This book constitutes the refereed proceedings of the 16th International Conference on Compiler Construction, CC 2007, held in Braga, Portugal, in March 2007 as part of ETAPS 2007, the European Joint Conferences on Theory and Practice of Software. The 15 revised full are organized in topical sections on architecture, garbage collection and program analysis, register allocation, and program analysis.
