Detailed Description

template<typename IRUnitT, typename AnalysisManagerT = AnalysisManager<IRUnitT>, typename... ExtraArgTs>
class llvm::PassManager< IRUnitT, AnalysisManagerT, ExtraArgTs >

Manages a sequence of passes over a particular unit of IR.

A pass manager contains a sequence of passes to run over a particular unit of IR (e.g. Functions, Modules). It is itself a valid pass over that unit of IR, and when run over some given IR will run each of its contained passes in sequence. Pass managers are the primary and most basic building block of a pass pipeline.

When you run a pass manager, you provide an AnalysisManager<IRUnitT> argument. The pass manager will propagate that analysis manager to each pass it runs, and will call the analysis manager's invalidation routine with the PreservedAnalyses of each pass it runs.
