Something peculiar here is that the default and another case jumps to the same
basic block:

  switch (D.4089_3) <default: L0, case 0 ... 7: <L3>, case 8: <L0>>

[...]

  # R86s_8 = PHI <0(2), 0(3), 0(6), 1(14)>
L0:
<L3>:
  D.4087_7 = D.4084_1 ^ 1;
  D.4086_9 = D.4087_7 & R86s_8;
  if (D.4086_9 != 0)
    goto <bb 8>;
  else
    goto <bb 9>;
