If you care about detecting bugs I would expect you to be
supportive rather than dismissive of this work, and helpful
in bringing it to fruition rather that putting it down or
questioning my priorities. Especially since the work was
prompted by your own (valid) complaint that GCC doesn't
diagnose them.
You don't really listen to what I am saying, I did not say
that we need another warning instead of fixing the wrong
optimization issue at hand.
But I am in good company, you don't listen to Jakub and Richi
either.
I certainly intend to fix bugs I'm responsible for introducing.
I always do if given the chance. I assume you are referring
to bug 86711 (and 86714). Fixing the underlying problem has
been on my mind since you first mentioned it, and on my to-do
list since last week (bug 86688).
I've started looking into fixing 86711 but as it turns out,
by avoiding folding non-nul-terminated strings, this patch
already fixes it as well as producing the output you expect
for the test case in 86714, and also fixes 86688.
So unless you intend to pursue your patch I will assign all
these bugs to myself, add the test cases to this patch, and
resubmit it. (I would normally prefer to deal with each bug
independently, but since I already have a working patch that
does the right thing I'd just as soon save the time and effort
and not try to break it up).
