Re: along the way...

> is it worth using vfp when neon is around?

Plan 9 arm source uses "vfp" as a generic term to mean modern
hardware floating point instruction set (as opposed to the old
arm7500 instruction set, which I suspect has always been purely
emulated since processors implementing this set were quite rare).
No use has been made in Plan 9 (as far as I know) of the vector
extensions which are the "v" part of vfp.

I think the neon instruction set is a superset of the vfp set
which 5l generates, so using vfp doesn't preclude something
like a vector library with neon support.
