Please let me know once you do have something.
I would like to consider reducing inline limits somewhat again the
current setting of 500 has been intentionally set a bit up as I wanted
to see responses from people complaining about too little/too much
inlining.  It looks like no one is complailing about too little inlining
and Gerald's testcase would always benefiting from setting it bit less.
Also SPEC performance has suffered somewhat from this change on Athlons
with relatively small cache, so it seems to me that 250 would be good
value.  It may be very nice to benchmark it on SPECs with intermodule
inlining so we see more.
Given that the mainline is in stage3 I think I should do more tests
soon.
