Detailed Description

MachineFunctionPassManager adds/removes below features to/from the base PassManager template instantiation.

Support passes that implement doInitialization/doFinalization. This is for machine function passes to work on module level constructs. One such pass is AsmPrinter.
Support machine module pass which runs over the module (for example, MachineOutliner). A machine module pass needs to define the method:

Error run(Module &, MachineFunctionAnalysisManager &)

FIXME: machine module passes still need to define the usual machine function pass interface, namely, PreservedAnalyses run(MachineFunction &, MachineFunctionAnalysisManager &) But this interface wouldn't be executed. It is just a placeholder to satisfy the pass manager type-erased inteface. This special-casing of machine module pass is due to its limited use cases and the unnecessary complexity it may bring to the machine pass manager.
The base class run method is replaced by an alternative run method. See details below.
Support codegening in the SCC order. Users include interprocedural register allocation (IPRA).

◆ run()

Error llvm::MachineFunctionPassManager::run	(	Module &	M,
		MachineFunctionAnalysisManager &	MFAM
	)

Run machine passes for a Module.

The intended use is to start the codegen pipeline for a Module. The base class's run method is deliberately hidden by this due to the observation that we don't yet have the use cases of compositing two instances of machine pass managers, or compositing machine pass managers with other types of pass managers.
