Detailed Description
BasicBlockPass class - This class is used to implement most local optimizations. Optimizations should subclass this class if they meet the following constraints: 1. Optimizations are local, operating on either a basic block or instruction at a time. 2. Optimizations do not modify the CFG of the contained function, or any other basic block in the function. 3. Optimizations conform to all of the constraints of FunctionPasses.
