@ -3819,25 +3819,23 @@ transfer to a specified function, with its incoming arguments bound to
the specified values. Upon a '<tt><a href="#i_ret">ret</a></tt>'
instruction in the called function, control flow continues with the
instruction after the function call, and the return value of the
function is bound to the result argument. If the '<tt><a href="#i_ret">ret</a>
</tt>' instruction returns multiple values then the return values of the
function are only accessible through a '<tt><a href="#i_getresult">getresult</a>
</tt>' instruction. This is a simpler case of
the <a href="#i_invoke">invoke</a> instruction.</p>
function is bound to the result argument. If the callee returns multiple
values then the return values of the function are only accessible through
the '<tt><a href="#i_getresult">getresult</a></tt>' instruction.</p>
