SSA in GCC

NaturalBridge is currently participating in the development and integration of new static single assignment (SSA) optimizations into the Gnu Compiler Collection (GCC). GCC is an open source compiler that has been in use since the early 1990's. It is used as the system compiler by virtually all Unix implementations as well as many embedded applications. However, the GCC was the last big compiler without SSA optimizations. We have been supporting the retrofitting of SSA into this compiler. Our role has been to identify problems with the current optimization architecture as well as to design and implement new optimization algorithms.
