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.

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.
