  25 /* decode_instructions -- dump a range of addresses as native instructions
  26    This implements the protocol required by the HotSpot PrintAssembly option.
  27 
  28    The starting and ending addresses are within the current process's address space.
  29 
  30    The option string, if not empty, is interpreted by the disassembler implementation.
  31 
  32    The printf callback is 'fprintf' or any other workalike.
  33    It is called as (*printf_callback)(printf_stream, "some format...", some, format, args).
  34 
  35    The event callback receives an event tag (a string) and an argument (a void*).
  36    It is called as (*event_callback)(event_stream, "tag", arg).
  37 
  38    Events:
  39      <insn pc='%p'>             begin an instruction, at a given location
  40      </insn pc='%d'>            end an instruction, at a given location
  41      <addr value='%p'/>         emit the symbolic value of an address
  42 
  43    A tag format is one of three basic forms: "tag", "/tag", "tag/",
  44    where tag is a simple identifier, signifying (as in XML) a element start,
  45    element end, and standalone element.  (To render as XML, add angle brackets.)
