After many months of part time hacking on the ARM assembly for floating

submit the improvements I've done so far and move on to another

Nevertheless, the improvements in performance should be significant.
See for example this non-exhaustive instruction count comparison between
the old (current) and the new (with my patch) version of the lib which
should give a rough idea of the speed increase:
Cool! What testing have you done? Have you run any IEEE conformance
tests? Or, at least, the GCC DejaGNU tests?
Thanks,
