ABSTRACT:
Segments of memory are allocated to a stack cache as needed to accommodate additional continuation frames during execution of a program. When a continuation is captured, flags in all segments of the stack cache are set to indicate the signals are shared by a captured continuation, the top segment of the stack cache is copied, and the copy is made the top continuation frame of the stack cache. To invoke a continuation, the top segment of the invoked continuation is copied into the current stack cache segment. When the stack cache is ready to underflow into a segment shared by a captured continuation, the shared segment is copied and the stack cache underflows into the copy.
