Abstract

An executable program compiled according to a source instruction set architecture (source ISA) is loaded for execution by a target instruction set architecture (target ISA)-based hardware execution unit, wherein the source and target ISA's are different. The loading includes mapping a compiler built-in helper function in the executable program to a target ISA machine instruction. The loaded program is then executed. As part of the execution, the helper function is replaced with the target ISA machine instruction to which the helper function was mapped, and the target ISA machine instruction is executed rather than the helper function.
