Local optimizations
John T. Bagwell · ACM SIGPLAN Notices · 1970
Some local optimizations (as opposed to global optimizations} are presented and a suitable one-pass compiler design for using them is shown. Optimizations shown are divided into machine dependent and independent classes with examples of each. There is some discussion of a subscript calculation technique which is an improvement over the usual technique, and a discussion of the best way to raise a quantity to a known small constant power by inline code. Various register allocation criteria are mentioned.
