Yup. Times out. This is because the branch delay slot scheduler is more than a
wee bit slow. This can finish on really fast hardware, or at least should. Also,
you can run it by hand to verify that it passes.

(for the record, this is in no way new.  I've remembered this since i
started testing gcc against mips-sim.)

It also times out on low-end x86 hardware, so the branch delay slot scheduler is
certainly not the only culprit. On the contrary, it passes for the 3.3 branch
(and the 3.2 branch) on the same hardware.

Fair enough. I looked into it at one point on mips and it was spending
~75% of it's time in dbr_sched

All gcc.c-torture/compile/20001226-1.c tests now pass for me running on the same
host that had the initial failure.
