    +If you're running on a linux system that supports the "binfmt_misc" +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):

    + +
    +   $ 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
+
    + +

    +This allows you to execute LLVM bytecode files directly. Thanks to Jack +Cummings for pointing this out! +
