We generate actual_data_name and data_length_var_name in the inputs/outputs already, why are we recalculating it here based on types we've defined within the AOT test harness?
We probably need to add a _LEN macro to the MLF header?

As discussed offline, the two variables LEN and SIZE serve different purposes. SIZE will come from MLF export whereas LEN will be part of the AOT test harness.

@Mousius could you please take a look again after the LEN was included from AOT test harness? |

Given we know the model_name can we not just look for tvmgen_{model_name}.h rather than looping?

Can we also do this for the input sizes?

I will extend the check for inputs. We could directly look for the file, but I thought that check maynot work for multiple models. But it does, so I will update that too.

I assume this just requires looking for both headers?

Oh, there is just one header in those cases too. Both models' sizes appear in a single header. So, need not be tested additionally.

That sounds wrong, shouldn't there be a tvmgen_model1.h and a tvmgen_model2.h ?

My bad. I confused this with the multi-model test which it is not. In case of multi model test, I do see two separate headers being produced.

We should probably check the _SIZE values match with the appropriate constants rather than them just appearing in the same file together?

I tried doing that initially. Any short cuts to do that?

Something like:
assert contents.count("_SIZE") == 4
assert f"INPUT_1_SIZE {ref_output_size}" in contents
?

Ah ok. I misunderstood what you were asking for. This makes sense. Thanks for the help.
