; This verifies that single-precision floating point values that can't
; be passed in registers are stored in the rightmost word of the parameter
; save area slot.  There are 13 architected floating-point registers, so
; the 14th is passed in storage.  The address of the 14th argument is
; 48 (fixed size of the linkage area) + 13 * 8 (first 13 args) + 4
; (offset to second word) = 156.
