As described in PR ld/32580, when using SHELL=/bin/sh or /bin/ksh on
Solaris, the generated linker scripts get corrupted. So far, the only
workaround is to enforce /bin/bash instead.
This is a major nuisance for developers and users alike, so this patch
automates this by overriding SHELL in ld/configure.ac.
Tested on amd64-pc-solaris2.11 in three configurations:
* CONFIG_SHELL unset
* CONFIG_SHELL=/bin/ksh
* CONFIG_SHELL='/bin/bash --norc'
In the first two cases, SHELL was set to /bin/bash as desired, while in
the third it was left unchanged.

Swap AM_PO_SUBDIRS and ZW_GNU_GETTEXT_SISTER_DIR lines in
*/configure.ac. ZW_GNU_GETTEXT_SISTER_DIR indirectly invokes
AC_REQUIRE(AM_PO_SUBDIRS) so results in AM_PO_SUBDIRS being emitted
before ZW_GNU_GETTEXT_SISTER_DIR if it hasn't already been invoked.

We have a discrepancy with 64-bit BFD handling across our component
subdirectories leading to link failures such as:
ld: ../opcodes/.libs/libopcodes.a(disassemble.o): in function `disassembler': disassemble.c:(.text+0x65): undefined reference to `print_insn_alpha'
ld: disassemble.c:(.text+0x105): undefined reference to `print_insn_ia64'
ld: disassemble.c:(.text+0x11d): undefined reference to `print_insn_loongarch'
ld: disassemble.c:(.text+0x1a1): undefined reference to `print_insn_big_mips'
[...]
with some configurations having a 32-bit host and 64-bit BFD, such as:
`--host=i386-linux-gnu --target=riscv64-linux-gnu --enable-targets=all'.
This is ultimately due to how 64-bit BFD is enabled for bfd/ itself and
other subdirectorses and has been a regression from commit 1d5269c994bf
("unify 64-bit bfd checks").
For bfd/ the BFD_64_BIT autoconf macro from config/bfd64.m4 is used
combined with this logic in bfd/configure.ac:
case ${host64}-${target64}-${want64} in
*true*)
wordsize=64
bfd64_libs='$(BFD64_LIBS)'
all_backends='$(BFD64_BACKENDS) $(BFD32_BACKENDS)'
[...]
;;
false-false-false)
wordsize=32
all_backends='$(BFD32_BACKENDS)'
;;
esac
where the value of ${wordsize} switches between 32-bit and 64-bit BFD
via these pieces:
#define BFD_ARCH_SIZE @wordsize@
and:
#if BFD_ARCH_SIZE >= 64
#define BFD64
#endif
in bfd/bfd-in.h, which ultimately becomes a part of "bfd.h".
Then ${host64} is determined in bfd/configure.ac from the host's word
size, via the host's pointer size:
if test "x${ac_cv_sizeof_void_p}" = "x8"; then
host64=true
fi
And ${target64} is determined in bfd/configure.ac from the target's word
size:
if test ${target_size} = 64; then
target64=true
fi
Where multiple targets have been requested with `--enable-targets=all'
the presence of any 64-bit target will set "true" here.
Finally ${want64} is set according to `--enable-64-bit-bfd' user option
with an arrangement involving BFD_64_BIT:
BFD_64_BIT
if test $enable_64_bit_bfd = yes ; then
want64=true
else
want64=false
fi
which also, redundantly, checks and sets its result upon the host's word
size. Lastly ${want64} is also selectively set by target fragments in
bfd/config.bfd, which mostly if not completely overlaps with ${target64}
setting as described above.
Conversely other subdirectories only rely on BFD_64_BIT, so they fail to
notice that BFD is 64-bit and do not enable their 64-bit handling where
the host requested is 32-bit and 64-bit BFD has been enabled other than
with `--enable-64-bit-bfd'. One consequence is opcodes/disassemble.c
enables calls to its numerous own 64-bit backends by checking the BFD64
macro from "bfd.h", however does not actually enable said backends in
its Makefile. Hence the link errors quoted above.
Address the problem then by moving the `--enable-64-bit-bfd' option back
to bfd/configure.ac and remove the call to BFD_64_BIT from there and
then rewrite the macro in terms of checking for the presence of BFD64
macro in "bfd.h", which is the canonical way of determining whether BFD
is 64-bit or not.
Rather than running `grep' directly on ../bfd/bfd-in3.h as the opcodes/
fragment used to before the problematic commit:
if grep '#define BFD_ARCH_SIZE 64' ../bfd/bfd-in3.h > /dev/null; then
run the preprocessor on "bfd.h", which allows to invoke the macro from
configure.ac files placed in subdirectories located at deeper levels, by
relying on the preprocessor's search path.
This requires however that the invokers rely on `all-bfd' rather than
`configure-bfd' for their `configure' invocation stage, because "bfd.h"
is made by `make all' rather than `configure' in bfd/.
Do not cache the result of this check however, as reconfiguring a tree
such as to flip `--enable-64-bit-bfd' on or to change a secondary target
may affect BFD64 and we have no access to information about secondary
targets in BFD_64_BIT.
Also remove the ENABLE_BFD_64_BIT automake conditional, as it's not used
anywhere.
Last but not least remove the hack from gdb/configure.ac to fail builds
for `mips*-*-*' hosts where `--enable-targets=all' has been requested,
but `--enable-64-bit-bfd' has not as it's no longer needed. Such builds
complete successfully now, having enabled 64-bit BFD implicitly.

