[Joeq-devel] *Address & Bootstrapping

[Alan R. <ala...@gm...>]

Hi John,

I've been making progress towards embedding a checkpointer into the image
created at bootstrap.  I am working along the lines of each native thread
being able to checkpoint itself.  Initially to get a prototype, I am using a
single native thread with a single threaded java app.

I am running into issues subclassing CodeAddress.  I have created a
RuntimeBootImage, all based on the SinglePass / Bootstrapper approach. I
call the checkpoint routine from a new jq_NativeThread method
<start_checkpointer()>.  However, this design requires that I create a
(based on BootstrapHeapAddress) CheckpointHeapAddress &
CheckpointCodeAddress object at runtime,  which I cannot do because they're
superclasses are not really objects.

Any suggestions on a way to work around this issue?

Thanks,
Alan
