binutils-2.45

[Xi Ruoyao]

New minor version.

[Bruce Dubbs]

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.)
