Hi Everyone, We are pleased to announce that version 2.45 of the GNU Binutils project sources have been released and are now available for download at:
https://ftp.gnu.org/gnu/binutils https://sourceware.org/pub/binutils/releases/ The sha256 checksums are: 1393f90db70c2ebd785fb434d6127f8888c559d5eeb9c006c354b203bab3473e binutils-2.45.tar.bz2 8a3eb4b10e7053312790f21ee1a38f7e2bbd6f4096abb590d3429e5119592d96 binutils-2.45.tar.gz 17a71cbe6cd31f6b2237a15a8a413d234c2d664d1df1df48f4f12fab8023324c binutils-2.45.tar.lz c50c0e7f9cb188980e2cc97e4537626b1672441815587f1eab69d2a1bfbef5d2 binutils-2.45.tar.xz 7f288c9a869582d53dc645bf1b9e90cc5123f6862738850472ddbca69def47a3 binutils-2.45.tar.zst These tarballs were made with the "-r <date>" option supported by the src-release.sh script. This attempts to make reproducible tarballs by sorting the files and passing the "--mtime=<date>" option to tar. The date used for these tarballs was obtained by running: git log -1 --format=%cd --date=format:%F bfd/version.m4 As this is an odd numbered release, the sources for the GOLD linker are *not* included. This release contains numerous bug fixes, and also the following new features: Assembler: All sframe information generated by the assembler is now in compliance with the SFrame V2 specification. The assembler now supports .errif and .warnif directives, permitting user-controlled diagnostics with conditionals that are evaluated only at the end of assembly. The assembler predefines the symbol "GAS(version)". The assembler now supports the generation of SFrame stack trace information (.sframe) from CFI directives on s390 64-bit (s390x). For RISC-V, the ".option arch, -ext" format is deprecated due to its controversial use. For RISC-V, stop generating mapping symbols $x and replace with $x<isa>. The $x was defined to have the same ISA as previous $x<isa>, but now is defined to have the same ISA as elf architecture attribute. Once both used .option arch/rvc/norvc/push/pop directives (some code have different architectures with file attribute) and data directives in text, then the file need to be rebuilt since 2.45. The assembler supports the latest architecture extensions for the RISC-V, LoongArch and AArch64 architectures. Linker: The linker's --stats option can take an optional argument which if used is interpreted as a filename into which resource usage information should be stored. As an alternative mechanism the LD_STATS environment variable can also be used to achieve the same results. Resource usage information for various phases of the linking operation is now included in the report. If a map file is being produced then the information is also included there. The --no-stats option can be used to disable stat reporting, should it have been enabled. On s390 64-bit (s390x), generate SFrame stack trace information (.sframe) for the linker generated .plt section. On s390 32-bit, generate ".eh_frame" unwind information for the linker generated .plt section. Both features are enabled by default and can be disabled using linker option --no-ld-generated-unwind-info. On RISC-V, add new PLT formats, and GNU property merge rules for zicfiss and zicfilp extensions. On AVR, the default linker scripts now assert that the .progmem sections don't extend past 0xffff since they are accessed by means of LPM. For data in program memory that may be located past 0xffff, a .progmemx section should be used. On LoongArch, linker relaxation time complexity is no longer quadratic with respect to relocation counts. Linking time of large software should be improved. In addition R_LARCH_32_PCREL records are now checked for overflow. Other binary utilities: 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. 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. 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.)
