ABSTRACT:
A computer system, method of compiling, and method of accessing an address space utilize a data representation of a pointer that is smaller than the width of the address space during runtime of a computer program to retrieve a selected memory address in the address space whenever an access to the address space is required. For uses of the pointer that do not require an access to the address space, such as many arithmetic operations, the smaller data representation of the pointer is used. Compilation of a computer program including a reference to a pointer results in the generation of mapping code that generates a data representation of a pointer that is mapped to a selected memory address in the address space during execution of the computer program. Compilation also results in generation of retrieval code in the computer program that retrieves, for each use of the pointer that requires an access to the address space, the selected memory address during execution of the computer program using the data representation of the pointer.
