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).

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

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