Hello, everyone!


I have trouble with MPC8572DS board. I make bareboard application (.elf). I use powerpc-linux-gnu compiler. Trouble is with floating-point instructions. In my bareboard application i use unsigned long long numbers and compiler makes

lfd f0,16(r31)


instructions wich write in floating-point registers but MPC8572DS havent floating-point registers. I know about MSR[SPE] bit.


What compiler flags or compiler i need to use to avoid this error.
