Hi all!

Recently there has been lots of fuzz about using the different
hardware acceleration options available on the N800 (DSP, FPU and the
PowerVR chip) with various success levels. The PowerVR chip seems to
be completely out-of-reach (barring a miracle), the DSP is used by
selected amount of Nokia-provided gst plugins and some other stuff but
so far no real 3rd party success on using it (AFAIK?).

So, that leaves the FPU. Fortunately using that is much easier and
simply a question of setting compiler options and rebuilding.

So me and Tuomas Kulve decided to do some testing on compiling stuff
with support for the VFP and blogged about the results:



I make some bold guesses on the reasons for what happens, though I'm
not really expert on the low-level stuff. Any corrections or insights
are warmly welcomed.
