-Wstringop-truncation warnings
This patch is aimed at silencing gcc8 -Wstringop-truncation warnings. Unfortunately adding __attribute__ ((__nonstring)) doesn't work in a number of the places patched here, (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85643) so if you have recent glibc headers installed you'll need to configure binutils with --disable-werror to compile using gcc8 or gcc9. include/ * ansidecl.h: Import from gcc. * coff/internal.h (struct internal_scnhdr): Add ATTRIBUTE_NONSTRING to s_name. (struct internal_syment): Add ATTRIBUTE_NONSTRING to _n_name. bfd/ * elf-linux-core.h (struct elf_external_linux_prpsinfo32_ugid32), (struct elf_external_linux_prpsinfo32_ugid16), (struct elf_external_linux_prpsinfo64_ugid32), (struct elf_external_linux_prpsinfo64_ugid16): Add ATTRIBUTE_NONSTRING to pr_fname and pr_psargs fields. Remove GCC diagnostic pragmas. Move comment to.. * elf.c (elfcore_write_prpsinfo): ..here. Indent nested preprocessor directives. * elf32-arm.c (elf32_arm_nabi_write_core_note): Add ATTRIBUTE_NONSTRING to data. * elf32-ppc.c (ppc_elf_write_core_note): Likewise. * elf32-s390.c (elf_s390_write_core_note): Likewise. * elf64-s390.c (elf_s390_write_core_note): Likewise. * elfxx-aarch64.c (_bfd_aarch64_elf_write_core_note): Likewise. * elf64-x86-64.c (elf_x86_64_write_core_note): Add GCC diagnostic pragmas. * peXXigen.c (_bfd_XXi_swap_scnhdr_out): Use strnlen to avoid false positive gcc-8 warning. gas/ * config/obj-evax.c (shorten_identifier): Use memcpy in place of strncpy. * config/obj-macho.c (obj_mach_o_make_or_get_sect): Ensure segname and sectname fields are NUL terminated.
