[mlir][linalg] Extend linalg.pack and linalg.unpack to accept memref (#167675)
Extend linalg.pack and linalg.unpack to accept memref operands in
addition to tensors. As part of this change, we now disable all
transformations when these ops have memref semantics.

Closes https://github.com/llvm/llvm-project/issues/129004

[mlir][linalg] Reject unsigned pooling on non-integer element types (#166070)
Fixes: #164800 

Ensures unsigned pooling ops in Linalg stay in the integer domain: the
lowering now rejects floating/bool inputs with a clear diagnostic, new
regression tests lock in both the error path and a valid integer
example, and transform decompositions are updated to reflect the integer
typing.

[MLIR][Linalg] Remove matmul_transpose variants (#147961)
Removes the `(batch_)matmul_transpose_{a|b}` variants from OpDSL and
replace it with `matmul affine_maps [...]` whenever appropriate. This is
in line with the
[plan](https://discourse.llvm.org/t/rfc-op-explosion-in-linalg/82863),
and can be done since #104783 merged.

See:
https://discourse.llvm.org/t/deprecate-batch-matmul-transpose-a-b-linalg-operations/87245

Issues investigated:
* pad transform tests that could use `matmul` instead, so change to
that.
* ArmSME test using transpose actually needed it, so changed to `matmul`
+ affine maps.

Arm tests validated by @banach-space (thanks!!).

* Changing `linalg.elemwise_{u|bi}nary` with `linalg.{exp|add}` on
transform tests
* Changing some of the tests with `linalg.elementwise` instead, to

[MLIR][Linalg] Introduce transpose/broadcast semantic to linalg.batch… (#130944)
…_reduce_matmul.

This patch exposes broadcast and transpose semantics on
'batch_reduce_matmul'. This is the last one in continuation of other two
variant of matmul ops.

The broadcast and transpose semantic are as follows:

Broadcast and Transpose semantics can be appiled by specifying the
explicit attribute 'indexing_maps' as shown below. This is a list
attribute, so must include maps for all arguments if specified.

    Example Transpose:
    ```
    linalg.batch_reduce_matmul indexing_maps = [
       affine_map<(d0, d1, d2, d3) -> (d0, d3, d1)>, // transpose
       affine_map<(d0, d1, d2, d3) -> (d0, d3, d2)>,
       affine_map<(d0, d1, d2, d3) -> (d1, d2)>
       ]
          ins(%arg0, %arg1 : memref<2x5x3xf32>,memref<2x5x7xf32>)
          outs(%arg2: memref<3x7xf32>)
    ```

    Example Broadcast:
    ```
    linalg.batch_reduce_matmul indexing_maps = [
       affine_map<(d0, d1, d2, d3) -> (d3)>,         // broadcast
       affine_map<(d0, d1, d2, d3) -> (d0, d3, d2)>,
       affine_map<(d0, d1, d2, d3) -> (d1, d2)>
       ]
          ins(%arg0, %arg1 : memref<5xf32>, memref<2x5x7xf32>)
          outs(%arg2: memref<3x7xf32>)
    ```

    Example Broadcast and Transpose:
    ```
    linalg.batch_reduce_matmul indexing_maps = [
       affine_map<(d0, d1, d2, d3) -> (d1, d3)>,     // broadcast
       affine_map<(d0, d1, d2, d3) -> (d0, d2, d3)>, // transpose
       affine_map<(d0, d1, d2, d3) -> (d1, d2)>
       ]
          ins(%arg0, %arg1 : memref<3x5xf32>, memref<2x7x5xf32>)
          outs(%arg2: memref<3x7xf32>)
    ```

[MLIR][Linalg] Expose linalg.matmul and linalg.contract via Python API (#126377)
Now that linalg.matmul is in tablegen, "hand write" the Python wrapper
that OpDSL used to derive. Similarly, add a Python wrapper for the new
linalg.contract op.

Required following misc. fixes:
1) make linalg.matmul's parsing and printing consistent w.r.t. whether
indexing_maps occurs before or after operands, i.e. per the tests cases
it comes _before_.
2) tablegen for linalg.contract did not state it accepted an optional
cast attr.
3) In ODS's C++-generating code, expand partial support for `$_builder`
access in `Attr::defaultValue` to full support. This enables access to
the current `MlirContext` when constructing the default value (as is
required when the default value consists of affine maps).

