A good compiler contains a microcosm of computer science. It makes practi-
cal use of greedy algorithms (register allocation), heuristic search techniques
(list scheduling), graph algorithms (dead-code elimination), dynamic pro-
gramming (instruction selection), finite automata and push-down automata
(scanning and parsing), and fixed-point algorithms (data-flow analysis). It
deals with problems such as dynamic allocation, synchronization, nam-
ing, locality, memory hierarchy management, and pipeline scheduling.
