You conditionally branch, using the opposite condition, over a branch, so that the bar only gets e ecuted if your condition was true. So to call a subroutine only if d0 is equal to zero:

        tst.w   d0
        bne     1$
        bar     subroutine
1$      more code...
Use local labels for stuff like this, otherwise you'll spend more time thinking of names than coding.
