; RUN: llvm-as < %s | llc
;; Date: Jul 8, 2003.
;; From: test/Programs/MultiSource/Olden-perimeter
;; Function: int %adj(uint %d.1, uint %ct.1)
;;
;; 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.
