Hi Aleksey, I don't think TraceTypeProfile works in this case.
First, only invokevirtual and invokeinterface actually have type profiles; other invokes don't. You can see that from the interpreter code that only invokevirtual and invokeinterface do profile_virtual_call() (which keeps track of the invocation count plus receiver types), whereas other invokes do profile_call() (only keeps the invocation count). Second, even if invokedynamic had a type profile, by default it'd only keep track of 2 receiver types, which is not enough for Duncan's case. - Kris On 11/30/2012 03:34 AM, Aleksey Shipilev wrote: > On 11/29/2012 11:15 PM, MacGregor, Duncan (GE Energy Management) wrote: >> Thanks for any help you can give., > Probably unrelated, but can't you do the same thing by dumping the type > profile from HotSpot? -XX:+TraceTypeProfile (I think it requires debug > build at this point, but 7u12 onwards should have that available in > production builds). > > -Aleksey. > _______________________________________________ > mlvm-dev mailing list > mlvm-dev@openjdk.java.net > http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
