	* config/rs6000/rs6000.c (rs6000_function_arg): If a float argument
	does not fit fully into floating-point registers, and there is still
	space in the register parameter area, use GPRs to pass those parts
	of the argument.  Issue -Wpsabi note if any parameter is now treated
	differently than before.
	(rs6000_arg_partial_bytes): Update.

	* gcc.target/powerpc/ppc64-abi-warn-1.c: New test.
