Nope, because you can't just ship a full list of packages for a full list of processors on the given architecture. You can build your world/packages though adding -march=native to CFLAGS. > 10.

No, LLVM is rather a backend with a lot of copmiler and toolchain stuff. There's a Java/.NET rewrite using LLVM named vmkit and I think JVM there is almost functional. But it's not even in the ports. -- Sphinx of black quartz, judge my vow.
