Are we going to cut off all the GNU compiler tool > chains and use the llvm/clang when it's mature. there is no official stand on this but I guess the framework to enable optional usage of clang as "cc" instead of gcc might be committed "soon"... but that does not switch anything. there's quite a lot of work still to do (on both fbsd and clang/llvm side). things have stalled a little recently - it's summer, people got distracted, code freeze etc. but at least I am going to push some more work on this after the freeze/summer... this is my personal view not representing anything official in FreeBSD roman
