mips_elf_always_size_sections' back then, between
commit 02650bd0a9 ("This adds ABI flags to MIPS/ELF object files.")
and commit 252b5132c7 ("19990502 sourceware import"), also missing
from BFD ChangeLog files, assumed that the output section size is not
going to change after return from `bfd_elf_size_dynamic_sections', the
caller of that function, called in turn from `ldemul_before_allocation'
via `gld${EMULATION_NAME}_before_allocation' in ld/emultempl/elf32.em,
and ultimately from `lang_process'.  This is because later on in
`lang_process' processing `lang_size_sections' is called , happily
recalculating the section size, and it has actually already been the
case at the time of commit 252b5132c7 ("19990502 sourceware import"),
so the assumption was clearly incorrect right from the beginning.

	* elfxx-mips.c (_bfd_mips_elf_always_size_sections): Set
	SEC_FIXED_SIZE and SEC_HAS_CONTENTS flags for `.reginfo' and
	`.MIPS.abiflags' sections.

the program header isn't included in any LOAD segment.  As the result,

92d9e363b5 ld-elf/eh4: Pass -z max-page-size=0x200000 -z noseparate-code to ld
-z separate-code creates separate code LOAD segment, aligns it to the
maximum page size and places .plt section before .text section.  But
ld-elf/eh4 passes -Ttext 0x400 to linker to place .text section at
address 0x400, which is impossible for linker to accomplish:

$ ld -shared -Ttext 0x400 -z separate-code -o x.so eh4.o

Since PLT in PDE and PC-relative PLT in PIE can be used as function

bd7ab16b45 x86-64: Generate branch with PLT32 relocation
Since there is no need to prepare for PLT branch on x86-64, generate
R_X86_64_PLT32, instead of R_X86_64_PC32, if possible, which can be
used as a marker for 32-bit PC-relative branches.

To compile Linux kernel, this patch:

From: "H.J. Lu" <hjl.tools@gmail.com>
Subject: [PATCH] x86: Treat R_X86_64_PLT32 as R_X86_64_PC32

On i386, there are 2 types of PLTs, PIC and non-PIC.  PIE and shared
objects must use PIC PLT.  To use PIC PLT, you need to load
_GLOBAL_OFFSET_TABLE_ into EBX first.  There is no need for that on
x86-64 since x86-64 uses PC-relative PLT.

On x86-64, for 32-bit PC-relative branches, we can generate PLT32
relocation, instead of PC32 relocation, which can also be used as
a marker for 32-bit PC-relative branches.  Linker can always reduce
PLT32 relocation to PC32 if function is defined locally.   Local
functions should use PC32 relocation.  As far as Linux kernel is
concerned, R_X86_64_PLT32 can be treated the same as R_X86_64_PC32
since Linux kernel doesn't use PLT.

The assumption that R_AARCH64_ABS16 and R_AARCH64_ABS32 relocation in LP64 abi

In this case, it is a value fixed at static linking time.

e54d3c943b LD/testsuite: Pass $AFLAGS_PIC to GAS for PIC assembly
Add $AFLAGS_PIC flags for PIC assembly to a number of tests missing them
and remove `tic6x-*-*' XFAIL annotations from them, previously added to
paper over:

.../ld-new: warning: generating a shared library containing non-PID code

error messages produced due to `-mpic -mpid=near' GAS options having not
been used.  Such errors now do not happen anymore, removing:

XFAIL: Build shared library for pr14170
XFAIL: PR ld/21703 shared
XFAIL: Build shared library for broken linker script test
XFAIL: Build pr17068.so
XFAIL: -Bsymbolic-functions
XFAIL: Build pr20995.so
XFAIL: Build pr22374 shared library

with `tic6x-elf' and `tic6x-uclinux' targets.  These tests now pass all
except for:

FAIL: PR ld/21703 shared

which is now due to a different reason, as follows:

extra regexps in .../ld/testsuite/ld-elf/pr21703-shared.sd starting with "^Symbol table '\.dynsym' contains [0-9]+ entries:$"
EOF from dump.out
FAIL: PR ld/21703 shared

The addition of $AFLAGS_PIC requires the affected test cases to use the
`list' command rather than `{}' characters to create a list, to avoid
the quoting property `{}' also have in TCL.  Consequently the change is
slightly more extensive than it could otherwise be.

