A system, method and computer program product for compiling a source file and to generate a data structure associating a global symbol with a global register referenced in the source file. The data structure enables a linker to initialize the global registers. The compiler also generates an object file from the source file. The object file includes the global register information. A linker links the object file potentially with at least one other object file or shared library to thereby generate an executable file or shared library. The linker uses the global symbol information contained in the object file to initialize the global registers and to perform relocation operations.

[ What is claimed is:] [1.] A method of initialization of a global register comprising:generating, by a compiler, global register information pertaining to at least a single global variable referenced in a source file;generating, by said compiler, an object file from said source file, said object file comprising said global variable information, while not identifying global symbol conflicts, and not performing relocations; andlinking, by a linker, said object file with at least one of another object file and a shared library to thereby generate an executable file, using said global variable information contained in said object file to initialize at least a single global register and to identify variable conflicts with respect to said at least a single global register, the linker warning if any shared library that was referenced during the linking uses global registers in a fashion incompatible with an object being built.
