Current SSA Optimizations
CCP (sparse Conditional Constant Propagation).
DCE (Dead Code Elimination).
PRE (Partial Redundancy Elimination) with strength reduction.
Dominator-based optimizations such as copy propagation, constant propagation and redundancy elimination using value numbering
Must-alias analysis, to convert pointer de-references into regular variable references whenever possible
Scalar Replacement of Aggregates, to convert structure references into scalar references that can be optimized using the standard scalar passes
