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
:
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
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.
45 The mangling prefix for the operator, as a C string, and as
46 mangled under the new ABI. For `operator +', for example
, this
51 Analagous
, but for the old ABI.
55 The arity of the operator
, or
-1 if any arity is allowed.
(As
56 for `
operator ()'.) Postincrement and postdecrement operators
61 A boolean value. If non-zero, this is an assignment operator.
63 Before including this file, you should define DEFOPERATOR
64 to take these arguments.
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. */
