Detailed Description

MachineFunctionPass - This class adapts the FunctionPass interface to allow convenient creation of passes that operate on the MachineFunction representation. Instead of overriding runOnFunction, subclasses override runOnMachineFunction.

void MachineFunctionPass::getAnalysisUsage

(

AnalysisUsage &

AU

)

const [override, protected, virtual]

getAnalysisUsage - Subclasses that override getAnalysisUsage must call this.

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

Reimplemented from llvm::Pass.

Reimplemented in llvm::SlotIndexes, llvm::LiveIntervals, llvm::LiveVariables, llvm::AsmPrinter, llvm::MachineDominatorTree, llvm::MachineLoopInfo, llvm::MachineRegionInfoPass, llvm::MachineDominanceFrontier, llvm::LiveStacks, llvm::MachinePostDominatorTree, llvm::MachineTraceMetrics, llvm::VirtRegMap, llvm::SelectionDAGISel, llvm::StackMapLiveness, llvm::MachineBlockFrequencyInfo, and llvm::PEI.
