that is there is no code with `fpscr |= FP_FR`,

I've seen nothing in fpu_helper.c to update
the fpscr to FP_FR,
that is there is no code with `fpscr |= FP_FR`,

Hi,
Your series seems to have some coding style problems. See output below for
more information:

floating point unit

- Different hosts produced different results and instead wanted consistency?
This is the correct answer. Ther
