In torch.index_put like ops, `values` is only required to be
broadcastable to `input[indices]`, rather than exact dimension match.
This patch fixes the problem by add additional
stablehlo.dynamic_broadcast_in_dim before creating stablehlo.scatter op.
BTW, this patch also enhance the `getBroadcastResultShape` utility in
hlo namespace.
Discovered in https://github.com/llvm/torch-mlir/issues/3104
Most likely when building with stablehlo, while waiting for it missing
dependency was generated to location shared with another dependency.
This commit extends the OnnxToTorch lowering for BatchNormalization op
for supporting the case when training=True.

The `layout` attribute was not considered for the `onnx.RNN` operation.
Added support for the attribute to transpose the inputs / outputs of the
RNN when valid.
The einsum lowering was missing the behavior for duplicate indices in
the equation. This amounts to a diagonalization along duplicate pairs of
indices in the equation.
Closes#3575
The PyTorch remainder operator is meant to compute the Python modulus
operator entrywise:
https://pytorch.org/docs/stable/generated/torch.remainder.html#torch.remainder
In python the modulus operator is meant to always return a result with
the same sign as the divisor:
https://docs.python.org/3/reference/expressions.html#binary-arithmetic-operations
In other words, torch.aten.remainder should return a Python-style
modulus instead of a C-style modulus. However the remainder operator was
simply translated into arith.ModSI or arith.ModF, which both effectively
compute the C-style modulus. Now the lowering has been modified so that
the modulus operator works properly with negative numbers, both in the
dividend, and the divisor.
This adds the `generate-runtime-verification` pass into the linalg
refbackend, and moves all tests that now abort at runtime into the crash
set, sorted by their respective errors.
I have fixed on set of errors found that way, which are mismatches
between the static dimensions we cast to and the actual dynamic
dimensions. This was caused by wrong annotations on the test cases, like
in
https://github.com/llvm/torch-mlir/pull/3615/files#diff-48bfbf41fcad5fa01b49197d251114f84a2b8de4f1d87ab938a061aedd1419b1R1931
This patch adds basic support for lowering graphs with per-channel
quantization. Per-channel quantized ops have to be excluded from
`FuseQuantizedOps` for now but can be used in QDQ quantized form.
Using this patch, we're able to import and execute (on the linalg
backend) graphs with per-channel quantization applied using the "new"
PyTorch 2.0 Export Quantization.
The saga of aligning onnx and torch padding conventions continues.
```python
onnx_pads = [low_x, low_y, low_z, high_x, high_y, high_z]
torch_pads = [low_z, high_z, low_y, high_y, low_x, high_x]
```
So not only is the lexicographical ordering hierarchy swapped (low/high
x spatial-dim -> spatial-dim x low/high) but the ordering in the the
spatial-dim specification is also reversed.
This patch properly reverses the pad ordering (and actually uses the
`shuffledPadding` to pad).
The pattern `m_OnnxListOfConstantInts` previously only checked if the
attr inside an `onnx.Constant` op is a `DenseResourceElementsAttr`, but
didn't handle `ElementsAttr`'s. This patch adds support for
`ElementsAttr` and provides an example of it's use via a lit test for
`onnx.Unsqueeze`.
