I would say it means to have a "stackless" code generator. You may want
to see http://en.wikipedia.org/wiki/Spaghetti_stack and
http://www.nondot.org/sabre/LLVMNotes/ExplicitlyManagedStackFrames.txt .

"Stackless" means that you do not use the "system" stack, but that
rather, your language frontend manages the stack frames itself.

Hope this is any help,
