Ivan, I'm absolutely agree with you that support of different types of
native calls from Java is the same task as calling slow native methods from
a fast-path helper.
This task worth a separate discussion because it has multiple notable
solutions.
As for today I prefer to finish JIT framework for helpers inlining first and
report that it's ready with a minimum of new features. (I'm going prototype
native call as Weldon proposed, so we refactor this part once we have an
agreement on final design)
+ Is it ok if I remove cleaning code from the helper to avoid memset? I
could replace it with a loop, but imo it's too much for a helper's fast
path.. ?
Yes, remove it.
