Hey Andrew,
Thanks for sharing your progress.
Sadly I can't get your branch to build

````
Also looking at the example output provided, I see [sid_2 being
allocated](https://github.com/areusch/incubator-tvm/blob/aot-experiment/sample-output.txt#L125)
but never being used.
I have a question about the return values of the function calls.
More specifically, the output of
[`fused_layout_transform_2`](https://github.com/areusch/incubator-tvm/blob/aot-experiment/sample-output.txt#L139).
Is the return tensor
[`values[1]`](https://github.com/areusch/incubator-tvm/blob/aot-experiment/sample-output.txt#L130)
or is it
[`subcall_ret_value`](https://github.com/areusch/incubator-tvm/blob/aot-experiment/sample-output.txt#L136)?
* seeing line
[156](https://github.com/areusch/incubator-tvm/blob/aot-experiment/sample-output.txt#L156),
I would say its in `values[1]`, but then what is `subcall_ret_value`?
Again thanks for showing some of the progress :)
