Abstract
An improved compilation and linkage system for use in operating a computer to generate a cross-module optimized executable code file from a plurality of source files and object files. The source files are compiled to intermediate code files using a compiler sub-system. In the preferred embodiment of the present invention, the intermediate code files consist of intermediate language instructions that can be optimized for execution on a predetermined computer and a global symbol table. The compiler sub-system can also be used to generate conventional object code files if desired. A linkage sub-system is then used to cross-module optimize the code in a plurality of intermediate code files and link the resultant object code with any other object code files to generate the executable code file for execution on the computer in question. To the programmer, the operation of the compiler and linkage sub-systems of the present invention is essentially indistinguishable from that of a conventional compiler and linkage sub-system that lacks cross-module optimization.
