Abstract
A method, apparatus, and article of manufacture for the inclusion of extended relocation types and operations performed thereon in a relocation directory within an object module or load module. The relocation directory includes a field to describe the referenced item relocated into the address constant location within the text, which may be a numerical value, symbol, address, set of data or instructions or symbol. The relocation directory further includes a field to describe the operation performed on the referenced item and the present contents of the address constant, which includes operations such as subtraction, addition, division, multiplication, logical AND, logical OR, shifting, logical XOR, and moving. The result of the operation performed on the referenced item and the content of the address constant is relocated into the address constant location.
