This book constitutes the refereed proceedings of the 11th International Conference on Compiler Construction, CC 2002, held in Grenoble, France, in April 2002. The 19 revised full papers presented together with three tool demonstration papers and an invited paper were carefully reviewed and selected from 44 submissions. The papers are organized in topical sections on analysis and optimization, low-level analysis, grammars and parsing, domain-specific languages and tools, energy consumption optimizations, and loop and array optimizations.
