Congrats Andy -- you've solved the "gcc won't inline" problem !
I recalled last night that I'd seen similar bad init complaints from crafty when
I had previously tried -fast as an option -- so I removed it, going back to my
"ugly" explicit option list ... and the problem disappeared -- moreover, bench
speed looks good too! You should make a separate "crafty bench" post to give
the results to the group. :-)
I'm expecting the 2.5GHz to break 3.1Mnps on crafty bench -- when the local
Apple store gets one in I'll try to bench crafty there.
