* m68k-tdep.h (enum m68k_flavour): New.
(struct gdbarch_tdep): New fields float_return, flavour and fpregs_present. * m68k-tdep.c (m68k_register_type): Use fpregs_present and conditionalize floating registers type on flavour. (m68k_register_names): New. (m68k_register_name): Use the above. (m68k_convert_register_p): Consult fpregs_present. (m68k_register_to_value, m68k_value_to_register): Use register_type to obtain the type of floating point registers. (m68k_svr4_extract_return_value): Check tdep->float_return. Use register_type to get the type of floating point regiters. (m68k_svr4_store_return_value): Likewise. (m68k_dwarf_reg_to_regnum): Check tdep->fpregs_present. (m68k_analyze_register_saves): Likewise. (m68k_gdbarch_init): Extract infromation from XML description, if present. Guess coldfire by looking at the file, if present. Conditionalize setting of long double format. Set decr_pc_after_break to 2 on coldfire and fido. Enable XML-driven register description. * m68kbsd-tdep.c (m68kbsd_fpreg_offset): Use size of tdep->fpreg_type, as opposed to hardcoded value. * Makefile.in (m68k-tdep.o): Update dependencies.
