So, I was looking at the PICOBIT papers. I noted that the representation of continuations has a "parent" field. Presumably this is to allow something like "continuation-next" from the Better API for First Class Continuations paper.
However, I don't see any corresponding virtual machine instructions to manipulate continuations.
At that point, I presumed that some form of CPS conversion was going on that was wiping out continuations, so I looked at the 90 Minute Scheme to C compiler stuff. Unfortunately, I don't see how to get "continuation-next" in the context of purely CPS conversion.
Anybody have suggestions as to what I am missing and where to look?
Obviously, I can look through the full PICOBIT source, but doing so without some landmarks is suboptimal.
Thanks, -a
