+; CHECK-NEXT: and sp, x9, #0xffffffffffffffe0
+; CHECK-NEXT: .seh_stackalloc 80
+; CHECK-NEXT: .seh_endprologue
----------------
The prologue should end after the set_set_fp; it makes no sense to try to represent the "and" in the SEH unwind tables.  (I thought we discussed this before at some point, but maybe I'm confusing it with something else...)
