If you're running on a linux system that supports the "<a
href="http://www.tat.physik.uni-tuebingen.de/~rguenth/linux/binfmt_misc.html">binfmt_misc</a>"
module, and you have root access on the system, you can set your system up to
execute LLVM bytecode files directly. To do this, use commands like this (the
first command may not be required if you are already using the module):</p>
<pre>
$ mount -t binfmt_misc none /proc/sys/fs/binfmt_misc
$ echo ':llvm:M::llvm::/path/to/lli:' > /proc/sys/fs/binfmt_misc/register
$ chmod u+x hello.bc (if needed)
$ ./hello.bc
</pre>
<p>
This allows you to execute LLVM bytecode files directly. Thanks to Jack
Cummings for pointing this out!
