and Christian correctly if I'm wrong but it only forces inlining when the JIT is triggered. So using the annotation on something which is not called enough will do nothing. As I said in an earlier mail, the golden hammer is the annotation PleaseJITThisCodeWithAPrivateMetaDataObjectNowAndReJITLaterWhenTheMethodOrTheLoopIsHot > > -- Chris Rémi _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
