   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      preceding `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    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    ARITY
  50
  51      The arity of the operator, or -1 if any arity is allowed.  (As
  52      for `operator ()'.)  Postincrement and postdecrement operators
  53      are marked as binary.
  54
  55    ASSN_P
  56
  57      A boolean value.  If nonzero, this is an assignment operator.
  58
  59    Before including this file, you should define DEFOPERATOR
  60    to take these arguments.
  61
  62    There is code (such as in grok_op_properties) that depends on the
  63    order the operators are presented in this file.  In particular,
  64    unary operators must precede binary operators.  */
  65
  66 /* Use DEF_SIMPLE_OPERATOR to define a non-assignment operator.  Its
  67    arguments are as for DEF_OPERATOR, but there is no need to provide
  68    an ASSIGNMENT_P argument; it is always zero.  */
