Questions about MQXCFG_ENABLE_FP, and MQX floating point

If I enable floating point hardware in my compiler (in this case Keil uv5) is it mandatory that I enable MQXCFG_ENABLE_FP in my BSP assuming my code does not use any floating point?  Conversely, if I don't enable floating point hardware in my compiler, is there an impact with enabling MQXCFG_ENABLE_FP?


Does RTCS/MQX/Shell source use floating point (math or C-operators)?  Or are any of these guaranteed floating point free by design?


Does MQX task model implement lazy stacking per this application note, for processors that support it?
