hello first,
When I examined your dhrystone commands, I saw that there were float operations in the dhry1 file. I think you used float operation to prevent overflow but I'm running into problems while compiling. How did you prevent this? Or how will my processor perform the float operation when I use this? When I look at it, picorv32 does not have float operations either. Which is the important point here.

I generally deal with RTL design and I don't know much about compilers. I have struggled with this for a long time, but this problem cannot be solved without removing the float operation. I would be happy if you help.
