(tc_m68hc11_force_relocation): Declare. * config/tc-m68hc11.c (md_pseudo_table): Add relax command. (s_m68hc11_relax): New function for relax group. (build_insn, build_jump_insn): Emit a M68HC11_RL_JUMP reloc at beginning of jump instruction. (md_pcrel_from): Rename from md_pcrel_from_section and fix address computation. (tc-gen_reloc): Update. (md_estimate_size_before_relax): Create the BFD_RELOC_16_PCREL as PC-relative fixup. (tc_m68hc11_force_relocation): New function, handle new relocs. (tc_m68hc11_fix_adjustable): New to make sure there are enough reloc for the linker relax pass. (md_apply_fix3): Handle M68HC11_RL_JUMP, M68HC11_RL_GROUP and VTABLE relocs.
