But yeah, the VM stub only handles moves, and I think we want to keep it that way (for reasons outlined). The VM stub can be viewed as a low-level primitive that accepts a set of register/stack values, and moves them into the corresponding locations. It's not really supposed to be doing any kind of processing of the values it receives or returns. ------------- PR: https://git.openjdk.org/jdk/pull/12708
