| <a name="index-Jumps"></a> |
| |
| <p>Other jumps are expressed by either <code>GOTO_EXPR</code> or |
| <code>RETURN_EXPR</code>. |
| </p> |
| <p>The operand of a <code>GOTO_EXPR</code> must be either a label or a |
| variable containing the address to jump to. |
| </p> |
| <p>The operand of a <code>RETURN_EXPR</code> is either <code>NULL_TREE</code>, |
| <code>RESULT_DECL</code>, or a <code>MODIFY_EXPR</code> which sets the return |
| value. It would be nice to move the <code>MODIFY_EXPR</code> into a |
| separate statement, but the special return semantics in |
| <code>expand_return</code> make that difficult. It may still happen in |
| the future, perhaps by moving most of that logic into |
| <code>expand_assignment</code>. |
