   Hi, Dan.  I'll look at the 1st insn scheduling (the 2nd insn scheduling is
   actually faster) today.  As David, I suspect the code is slower because
   scheduling lookahead.  I think that the specific features of code is in long
   ready queues.  I have some ideas how to improve such behavior.

Vlad, remember yet another issue with applies to Sparc with
DFA.  The fact that we have DFA for many processor types and
state machine must make all of these processor type checks on
each state machine transition to see which DFA machines apply.

Or did you fix this?

It is real problem if it is not cured already.  Ix86 will hit it
too, as will MIPS when/if it gets DFA descriptions.
