Actually, if you run the loop from 9999 down to 0, you can get down to 3
instructions per loop:
->LOOP:
7ffc840dff80 addsd xmm7, [rax+rdi*8+0x8]
7ffc840dff86 add edi, -0x01
7ffc840dff89 jge 0x7ffc840dff80 ->LOOP
Also, the way you want to compile a lua script into an executable is
impossible with LuaJIT, it's a tracing JIT, which means it only compiles
parts of the code which is executed frequently, the rest is interpreted.
