--- Comment #8 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
(In reply to Jacob Lifshay from comment #7)
> turns out the fpow instruction isn't super high priority for 3D, the
> following is sufficient:
> pow(b, x) = exp2(x * log2(b))

... and bit-level accuracy isn't absolute (or is it? what's the
Khronos Group ULP for fpow?)

> I also did some misc cleanups and implemented recursive [[!inline]] support
> (which it turns out we need since ls010 uses svp64/appendix which in turn
> uses preduce.py)
