 ;; About the test cases: there are various optimizations in the engine
 ;; for different shapes of a pointer+offset.  Constant pointers are
 ;; resolved early; large offsets are folded early using explicit code
 ;; with an overflow check (but "large" depends on 32-bit vs 64-bit);
 ;; wait/notify fold offsets early regardless; zero offsets lead to
 ;; tighter code with variable pointers; and don't get me started on
 ;; alignment checks.  These test cases are not exhaustive but aim
 ;; to test at least some things.

 ;; TODO: more sizes for all operations, though this is not critical
 ;; TODO: sign extending loads, again not critical