[mlir][linalg] Introduce transpose semantic to 'linalg.matmul' ops. (#104783)
The main goal of this patch is to extend the semantic of 'linalg.matmul'
named op to include per operand transpose semantic while also laying out
a way to move ops definition from OpDSL to tablegen. Hence, it is
implemented in tablegen. Transpose semantic is as follows.

By default 'linalg.matmul' behavior will remain as is. Transpose
semantics can be appiled on per input operand by specifying the optional
permutation attributes (namely 'permutationA' for 1st input and
'permutationB' for 2nd input) for each operand explicitly as needed. By
default, no transpose is mandated for any of the input operand.

    Example:
    ```
%val = linalg.matmul ins(%arg0, %arg1 : memref<5x3xf32>,
memref<5x7xf32>)
              outs(%arg2: memref<3x7xf32>)
              permutationA = [1, 0]
              permutationB = [0, 1]
    ```

[MLIR][Python] enhance python api for tensor.empty (#103087)
Since we have extended `EmptyOp`, maybe we should also provide a
corresponding `tensor.empty` method. In the downstream usage, I tend to
use APIs with all lowercase letters to create ops, so having a
`tensor.empty` to replace the extended `tensor.EmptyOp` would keep my
code style consistent.

[mlir][linalg] regionBuilder for transpose, broadcast (#69742)
Currently, `linalg.transpose` and `linalg.broadcast` can't be emitted
through either the C API or the python bindings (which of course go
through the C API). See
https://discourse.llvm.org/t/how-to-build-linalg-transposeop-in-mlir-pybind/73989/10.

The reason is even though they're named ops, there is no opdsl
`@linalg_structured_op` for them and thus while they can be instantiated
they cannot be passed to
[`mlirLinalgFillBuiltinNamedOpRegion`](a7cccb9cbb/mlir/lib/CAPI/Dialect/Linalg.cpp (L18)).
I believe the issue is they both take a `IndexAttrDef` but
`IndexAttrDef` cannot represent dynamic rank. Note, if I'm mistaken and
there is a way to write the `@linalg_structured_op` let me know.

The solution here simply implements the `regionBuilder` interface which
is then picked up by
[`LinalgDialect::addNamedOpBuilders`](7557530f42/mlir/lib/Dialect/Linalg/IR/LinalgDialect.cpp (L116)).

Extension classes are added "by hand" that mirror the API of the
`@linalg_structured_op`s. Note, the extension classes are added to to
`dialects/linalg/__init__.py` instead of
`dialects/linalg/opdsl/ops/core_named_ops.py` in order that they're not
confused for opdsl generators/emitters.

363b655920 Finish renaming getOperandSegmentSizeAttr() from operand_segment_sizes to operandSegmentSizes
This renaming started with the native ODS support for properties, this is completing it.

A mass automated textual rename seems safe for most codebases.
Drop also the ods prefix to keep the accessors the same as they were before
this change:
 properties.odsOperandSegmentSizes
reverts back to:
 properties.operandSegementSizes

The ODS prefix was creating divergence between all the places and make it harder to
be consistent.

we made FuncOp an operation (years ago). This commit handles the
functional aspects of the move, but various aspects are left untouched
to ease migration: func::FuncOp is re-exported into mlir to reduce
the actual API churn, the assembly format still accepts the unqualified
`func`. These temporary measures will remain for a little while to

7294be2b8e [mlir][linalg] Replace linalg.fill by OpDSL variant.
The revision removes the linalg.fill operation and renames the OpDSL generated linalg.fill_tensor operation to replace it. After the change, all named structured operations are defined via OpDSL and there are no handwritten operations left.

A side-effect of the change is that the pretty printed form changes from:
```
%1 = linalg.fill(%cst, %0) : f32, tensor<?x?xf32> -> tensor<?x?xf32>
```
changes to
```
%1 = linalg.fill ins(%cst : f32) outs(%0 : tensor<?x?xf32>) -> tensor<?x?xf32>
```
Additionally, the builder signature now takes input and output value ranges as it is the case for all other OpDSL operations:
```
rewriter.create<linalg::FillOp>(loc, val, output)
```
changes to
```
rewriter.create<linalg::FillOp>(loc, ValueRange{val}, ValueRange{output})
```
All other changes remain minimal. In particular, the canonicalization patterns are the same and the `value()`, `output()`, and `result()` methods are now implemented by the FillOpInterface.

