// 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
