Detailed Description

Member Typedef Documentation
◆ FragmentInfo
Definition at line 1041 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 1060 of file InstrRefBasedImpl.h.
◆ LiveIdxT
Live in/out structure for the variable values: a per-block map of variables to their values.
Definition at line 1055 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 1064 of file InstrRefBasedImpl.h.
◆ MLocTransferMap
Machine location/value transfer function, a mapping of which locations are assigned which new values.
Definition at line 1051 of file InstrRefBasedImpl.h.
◆ OptFragmentInfo
| using LiveDebugValues::InstrRefBasedLDV::OptFragmentInfo = std::optional<DIExpression::FragmentInfo> |
Definition at line 1042 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 1075 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 1067 of file InstrRefBasedImpl.h.
◆ ScopeToVarsT
| using LiveDebugValues::InstrRefBasedLDV::ScopeToVarsT = DenseMap<const LexicalScope *, SmallSet<DebugVariable, 4> > |
Mapping from lexical scopes to variables in that scope.
Definition at line 1070 of file InstrRefBasedImpl.h.
◆ VarAndLoc
| using LiveDebugValues::InstrRefBasedLDV::VarAndLoc = std::pair<DebugVariable, DbgValue> |
Definition at line 1057 of file InstrRefBasedImpl.h.
◆ VarToFragments
| using LiveDebugValues::InstrRefBasedLDV::VarToFragments = DenseMap<const DILocalVariable *, SmallSet<FragmentInfo, 4> > |
Definition at line 1046 of file InstrRefBasedImpl.h.
