llvm-6502/test/LLC/2003-07-08-BadCastToBool.ll

;; 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.
;; 
;; LLC Output for the basic block (LLVM assembly is shown below):
;; 
;; .L_adj_7_LL_4:
;;         sethi   0, %i0
;;         subcc   %i1, 2, %g0
;;         move    %icc, 1, %i0
;;         orn     %i0, %i1, %i0
;;         ba      .L_adj_7_LL_5
