Yup. As mentioned in my previous message.

Precisely. I think between Tom & Serge with direct upstream work and my contacts into the LLVM groups at IBM and ARM I'm confident we'll be able to deal with issues. Or to look at it another way. Red Hat's supported offerings already include full support for Clang/LLVM (using libstdc++, not libc++) and GCC. They have to work and they have to work together. Red Hat is already in a dual compiler world.
