New point version
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[=<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). 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.
