* config/m68k/m68k.c (m68k_handle_option): Handle OPT_mcfv4e.
(m68k_compute_frame_layout): Include space for ColdFire FPU regs.
(m68k_output_function_prologue): Save ColdFire FPU registers.
(m68k_output_function_epilogue): Restore ColdFire FPU registers.
(force_mode, fp_reg_operand, emit_move_sequence): New functions.
(m68k_regno_mode_ok): Don't allow types larget than 8 bytes in
ColdFire FPU registers.
(m68k_libcall_value, m68k_function_value): New functions.
* config/m68k/netbsd-elf.h (FUNCTION_VALUE): Use m68k_function_value.
(LIBCALL_VALUE): Use m68k_libcall_value.
* config/m68k/m68k.h (TARGET_CPU_CPP_BUILTINS): Define __mcfv4e__.
(MASK_COLDFIRE): Add MASK_CFV4E.
(TARGET_COLDFIRE_FPU, TARGET_HARD_FLOAT, TARGET_FP_REG_SIZE): New.
