A system, method and computer program product for compiling a source file and to generate a unitary data structure (UDS) containing information relating to symbols and associated global registers. The UDS permits assessment of symbol conflicts for global registers. The compiler also generates object files from related source files. The object files include the global symbol information relating to particular global registers, to enable diagnosis of conflicts between global symbols and registers.

1. A method of compiling and linking a source file, the method comprising:generating, using a compiler, global variable information pertaining to at least one global variable referenced in a source file; generating, using the compiler, a first object file from the source file, where the object file includes global variable information; linking the first object file with at least a second object file to generate an executable file; generating, during the linking process, a composite symbol table having a symbol entry for each global variable in at least one of the linked object files; examining, during the linking process, the composite symbol table and determining if at least one global variable conflict occurs; generating, during or after the linking process, a composite relocation table having at least one relation entry for resolving at least one global variable conflict determined during examination of the composite symbol table; performing, during or after the linking process, a relocation operation according to at least one relocation entry in the composite relocation table; and completing compilation of the first and second object files after the linking process and the relocation operation are completed.
