GNU Binutils 2.33
Fedora 32 comes with GNU Binutils based on 2.33.1 release. This release brings a lot of bug fixes, improvements to the linker, as well as support for the CTF debug format.
New Features and Bug Fixes:
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).
Add support for dumping types encoded in the Compact Type Format to objdump and readelf.
