One embodiment of the present invention sets forth a technique for extracting a memory address offset from a 64-bit type-conversion expression included in high-level source code of a computer program. The technique involves receiving the 64-bit type-conversion expression, where the 64-bit type-conversion expression includes one or more 32-bit expressions, determining a range for each of the one or more 32-bit expressions, calculating a total range by summing the ranges of the 32-bit expressions, determining that the total range is a subset of a range for a 32-bit unsigned integer, calculating the memory address offset based on the ranges for the one or more 32-bit expressions, and generating at least one assembly-level instruction that references the memory address offset. |
