Just to be clear, i'm looking at diego's em64t tester.

Our SPEC2000 performance on 252.eon dropped by a pretty large amount
between those days.

The only patch I see that could have affected this was:

+2006-09-01  Josh Conner  <jconner@apple.com>
+
+       PR c++/25505
+       * tree-nrv.c (dest_safe_for_nrv_p): New function.
+       (execute_return_slot_opt): Use it.

Josh, I assume you access to SPEC, so could you take a look at this?

(Sorry if i have pegged the wrong patch, i'm just going by the spec
tester diffs).
