No, I actually read the article and I don't think I was spectacularly rude. I was rather just straight to the point. And rather than bitching "omg, why, oh why did a compiler turn a ctr into a function-call here?!" what I think I gave is a constructive suggestion how to fix the problem, if there was even one to begin with.

What I see here in the article is pure theoreticizing and dwelling over details which in 99.9% of the cases do _not_ matter. There wasn't a single experiment shown by the author by which he shows that his use-case is in that 0.01%.

I was basically done with reading the article when I read the following nonsense

> accessing an extern thread_local with a constructor involves a function call, with the function testing the guard variable of the translation unit where the thread_local is defined.

And then

> But with inlining, the fast path is quite fast on a good processor.

Right, the fast path of inlined ctr call vs slow path of non-inlined ctr call. Really? I call this a BS, especially without the experiments showing the data.



Maybe you should write your own blog post that counters the author’s so that others can learn from your experience.


I have no such aspirations. Commenting here when I have time and to learn something and not to prove something to somebody else.
