Don't make assumptions on containing section or number of auxiliary entries. PR lto/81968 * simple-object-elf.c (simple_object_elf_copy_lto_debug_section): Adjust field with for sh_type write, set SHF_EXCLUDE only for removed sections. PR lto/81925 * simple-object-elf.c (simple_object_elf_write_shdr): Adjust type of sh_addralign and sh_entsize and properly write sh_entsize as Elf_Addr. (simple_object_elf_write_to_file): Read sh_entsize as Elf_Addr. * simple-object-common.h (struct simple_object_functions): Add copy_lto_debug_sections hook. * simple-object.c: Include fcntl.h. (handle_lto_debug_sections): New helper function. (simple_object_copy_lto_debug_sections): New function copying early LTO debug sections to regular debug sections in a new file. (simple_object_start_write): Handle NULL segment_name. * simple-object-coff.c (simple_object_coff_functions): Adjust for not implemented copy_lto_debug_sections hook. * simple-object-mach-o.c (simple_object_mach_o_functions): Likewise. * simple-object-xcoff.c (simple_object_xcoff_functions): Likewise. * simple-object-elf.c (SHT_NULL, SHT_SYMTAB, SHT_RELA, SHT_REL, SHT_GROUP): Add various sectopn header types. (SHF_EXCLUDE): Add flag. (Elf32_External_Sym, Elf64_External_Sym): Add symbol struct. (ELF_ST_BIND, ELF_ST_TYPE, ELF_ST_INFO): Add accessors. (STT_OBJECT, STT_FUNC, STT_TLS, STT_GNU_IFUNC): Add Symbol types. (STV_DEFAULT): Add symbol visibility. (SHN_COMMON): Add special section index name. (struct simple_object_elf_write): New. (simple_object_elf_start_write): Adjust for new private data. (simple_object_elf_write_shdr): Pass in values for all fields we write. (simple_object_elf_write_to_file): Adjust. Copy from recorded section headers if requested. (simple_object_elf_release_write): Release private data. (simple_object_elf_copy_lto_debug_sections): Copy and rename sections as denoted by PFN and all their dependences, symbols and relocations to the empty destination file. (simple_object_elf_functions): Adjust for copy_lto_debug_sections hook. * simple-object-xcoff.c (simple_object_xcoff_find_sections): Search symbol table for .go_export symbol and apply pfn if found. --- libiberty/simple-object-mach-o.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'libiberty/simple-object-mach-o.c') diff --git a/libiberty/simple-object-mach-o.c b/libiberty/simple-object-mach-o.c index bbadf5d8330..b90fca88b23 100644 --- a/libiberty/simple-object-mach-o.c +++ b/libiberty/simple-object-mach-o.c @@ -1374,5 +1374,6 @@ const struct simple_object_functions simple_object_mach_o_functions = simple_object_mach_o_release_attributes, simple_object_mach_o_start_write, simple_object_mach_o_write_to_file, - simple_object_mach_o_release_write + simple_object_mach_o_release_write, + NULL }; -- cgit v1.2.1
