> I can't reproduce anything with the testcase from comment #2.
Sorry for the confusion. The code in comment #2 was here only to show the
actual code after the inlining of trisolve and to try to point to the loops
that were vectorized or not with/without -flto.
> Maybe you can reduce the testcase with this information?
Well, I'll try, but I won't have too much time for it in the coming weeks.
