Building Debian with LLVM/Clang
This proposal has been accepted as a session.
One Line Summary
Rebuilding Debian with Clang
Abstract
After extending Debian with two new kernels, Debian will soon be able to be built with a new free C, C++ and Objective-C compiler called Clang. Debian being one of the biggest distribution in term of number of packages (more than 18000), it represents an excellent test for a new key component like a compiler.
Based on LLVM, this compiler is now close to gcc on many different aspects (performances, build time, level of support of C and C++).
This talk will present the current status of a clang-build version of Debian, the different issues faced, the next steps and evolutions.
The rebuild shows that around 12% of the software packaged in Debian are failing because of programming mistakes. Fixing all of them would require a huge effort.
Therefor, how can we make clang more know to make upstream fix their issues ?
How can we make distributions collaborate on this aspect ?

Biography
Sylvestre Ledru has been involved in Debian for the last 6 years. He worked on various aspects of the distribution (scientific packages, Java, etc) and he is now focusing on rebuilding Debian with clang (a LLVM based compiler) instead of gcc.
Besides Debian, Sylvestre is working at IRILL, a research center about free software and on Scilab, a free numerical computing software.
