class MachineDominanceFrontier

Declaration

class MachineDominanceFrontier : public MachineFunctionPass { /* full declaration omitted */ };

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.

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:57

¶bool compare(
    DominanceFrontierBase<llvm::MachineBasicBlock,
                          false>& Other) const

Parameters

DominanceFrontierBase<llvm::MachineBasicBlock, false>& Other

¶bool compareDomSet(
    llvm::MachineDominanceFrontier::DomSetType&
        DS1,
    const llvm::MachineDominanceFrontier::
        DomSetType& DS2) const

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:93

Parameters

llvm::MachineDominanceFrontier::DomSetType& DS1

const llvm::MachineDominanceFrontier::DomSetType& DS2

¶llvm::MachineDominanceFrontier::iterator end()

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:61

¶llvm::MachineDominanceFrontier::const_iterator
end() const

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:65

¶llvm::MachineDominanceFrontier::iterator find(
    llvm::MachineBasicBlock* B)

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:69

Parameters

llvm::MachineBasicBlock* B

¶llvm::MachineDominanceFrontier::const_iterator
find(llvm::MachineBasicBlock* B) const

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:73

Parameters

llvm::MachineBasicBlock* B

¶void getAnalysisUsage(
    llvm::AnalysisUsage& AU) const

Description

getAnalysisUsage - Subclasses that override getAnalysisUsage must call this. For MachineFunctionPasses, calling AU.preservesCFG() indicates that the pass does not modify the MachineBasicBlock CFG.

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:105

Parameters

llvm::AnalysisUsage& AU

¶ForwardDominanceFrontierBase<
    llvm::MachineBasicBlock>&
getBase()

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:39

¶llvm::MachineBasicBlock* getRoot() const

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:45

¶const SmallVectorImpl<llvm::MachineBasicBlock*>&
getRoots() const

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:41

¶bool isPostDominator() const

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:49

¶void releaseMemory()

Description

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.

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:103

¶void removeBlock(llvm::MachineBasicBlock* BB)

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:81

¶void removeFromFrontier(
    llvm::MachineDominanceFrontier::iterator I,
    llvm::MachineBasicBlock* Node)

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:89

Parameters

llvm::MachineDominanceFrontier::iterator I

llvm::MachineBasicBlock* Node

¶bool runOnMachineFunction(
    llvm::MachineFunction& F)

Description

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

Declared at: llvm/include/llvm/CodeGen/MachineDominanceFrontier.h:101

Parameters

llvm::MachineFunction& F
