class DbgValue

Declaration

class DbgValue { /* full declaration omitted */ };

Description

Class recording the (high level) _value_ of a variable. Identifies either the value of the variable as a ValueIDNum, or a constant MachineOperand. This class also stores meta-information about how the value is qualified. Used to reason about variable values when performing the second (DebugVariable specific) dataflow analysis.

Declared at: llvm/lib/CodeGen/LiveDebugValues/InstrRefBasedImpl.h:229

Member Variables

public LiveDebugValues::ValueIDNum ID

If Kind is Def, the value number that this value is based on. VPHIs set this field to EmptyValue if there is no machine-value for this VPHI, or the corresponding machine-value if there is one.

public Optional<llvm::MachineOperand> MO

If Kind is Const, the MachineOperand defining this value.

public int BlockNo

For a NoVal or VPHI DbgValue, which block it was generated in.

public LiveDebugValues::DbgValueProperties Properties

Qualifiers for the ValueIDNum above.

public LiveDebugValues::DbgValue::KindT Kind

Discriminator for whether this is a constant or an in-program value.
