This chapter provides some basic information regarding addressing modes and the associated address manipulations on the x86-64 architecture.
The addressing modes are the supported methods for accessing a value in memory using the address of a data item being accessed (read or written). This might include the name of a variable or the location in an array.
The basic addressing modes are:
- Register
- Immediate
- Memory
Each of these modes is described with examples in the following sections. Additionally, a simple example for accessing an array is presented.
