It only fixes Xen, not tools &c, and only 64-bit, so far. Building Xen with clang isn't useful in itself (and indeed produces a hypervisor that can be up to 10% slower for a default -O2 build); rather it's a stepping-stone to doing full link-time optimizations on the LLVM bitcode of the whole hypervisor. I will post a second series to enable that, but it's not so clean as this one. I think all the changes in this series are reasonable and won't inconvenience any normal users, but obviously they're meant for the xen-unstable tree only. Cheers, Tim.
