To check teh FPU behavior of ORPSOC-de0-nano

I tried to run the or1200-float.c that is include in the tests folder.

after running or1200-float.c, we checked that the output was ok by report command.

but we found that FPU module is not working in HDL simulation

I think floating point operation is processed not by FPU but by floating point library

someone can help me how to operate FPU hardware for floating point processing please?

i use or32-elf-gcc (OpenRISC 32-bit toolchain for or32-elf (built 20110410)) 4.5.1-or32-1.0rc4

thanks
