  • Subject: GNU Binutils 2.33.1 has been released.

Hello Everyone,

  We are pleased to announce that version 2.33.1 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/

  The md5sum values are:

  This release contains numerous bug fixes, and also the following new
  features:

    Assembler:
    
    * Adds support for the Arm Scalable Vector Extension version 2
      (SVE2) instructions, the Arm Transactional Memory Extension (TME)
      instructions and the Armv8.1-M Mainline and M-profile Vector
      Extension (MVE) instructions.

    * Adds support for the Arm Cortex-A76AE, Cortex-A77 and Cortex-M35P
      processors and the AArch64 Cortex-A34, Cortex-A65, Cortex-A65AE,
      Cortex-A76AE, and Cortex-A77 processors.

    * Adds a .float16 directive for both Arm and AArch64 to allow
      encoding of 16-bit floating point literals.

    * For MIPS, Add -m[no-]fix-loongson3-llsc option to fix (or not)
      Loongson3 LLSC Errata.  Add a --enable-mips-fix-loongson3-llsc=[yes|no]
      configure time option to set the default behavior. Set the default
      if the configure option is not used to "no".

    Linker:

    * The Cortex-A53 Erratum 843419 workaround now supports a choice of
      which workaround to use.  The option --fix-cortex-a53-843419 now
      takes an optional argument --fix-cortex-a53-843419[=full|adr|adrp]
      which can be used to force a particular workaround to be used.
      See --help for AArch64 for more details.

    * Add support for GNU_PROPERTY_AARCH64_FEATURE_1_BTI and
      GNU_PROPERTY_AARCH64_FEATURE_1_PAC  in ELF GNU program properties
      in the AArch64 ELF linker. 

    * Add -z force-bti for AArch64 to enable GNU_PROPERTY_AARCH64_FEATURE_1_BTI
      on output while warning about missing GNU_PROPERTY_AARCH64_FEATURE_1_BTI 
      on inputs and use PLTs protected with BTI.

    * Add -z pac-plt for AArch64 to pick PAC enabled PLTs.

    Utilities:

    * Add --source-comment[=] option to objdump which if present,
      provides a prefix to source code lines displayed in a disassembly.

    * Add --set-section-alignment=
      option to objcopy to allow the changing of section alignments.

    * Add --verilog-data-width option to objcopy for verilog targets to
      control width of data elements in verilog hex format.

    * The separate debug info file options of readelf (--debug-dump=links
      and --debug-dump=follow) and objdump (--dwarf=links and
      --dwarf=follow-links) will now display and/or follow multiple
      links if more than one are present in a file.  (This usually
      happens when gcc's -gsplit-dwarf option is used).

      In addition objdump's --dwarf=follow-links now also affects its
      other display options, so that for example, when combined with
      --syms it will cause the symbol tables in any linked debug info
      files to also be displayed.  In addition when combined with
      --disassemble the --dwarf=follow-links option will ensure that
      any symbol tables in the linked files are read and used when
      disassembling code in the main file.

    * Add support for dumping types encoded in the Compact Type Format
      to objdump and readelf.    

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

  Note in case you are wondering about what happened to the 2.33
  release, it is stuck pending the resolution of an issue with the keys
  used to sign the release.  Once this is resolved the 2.33 tarballs
  will be uploaded, even though they will now be slightly out of date.

Cheers
  Nick Clifton
  Binutils Chief Maintainer.
