One: Compile FE: CUSTOM(MatMul) to FC+TRANSPOSE

[seanshpark]

Latest (TF 2.2) version TF lite converter converts MatMul Op to FULLY_CONNECTED + TRANSPOSE.
But, old version drops it as CUSTOM(MatMul).

We may need to add a Pass to do this if our import reads this Op.

Do you mean CUSTOM(MatMul) to FULLY_CONNECTED conversion?
I also want to point, that latest TF is not able to convert all variants of MatMul operator.
For example, we still can get custom op for tf.linalg.matmul(x, y, transpose_a=True, transpose_b=False)

Yes..

Yes, not all but it is good if we can convert any possible cases.
