Re: Lua versus Ravi versus Luajit - a simple benchmark

Hi,

This is another test. It is a modified version of the first fornum
test just to make things a bit more difficult.

local function x()
  local j = 0.0
  for i=2.0,1000000000.0 do
  j = i
  for k=3,5 do
  j = k
  end
  end
  return j
end

You can see the test programs, and generated LLVM IR at:
