--- Comment #1 from Luke Kenneth Casson Leighton <lkcl@lkcl.net> ---
register allocations, for fu.div.pipe_data.py
looks to be identical to ALUInputData and ALUOutputData.
https://libre-soc.org/openpower/isa/fixedarith/
# Divide
XO-Form divw* RT,RA,RB
Special Registers Altered:
* CR0 (bits 0:2 undefined in 64-bit mode) (if Rc=1)
* SO OV OV32 (if OE=1)
# Modulo
X-Form mod* RT,RA,RB
no special regs altered
