With this patch dedicated linker scripts can be generated for partial
relro triggered by defining GENERATE_RELRO_SCRIPT in the target
specific scripts.
This is necessary for e.g. S/390 where usually the .got.plt comes
first and prevents the relro segment from being extended across the
non-plt GOT entries.
The patch started with the work from Marcin taken from the mwk user
branches. However, the patch needed substantial changes due to the
'separate code' feature which got committed in the meantime.

It is usually possible to tell absolute and ordinary symbols apart in
BFD throughout the link, by checking whether the section that owns the
symbol is absolute or not.
That however does not work for ordinary symbols defined in a linker
script outside an output section statement. Initially such symbols are
entered into to the link hash as absolute symbols, owned by the absolute
section. A flag is set in the internal linker expression defining such
symbols to tell the linker to convert them to section-relative ones in
the final phase of the link. That flag is however not accessible to BFD
linker code, including BFD target code in particular.
Add a flag to the link hash then to copy the information held in the
linker expression. Define a macro, `bfd_is_abs_symbol', for BFD code to
use where determining whether a symbol is absolute or ordinary is
required before the final link phase.
This macro will correctly identify the special `__ehdr_start' symbol as
ordinary throughout link, for example, even though early on it will be
assigned to the absolute section. Of course this does not let BFD code
identify what the symbol's ultimate section will be before the final
link phase has converted this symbol (in `update_definedness').

Similarly to commit 86b24e15c45b ("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.

Correct an issue with commit 0f20cc3522e7 ("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 0e1862bb401f ("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.
Adjust test cases accordingly.

Correct a commit 0e1862bb401f ("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

Such symbols cannot be preempted in PIE executables, which are

fixed at the static link time as is the associated module ID of the main

elf32-xgate.c contains many functions that are only stubs and
elf32-xgate.h contains unused declarations. While this might be
reasonable for the initial commit of a port with subsequent work
fleshing out the stubs, xgate has only had two minor target specific
patches since the initial commit over six years ago. The rest of the
changes have been general maintenance work applied to all ELF targets,
and some of this work could have been avoided if the stubs hadn't been
there. So this patch removes all the stubs.
I've kept the functionality of the old elf32_xgate_add_symbol_hook,
implemented in elf32_xgate_backend_symbol_processing. Presumably,
that's to set the symbol st_target_internal flag for use in
elf32-m68hc1x.c:elf32_m68hc11_relocate_section.
The empty elf32_xgate_relocate_section meant that xgate had no linker.
Or at least, no linker relocation processing. Deleting the
elf_backend_relocate_section define means the target will now use the
generic linker reloc processing. How good that is will depend on the
accuracy of the reloc howtos..
I haven't updated the ld testsuite to xfail tests expected to fail
for generic elf targets.

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.

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
0: 00000000 0 NOTYPE LOCAL DEFAULT UND
1: 0000000d 0 FUNC GLOBAL DEFAULT UND bar
2: 00000001 0 FUNC GLOBAL DEFAULT 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.

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.

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.

sometimes with a hyphen (short-sighted) and sometimes as one word
(eyelashes). Often new compounds are written as two separate words and,
as they become more familiar, they are either connected with a hyphen
(-) or made into one word."
I think command-line X is common enough in our industry that the two
workds command and line should be connected. Since command-line is more
common than commandline, I propose to update binutils documentation to
consistently use "command-line" when this is used as an adjective to a
noun (eg. command-line argument, command-line switch, command-line
option and command-line flag). I've left occurences of "the command
line" as is. I've also left gdb, sim and readline alone and have only
touched public documentation (texi and NEWS files).

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.

Remove:
FAIL: DT_TEXTREL map file warning
introduced with commit 63c1f59d6655 ("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 7403cb6305f5 ("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.

