Abstract
Some embodiments include a processing subsystem that compiles program code to generate compiled program code. In these embodiments, while compiling the program code, the processing subsystem first identifies a pointer in the program code that points to an unspecified address space. The processing subsystem then analyzes at least a portion of the program code to determine one or more address spaces to which the pointer may point. Next, the processor updates metadata for the pointer to indicate the one or more address spaces to which the pointer may point, the metadata enabling a determination of an address space to which the pointer points during subsequent execution of the compiled program code.
