Common Sub Expression optimization is done as part of optimization level
2. Register coloring is done in level 1. The various optimizations that
are done are discussed in the IDE User Guide on pages 361-365.
Individual optimizations can be turned on/off without using the slider,
as well. See the pragma section of the C Compilers manual.
