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, this would be PLUS_EXPR. Because there are no tree codes for assignment operators, the same tree-codes are reused; i.e., `operator +' will also have PLUS_EXPR as its CODE. NEW_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. ASSN_P A boolean value. If non-zero, this is an assignment operator. Before including this file, you should define DEFOPERATOR 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. */ /* Use DEF_SIMPLE_OPERATOR to define a non-assignment operator.
