  /* decode_instructions -- dump a range of addresses as native instructions
     This implements the protocol required by the HotSpot PrintAssembly option.
  
!    The starting and ending addresses are within the current process's address space.
!    The start_va, end_va is the virtual address the region of memory to
+    disasemble and buffer contains the instructions to decode,
+    Disassembling instructions in the current address space is done by
+    having start_va == buffer.
  
     The option string, if not empty, is interpreted by the disassembler implementation.
  
     The printf callback is 'fprintf' or any other workalike.
     It is called as (*printf_callback)(printf_stream, "some format...", some, format, args).
