This book constitutes the proceedings of the 23rd International Conference on Compiler Construction, CC 2014, which was held as part of the European Joint Conferences on Theory and Practice of Software, ETAPS 2014, which took place in Grenoble, France, in April 2014. The 10 full papers and 4 tool papers included in this volume were carefully reviewed and selected from 47 submissions; the book also contains one invited talk. The papers are organized in topical sections named: program analysis and optimization; parallelism and parsing and new trends in compilation.
