; Gather non-machine specific tests for the transformations in
; CodeGen/SelectionDAG/TargetLowering.  Currently, these
; can't be tested easily by checking the SDNodes that are
; the data structures that these transformations act on.
; Therefore, use X86 assembler output to check against.

; rdar://11195364 A problem with the transformation:
;  If all of the demanded bits on one side are known, and all of the set
;  bits on that side are also known to be set on the other side, turn this
;  into an AND, as we know the bits will be cleared.
; The known set (one) bits for the arguments %xor1 are not the same, so the
; transformation should not occur
