Creating a phase does any long 0N/A// running analysis required, and caches the analysis in internal data 0N/A// structures. Later the analysis is queried using transform() calls to 0N/A// guide transforming the program. When the Phase is deleted, so is any 0N/A// cached analysis info. This basic Phase class mostly contains timing and 0N/A// memory management code. 0N/A GVN,
