   3    This file contains definitions of the various C++ operators,
   4    including both overloadable operators (like `+') and
   5    non-overloadable operators (like the `?:' ternary operator).

  27 /* The DEF_OPERATOR macro takes the following arguments:
  28
  29    NAME
  30
  31      The name of the operator, as a C string, but without the
  32      preceeding `operator'.  This is the name that would be given in
  33      the source program.  For `operator +', for example, this would be
  34      `+'.
  35
  36    CODE
  37
  38      The tree_code for this operator.  For `operator +', for example,
  39      this would be PLUS_EXPR.  Because there are no tree codes for
  40      assignment operators, the same tree-codes are reused; i.e.,
  41      `operator +' will also have PLUS_EXPR as its CODE.
  42
  43    NEW_MANGLING
  44
  45      The mangling prefix for the operator, as a C string, and as
  46      mangled under the new ABI.  For `operator +', for example, this
  47      would be "pl".
  48
  49    OLD_MANGLING
  50
  51      Analagous, but for the old ABI.
  52
  53    ARITY
  54
  55      The arity of the operator, or -1 if any arity is allowed.  (As
  56      for `operator ()'.)  Postincrement and postdecrement operators
  57      are marked as binary.
  58
  59    ASSN_P
  60
  61      A boolean value.  If non-zero, this is an assignment operator.
  62
  63    Before including this file, you should define DEFOPERATOR
  64    to take these arguments.
  65
  66    There is code (such as in grok_op_properties) that depends on the
  67    order the operators are presented in this file.  In particular,
  68    unary operators must preceed binary operators.  */

  70 /* Use DEF_SIMPLE_OPERATOR to define a non-assignment operator.  Its
  71    arguments are as for DEF_OPERATOR, but there is no need to provide
  72    an ASSIGNMENT_P argument; it is always zero.  */
