Hi Everyone,
We are pleased to announce that version 2.42 of the GNU Binutils project
sources have been released and are now available for download at:
https://ftp.gnu.org/gnu/binutils
https://sourceware.org/pub/binutils/releases/
checksums:

As an experiment these tarballs were made with the new "-r "
option supported by the src-release.sh script. This attempts to make
reproducible tarballs by sorting the files and passing the
"--mtime=" option to tar. The date used for these tarballs was
obtained by running:
git log -1 --format=%cd --date=format:%F bfd/version.m4
This release contains numerous bug fixes, and also the
following new features:
* Experimental support in GAS to synthesize CFI for ABI-conformant,
hand-written asm using the new command line option --scfi=experimental on
x86-64. Only System V AMD64 ABI is supported.
* The readelf program has a new command line option --extra-sym-info which
extends the information displayed by the --symbols option. When enabled
the display will include the name of the section referenced by a symbol's
index field (st_shndx). In the future more information may also be displayed
when this option is enabled.
* objcopy --set-section-flags now supports "large" to set SHF_X86_64_LARGE
for ELF x86-64 objects.
* objdump --visualize-jumps is now supported on s390 architecture.
* The s390 disassembly now optionally includes the instruction description as
comment with the s390-specific disassembler option "insndesc":
- For objdump it can be enabled with "objdump -M insndesc ...".
- In gdb it can be enabled with "set disassembler-options insndesc".
* Add -z mark-plt/-z nomark-plt options to x86-64 ELF linker to mark PLT
entries with DT_X86_64_PLT, DT_X86_64_PLTSZ and DT_X86_64_PLTENT dynamic
tags. Also added --enable-mark-plt configure option to mark PLT entries
by default.
* Support Intel APX relocations.
* On RISC-V, add ld target option --[no-]check-uleb128. Should rebuild the
objects by binutils 2.42 and up if enabling the option and get warnings,
since the non-zero addend of SUB_ULEB128 shouldn't be generated from .uleb128
directives.
* Add support for the KVX instruction set.
* A new linker script sorting directive has been added: REVERSE. This reverses
the order of the sorting. It may be combined with either SORT_BY_NAME or
SORT_BY_INIT_PRIORITY.
* Added --warn-execstack-objects to warn about executable stacks only when an
input object file requests one. Also added --error-execstack and
--error-rxw-segments options to convert warnings about executable stacks and
segments into errors.
Also added --enable-error-execstack=[yes|no] and
--enable-error-rwx-segments=[yes|no] configure options to set the default for
converting warnings into errors.
* On LoongArch, the LoongArch ABI v2.30 (LoongArch ELF psABI v20231219) is
now implemented. This includes new relocation types, and changed
semantics for PC-relative relocations handling the higher half of 64-bit
offsets.
* Add support for more AArch64 architecture extensions.
* Add support for more Intel architecture extensions.
* Add support for more RISC-V architecture extensions.
* The BPF assembler now uses semi-colon (;) to separate statements, and
therefore they cannot longer be used to begin line comments. This matches the
behavior of the clang/LLVM BPF assembler.
* The BPF assembler now allows using both hash (#) and double slash (//) to
begin line comments.

Our thanks go out to all of the binutils contributors, past and
present, for helping to make this release possible.
