| // This pass implements interprocedural sparse conditional constant |
| // propagation and merging. |
| // |
| // Specifically, this: |
| // * Assumes values are constant unless proven otherwise |
| // * Assumes BasicBlocks are dead unless proven otherwise |
| // * Proves values to be constant, and replaces them with constants |
| // * Proves conditional branches to be unconditional |
