  • Patent number: 6845502
    Abstract: Disclosed is a system, method, and program for producing an executable file for execution by a computer. The computer receives a plurality of programming language statements comprising a source program and translates the source program into an object module. The object module includes a symbol reference, a symbol definition, attribute information for the symbol reference derived from the language, and attribute information for the symbol definition derived from the language statements. The computer binds the object modules into a program object and resolves in the program object an external symbol reference in the object module with an external symbol definition in another object module. The attribute information is available when binding object modules into the program object.

  • Patent number: 6631516
    Abstract: Disclosed is a method, system, and information bearing medium for associating attribute information with symbols. A command is processed associating user specified attribute information with a symbol definition or reference. The user specified attribute information is added to an object file including the symbol definition or reference. The attribute information may then be used to determine compatibility when resolving references to the symbol. Further, the user specified attribute information may also be associated with an address constant.

  • Patent number: 6578194
    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.
