1. A computer program product for facilitating processing within an emulated computing environment, said computer program product comprising: a non-transitory computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising: identifying, by a processor that is based on one system architecture, one or more system-provided routines referenced within an application written for another system architecture different from the one system architecture, the another system architecture having a different instruction set than the one system architecture, the application to be emulated by the processor, in which at least one or more portions of code of the application written for the another system architecture is to be translated into equivalent code of the one system architecture, and wherein the identifying identifies one or more defined routine names or one or more defined routine signatures of the one or more system-provided routines; and based on identifying a system-provided routine in the application written for the another system architecture, determining whether a native code equivalent is available for the identified system-provided routine, and based on determining that the native code equivalent is available, using a pointer to point to the native code equivalent, wherein native code is provided for the system-provided routine instead of emulated code for the system-provided routine, the native code comprising non-translated native code, wherein the native code for the system-provided routine is not native code that has been translated by emulator code, and wherein the system-provided routine is a routine that is included with a system component as a standard routine of the system component, and wherein the system-provided routine comprises a sort routine, a print routine, a copy routine. a mathematical function or a GETMAIN service.
