|
|
Other jumps are expressed by either <code>GOTO_EXPR</code> or
|
|
<code>RETURN_EXPR</code>.
|
|
|
|
<p>The operand of a <code>GOTO_EXPR</code> must be either a label or a
|
|
variable containing the address to jump to.
|
|
|
|
<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>.