Move those ELF shared library tests that are in ld-elf/elf.exp over to

extra flags needed with some targets and shared library builds easier,

af667f2218 MIPS/LD/testsuite: Correct PR ld/22649 test case failures
Fix commit d664fd41e1 ("Ignore dynamic references on forced local
symbols") and use alternative test actions and match patterns to
correctly handle messages like:

.../ld/ld-new: Removing unused section '.reginfo' in file 'tmpdir/pr22649-2b.o'

or:

.../ld/ld-new: Removing unused section '.MIPS.options' in file 'tmpdir/pr22649-2b.o'

produced by LD on MIPS targets, removing:

FAIL: Build pr22649-2c.so
FAIL: Build pr22649-2d.so

test suite failures and tightening checks made with `pr22649-2a.so' and
`pr22649-2b.so' test cases.

Keep the original empty action with `pr22649-2c.so' and `pr22649-2d.so'
links and MIPS/ELF targets though, because for them the linker does not
garbage-collect the `.reginfo' section.  This is because the section has
its flags set differently by code in GAS in `md_begin':

    if (strncmp (TARGET_OS, "elf", 3) != 0)
      flags |= SEC_ALLOC | SEC_LOAD;

and consequently BFD linker code in `_bfd_elf_gc_mark_extra_sections':

	  else if (((isec->flags & SEC_DEBUGGING) != 0
		    || (isec->flags & (SEC_ALLOC | SEC_LOAD | SEC_RELOC)) == 0)
		   && elf_next_in_group (isec) == NULL)
	    isec->gc_mark = 1;

marks these sections to be kept due to their SEC_ALLOC, SEC_LOAD and
SEC_RELOC flags all being zero (`.reginfo' sections never have
relocations attached).

bb363086e7 Fix PR ld/22727 (TLS breakage in PIC/PIE mode on SPARC).
There are actually 2 different bugs:
 1. TLS transition is broken in PIE mode.
 2. TLS is broken in PIC/PIE mode when the __tls_get_addr symbol
    is versioned  (as is the case on Linux and Solaris at least).

The 1st bug is fixed by reverting the problematic change for now
(note that the associated test doesn't pass on SPARC because of another
issue so there is  no formal regression in the testsuite). The 2nd bug
is fixed by changing the  call to _bfd_generic_link_add_one_symbol
on __tls_get_addr into a mere lookup in _bfd_sparc_elf_check_relocs.

9e390558ce PowerPC PLT stub tidy
This is in preparation for the next patch adding Spectre variant 2
mitigation for PowerPC and PowerPC64.  Besides tidying code involved
in stub output (to reduce the number of places where bctr is output),
the patch adds some user visible features:

1) PowerPC64 ELFv2 global entry stubs now are aligned under the
   control of --plt-align, with a default alignment of 32 bytes.
2) PowerPC64 __glink_PLTresolve is no longer padded out with nops.
3) PowerPC32 PLT stubs are aligned under the control of --plt-align,
   with the default alignment being 16 bytes as before.
4) The PowerPC32 branch/nop table emitted before __glink_PLTresolve
   is now smaller in many cases.  It was sized incorrectly when the
   __tls_get_addr_opt stub was used, and unnecessarily included space
   for local ifuncs.

bfd/
	* elf32-ppc.c (GLINK_ENTRY_SIZE): Add parameters, handle
	__tls_get_addr_opt, and alignment sizing.
	(TLS_GET_ADDR_GLINK_SIZE): Delete.
	(is_nonpic_glink_stub): Don't use GLINK_ENTRY_SIZE.
	(ppc_elf_get_synthetic_symtab): Recognize stubs spaced at 4, 6,
	or 8 insns.
	(ppc_elf_link_hash_table_create): Init new ppc_elf_params field.
	(allocate_dynrelocs): Use new GLINK_ENTRY_SIZE.
	(ppc_elf_size_dynamic_sections): Likewise.  Size branch table
	by PLT reloc count.
	(write_glink_stub): Handle __tls_get_addr_opt stub.
	Pad out to size given by GLINK_ENTRY_SIZE.
	(ppc_elf_relocate_section): Adjust write_glink_stub call.
	(ppc_elf_finish_dynamic_symbol): Likewise.
	(ppc_elf_finish_dynamic_sections): Write PLTresolve without using
	insn array since so many need rewriting.
	* elf32-ppc.h (struct ppc_elf_params): Add plt_stub_align.
	* elf64-ppc.c (GLINK_PLTRESOLVE_SIZE): Rename from
	GLINK_CALL_STUB_SIZE.  Add htab param and evaluate to size without
	nops.  Adjust all uses.
	(ppc64_elf_get_synthetic_symtab): Don't use GLINK_CALL_STUB_SIZE
	in glink_vma calculation.

	entry stubs.

5ae5d3fd10 pr22374 function pointer initialization
When I added this test I said I'd look at fixing more targets.
That hasn't happened yet, so xfail to tidy results.

	* testsuite/ld-elf/elf.exp: xfail "pr22374 function pointer
	initialization" for currently failing targets.
