--- Comment #21 from Hal Finkel <hfinkel at anl.gov> ---
The PPC backend now properly tracks CR bits, and the current creqv definition
reads:

def CREQV  : XLForm_1<19, 289, (outs crbitrc:$CRD),
                               (ins crbitrc:$CRA, crbitrc:$CRB),
                      "creqv $CRD, $CRA, $CRB", IIC_BrCR,
                      [(set i1:$CRD, (not (xor i1:$CRA, i1:$CRB)))]>;

I assume this bug has now been fixed.
