PR 24907 binutils* objdump.c (null_print): New function. (disassemble_bytes): Delete previous_octets local and replace with a test of the max_reloc_offset_into_insn field of the bfd_arch_info structure. If a reloc is a potential match for the next insn, then perform a dummy disassembly in order to calculate its real length. bfd * archures.c (bfd_arch_info_type): Add max_reloc_offset_into_insn field.
