struct SelectionDAGBuilder::StatepointLoweringInfo

Declaration

struct SelectionDAGBuilder::StatepointLoweringInfo { /* full declaration omitted */ };

Describes a gc.statepoint or a gc.statepoint like thing for the purposes of lowering into a STATEPOINT node.

public SmallVector<const llvm::Value*, 16> Bases: Bases[i] is the base pointer for Ptrs[i]. Together they denote the set of gc pointers this STATEPOINT has to relocate.
public SmallVector<const llvm::Value*, 16> Ptrs
public SmallVector<const llvm::GCRelocateInst*, 16> GCRelocates: The set of gc.relocate calls associated with this gc.statepoint.
public ArrayRef<const llvm::Use> GCArgs: The full list of gc arguments to the gc.statepoint being lowered.
public const llvm::Instruction* StatepointInstr = nullptr: The gc.statepoint instruction.
public ArrayRef<const llvm::Use> GCTransitionArgs: The list of gc transition arguments present in the gc.statepoint being lowered.
public unsigned int ID = -1: The ID that the resulting STATEPOINT instruction has to report.
public TargetLowering::CallLoweringInfo CLI: Information regarding the underlying call instruction.
public ArrayRef<const llvm::Use> DeoptState: The deoptimization state associated with this gc.statepoint call, if any.
public uint64_t StatepointFlags = -1: Flags associated with the meta arguments being lowered.
public unsigned int NumPatchBytes = -1: The number of patchable bytes the call needs to get lowered into.
public const llvm::BasicBlock* EHPadBB = nullptr: The exception handling unwind destination, in case this represents an invoke of gc.statepoint.
