I don't care if you call it "politically correct" (I wouldn't), but you
will have to find a way to deliver what you say in a way others don't
perceive as attacking them, insulting them, and being hostile. Those are
the baseline requirements to participate in this community and work on this
project. As I said before, you are always free to work on other compiler
projects or start your own if you find this community not to your liking.
Open source is a big place. =]

I understand you are frustrated, but I have said on several occasions that
repeating yourself is not helpful.

I'm sorry, but given the tone and approach you have taken, I don't have
time, energy, or motivation to continue to invest here. I'm going back to
other things. Having read all of these threads, I am thoroughly convinced
by the positions put forward by others.

My advice to you in my first email stands. If you want to make progress,
more emails will not help. I encourage you to start writing code and
demonstrating through specific proposed modifications (likely prototyped on
a local branch or GitHub fork) and demonstrate clear evidence of the
improved reliability without degraded performance of benchmarks.

I think that is your path forward, and I don't plan on continuing to engage
in what comes off to me as a hostile and repetitive email thread (this one,
and the others you have started).
