A mailing list for architectural changes?

[Sean McNeil <sean at mcneil dot com>]

Hello all,

The gcc mailing list is way too busy for me to keep an eye on and would
cause me to get sucked in to reading a whole lot of interesting, yet
time-consuming, discussions.

Is there or should there be a mailing list that just deals with
architectural changes made in gcc?  For instance, I just got stung by a
change made to the way multilibs are determined.  Before,
multilib_matches_raw wasn't necessarily required to have a switch
specified in it's array in order for it to be used in multilib_raw. 
Now, it has to be or the multilib will not be correctly identified.

It sure would have saved me a lot of time if I had seen some kind of
notification that this behavior had changed.  If there isn't anything in
place for such discussion/notification, then I would like to propose a
list be created for this.

The whole -fobey-inline discussion is a case-in-point.  Although I have
found this an interesting topic, it would be nice to have a clean area
that gets a notification that the behavior of inlining is about to
change or has changed in some manner (along with a description of the
change).

Sincerely,
Sean
