- // This file implements 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
