regmove and regclasses


Hi,

I'm probably overlooking something trivial, but...  where does
regmove get its regclasses from?  It calls reg_preffered_class()
but that only makes sense after calling regclass(), and that
doesn't happen until register allocation.  So that would mean
that regmove always gets GENERAL_REGS from the calls it makes
to reg_preffered_class().  What's going on here?

Gr.
Steven
