--- Comment #46 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
i just added svstate_i which is the same as pc_i so that this can also
be set whilst the processor is STOPPED.

then, test_runner.py uses svstate_i.ok to set svstate and releases it
at the same time as pc_i.ok when START is sent.

in theeeeorryyyy that should solve the reset problem for starting a new
program, because (just like pc_i) when the new svstate_i is passed in,
it is no longer read from the StateRegs regfile.

that was probably the problem.
