Member Typedef Documentation

◆ FragmentInfo

using LiveDebugValues::InstrRefBasedLDV::FragmentInfo = DIExpression::FragmentInfo

Definition at line 1120 of file InstrRefBasedImpl.h.

◆ InValueT

using LiveDebugValues::InstrRefBasedLDV::InValueT = std::pair<MachineBasicBlock *, DbgValue *>

Type for a live-in value: the predecessor block, and its value.

Definition at line 1139 of file InstrRefBasedImpl.h.

◆ LiveIdxT

using LiveDebugValues::InstrRefBasedLDV::LiveIdxT = SmallDenseMap<const MachineBasicBlock *, DbgValue *, 16>

Live in/out structure for the variable values: a per-block map of variables to their values.

Definition at line 1134 of file InstrRefBasedImpl.h.

◆ LiveInsT

using LiveDebugValues::InstrRefBasedLDV::LiveInsT = SmallVector<SmallVector<VarAndLoc, 8>, 8>

Vector (per block) of a collection (inner smallvector) of live-ins.

Used as the result type for the variable value dataflow problem.

Definition at line 1143 of file InstrRefBasedImpl.h.

◆ MLocTransferMap

using LiveDebugValues::InstrRefBasedLDV::MLocTransferMap = SmallDenseMap<LocIdx, ValueIDNum>

Machine location/value transfer function, a mapping of which locations are assigned which new values.

Definition at line 1130 of file InstrRefBasedImpl.h.

◆ OptFragmentInfo

using LiveDebugValues::InstrRefBasedLDV::OptFragmentInfo = std::optional<DIExpression::FragmentInfo>

Definition at line 1121 of file InstrRefBasedImpl.h.

◆ ScopeToAssignBlocksT

using LiveDebugValues::InstrRefBasedLDV::ScopeToAssignBlocksT = DenseMap<const LexicalScope *, SmallPtrSet<MachineBasicBlock *, 4>>

Mapping from lexical scopes to blocks where variables in that scope are assigned.

Such blocks aren't necessarily "in" the lexical scope, it's just a block where an assignment happens.

Definition at line 1155 of file InstrRefBasedImpl.h.

◆ ScopeToDILocT

using LiveDebugValues::InstrRefBasedLDV::ScopeToDILocT = DenseMap<const LexicalScope *, const DILocation *>

Mapping from lexical scopes to a DILocation in that scope.

Definition at line 1146 of file InstrRefBasedImpl.h.

◆ ScopeToVarsT

using LiveDebugValues::InstrRefBasedLDV::ScopeToVarsT

Initial value:

DenseMap<const LexicalScope *, SmallSet<DebugVariableID, 4>>

Definition DenseMap.h:700

Mapping from lexical scopes to variables in that scope.

Definition at line 1149 of file InstrRefBasedImpl.h.

◆ VarAndLoc

using LiveDebugValues::InstrRefBasedLDV::VarAndLoc = std::pair<DebugVariableID, DbgValue>

Definition at line 1136 of file InstrRefBasedImpl.h.

◆ VarToFragments

using LiveDebugValues::InstrRefBasedLDV::VarToFragments

Initial value:

DenseMap<const DILocalVariable *, SmallSet<FragmentInfo, 4>>

Definition at line 1125 of file InstrRefBasedImpl.h.
