Hi Gerald,

   The attached patch updates the gcc html documentation to mention the 
new RX command line option that I checked in today.  Is this patch OK to 
apply ?

Cheers
   Nick

+    used to disable the generation of the <code>SCMPU</code>, <code>SMOVU</code>,
+    <code>SMOVB</code>, <code>SMOVF</code>, <code>SUNTIL</code>, <code>SWHILE</code>

+    of the processor.  The new option can be used when the programmer is
+    concerned that the I/O space might be accessed.  The default is still to
