  "message": "[SFrame-V3] include: gas: libsframe: add 8-bits of func_info2 for extensibility in FDE\n\nThe existing field func_info (in the SFrame FDE) is used to convey important\ninformation around the encoding and interpretation of the rest of the\nstack trace data for the respective SFrame FDE: the SFrame FRE type,\nSFrame FDE PC type, etc.\n\nCurrently there is 1 bit left for AArch64, and 2 bits for AMD64, s390x\n(and other future ABIs to be supported).  Provision some additional\nspace now (specifically an additional 8-bits) for future needs for V3\nand beyond.\n\nCompared to V2, this now increases the size of SFrame FDE by 1 byte in\nV3.  In this patch, the additional func_info2 byte is not used\nfunctionally yet.  Hence, rather mechanical changes in libsframe, bfd\nand libsframe/testsuite accompany.  We will put func_info2 into use in a\nlater patch by reserving 5 of these bits for SFrame FDE types.\n\nWith the addition of a new byte for additional func info (func_info2),\nadd a new arg to allow usecases like textual dumper to get all data\nmembers in one API: sframe_decoder_get_funcdesc_v3.  To keep the APIs\nsymmetric looking, add new arg to sframe_encoder_add_funcdesc_v3 too.\n\nSince bfd uses these APIs, carry out the mechanical change in the\nrespective APIs too.  And of course, the testsuite which exercises these\nAPIs.\n\nbfd/\n\t* elf-sframe.c (_bfd_elf_merge_section_sframe): Get and set\n\tfunc_info2.\n\t* elf64-s390.c (_bfd_s390_elf_create_sframe_plt): Pass 0 for\n\tfunc_info2 for SFrame FDE for PLT.\n\t* elfxx-x86.c (_bfd_x86_elf_create_sframe_plt): Likewise.\ngas/\n\t* gen-sframe.c (output_sframe_funcdesc): Emit the uint8_t for\n\tfunc_info2.\nlibsframe/\n\t* sframe-dump.c (dump_sframe_func_with_fres):\n\t* sframe.c (sframe_fde_tbl_init): Handle the new additional\n\tmember.\n\t(sframe_encoder_write_fde): Likewise.\n\t* sframe.c (sframe_decoder_get_funcdesc_v3): Update func_info2.\nlibsframe/testsuite/\n\t* libsframe.decode/DATA2: Update data file with SFrame section\n\tdata.\n\t* libsframe.encode/encode-1.c: Pass 0 for func_info2 arg.\n\t* libsframe.find/findfre-1.c: Likewise.\n\t* libsframe.find/findfunc-1.c: Likewise.\n\t* libsframe.find/plt-findfre-1.c: Likewise.\n\t* libsframe.find/plt-findfre-2.c: Likewise.\ninclude/\n\t* sframe.h: Add new uint8_t sfde_func_info2 to\n\tsframe_func_desc_entry_v3.\n\t* sframe-api.h (sframe_decoder_get_funcdesc_v3): New arg.\n\t(sframe_encoder_add_funcdesc_v3): Likewise.\n",
