<ul>
<li>
The JIT compiler can only generate code for CPUs with <b>SSE2</b> at the
moment. I.e. you need at least a P4, Core 2/i5/i7 or K8/K10 to use it. I
plan to fix this during the beta phase and add support for emitting x87
instructions to the backend.
The JIT compiler only generates code for CPUs with support for
<b>SSE2</b> instructions. I.e. you need at least a P4, Core 2/i5/i7
or K8/K10 to get the full benefit.<br>
If you run LuaJIT on older CPUs without SSE2 support, the JIT compiler
is disabled and the VM falls back to the interpreter.
Run the command line executable without arguments to show the current status
(<tt>JIT: ON</tt> or <tt>JIT: OFF</tt>).

Obviously there will be many <b>bugs</b> in a VM which has been
