struct LiveRange::Segment

Declaration

struct LiveRange::Segment { /* full declaration omitted */ };

Description

This represents a simple continuous liveness interval for a value. The start point is inclusive, the end point exclusive. These intervals are rendered as [start,end).

Declared at: llvm/include/llvm/CodeGen/LiveInterval.h:161

Member Variables

public llvm::SlotIndex start

public llvm::SlotIndex end

public llvm::VNInfo* valno = nullptr

Method Overview

• public Segment()
• public Segment(llvm::SlotIndex S, llvm::SlotIndex E, llvm::VNInfo * V)
• public bool contains(llvm::SlotIndex I) const
• public bool containsInterval(llvm::SlotIndex S, llvm::SlotIndex E) const
• public void dump() const
