Some evidence to support...I modified the benchmark to pass all previously recursive calls through an intermediate function. Since it's fixed-arity with no block, it should directly bind through indy just fine. Perf improves by 2x! That's not enough to bring it back to the non-ruby-inlining setup, but perhaps it demonstrates that there's an issue with recursive inlining (for a start). https://gist.github.com/837095 - Charlie _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
