- Update to version 2.42:
* Add support for many aarch64 extensions: SVE2.1, SME2.1, B16B16,
RASv2, LSE128, GCS, CHK, SPECRES2, LRCPC3, THE, ITE, D128, XS and
flags to enable them: '+fcma', '+jscvt', '+frintts', '+flagm2',
'+rcpc2' and '+wfxt'
* Add experimantal support for GAS to synthesize call-frame-info for
some hand-written asm (--scfi=experimental) on x86-64.
* Add support for more x86-64 extensions: APX: 32 GPRs, NDD, PUSH2/POP2,
PUSHP/POPP; USER_MSR, AVX10.1, PBNDKB, SM4, SM3, SHA512, AVX-VNNI-INT16.
* Add support for more RISC-V extensions: T-Head v2.3.0, CORE-V v1.0,
SiFive VCIX v1.0.
* BPF assembler: ';' separates statements now, and does not introduce
line comments anymore (use '#' or '//' for this).
* x86-64 ld: Add '-z mark-plt/-z nomark-plt' to mark PLT entries with
dynamic tags.
* risc-v ld: Add '--[no-]check-uleb128'.
* New linker script directive: REVERSE, to be combined with SORT_BY_NAME
or SORT_BY_INIT_PRIORITY, reverses the generated order.
* New linker options --warn-execstack-objects (warn only about execstack
when input object files request it), and --error-execstack plus
--error-rxw-segments to convert the existing warnings into errors.
* objdump: Add -Z/--decompress to be used with -s/--full-contents to
decompress section contents before displaying.
* readelf: Add --extra-sym-info to be used with --symbols (currently
prints section name of references section index).
* objcopy: Add --set-section-flags for x86_64 to include
SHF_X86_64_LARGE.
* s390 disassembly: add target-specific disasm option 'insndesc',
as in "objdump -M insndesc" to display an instruction description
as comment along with the disassembly.
