  24 Because it is a research compiler, SUIF is designed to be both flexible
  25 and extensible.  <STRONG>Annotations</STRONG>, which may contain arbitrary data
  26 structures, are the primary means of providing this extensibility.
  27 Objects that are derived from the <CODE>suif_object</CODE> class have lists of
  28 annotations associated with them.  This includes most of the major SUIF
  29 objects such as instructions, tree nodes, symbols, types, symbol tables,
  30 and file set entries.  New annotations can be declared by any program
  31 and used to record whatever information is needed within that program.
  32 They can also be written to the SUIF output files so that other programs
  33 can use them.  The <STRONG>annotation manager</STRONG> records the annotation names
  34 and the format of the data associated with each kind of annotation.
