Member Function Documentation

getAnalysisUsage()

void ReachingDefInfoWrapperPass::getAnalysisUsage ( AnalysisUsage & AU ) const

overridevirtual

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 70 of file ReachingDefAnalysis.cpp.

releaseMemory()

void llvm::ReachingDefInfoWrapperPass::releaseMemory ( )

inlineoverridevirtual

releaseMemory() - This member can be implemented by a pass if it wants to be able to release its memory when it is no longer needed.

The default behavior of passes is to hold onto memory for the entire duration of their lifetime (which is the entire compile time). For pipelined passes, this is not a big deal because that memory gets recycled every time the pass is invoked on another program unit. For IP passes, it is more important to free memory when it is unused.

Optionally implement this function to release pass memory when it is no longer used.

Reimplemented from llvm::Pass.

Definition at line 349 of file ReachingDefAnalysis.h.

runOnMachineFunction()

bool ReachingDefInfoWrapperPass::runOnMachineFunction ( MachineFunction & MF )

overridevirtual

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

Implements llvm::MachineFunctionPass.
