Member Function Documentation

void PEI::getAnalysisUsage

(

AnalysisUsage &

AU

)

const [override, 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 73 of file PrologEpilogInserter.cpp.

References llvm::MachineFunctionPass::getAnalysisUsage().

bool PEI::runOnMachineFunction

(

MachineFunction &

Fn

)

[override, virtual]

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

Implements llvm::MachineFunctionPass.
