FPU float in functions calls

After taking a look to the STM32F4 documentation redface, I can confirm that the FPU only supports float variables in simple precision. That explains the slowdown with double variables I had before. rolleyes. But what can explain the fact that it is impossible to use float vaiables as parameters in a function call ?
