Regarding how you'd know, I have no idea. This wasn't done in an APAR. Regarding LR 15,R5 surely you provided the equate of R5 (or some macro did); fix/enhance the equate/macro.
I see "yregs", for example, which apparently is owned by DFSMS, has no facility for adding the register-size attribute. You might request that they do so. Regarding LR / CPYA vs LAE: They are not equivalent. Sometimes the difference doesn't matter; sometimes it does. Macros that are adjusted incrementally tend to stay on the conservative side. And the "LR" has existed "forever".
