Enum Location

pub enum Location<'a> {
    Register(RegisterLocation<'a>),
    Address(AddressLocation<'a>),
    FrameBase(FrameBaseLocation<'a>),
    RegisterOffset(RegisterOffsetLocation<'a>),
    Expression(ExpressionLocation<'a>),
    Unavailable(UnavailableLocation<'a>),
    Composite(CompositeLocation<'a>),
    Unknown(UnknownLocation<'a>),
}

Where the value of a variable or a parameter lives, as described by a DWARF location expression.

Variants

Register(RegisterLocation<'a>)

The value is associated with a register (e.g. DW_OP_reg5)

Address(AddressLocation<'a>)

The value is located at a fixed memory address (e.g. DW_OP_addr)

FrameBase(FrameBaseLocation<'a>)

The value is located in memory at an offset of the frame base (e.g. DW_OP_fbreg)

RegisterOffset(RegisterOffsetLocation<'a>)

The value is located in memory at an offset of a register (e.g. DW_OP_breg7 +8)

Expression(ExpressionLocation<'a>)

A DWARF expression that is not evaluated by LIEF

Unavailable(UnavailableLocation<'a>)

The value is not available (e.g. optimized out)

Composite(CompositeLocation<'a>)

The value is split into several pieces (DW_OP_piece/DW_OP_bit_piece)

Unknown(UnknownLocation<'a>)

A location that is not recognized

Trait Implementations
