// This header defines the pass manager interface for codegen. The codegen
// pipeline consists of only machine function passes. There is no container
// relationship between IR module/function and machine function in terms of pass
// manager organization. So there is no need for adaptor classes (for example
// ModuleToMachineFunctionAdaptor). Since invalidation could only happen among
// machine function passes, there is no proxy classes to handle cross-IR-unit
// invalidation. IR analysis results are provided for machine function passes by
// their respective analysis managers such as ModuleAnalysisManager and
// FunctionAnalysisManager.

// TODO: Add MachineFunctionProperties support.
