Thanks for pointing that out, Mark. As the JEP notes, Vladimir Ivanov is working on a number of approaches for LF reduction. Caching similarly-shaped instances is relatively straightforward, although changing from our "full custom" approach is difficult. The tricky part is to split just enough to avoid polluted profiles, especially the hot GWT nodes. For the curious, some patches in progress may be found here: http://cr.openjdk.java.net/~vlivanov/lfc/
Independently, Duncan McGregor has found some replicated DMHs that can be cache. In the long term, our work in Valhalla to build frameworks for specializing code (shrinking Object refs to primitives and value types) should be applicable to method handles. — John On Aug 19, 2014, at 12:30 PM, Mark Roos <mr...@roos.com> wrote: > Related to the overhead of Lambda forms from Mark Reinhold on the Hotspot > list. > Looks like some efforts to improve them. > > New JEP Candidate: http://openjdk.java.net/jeps/210 _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
