+       * elfxx-mips.c (ABI_O32_P, MIPS_ELF_ABIFLAGS_SECTION_NAME_P): New macro.
+       (mips_elf_obj_tdata): Add abiflags and abiflags_valid fields.
+       (bfd_mips_elf_swap_abiflags_v0_in): New function.
+       (bfd_mips_elf_swap_abiflags_v0_out): Likewise.
+       (_bfd_mips_elf_section_from_shdr): Handle SHT_MIPS_ABIFLAGS.
+       (_bfd_mips_elf_fake_sections): Likewise.
+       (_bfd_mips_elf_always_size_sections): Handle .MIPS.abiflags.
+       (_bfd_mips_elf_additional_program_headers): Account for new
+       PT_MIPS_ABIFLAGS program header.
+       (_bfd_mips_elf_modify_segment_map): Create PT_MIPS_ABIFLAGS segment and
+       associate with .MIPS.abiflags.
+       (_bfd_mips_elf_gc_mark_extra_sections): New function.
