; The register+memory form of the BT instruction should be usable on
; pentium4, however it is currently disabled due to the register+memory
; form having different semantics than the register+register form.

; Test these patterns:
;    (X & (1 << N))  != 0  -->  BT(X, N).
;    ((X >>u N) & 1) != 0  -->  BT(X, N).
; as well as several variations:
;    - The second form can use an arithmetic shift.
;    - Either form can use == instead of !=.
;    - Either form can compare with an operand of the &
;      instead of with 0.
;    - The comparison can be commuted (only cases where neither
;      operand is constant are included).
;    - The and can be commuted.
