Public Attributes
int BlockNo
For a NoVal or VPHI DbgValue, which block it was generated in.
DbgValueProperties Properties
Qualifiers for the ValueIDNum above.
KindT Kind
Discriminator for whether this is a constant or an in-program value.

Class recording the (high level) value of a variable.

Identifies the value of the variable as a list of ValueIDNums and constant MachineOperands, or as an empty list for undef debug values or VPHI values which we have not found valid locations for. 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.
