Hi Gerald,
The attached patch updates the gcc html documentation to mention the

apply ?
Cheers
Nick

+ <li>A new command line option <code>-mno-allow-string-insns</code> can be
+ 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>
+ and <code>RMPA</code> instructions. An erratum released by Renesas shows
+ that it is unsafe to use these instructions on addresses with the I/O space
+ 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
