An automatic overlay generator

by R. Cytron, P. G. Loewner
We present an algorithm for automatically generating an overlay structure for a program, with the goal of reducing the primary storage requirements of that program. Subject to the constraints of intermodule dependences, the algorithm can either find a maximal overlay structure or find an overlay structure that, where possible, restricts the program to a specified amount of primary storage. Results are presented from applying this algorithm to three substantial programs.
