ChangeLog:
----------

	* NEWS: Add information on calling convention and new SH CLI options.

	* sh-tdep.c (sh_cc_gcc): New static string.
	(sh_cc_renesas): Ditto.
	(sh_cc_enum): New static string array.
	(sh_active_calling_convention): New static string pointer denoting
	active user chosen ABI.
	(sh_is_renesas_calling_convention): New function to return function
	specific ABI, or user choice if necessary.
	(sh_use_struct_convention): Rename first argument and turn around its
	meaning.  Check for renesas ABI and return accordingly.
	(sh_use_struct_convention_nofpu): New function.
	(sh_next_flt_argreg): Get function type as third parameter.  Check
	for renesas ABI and choose floating registers accordingly.
	(sh_push_dummy_call_fpu): Check for ABI and choose argument slot and
	struct return slot accordingly.
	(sh_push_dummy_call_nofpu): Ditto.
	(sh_return_value_nofpu): Call sh_use_struct_convention_nofpu from here.
	Evaluate ABI and give to sh_use_struct_convention_nofpu.
