Constructor & Destructor Documentation

◆ WorkingData()

llvm::BlockFrequencyInfoImplBase::WorkingData::WorkingData ( const BlockNode Node)

Definition at line 278 of file BlockFrequencyInfoImpl.h.

Member Function Documentation

◆ getContainingLoop()

LoopData* llvm::BlockFrequencyInfoImplBase::WorkingData::getContainingLoop ( ) const

◆ getMass()

BlockMass& llvm::BlockFrequencyInfoImplBase::WorkingData::getMass ( )

Get the appropriate mass for a node.

Get appropriate mass for Node. If Node is a loop-header (whose loop has been packaged), returns the mass of its pseudo-node. If it's a node inside a packaged loop, it returns the loop's mass.

Definition at line 327 of file BlockFrequencyInfoImpl.h.

◆ getPackagedLoop()

LoopData* llvm::BlockFrequencyInfoImplBase::WorkingData::getPackagedLoop ( ) const

◆ getResolvedNode()

BlockNode llvm::BlockFrequencyInfoImplBase::WorkingData::getResolvedNode ( ) const

Resolve a node to its representative.

Get the node currently representing Node, which could be a containing loop.

This function should only be called when distributing mass. As long as there are no irreducible edges to Node, then it will have complexity O(1) in this context.

In general, the complexity is O(L), where L is the number of loop headers Node has been packaged into. Since this method is called in the context of distributing mass, L will be the number of loop headers an early exit edge jumps out of.

Has Loop been packaged up?
