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.) + Changes in 2.44: * Support for Nios II targets has been removed except in the readelf utility, |
