GCC aggregate trackinga project by jamborm Currently GCC relies only on the most generic alias analysis when attempting to track data in aggregates in interprocedural (IPA) optimizations. In the course of this project I plan to revive patches for using simple escape analysis to track all data which do not have their address escaped and use that information to track constants within them, analyze the impact on a number of benchmarks and submit them to GCC trunk.

GCC Performance/Regression Dashboarda project by marxin For development purpose, it is very useful to have an infrastructure that can spot regressions based on commit base. Currently, our existing infrastructure runs mainly SPEC benchmark and is cumbersome from perspective of any further development. I would like to build a replacement that will combine buildbot framework with a custom web project (based on Django framework). The web project will be used both for submitting reports coming from a buildbot slave and for UI which will serve plots and data.
