* elfxx-mips.c: Include libiberty.h. (elf_mips_isa, _bfd_mips_elf_mach_extends_p): Remove. (mips_set_isa_flags): New function, split out from... (_bfd_mips_elf_final_write_processing): ...here. Only call mips_set_isa_flags if the EF_MIPS_MACH bits are clear. (mips_mach_extensions): New array. (mips_32bit_flags_p): New function. (_bfd_mips_elf_merge_private_bfd_data): Rework architecture checks. Use mips_32bit_flags_p to check if one binary is 32-bit and the other is 64-bit. When adopting IBFD's architecture, adopt the bfd_mach as well as the flags. ld/testsuite/ * ld-mips-elf/jr.s: New file. * ld-mips-elf/mips-elf-flags.exp: New test.