The is patch adds a new ld build-id computation mode, "xx", using
xxhash in its 128-bit mode. The patch prereqs the xxhash-devel
headers being installed, and uses the "all-inlined" model, so no
run-time or link-time library dependence exists.
The xxhash mode performs well, saving roughly 20% of total userspace
run time from an ld job over a 800MB shared library relative to sha1.
128 bits of good hash should be collision-resistant to a number of
distinct binaries that numbers in the 2**32 - 2**64 range, even if not
"crypto" level hash. Confirmations of this are in progress.
ld/configury: add --with-xxhash mode, different from gdb case
because only using it in inline mode
ld/ldbuildid.c: add "xx" mode, #if WITH_XXHASH
ld/NEWS, ld.texi: mention new option
ld/lexsup.c: add enumeration of --build-id STYLES to --help
ld/testsuite/ld-elf/build-id.exp: add test case for 0xHEX case
and conditional for xx case;
also, simply tcl list syntax

The linker merges all the input .sframe sections. When merging, the
linker verifies that all the input .sframe sections have the same
abi/arch.
The linker uses libsframe library to perform key actions on the
.sframe sections - decode, read, and create output data. This
implies buildsystem changes to make and install libsframe before
libbfd.
The linker places the output .sframe section in a new segment of its
own: PT_GNU_SFRAME. A new segment is not added, however, if the
generated .sframe section is empty.
When a section is discarded from the final link, the corresponding
entries in the .sframe section for those functions are also deleted.
The linker sorts the SFrame FDEs on start address by default and sets
the SFRAME_F_FDE_SORTED flag in the .sframe section.
This patch also adds support for generation of SFrame unwind
information for the .plt* sections on x86_64. SFrame unwind info is
generated for IBT enabled PLT, lazy/non-lazy PLT.
The existing linker option --no-ld-generated-unwind-info has been
adapted to include the control of whether .sframe unwind information
will be generated for the linker generated sections like PLT.
Changes to the linker script have been made as necessary.

gas uses ZSTD_compressStream2 which is only available with libzstd >=
1.4.0, leading to build errors when an older version is installed.
This patch updates the check libzstd presence to check its version is
>= 1.4.0. However, since gas seems to be the only component requiring
such a recent version this may imply that we disable ZSTD support for
all components although some would still benefit from an older
version.
I ran 'autoreconf -f' in all directories containing a configure.ac
file, using vanilla autoconf-2.69 and automake-1.15.1. I noticed
several errors from autoheader in readline, as well as warnings in
intl, but they are unrelated to this patch.
This should fix some of the buildbots.
OK for trunk?
Thanks,
Christophe

PR29397 PR29563: Add new configure option --with-zstd which defaults to

* gdb: support ELFCOMPRESS_ZSTD input. The bfd change references zstd

If zstd is not supported, ELFCOMPRESS_ZSTD input triggers an error. We
can avoid HAVE_ZSTD if binutils-gdb imports zstd/ like zlib/, but this
is too heavyweight, so don't do it for now.

