   I have following code snippet:   
      
       cmp r9,1   
       je .one   
       add rdi,r9   
       sub rdx,r9   
       jmp .L0   
   .one:   
       inc rdi   
       dec rdx   
       jmp .L0   
      
   For some reason I did it like that and it seems that doesn't hurt, but   
   gives significant boost in some cases?   
   Am I doing it wrong or is this good practice?
