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.

Member Function Documentation

void MachineFunctionPass::getAnalysisUsage ( AnalysisUsage &  AU ) const

protectedvirtual

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::LiveVariables, llvm::LiveIntervals, llvm::AsmPrinter, llvm::MachineLoopInfo, llvm::LiveStacks, llvm::MachinePostDominatorTree, llvm::MachineTraceMetrics, llvm::VirtRegMap, llvm::SelectionDAGISel, llvm::MachineDominatorTree, llvm::MachineBlockFrequencyInfo, and llvm::PEI.

runOnMachineFunction - This method must be overloaded to perform the desired machine code transformation or analysis.
