|
| |
+ == 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.
|

I wasn't sure what section binutils was supposed to be in, so I put release notes in a new file and created menu entry in Developers section.
Issue #411
