Base Classes

Name	Description
`FunctionPass`	FunctionPass class - This class is used to implement most global optimizations. Optimizations should subclass this class if they meet the following constraints:
`PMDataManager`	PMDataManager provides the common place to manage the analysis data used by pass managers.
