How to compile and test?

To generate a binary from an IA-32 assembly file:

add-ia32.tig

let
  function add(x: int, y: int) : int = x + y
in
  print_int(add(1,(add(2, 3)))); print("\n")
end

tc -e --target-ia32 --asm-compute --inst-display add-ia32.tig

$ tc -e --target-ia32 --asm-compute --inst-display add-ia32.tig
