Right, in fact currently GCJ does no inlining at all. Inlining will 
certainly improve performance significantly (depending on the 
application) if it is done well.

-finline-functions can still be used to turn on the old inliner. That 
code is not smart and will miss many inline opportunities, but it might 
still be interesting to see if it makes a difference to your application.
