> 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. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T12f163bbd73cfb63-Mc38b45eefa162e45c3a65ebe Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
