My work on the s390 port of CACAO was finished around the beginning of summer 2007. Our criteria for the port to be finished were:

• Passing all benchmarks of the dacapo benchmark suite.
• Passing the mauve test suite. This turned out to be useful as some tests have still located bugs.

As the work was part of an internship, i had to document it. This took some time in the summer 2007. The documentation was finished around the beginning of fall 2007 and checked as part of the CACAO Handbook into the mercurial repository in docs/s390.tex.

The internship finished, time has come to start working on a master’s thesis. I’ve got 2 subjects to choose from: implement escape analysis for the optimizing compiler or rework the framework of the optimizing compiler. After taking one month to have a look at both subjects, I have chosen to work on escape analysis.
