Hello, I admit to be a fan of link time optimisation and would like to see this challenge promoted towards more of a routine challenge to establish for our packages. I found this informative thread
https://lists.debian.org/debian-devel/2011/06/msg00181.html that in particular sees the challenge for the buildds to cope with the additional demands on compute time and/or memory. With a couple of compiler versions down the road I still see no conceptional difference, except that possibly the build demons may have become more powerful compared with the average package size, especially so for the often embedded architectures. Spending most of my Debian time with scientific packages, I see a gain of speed on those routines as particularly rewarding. And this may also be a feature that would attract many to our platform as an extra advantage over the regular self-built or downloaded binary. Opinions? Steffen
