NAME

CPU::x86_64::InstructionWriter::Label - Object representing a jump target in the code

VERSION

version 0.002

DESCRIPTION

Forward-jumps in X86 can be fairly difficult because the instructions are variable length, and depending on how far the jump needs to go, the jump instruction itself can be variable-length which affects the address it jumps to. The InstructionWriter inserts these objects as place holders and then resolves their address later.

ATTRIBUTES

name

The user-readable name of the label

relative_to

The constant or placeholder object representing the start address for the assembled unit in which this label was declared.

offset

The address of this label, relative to 'relative_to'.

CONSTRUCTOR

Use "get_label" in CPU::x86_64::InstructionWriter to create labels.
