Commit 2bf2bf23 exposed a bug on targets that create common sections other than the standard ELF SHN_COMMON. If these are output by ld -r, then their type becomes SHT_PROGBITS unless the target handles them specially (eg. by elf_backend_special_sections), and if they are merged into .bss/.sbss by ld -r then that section becomes SHT_PROGBITS. Worse, if they are output by ld -r, then their size is increased by bfd_generic_define_common_symbol during final link, which leads to bogus file contents being copied to output. For mips, it seems to me that the .scommon section should not be output for ld -r, but I haven't made that change in this patch. PR 24015 * elf.c (bfd_elf_get_default_section_type): Make common sections SHT_NOBITS. * linker.c (bfd_generic_define_common_symbol): Clear SEC_HAS_CONTENTS.
