I've committed, on behalf of Red Hat and the original author, Graydon
Hoare, the attached patch which implements, for SID only, an
implementation of delayed read/writes which is useful for implementing
cpus with exposed pipelines, delay slots and parallel execution. I
think the user level description which has been added cgen/doc/rtl.texi
describes the new functionality pretty well.



There is no effect on existing SID ports or opcodes. This new 
functionaility has been used in the implementation of the Morpho ms1 
(patch on the way).

This patch also adds the automatic generation of streaming methods for cgen hardware to each cpu.

Regards,
Dave
