If this 405 and 440 work includes string functions, how does their
performance compare to that of IBM's optimized 4xx string function library
(see e.g.
<http://www-03.ibm.com/chips/power/powerpc/newsletter/sep2003/ppc_process_at_work2.html>)?
CodeSourcery has been discussing with IBM the possibility of contributing
this library to the FSF and adding it to this add-on.
