This is the first model under 16B I try that could under stand stack manipulation

Simple IL code like this but every model I try could not understand it until your model (I try other Gemma4 heretic but also get wrong result)

.method static int subtract(int, int, int){ .maxstack 3 ldarg.2 ldarg.1 ldarg.0 sub sub ret }

And your model result is a correct way of thinking even if it's a bit confuse in conclusion.

Stack Manipulation:

  • Original: ldarg.2 ldarg.1 ldarg.0 sub sub ret
  • Load arg[2], Load arg[1], Load arg[0]. (Stack: [arg2, arg1, arg0])
    * sub: Pops two, pushes result (e.g., arg1 - arg0). (Stack: [arg2, result])
    * sub: Pops two, pushes result (e.g., arg2 - result). (Stack: [final_result])
    * ret: Returns.
    * Conclusion: This code calculates arg[2] - (arg[1] - arg[0]) or perhaps (arg[2] - arg[1]) - arg[0], depending on how sub is implemented when the operands are loaded sequentially. Given the context of a simple subtract method, it likely calculates arg[2] - arg[1] - arg[0] or arg[2] - arg[0] - arg[1].
