	* config/i386/i386.c (init_cumulative_args): For -m32 -mfpmath=sse
	and local functions, set sse_nregs to 8 and float_in_sse.
	(function_arg_advance, function_arg): If float_in_sse, pass
	SFmode and DFmode arguments in SSE registers.
	* config/i386/i386.h (CUMULATIVE_ARGS): Add float_in_sse field.

	* config/i386/i386.c (ix86_value_regno): Only optimize local functions
	of -funit-at-a-time.

	* config/i386/i386-protos.h (ix86_function_value): Accept two
	arguments, like the target macro.
	* config/i386/i386.h (FUNCTION_VALUE): Pass both arguments.
	* config/i386/i386.c (ix86_function_value): Accept the second
	argument of the target macro.
	(ix86_function_ok_for_sibcall): Pass a function pointer to
	ix86_function_value.
	(ix86_function_value, ix86_libcall_value) [!TARGET_64BIT]: Adjust
	call to ix86_value_regno).
	(ix86_value_regno): Add support for returning floating point values
	in SSE registers.
