4.8. Itanium Addressing Modes

The topic of addressing modes—the means of specifying locations—is much simpler for an EPIC or RISC architecture than for CISC architectures. We have split our discussion of addressing modes into two parts: This section discusses Itanium addressing modes, while the next section explores addressing modes that are used in other computer architectures.

Most of the Itanium instructions that operate on integer or Boolean data employ the same immediate and register direct addressing modes as the arithmetic instructions. A good way to understand addressing modes is always to seek an answer to the question, “Where, and through what means, can the data be found?”

4.8.1. Immediate Addressing

With immediate addressing, the ...
