Member Function Documentation

◆ getAnalysisUsage()

void MachinePostDominatorTreeWrapperPass::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.

◆ print()

void MachinePostDominatorTreeWrapperPass::print ( llvm::raw_ostream OS,
const Module M = nullptr 
) const
overridevirtual

print - Print out the internal state of the pass.

This is called by Analyze to print out the contents of an analysis. Otherwise it is not necessary to implement this method. Beware that the module pointer MAY be null. This automatically forwards to a virtual function that does not provide the Module* in case the analysis doesn't need it it can just be ignored.

Reimplemented from llvm::Pass.

Definition at line 117 of file MachinePostDominators.cpp.

◆ releaseMemory()

void llvm::MachinePostDominatorTreeWrapperPass::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 103 of file MachinePostDominators.h.

◆ runOnMachineFunction()

bool MachinePostDominatorTreeWrapperPass::runOnMachineFunction ( MachineFunction MF)
overridevirtual

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

Implements llvm::MachineFunctionPass.

◆ verifyAnalysis()

void MachinePostDominatorTreeWrapperPass::verifyAnalysis ( ) const
overridevirtual

verifyAnalysis() - This member can be implemented by a analysis pass to check state of analysis information.

Reimplemented from llvm::Pass.
