◆ getAnalysisUsage()

void MachinePostDominatorTree::getAnalysisUsage ( AnalysisUsage & AU ) const

getAnalysisUsage - Subclasses that override getAnalysisUsage must call this.

For MachineFunctionPasses, calling AU.preservesCFG() indicates that the pass does not modify the MachineBasicBlock CFG.

◆ print()

void MachinePostDominatorTree::print	(	llvm::raw_ostream &	OS,
		const Module *	M = `nullptr`
	)		const

overridevirtual

print - Print out the internal state of the pass.

This is called by Analyze to print out the contents of an analysis. Otherwise it is not necessary to implement this method. Beware that the module pointer MAY be null. This automatically forwards to a virtual function that does not provide the Module* in case the analysis doesn't need it it can just be ignored.

Reimplemented from llvm::Pass.
