binutils-gdb/bfd/cpu-msp430.c
Nick Clifton aebcfb76fc Enhance the disassembler so that it will reliably determine whether a reloc applies to the middle of the next insn.
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.
	(bfd_default_arch_struct): Initialise the new field.
