	* config/s390/s390.c (s390_handle_arch_option): New architecture
	switch: z9-ec.
	(override_options): Sanity checks for the new options added.
	* config.gcc: New architecture switch: z9-ec.
	* config/s390/s390.h (processor_flags): PF_DFP added.

	(TARGET_DEFAULT): Due to the s390.opt changes hard float is enabled
