A/UX doesn't even come close to booting yet with the new FPU,
but we're getting there. I don't want to trash master with
a code base that doesn't work. Also, I turned off ethernet
in the cocoa GUI, since the TAP driver isn't working right
on 10.10 yet.
- the framework for throwing exceptions should work correctly now
- NaNs and signaling NaNs should work
- condition codes are set now
- write-back and rounding (including throwing INEX2) are now implemented
(Note: you can't actually use any of this code yet, and it doesn't actually
fully implement any fmath_* instructions yet)
Once the framework for handling exceptions, accrued exceptions,
condition codes, and rounding is done, I can start implementing
actual "fmath" instructions. Everything not handled by softfloat
will be imprecisely and hackily implemented by using the best
available native float math (e.g. cosf(), cos(), or cosl())
