Seems perfectly doable, no objections.
It will probably take me longer to integrate it in the build system
then to get the scripts ready.
I will start by placing the ruby tool and documentation there, and
later on, integrate it in the build system.
Hope that you get re-motivated to review our patc

Hi Richard,
Thanks for your quick reply, and again, thanks for the reviews.
We have already started to make very significant changes to the port
based on your comments. ;-)

Hi Richard,
Thank you so much for your reviews.
I will start working on improving the code straight away to try to
minimize waiting times.
However lets just address the elephant in the room.
Indeed we have the TCG definitions being generated.
However we are very serious about wanting to upstream

This is xnor(N, V) & !Z, and since as you now know xnor = eqv, you can perform
this in just two steps.
tcg_gen_eqv_tl(ret, cpu_Nf, cpu_Vf);
tcg_gen_andc_tl(ret, ret, cp
