Sum two bits from different positions and registers

by Scott Dattalo Given two bits at any bit position of any arbitrary registers, what's the fastest way to find their sum and place that into yet another bit position of an arbitrary register?

I get 6-cycles:

     movlw    1<<result_bit_position
     bcf      result,result_bit_position
     btfsc    x1,x1_bit_position
      xorwf   result,f
     btfsc    x2,x2_bit_position
      xorwf   result,f
