Description
Replace an X based instruction using immediate, direct, indexed, or inherent
addressing mode by a Y one.
Replace an instruction using direct, direct bit, or direct relative addressing mode
to an instruction using the corresponding indirect addressing mode.
It also changes an instruction using X indexed addressing mode to an instruction
using indirect X indexed addressing mode.
Replace an instruction using X indirect indexed addressing mode by a Y one.
