STM32F4 Keil ARM FPU interrupts

I want to use the STM32F4 floating point hardware FPU in my main code and in interrupt service routines. Apart from telling the compiler I'm using the FPU, do I need to do anything extra to save and restore FPU registers and status in interrupt service routines (to prevent interrupted FPU operations from being corrupted)? I assume the compiler takes care of it for me.

I have looked on the Keil website and couldn't find a clear explanation. Anybody know please?