Using AS_IF rather than shell "if" is recommended for conditionals
that contain non-trivial autoconf macros, because autoconf will emit
any AC_REQUIREd autoconf macro expansions outside of the conditional.
This makes them available elsewhere in the configure script.

Some components of GNU Binutils will pass "-Wstack-usage=262144" when
"GCC >= 5.0" is detected. However, Clang does not support "-Wstack-usage",
despite that related configuration part in bfd/warning.m4 handles the latest
Clang (15.0.0 as of this writing) as "GCC >= 5.0".
The option "-Wstack-usage" was ignored when the first version of Clang is
released but even this "ignoring" behavior is removed before Clang 4.0.0.
So, if we give Clang "-Wstack-usage=262144", it generates a warning, making
the build failure.
This commit checks "__clang__" macro to prevent adding the option if the
compiler is identified as Clang.

Generate a .note.package FDO package metadata ELF note, following
the spec: https://systemd.io/ELF_PACKAGE_METADATA/
If the jansson library is available at build time (and it is explicitly
enabled), link ld to it, and use it to validate that the input is
correct JSON, to avoid writing garbage to the file. The
configure option --enable-jansson has to be used to explicitly enable
it (error out when not found). This allows bootstrappers (or others who
are not interested) to seamlessly skip it without issues.

Make ld and bfd values consistent by swapping values 0 and 2 in
link_info.warn_execstack. This has the benefit of making the value an
"extended" boolean, with 0 meaning no warning, 1 meaning warn, other
values a conditional warning.
Yes, this patch introduces fails on arm/aarch64. Not a problem with
this patch but an arm/aarch64 before_parse problem.

My previous nm patch handled all cases but one -- if the user set NM in
the environment to a path which contained an option, libtool's nm
detection tries to run nm against a copy of nm with the options in it:
e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the
test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle".
This is unlikely to be desirable: in this case we should run
"/usr/bin/nm --blargle /usr/bin/nm".
Furthermore, as part of this nm has to detect when the passed-in $NM
contains a path, and in that case avoid doing a path search itself.
This too was thrown off if an option contained something that looked
like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run
"nm -B../prev-gcc nm" which rarely works well (and indeed it looks
to see whether that nm exists, finds it doesn't, and wrongly concludes
that nm -p or whatever does not work).
Fix all of these by clipping all options (defined as everything
including and after the first " -") before deciding whether nm
contains a path (but not using the clipped value for anything else),
and then removing all options from the path-modified nm before
looking to see whether that nm existed.
NM=my-nm now does a path search and runs e.g.
/usr/bin/my-nm -B /usr/bin/my-nm
NM=/usr/bin/my-nm now avoids a path search and runs e.g.
/usr/bin/my-nm -B /usr/bin/my-nm
NM="my-nm -p../wombat" now does a path search and runs e.g.
/usr/bin/my-nm -p../wombat -B /usr/bin/my-nm
NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search:
../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm
This seems to be all combinations, including those used by GCC bootstrap
(which, before this commit, fails to bootstrap when configured
--with-build-config=bootstrap-lto, because the lto plugin is now using
--export-symbols-regex, which requires libtool to find a working nm,
while also using -B../prev-gcc to point at the lto plugin associated
with the GCC just built.)
Regenerate all affected configure scripts.
* libtool.m4 (LT_PATH_NM): Handle user-specified NM with
options, including options containing paths.
