  48    This is the assembly form of a switch-statement in C.
  49    The "sub is optional.  If there is none, then X will be zero.
  50    X is the value of the first case,

  52
  53    This results in case offsets printed on the form:
  54     case N: -> case_address
  55    where N is an estimation on the corresponding 'case' operand in C,
  56    and case_address is where execution of that case continues after the
  57    sequence presented above.
  58
  59    The old style of output was to print the offsets as instructions,
  60    which made it hard to follow "case"-constructs in the disassembly,
  61    and caused a lot of annoying warnings about undefined instructions.
