Previously, compiler transformations have primarily focused on
minimizing program execution time. This thesis explores some examples
of applying compiler technology outside of its original scope.
Specifically, we apply compiler analysis to the field of software
maintenance and evolution by examining the use of global data
throughout the lifetimes of many open source projects. Also, we
investigate the effects of compiler optimizations on the power
consumption of small battery powered devices. Finally, in an area
closer to traditional compiler research we examine automatic program
parallelization in the form of thread-level speculation
