/* The DEF_OPERATOR macro takes the following arguments:
NAME
The name of the operator, as a C string, but without the
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,
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.
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".
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 nonzero, 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 precede binary operators. */
