The debug-mode bits are now in. It would be nice to have the profile-mode bits
too for 4.6.0...

Hello Paolo,

Thank you for the notification.  It's *much* easier to use debug mode as a
template than to start from scratch.

What is the time frame for 4.6.0?

For reference, what needs to be done at this point is a couple of new
diagnostics
1. "forward_list to vector": if the only operations are "insert_after last
element" and iteration, and if the size is always about the same.
2. "forward_list to deque": this needs a cost model.

Paolo, would it make sense to open tickets for other diagnostics as well,
even if it would take me a while to close them?  Maybe some student out
there will pick them if they're well defined.

Thank you,
Silvius

We are still in Stage 1, but I don't have many details at the moment, I would
suggest simply following the various announcements on the gcc mailing list.

Ok...

If you ask me, normally we don't open many PRs for pure enhancement issues, the
situation can quickly grow without control. After all, Bugzilla is for *bugs*.
Thus I would recommend summarizing those issues to a minimal number of PRs,
better if each has a student already "assigned", somehow.

Silvius --

due to the recent changes to the normal-mode forward_list to enable the
debug-mode version (essentially the use of a nested namespace), now simply
including <forward_list> as part of a profile-mode build breaks everything.
Just run make check-profile to see what I mean. I can add a dummy profile-mode
forward_list, not profiling anything, just let me know if you actually mean to
implement something beyond that. Thanks.

I'm not able to get in contact with Silvius. Thus I'm adding a dummy
profile-mode forward_list myself, and hoping for substantive work from the
contributors of profile-mode in the future (by the way, the situation with
<bitset> seems quite similar).

I'm looking for help for the profile-mode version (I'm going to take care of
the debug-mode one)

Hello Paolo,

Could you please assign it to me.  (Also feel free to assign any other
unclaimed profile mode bugs to me, current or future.)

Thank you,
Silvius

------- Comment #2 from rus at google dot com  2010-05-03 22:46 -------
It's not clear from the description what the problem is here.  The profile mode
doesn't instrument either forward_list or slist at this point, so all
inclusions of <forward_list> should fall back to normal mode.

Could you please clarify the problem?

Silvius, this is not a bug proper, instead an *enhancement* request: it seems
quite obvious to me, if only for consistency, that we want to provide
debug-mode and profile-mode versions of forward_list too, like all the other
containers, no?!?

Oh, OK.  I misunderstood.  Then let's keep it open to track the addition of new
modules including forward_list.

------- Comment #5 from paolo dot carlini at oracle dot com  2010-05-03 23:16 -------
Yes ;) I'm going to work asap on debug-mode, certainly we want it too for
4.6.0, but it's a bit tricky because of the special way many operations are
specified in terms of the *preceding* element: debug-mode is missing a bit of
infrastructure for that.
