Hi,

while looking at this some more I came to the following
questions/assumptions, so I'd be grateful if you could shortly address them:

-While implementing our own kernel last semester me and my team-mate came
to believe that pusha/popa were faster that pushing/popping the individual
registers, since it is just a single command. The Mini-OS kernel however
does the latter. Is that a conscience performance-trade for something or
did we just underly a misconception, in that it compiles to the same thing
in the end?

-Lazy floating point register saving is similar to Copy-on-write, is that
correct?

-There is nothing preventing me from using some floating-point library for
the user-space test program, right?

I'd also appreciate if you could have a quick glance my updated proposal
(on the GSoC portal) and give me some more feedback on it.

Thanks
Felix
