Member Function Documentation

void PEI::getAnalysisUsage ( AnalysisUsage &  AU ) const

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::MachineFunctionPass.

Definition at line 66 of file PrologEpilogInserter.cpp.

References llvm::MachineFunctionPass::getAnalysisUsage().

bool PEI::runOnMachineFunction ( MachineFunction &  Fn )

virtual

runOnMachineFunction - Insert prolog/epilog code and replace abstract frame indexes with appropriate references.

Implements llvm::MachineFunctionPass.
