Code-Generation Technique for Large-Language Compilers

The design of an optimizing compiler for a large and rich language poses problems beyond those of sheer size and cost. One of the most serious is that the wealth and variety of the language makes it possible to express the same logical function in terms of many different source constructs. The choice may be based on naturalness of language use, program readability, ease of debugging, compiletime or object-time space-versus-time tradeoffs, or programmer whimsicality.
