We bring patches 0001 and 0002 that we carry for binutils 2.44. Patch
0002 requires a small update as a nearby configure option has been
removed between 2.44 and 2.45. Patch 0003 that we have for binutils
2.44 is not needed as it is part of the 2.45 release.
Changes in 2.45:
* New versioned release of libsframe: libsframe.so.2. This release introduces
versioned symbols with version node name LIBSFRAME_2.0. Some new symbols
have been added to support the new flag SFRAME_F_FDE_FUNC_START_PCREL and
retrieving flags from SFrame decoder and encoder objects:
- Addition of sframe_decoder_get_flags,
sframe_decoder_get_offsetof_fde_start_addr, sframe_encoder_get_flags,
sframe_encoder_get_offsetof_fde_start_addr.
This release also includes backward-incompatible ABI changes:
- Removal of sframe_get_funcdesc_with_addr.
- Change in the behavior of sframe_decoder_get_funcdesc_v2,
sframe_encoder_add_funcdesc_v2 and sframe_encoder_write.
* On s390 64-bit (s390x), gas, ld, objdump, and readelf now support generating
and processing SFrame V2 stack trace information (.sframe). The assembler
generates SFrame info from CFI directives with option "--gsframe". The
linker generates SFrame info for the linker-generated .plt section and merges
all .sframe sections. Both objdump and readelf dump SFrame info with option
"--sframe[=<section-name>]".
* For SFrame stack trace format, the function start address in each SFrame
FDE has a changed encoding: The 32-bit signed integer now holds the offset
of the start PC of the associated function from the sfde_func_start_address
field itself (instead of the earlier where it was the offset from the start
of the SFrame section itself). All SFrame sections generated by gas and ld
now default to this new encoding, setting the (new)
SFRAME_F_FDE_FUNC_START_PCREL flag.
Relocatable SFrame links are now fixed.
* Readelf now recognizes RISC-V GNU_PROPERTY_RISCV_FEATURE_1_CFI_SS and
GNU_PROPERTY_RISCV_FEATURE_1_CFI_LP_UNLABELED for zicfiss and zicfilp
extensions.
* For RISC-V dis-assembler, the definition of mapping symbol $x is changed,
so the file needs to be rebuilt since 2.45 once used .option arch directives.
* The LoongArch disassembler now properly accepts multiple disassembly
options given by -M, such as "-M no-aliases,numeric". (Previously only the
first option took effect.)
