The basic signature is ‘<samp>code, type, [operands]<!-- /@w --></samp>’. +<code>code</code> is the <code>TREE_CODE</code>, and <code>type</code> is a tree +representing the <code>TREE_TYPE</code>. These are followed by the +operands, each of which is also a tree. +</p> +</dd> +</dl> + + + + + + +</body> +</html> |
