Hi Frank There are a few relatively minor differences in code generated but these tend to be mostly focused on taking advantage of z15. I assume you're not compiling for z15 (yet)? Other than z15 exploitation, this is like a really big continuous delivery PTF. There is always the possibility of different code generation in a PTF due to bug fixes. But in this case, there's really not a lot different unless you use z15, UTF-8, dynamic length elementary data items or 64-bit.
