I've got a patch for it, just haven't sent it in yet.  See

It's not enough case.

The code that I expect is the following.

_func:
  tst #4, r1
  bne .L6
  tst #1, r1
  bne .L7
  tst #2, r1
  bne .L8
  bra _f4
.L8:
  bra _f3
.L6:
  bra _f1
.L7:
  bra _f2

Right, I haven't sent the patch in yet.  The other bug needs to be fixed first;
the TST patch triggers an ICE otherwise.
