Hi,

could you please take care of the profile-mode bits too? Let's try to keep
the 3 modes in sync, I noticed only by chance.
Does **anyone** use profile mode?

It has no maintainers, few (if any) users, and is an ongoing maintenance burden.
For sure it's a burden. I have no personal objections to removing it, but as long as it remains in, the testsuite must be clean, as for everything else.

Paolo.


    I can take care of this, sure.

Personally I find this profile mode really interesting and would advise anyone using libstdc++ to give it a try. I think it worth the maintenance effort.

And today I even consider extending it for an other purpose. I am working on using the hint of the unordered insert or emplace_hint methods. We will have to document how we use it but I also want to use the profile mode to study if the iterator used as a hint has been really useful or not. That is part of the nice stuff the profile mode can do.
