/* The DEF_OPERATOR macro takes the following arguments:
NAME
The name of the operator, as a C string, but without the
- preceeding `operator'. This is the name that would be given in
+ preceding `operator'. This is the name that would be given in
the source program. For `operator +', for example, this would be
`+'.
-
+
CODE
The tree_code for this operator. For `operator +', for example,
assignment operators, the same tree-codes are reused; i.e.,
`operator +' will also have PLUS_EXPR as its CODE.
- NEW_MANGLING
+ MANGLING
The mangling prefix for the operator, as a C string, and as
mangled under the new ABI. For `operator +', for example, this
would be "pl".
- OLD_MANGLING
-
- Analagous, but for the old ABI.
-
- ARITY
-
- The arity of the operator, or -1 if any arity is allowed. (As
- for `operator ()'.) Postincrement and postdecrement operators
- are marked as binary.
+ FLAGS
- ASSN_P
+ ovl_op_flags bits. Postincrement and postdecrement operators are
+ marked as binary.
- A boolean value. If non-zero, this is an assignment operator.
-
- Before including this file, you should define DEFOPERATOR
- to take these arguments.
+ Before including this file, you should define DEF_OPERATOR
+ to take these arguments.
There is code (such as in grok_op_properties) that depends on the
- order the operators are presented in this file. In particular,
- unary operators must preceed binary operators. */

- arguments are as for DEF_OPERATOR, but there is no need to provide
- an ASSIGNMENT_P argument; it is always zero. */
