> Deoptimization and uncommon trap stubs require last Java PC to point to a PC which has an appropriate OopMap. Otherwise, -XX:+VerifyStack does no longer work after [JDK-8284161](https://bugs.openjdk.org/browse/JDK-8284161).
> I had to debug through the frame stuff and I made the code a bit more robust and easier to use and debug.
Martin Doerr has updated the pull request incrementally with one additional commit since the last revision:
frame::sender_for_compiled_frame: Put sender_sp and _pc into local variables as needed for the Loom port.
