- 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.

This is for userspace live patching, adding some space into
|
|

shared libs or executable (in the .ulp section) when one of the

input files contains a section named .ulp.track.

Subject: ld: Avoid overflows in string merging
|
|
||||||
To: binutils@sourceware.org
|
|
||||||
|
|
||||||
as the bug report shows we had an overflow in the test if
|
|
||||||
hash table resizing is needed. Reorder the expression to avoid
|
|
||||||
that. There's still a bug somewhere in gracefully handling
|
|
||||||
failure in resizing (e.g. out of memory), but this pushes the
|
|
||||||
boundary for that occurring somewhen into the future and
|
|
||||||
immediately helps the reporter.
|
|
||||||
|
|
||||||
bfd/
|
|
||||||
|
|
||||||
PR ld/31009
|
|
||||||
* merge.c (NEEDS_RESIZE): New macro avoiding overflow.
|
|
||||||
(sec_merge_maybe_resize): Use it.
|
|
||||||
(sec_merge_hash_insert): Ditto.

Subject: bfd: use less memory in string merging
|
|
||||||
To: binutils@sourceware.org
|
|
||||||
|
|
||||||
the offset-to-entry mappings are allocated in blocks, which may
|
|
||||||
become a bit wasteful in case there are extremely many small
|
|
||||||
input files or sections. This made it so that a large project
|
|
||||||
(Qt5WebEngine) didn't build anymore on x86 32bit due to address
|
|
||||||
space limits. It barely fit into address space before the new
|
|
||||||
string merging, and then got pushed over the limit by this.
|
|
||||||
|
|
||||||
So instead of leaving the waste reallocate the maps to their final
|
|
||||||
size once known. Now the link barely fits again.
|
|
||||||
|
|
||||||
bfd/
|
|
||||||
* merge.c (record_section): Reallocate offset maps to their
|
|
||||||
final size.

Tue Jan 30 13:52:11 UTC 2024 - Michael Matz <matz@suse.com>
|
||||||
|
|
||||||
|
- 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.
|
||||||
|
- Add binutils-2.42-branch.diff.gz.
|
||||||
|
- Rebased s390-biarch.diff.
|
||||||
|
- Removed binutils-2.41-branch.diff.gz, binutils-2.41.tar.bz2,
|
||||||
|
binutils-2.41-branch.diff.gz.
|
||||||
|
- Removed binutils-use-less-memory.diff and riscv-relro.patch
|
||||||
|
(both upstreamed).
|
||||||
|
- Removed add-ulp-section.diff, we use a different mechanism
|
||||||
|
for live patching since a long time.
