Public Types
using FragmentInfo = DIExpression::FragmentInfo
using OptFragmentInfo = std::optional<DIExpression::FragmentInfo>
using VarToFragments
using MLocTransferMap = SmallDenseMap<LocIdx, ValueIDNum>
Machine location/value transfer function, a mapping of which locations are assigned which new values.
using LiveIdxT = SmallDenseMap<const MachineBasicBlock *, DbgValue *, 16>
Live in/out structure for the variable values: a per-block map of variables to their values.
using VarAndLoc = std::pair<DebugVariableID, DbgValue>
using InValueT = std::pair<MachineBasicBlock *, DbgValue *>
Type for a live-in value: the predecessor block, and its value.
using LiveInsT = SmallVector<SmallVector<VarAndLoc, 8>, 8>
Vector (per block) of a collection (inner smallvector) of live-ins.
using ScopeToDILocT = DenseMap<const LexicalScope *, const DILocation *>
Mapping from lexical scopes to a DILocation in that scope.
using ScopeToVarsT
Mapping from lexical scopes to variables in that scope.
using ScopeToAssignBlocksT = DenseMap<const LexicalScope *, SmallPtrSet<MachineBasicBlock *, 4>>
Mapping from lexical scopes to blocks where variables in that scope are assigned.

◆ FragmentInfo

◆ InValueT

◆ LiveIdxT

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

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

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

Definition at line 1130 of file InstrRefBasedImpl.h.

◆ OptFragmentInfo

◆ ScopeToAssignBlocksT

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

◆ ScopeToVarsT

Initial value:

Mapping from lexical scopes to variables in that scope.

Definition at line 1149 of file InstrRefBasedImpl.h.
