struct BlockFrequencyInfoImplBase::LoopData

Declaration

struct BlockFrequencyInfoImplBase::LoopData { /* full declaration omitted */ };

Description

Data about a loop. Contains the data necessary to represent a loop as a pseudo-node once it's packaged.

Declared at: llvm/include/llvm/Analysis/BlockFrequencyInfoImpl.h:214

Member Variables

public llvm::BlockFrequencyInfoImplBase::LoopData* Parent

The parent loop.

public bool IsPackaged = false

Whether this has been packaged.

public uint32_t NumHeaders = 1

Number of headers.

public llvm::BlockFrequencyInfoImplBase::LoopData:: ExitMap Exits

Successor edges (and weights).

public llvm::BlockFrequencyInfoImplBase::LoopData:: NodeList Nodes

Header and the members of the loop.

public llvm::BlockFrequencyInfoImplBase::LoopData:: HeaderMassList BackedgeMass

Mass returned to each loop header.

public llvm::BlockFrequencyInfoImplBase::BlockMass Mass

public llvm::BlockFrequencyInfoImplBase::Scaled64 Scale
