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.

* 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

x86: Disallow TLS relocation in non executable section
|
|
|
|
Since TLS relocations are applied to executable machine instructions,
|
|
disallow TLS relocation in non-SHT_PROGBITS, non-SHF_EXECINSTR section.

|
|
* elf32-i386.c (elf_i386_tls_transition): Disallow TLS relocation
|
|
in non-SHT_PROGBITS, non-SHF_EXECINSTR section.
|
|
(elf_i386_scan_relocs): Likewise.
|
|
* elf64-x86-64.c (elf_x86_64_tls_transition): Likewise.
|
|
(elf_x86_64_scan_relocs): Likewise.
|
|
* elfxx-x86.c (_bfd_x86_elf_link_report_tls_invalid_section_error):
|
|
New.
|
|
* elfxx-x86.h (_bfd_x86_elf_link_report_tls_invalid_section_error):
|
|
Likewise.