When trying to run the update-gnulib.sh script in gdb, I get this:
Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1.
Aborting.
Apparently, it's an issue with a regex in automake that triggers a
warning starting with Perl 5.22. It has been fixed in automake 1.15.1.
So I think it's a good excuse to bump the versions of autoconf and
automake used in the gnulib import. And to avoid requiring multiple
builds of autoconf/automake, it was suggested that we bump the required
version of those tools for all binutils-gdb.
For autoconf, the 2.69 version is universally available, so it's an easy
choice. For automake, different distros and distro versions have
different automake versions. But 1.15.1 seems to be the most readily
available as a package. In any case, it's easy to build it from source.
I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ,
because I don't think they are useful in our case. They only specify a
lower bound for the acceptable version of automake/autoconf. That's
useful if you let the user choose the version of the tool they want to
use, but want to set a minimum version (because you use a feature that
was introduced in that version). In our case, we force people to use a
specific version anyway. For the autoconf version, we have the check in
config/override.m4 that enforces the version we want. It will be one
less thing to update next time we change autotools version.
I hit a few categories of problems that required some changes. They are
described below along with the chosen solutions.
Problem 1:
configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated. For more info, see:
configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation
Solution 1:
Adjust the code based on the example at that URL.
Problem 2 (in zlib/):
Makefile.am: error: required file './INSTALL' not found
Makefile.am: 'automake --add-missing' can install 'INSTALL'
Makefile.am: error: required file './NEWS' not found
Makefile.am: error: required file './AUTHORS' not found
Makefile.am: error: required file './COPYING' not found
Makefile.am: 'automake --add-missing' can install 'COPYING'
Solution 2:
Add the foreign option to AUTOMAKE_OPTIONS.
Problem 3:
doc/Makefile.am:20: error: support for Cygnus-style trees has been removed
Solution 3:
Remove the cygnus options.
Problem 4:
Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')
Solution 4:
Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is
already defined earlier).
Problem 5:
doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead
doc/Makefile.am: warning: Oops!
doc/Makefile.am: It appears this file (or files included by it) are triggering
doc/Makefile.am: an undocumented, soon-to-be-removed automake hack.
doc/Makefile.am: Future automake versions will no longer place in the builddir
doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that
doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or
doc/Makefile.am: DISTCLEANFILES.
doc/Makefile.am: If you want your '.info' files to be placed in the builddir
doc/Makefile.am: rather than in the srcdir, you have to use the shiny new
doc/Makefile.am: 'info-in-builddir' automake option.
Solution 5:
Rename .texinfo files to .texi.
Problem 6:
doc/Makefile.am: warning: Oops!
doc/Makefile.am: It appears this file (or files included by it) are triggering
doc/Makefile.am: an undocumented, soon-to-be-removed automake hack.
doc/Makefile.am: Future automake versions will no longer place in the builddir
doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that
doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or
doc/Makefile.am: DISTCLEANFILES.
doc/Makefile.am: If you want your '.info' files to be placed in the builddir
doc/Makefile.am: rather than in the srcdir, you have to use the shiny new
doc/Makefile.am: 'info-in-builddir' automake option.
Solution 6:
Remove the hack at the bottom of doc/Makefile.am and use
the info-in-builddir automake option.
Problem 7:
doc/Makefile.am:35: error: required file '../texinfo.tex' not found
doc/Makefile.am:35: 'automake --add-missing' can install 'texinfo.tex'
Solution 7:
Use the no-texinfo.tex automake option. We also have one in
texinfo/texinfo.tex, not sure if we should point to that, or move it
(or a newer version of it added with automake --add-missing) to
top-level.
Problem 8:
Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory,
Makefile.am:131: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output
automake: object file(s) will be placed in the top-level directory. However,
automake: this behaviour will change in future Automake versions: they will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.
Solution 8:
Use subdir-objects, that means adjusting references to some .o that will now
be in config/.
Problem 9:

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.

As from commit 2ebd05b80b22 ("MIPS/LD: Correct `mips-*-windiss' target
emulation configuration") we have:
EXTRA_EM_FILE=mipself
in `emulparams/elf32mipswindiss.sh', however no corresponding Makefile
`mipself.em' dependency for `eelf32mipswindiss.c'. Add it.
ld/
* Makefile.am (eelf32mipswindiss.c): Add `mipself.em' dependency.
* Makefile.in: Regenerate.
