* config/tc-m68hc11.h (md_relax_frag): Define to support relaxations that are not pc-relative. (m68hc11_relax_frag): Declare. * config/tc-m68hc11.c (build_indexed_byte): Use a frag_var to handle the offsetable indexed addressing modes (n,r). (build_insn): Cleanup some locals. (m68hc11_relax_frag): New function imported from tc-cris.c to handle relaxation of difference between two symbols of same section. (md_convert_frag): For INDEXED_OFFSET relaxs, use the displacement only when this is a PC-relative operand and the offset is not absolute. (md_estimate_size_before_relax): Convert the INDEXED_OFFSET,UNDEF frag to INDEXED_OFFSET,STATE_BITS5 when the symbol is absolute; this will be handled by m68hc11_relax_frag.
