binutils-2.38

[Douglas R. Reno]

New minor version

[Bruce Dubbs]

Changes in binutils 2.38:

• elfedit: Add --output-abiversion option to update ABIVERSION.

• Add support for the LoongArch instruction set.

• Tools which display symbols or strings (readelf, strings, nm, objdump) have a new command line option which controls how unicode characters are handled. By default they are treated as normal for the tool. Using --unicode=locale will display them according to the current locale. Using --unicode=hex will display them as hex byte values, whilst --unicode=escape will display them as escape sequences. In addition using --unicode=highlight will display them as unicode escape sequences highlighted in red (if supported by the output device).

• readelf -r dumps RELR relative relocations now.

• Support for efi-app-aarch64, efi-rtdrv-aarch64 and efi-bsdrv-aarch64 has been added to objcopy in order to enable UEFI development using binutils.

• ar: Add --thin for creating thin archives. -T is a deprecated alias without diagnostics. In many ar implementations -T has a different meaning, as specified by X/Open System Interface.

changes in ld:

• Add -z pack-relative-relocs/-z no pack-relative-relocs to x86 ELF linker to pack relative relocations in the DT_RELR section.

• Add support for the LoongArch architecture.

• Add -z indirect-extern-access/-z noindirect-extern-access to x86 ELF linker to control canonical function pointers and copy relocation.

• Add --max-cache-size=SIZE to set the the maximum cache size to SIZE bytes.

Changes in gas:

• Add support for AArch64 system registers that were missing in previous releases.

• Add support for the LoongArch instruction set.

• Add a command-line option, -muse-unaligned-vector-move, for x86 target to encode aligned vector move as unaligned vector move.

• Add support for Cortex-R52+ for Arm.

• Add support for Cortex-A510, Cortex-A710, Cortex-X2 for AArch64.

• Add support for Cortex-A710 for Arm.

• Add support for Scalable Matrix Extension (SME) for AArch64.

• The --multibyte-handling=[allow|warn|warn-sym-only] option tells the assembler what to when it encoutners multibyte characters in the input. The default is to allow them. Setting the option to "warn" will generate a warning message whenever any multibyte character is encountered. Using the option to "warn-sym-only" will make the assembler generate a warning whenever a symbol is defined containing multibyte characters. (References to undefined symbols will not generate warnings).

• Outputs of .ds.x directive and .tfloat directive with hex input from x86 assembler have been reduced from 12 bytes to 10 bytes to match the output of .tfloat directive.

• Add support for 'armv8.8-a', 'armv9-a', 'armv9.1-a', 'armv9.2-a' and 'armv9.3-a' for -march in AArch64 GAS.

• Add support for 'armv8.7-a', 'armv8.8-a', 'armv9-a', 'armv9.1-a', 'armv9.2-a' and 'armv9.3-a' for -march in Arm GAS.

• Add support for Intel AVX512_FP16 instructions.
