Lets try for some build results in staging.
- Update to version 2.45:
* New versioned release of libsframe.so.2
* s390: tools now support SFrame format 2; recognize "z17" as CPU
name [bsc#1247105, jsc#IBM-1485]
* sframe sections are now of ELF section type SHT_GNU_SFRAME.
* sframe secions generated by the assembler have
SFRAME_F_FDE_FUNC_START_PCREL set.

sha v1.0, zce v1.0, smcdeleg v1.0, ssccfg v1.0, svvptc v1.0, zilsd v1.0,
zclsd v1.0, smrnmi v1.0;
vendor: CORE-V, xcvbitmanip v1.0 and xcvsimd v1.0;

T-Head: xtheadvdot v1.0;
MIPS: xmipscbop v1.0, xmipscmov v1.0, xmipsexectl v1.0, xmipslsp v1.0.
* Support RISC-V privileged version 1.13, profiles 20/22/23, and
.bfloat16 directive.
* x86: Add support for these ISAs: Intel Diamond Rapids AMX, MOVRS,
AVX10.2 (including SM4), MSR_IMM; Zhaoxin PadLock PHE2, RNG2, GMI, XMODX.
Drop support for AVX10.2 256 bit rounding.
* arm: Add support for most of Armv9.6, enabled by -march=armv9.6-a and
extensions '+cmpbr', '+f8f16mm', '+f8f32mm', '+fprcvt', '+lsfe', '+lsui',
'+occmo', '+pops', '+sme2p2', '+ssve-aes', '+sve-aes', '+sve-aes2',
'+sve-bfscale', '+sve-f16f32mm' and '+sve2p2'.
* Predefined symbols "GAS(version)" and, on non-release builds, "GAS(date)"
are now being made available.
* Add .errif and .warnif directives.
* linker:
- Add --image-base=<ADDR> option to the ELF linker to behave the same

elf: Don't match corrupt section header in linker input
|
|
|
|
Don't swap in nor match corrupt section header in linker input to avoid
|
|
linker crash later.
|
|
|
|
PR ld/33457
|
|
* elfcode.h (elf_swap_shdr_in): Changed to return bool. Return
|
|
false for corrupt section header in linker input.
|
|
(elf_object_p): Reject if elf_swap_shdr_in returns false.
