Debugging registers

LibPyOSDev provides powerful debugging features. The register module provides the Register class, which is used to represent CPU registers.

Register(
    name: str,
    size: str,
    value: Any=0
)

The name parameter is the name of the register (e.g. AX, BX, SI, CS, …).
The size parameter is the size of the register (e.g. 1, 8, 16, 32, 64).
The value parameter is the value of the register, set to 0 by default. The class is not linked with CPU registers, so you need to update the value yourself after an operation if you want to get it.

To access a register, you can use the Register.symbol() method which returns its name. However, this function is called automatically so you are not forced to call it.

The __repr__() method returns this representation:

<Register NAME (SIZE-bit) = VALUE>
