It might well work for collecting stats on fast path cases (I'll try it with our micro-benchmarks), but I doubt it will produce useful output once the site has gone to the slower megamorphic version - plus by instrumenting our sites I could collect stats on SwitchPoint invalidations per site and cache access patterns in the megamorphic case both of which were rather useful. _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
