Hi Everyone,

We are pleased to announce that version 2.43 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/

This time we are also including tarballs compressed with the zstd program.

As an experiment these tarballs were made with the new "-r <date>"
option supported by the src-release.sh script. This attempts to make
reproducible tarballs by sorting the files and passing the
"--mtime=<date>" 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:

Assembler:

* Add a .base64 directive to the assembler which allows base64 encoded
binary data to be provided as strings.

* Assembler macros as well as the bodies of .irp / .irpc / .rept can now use
the syntax \+ to access the number of times a given macro has been executed.
This is similar to the already existing \@ syntax, except that the count is
maintained on a per-macro basis.

* References to FB and dollar labels, when supported, are no longer permitted
in a radix other than 10. (Note that definitions of such labels were
already thus restricted, except that leading zeroes were permitted).

Linker:

* Add support for DT_RELR type compressed runtime relocations for the
AArch64 and LoongArch architectures.

* Add --rosegment option which changes the -z separate-code option so that
only one read-only segment is created (instead of two).

* Add --section-ordering-file <FILE> option to add extra mapping of input
sections to output sections.

* Add -plugin-save-temps to store plugin intermediate files permanently.

Utilities:

* Readelf will now display DT_RELR relocations in full detail.

* Readelf now has a -j/--display-section option which takes the name
or index of a section and displays its contents according to its
type. The option can be used multiple times on the command line to
display multiple sections.

* When objdump or readelf are used to display the contents of a
.eh_frame section they will now also display the contents of the
.eh_frame_hdr section, if present.

Gprofng:

* Improved the support for hardware event counters:
- Re-designed and streamlined the implementation.
- Defined a common set of events for ARM processors.
- Added specific events for AMD ZEN3 / ZEN4, and Intel
Ice Lake processors.
* Added a minimal support for RISC-V.

General:

* Target specific improvements for many architectures. For more
information see:

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