  23 Symbol tables contain the definitions of the symbols and types used
  24 within a SUIF program.  Each symbol table is associated with an object
  25 corresponding to a particular scope.  For example, a procedure symbol
  26 table is attached to the abstract syntax tree representing the body of
  27 the procedure.  The symbol tables can be reached through the
  28 corresponding objects and vice versa.

  32 This section describes the symbol table hierarchy and the details of the
  33 symbol table operations, such as looking up symbol table entries and
  34 adding new entries.  It also explains how the symbol tables handle the
  35 task of assigning unique ID numbers to the symbols and types.  The
  36 <TT>`symtab.h'</TT> and <TT>`symtab.cc'</TT> files contain the code for symbol
  37 tables.
