GNU Binutils 2.33

Fedora 43 viene con GNU Binutils basada en la liberación 2.33.1 Esta liberación trae un montón de defectos corregidos, mejoras para el enlazador, así como soporte para el formato de depuración CTF.

Características Nuevas y Reparaciones de Defectos:

Ensamblador

  • Añade soporte para las instrucciones de la versión 2 de Arm Scalable Vector Extension (SVE2), las instrucciones del ARM Transactional Memory Extension (TME) y la línea principal de Arm8.1-M y las instrucciones de M-profile en Vector Extension (MVE).

  • Añade asistencia para los procesadores Arm Cortex-A76AE, Cortex-A77 y Cortex-M35P y los procesadores AArch64 Cortex-A34, Cortex-A65, Cortex-A65AE, Cortex-A76AE, y Cortex-A77.

  • 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[=<txt>] option to objdump which if present, provides a prefix to source code lines displayed in a disassembly.

  • Add --set-section-alignment <section-name>=<power-of-2-align> 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).

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