It was brought to my attention late yesterday afternoon (Tuesday, 25 June) that
I left out an important part of the specification for fork: the child's
registers contain copies of the parent's register contents. Both the tree and
forkjoin batch disks require this behavior and won't work for systems that
don't provide it.
I've updated the assignment 1 page to include the missing spec for fork. I've
also rewritten the tree and forkjoin disks to not check for register passing,
and regraded your first assignments using the revised disks.
Your operating system needs to implement register passing on forks; the batch
disks in the class directory have not been revised and depend on register
passing. I've just regraded your assignments after removing any tests for
register passing.
My apologies for all the problems this has caused. This class is hard enough
without me making it impossible by forgetting to specify important os behavior.
