EPSW was new with z/Architecture, and was also added to the ESA/390 instruction set on z/Architecture machines. Compilation for a z900 or later will provide what you need. QED. Those creepy tables in Appendix B of the Principles of Operation provide this information, once you intuit that "New in z/Architecture" (N, N3) is "z900". The presence of instructions added after that point are indicated by a facilities bit from STFL/STFLE.
