Method Overview

• public OrderedInstructions(llvm::DominatorTree * DT)
• public bool dfsBefore(const llvm::Instruction *, const llvm::Instruction *) const
• public bool dominates(const llvm::Instruction *, const llvm::Instruction *) const
• public void invalidateBlock(const llvm::BasicBlock * BB)

Methods

¶OrderedInstructions(llvm::DominatorTree* DT)

Description

Constructor.

Declared at: llvm/include/llvm/Analysis/OrderedInstructions.h:44

Parameters

llvm::DominatorTree* DT

¶bool dfsBefore(const llvm::Instruction*,
               const llvm::Instruction*) const

Description

Return true if the first instruction comes before the second in the dominator tree DFS traversal if they are in different basic blocks, or if the first instruction comes before the second in the same basic block.

Declared at: llvm/include/llvm/Analysis/OrderedInstructions.h:53

Parameters

const llvm::Instruction*

const llvm::Instruction*

¶bool dominates(const llvm::Instruction*,
               const llvm::Instruction*) const

Description

Return true if first instruction dominates the second.

Declared at: llvm/include/llvm/Analysis/OrderedInstructions.h:47

Parameters

const llvm::Instruction*

const llvm::Instruction*

¶void invalidateBlock(const llvm::BasicBlock* BB)

Description

Invalidate the OrderedBasicBlock cache when its basic block changes. i.e. If an instruction is deleted or added to the basic block, the user should call this function to invalidate the OrderedBasicBlock cache for this basic block.

Declared at: llvm/include/llvm/Analysis/OrderedInstructions.h:59

Parameters

const llvm::BasicBlock* BB
