  "message": "gas: elf: binutils: add new section type SHT_GNU_SFRAME\n\nSo far, SFrame sections were of type SHT_PROGBITS.\n\nAs per ELF specification, SHT_PROGBITS indicates that the section holds\ninformation defined by the program, whose format and meaning are\ndetermined solely by the program.\n\nOn the linker side, SHT_PROGBITS should be reserved for the simple \"cat\ncontents after applying relocs\" semantics.\n\nCurrently, the only way to know that a section contains SFrame stack\ntrace data is if consumer checks for section name.  Such a check for\nsection name is not quite conformant to ELF principles.\n\nSome of this was discussed here\nhttps://sourceware.org/pipermail/binutils/2025-March/140181.html\n\nWith this change, the SFrame sections generated by gas, ld will have\nsection type set to SHT_GNU_SFRAME.   The new section type is defined in\nthe SHT_LOOS/SHT_HIOS space.  The SFrame parsing routine\n_bfd_elf_parse_sframe () now admits sections only when the the section\ntype is SHT_GNU_SFRAME.\n\nNo special handling / validation is done at the moment for the case of\nmanual creation of SFrame sections via obj_elf_section ().  Add function\nlevel comments for now to add a note about this.\n\nAlthough the default handling for (sh_type \u003e\u003d SHT_LOOS \u0026\u0026 sh_type \u003c\u003d\nSHT_HIOS) is sufficient when SHT_GNU_SFRAME is in that range, it makes\nsense to add it as a case of its own.\n\nbfd/\n\t* elf-sframe.c (_bfd_elf_parse_sframe): Check if section type is\n\tSHT_GNU_SFRAME.\n\t(_bfd_elf_set_section_sframe): Set SHT_GNU_SFRAME for output\n\tSFrame section.\n\t* elflink.c (obj_elf_section): Use section type for check\n\tinstead of section name.\n\t* elfxx-x86.c: Set SHT_GNU_SFRAME for SFrame sections for\n\t.plt* sections.\n\t* elf.c (bfd_section_from_shdr): Add case for SHT_GNU_SFRAME.\nbinutils/\n\t* readelf.c (get_os_specific_section_type_name): Add\n\tSHT_GNU_SFRAME.\ngas/\n\t* NEWS: Announce emitted SFrame sections have SHT_GNU_SFRAME\n\tset.\n\t* config/obj-elf.c (obj_elf_attach_to_group): Add comments to\n\tindicate no special handling for SFrame yet.\n\t* dw2gencfi.c (cfi_finish): Set SHT_GNU_SFRAME for emitted\n\tSFrame section.\nld/\n\t* NEWS: Announce emitted SFrame sections have SHT_GNU_SFRAME\n\tset.\ngas/testsuite/\n\t* gas/cfi-sframe/cfi-sframe.exp: Add new test.\n\t* gas/cfi-sframe/cfi-sframe-common-1b.d: New test.\n\t* gas/cfi-sframe/cfi-sframe-common-1b.s: New test.\ninclude/\n\t* elf/common.h (SHT_GNU_SFRAME): Add new section type for SFrame\n\tstack trace information.\nlibsframe/doc/\n\t* sframe-spec.texi: Add expected ELF section type.\n",
