Bump version to SFRAME_VERSION_3. Introduce a new definition of SFrame FDE for version 3, which is a duplicate of SFrame FDE in V2, for now. In other words, no changes to the format specification yet. GNU as emits SFrame V3 by default. SFrame encoder (ld) emits SFrame V3 sections. In a later commit, we will add a new command line option to gas: --gsframe-3 which will bind the implementation in gas to emit SFrame V3. Also, adjust the testcases for the new version string "SFRAME_VERSION_3". bfd/ * elf-sframe.c (_bfd_elf_merge_section_sframe): Linker emits the latest version by default. * elf64-s390.c (_bfd_s390_elf_create_sframe_plt): Linker emitted PLT sections are also SFRAME_VERSION_3. * elfxx-x86.c (_bfd_x86_elf_create_sframe_plt): Likewise. gas/ * gen-sframe.c (sframe_set_version): GAS emits SFrame V3 by default. (output_sframe): Likewise. libsframe/ * sframe-dump.c (dump_sframe): Enable dumping for both SFRAME_VERSION_2 and SFRAME_VERSION_3. include/ChangeLog: * sframe.h (SFRAME_VERSION_3): New definition. (SFRAME_VERSION): Current version is now SFRAME_VERSION_3. (SFRAME_V3_FDE_FUNC_INFO): New definition. (SFRAME_V3_FDE_FRE_TYPE): Likewise. (SFRAME_V3_FDE_PC_TYPE): Likewise. (SFRAME_V3_AARCH64_FDE_PAUTH_KEY): Likewise. (SFRAME_V3_FDE_UPDATE_PAUTH_KEY): Likewise. binutils/testsuite/ * all affected tests: Replace SFRAME_VERSION_2 with SFRAME_VERSION_3. gas/testsuite/ * all affected tests: Likewise. ld/testsuite/ * all affected tests: Likewise. libsframe/testsuite/ * all affected tests: Likewise.
