Member Typedef Documentation

FragmentInfo

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

Definition at line 1127 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 1146 of file InstrRefBasedImpl.h.

LiveIdxT

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

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

Definition at line 1141 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 1150 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 1137 of file InstrRefBasedImpl.h.

OptFragmentInfo

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

Definition at line 1128 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 1162 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 1153 of file InstrRefBasedImpl.h.

ScopeToVarsT

using LiveDebugValues::InstrRefBasedLDV::ScopeToVarsT = DenseMap<const LexicalScope *, SmallSet<DebugVariableID, 4> >

Mapping from lexical scopes to variables in that scope.

Definition at line 1156 of file InstrRefBasedImpl.h.

VarAndLoc

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

Definition at line 1143 of file InstrRefBasedImpl.h.

VarToFragments

using LiveDebugValues::InstrRefBasedLDV::VarToFragments = DenseMap<const DILocalVariable *, SmallSet<FragmentInfo, 4> >

Definition at line 1132 of file InstrRefBasedImpl.h.
