; 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.
