Public Member Functions
LLVM_ABI DbgVariableRecord (const DbgVariableIntrinsic *DVI)
Create a new DbgVariableRecord representing the intrinsic DVI, for example the assignment represented by a dbg.value.
LLVM_ABI DbgVariableRecord (const DbgVariableRecord &DVR)
LLVM_ABI DbgVariableRecord (Metadata *Location, DILocalVariable *DV, DIExpression *Expr, const DILocation *DI, LocationType Type=LocationType::Value)
Directly construct a new DbgVariableRecord representing a dbg.value intrinsic assigning Location to the DV / Expr / DI variable.

◆ createUnresolvedDbgVariableRecord()

Used to create DbgVariableRecords during parsing, where some metadata references may still be unresolved.

Although for some fields a generic Metadata* argument is accepted for forward type-references, the verifier and accessors will reject incorrect types later on. The function is used for all types of DbgVariableRecords for simplicity while parsing, but asserts if any necessary fields are empty or unused fields are not empty, i.e. if the #dbg_assign fields are used for a non-dbg-assign type.
