| ;; Errors: (1) cast-int-to-bool was being treated as a NOP (i.e., the int |
| ;; register was treated as effectively true if non-zero). |
| ;; This cannot be used for later boolean operations. |
| ;; (2) (A or NOT(B)) was being folded into A orn B, which is ok |
| ;; for bitwise operations but not booleans! For booleans, |
| ;; the result has to be compared with 0. |
