Before I try my hand at an FPU,

Some questions:
 - Do we have any FPU attempt in nMigen, Verilog, or some other language yet that I should be aware of?
 - The POWER ISA 3.0 PDF doc specifies an IEEE 745-1985 compliant mode as well as a faster non-compliant mode - I’m guessing we have to implement both?
 - I imagine your RUST algebraics library should be useful for this?
 - how many stages should I have for the FPU - is there a sweetspot?
 - We’re doing a reconfigureable FPU correct? What bit modes does it support?
