  70. <p>Other jumps are expressed by either <code>GOTO_EXPR</code> or
  71. <code>RETURN_EXPR</code>.
  72. </p>
  73. <p>The operand of a <code>GOTO_EXPR</code> must be either a label or a
  74. variable containing the address to jump to.
  75. </p>
  76. <p>The operand of a <code>RETURN_EXPR</code> is either <code>NULL_TREE</code>,
  77. <code>RESULT_DECL</code>, or a <code>MODIFY_EXPR</code> which sets the return
  78. value. It would be nice to move the <code>MODIFY_EXPR</code> into a
  79. separate statement, but the special return semantics in
  80. <code>expand_return</code> make that difficult. It may still happen in
  81. the future, perhaps by moving most of that logic into
  82. <code>expand_assignment</code>.
