Publisher's Synopsis
Excerpt from Machine Code Optimization Improving Executable Object Code
Another inefficiency deals with the use of the instruction set itself. The given architectures all have a set of addressing modes which can be used to represent the semantics of instruction operands. Included in this set are a number of location-relative modes which yield an effective address by giving an offset from the location of the operand or the start of the instruction. Often, the location-relative modes require less space and yield an effective address that is decoded (by the hardware) faster than absolute modes which simply name the effective address. However, the short offset employed limits the effective address to within a specified distance from the operand.
