You will find all the patches and hacks to build FreeBSD with llvm/clang trunk here: http://llvm-amd64.freebsd.your.org/patches/ clang-*.diff contains the FreeBSD local changes, -fformat-extensions and worldtmp prefix stuff. freebsd-*.diff contains the patches for FreeBSD to fix/disable -Werror warnings found by clang trunk and needed hacks to the build infrastructure to use an out-of-tree compiler.
