Namespace: B2R2.FrontEnd.BinFile.ELF
Assembly: B2R2.FrontEnd.BinFile.dll
Base Type: obj
All Interfaces: IEquatable<UnwindingAction> , IStructuralEquatable , IComparable<UnwindingAction> , IComparable , IStructuralComparable

Represents unwinding action that can be performed to restore a register value during stack unwinding. This is referred to as "register rules" in the DWARF specification.

Union cases

Union case	Description
`ActionExpr Expr` Full Usage: `ActionExpr Expr` Parameters: Item : `Expr`	The previous value is located at the address produced by evaluating the expression. Item : `Expr`
`ActionValExpr Expr` Full Usage: `ActionValExpr Expr` Parameters: Item : `Expr`	The previous value is represented as the value produced by evaluating the expression. Item : `Expr`
`Offset int64` Full Usage: `Offset int64` Parameters: Item : `int64`	The previous value of this register is saved at the address CFA+N where CFA is the current CFA value and N is a signed offset. Item : `int64`
`Register RegisterID` Full Usage: `Register RegisterID` Parameters: Item : `RegisterID`	The previous value of this register is stored in another register numbered R. Item : `RegisterID`
`SameValue` Full Usage: `SameValue`	The register has not been modified from the previous frame.
`Undefined` Full Usage: `Undefined`	Has no recoverable value in the previous frame.
`ValOffset int` Full Usage: `ValOffset int` Parameters: Item : `int`	The previous value of this register is the value CFA+N where CFA is the current CFA value and N is a signed offset. Item : `int`
