title: Print FPU registers in lldb
body: <p>How do you print FPU registers using lldb?</p>
  
  <p>In gdb, you would do something like <code>p $st0</code>, however doing the same in lldb results in the error: <code>error: use of undeclared identifier '$st0'</code>.</p>
  
  <p><code>register read st0</code> doesn't work either and gives the error <code>error: Invalid register name 'st0'.</code>.</p>
