<div dir="ltr" class="">Hi All,
<div class=""><br class="">
</div>
<div class="">I've composed a draft roadmap for this new target. I've
decided to try Github's "Projects" feature, as it provides a
clearer view to see all the blockers and action items, IMAO.
Here is the link:</div>
<div class=""><a href="https://github.com/M680x0/M680x0-mono-repo/projects" moz-do-not-send="true" class="">https://github.com/M680x0/M680x0-mono-repo/projects</a><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">Currently I only created two major milestones: Becoming an
experimental target and becoming an official target. For each
milestone, I've listed the expected features, estimated time
frame (though I'm not really confident on that), and most
importantly, the blockers for the milestone.</div>
<div class="">Fortunately, all of our essential features are complete
(e.g. ISel, MC), so there will be more house cleaning tasks
and bug fixing than adding new features in the second
milestone.</div>
<div class=""><br class="">
</div>
<div class="">In addition to the aforementioned two milestones, I've
added "be able to run toy programs" as a separate milestone to
accommodate some more urgent tasks right now. More
specifically, driver problems that make Clang unable to
leverage all our components.</div>
<div class=""><br class="">
</div>
<div class="">Thank you!</div>
<div class="">Min</div>

<div class="">Unfortunately, we don't have a centralised
infrastructure like GCC. Each target community is
responsible for maintaining their own buildbots.</div>

<div class="">All we provide is the "build master", which

<div class="">It should be trivial to copy & paste an existing
bot config and change to add the experimental hardware
(once it's in the tree).</div>
<div class=""><br class="">
</div>
<div class="">Pay attention to the version of buildbot you install,
as using an even slightly different version can cause
weird errors.</div>

<div class="">Awesome! We have buildbots with test-suite running,
you can copy those, too. There were some QEMU bots in
the past, I'm not sure they're around, but the infra to
run them should still be there.</div>