This revision is a preparation step to replace linalg.fill by its OpDSL counterpart linalg.fill_tensor. The two are only functionally equivalent if both specify the same canonicalization patterns. The revision is thus a prerequisite for the linalg.fill replacement.

23aa5a7446 [mlir] Rename the Standard dialect to the Func dialect
The last remaining operations in the standard dialect all revolve around
FuncOp/function related constructs. This patch simply handles the initial
renaming (which by itself is already huge), but there are a large number
of cleanups unlocked/necessary afterwards:

* Removing a bunch of unnecessary dependencies on Func
* Cleaning up the From/ToStandard conversion passes
* Preparing for the move of FuncOp to the Func dialect

e9085d0d25 [mlir][OpDSL] Rename function to make signedness explicit (NFC).
The revision renames the following OpDSL functions:
```
TypeFn.cast -> TypeFn.cast_signed
BinaryFn.min -> BinaryFn.min_signed
BinaryFn.max -> BinaryFn.max_signed
```
The corresponding enum values on the C++ side are renamed accordingly:
```
#linalg.type_fn<cast> -> #linalg.type_fn<cast_signed>
#linalg.binary_fn<min> -> #linalg.binary_fn<min_signed>
#linalg.binary_fn<max> -> #linalg.binary_fn<max_signed>

24357fec8d [mlir][OpDSL] Add arithmetic function attributes.
The revision extends OpDSL with unary and binary function attributes. A function attribute, makes the operations used in the body of a structured operation configurable. For example, a pooling operation may take an aggregation function attribute that specifies if the op shall implement a min or a max pooling. The goal of this revision is to define less and more flexible operations.

We may thus for example define an element wise op:
```
linalg.elem(lhs, rhs, outs=[out], op=BinaryFn.mul)
```
If the op argument is not set the default operation is used.

4d4cb17da8 [mlir][OpDSL] Refactor function handling.
Prepare the OpDSL function handling to introduce more function classes. A follow up commit will split ArithFn into UnaryFn and BinaryFn. This revision prepares the split by adding a function kind enum to handle different function types using a single class on the various levels of the stack (for example, there is now one TensorFn and one ScalarFn).

51fdd802c7 [mlir][OpDSL] Add type function attributes.
Previously, OpDSL operation used hardcoded type conversion operations (cast or cast_unsigned). Supporting signed and unsigned casts thus meant implementing two different operations. Type function attributes allow us to define a single operation that has a cast type function attribute which at operation instantiation time may be set to cast or cast_unsigned. We may for example, defina a matmul operation with a cast argument:

```
@linalg_structured_op
def matmul(A=TensorDef(T1, S.M, S.K), B=TensorDef(T2, S.K, S.N), C=TensorDef(U, S.M, S.N, output=True),
    cast=TypeFnAttrDef(default=TypeFn.cast)):
  C[D.m, D.n] += cast(U, A[D.m, D.k]) * cast(U, B[D.k, D.n])
```

When instantiating the operation the attribute may be set to the desired cast function:

```
linalg.matmul(lhs, rhs, outs=[out], cast=TypeFn.cast_unsigned)
```

The revsion introduces a enum in the Linalg dialect that maps one-by-one to the type functions defined by OpDSL.

d50571ab07 [mlir][OpDSL] Add default value to index attributes.
Index attributes had no default value, which means the attribute values had to be set on the operation. This revision adds a default parameter to `IndexAttrDef`. After the change, every index attribute has to define a default value. For example, we may define the following strides attribute:
```

```
When using the operation the default stride is used if the strides attribute is not set. The mechanism is implemented using `DefaultValuedAttr`.

Additionally, the revision uses the naming index attribute instead of attribute more consistently, which is a preparation for follow up revisions that will introduce function attributes.

a3655de2c8 [mlir][OpDSL] Add support for basic rank polymorphism.
Previously, OpDSL did not support rank polymorphism, which required a separate implementation of linalg.fill. This revision extends OpDSL to support rank polymorphism for a limited class of operations that access only scalars and tensors of rank zero. At operation instantiation time, it scales these scalar computations to multi-dimensional pointwise computations by replacing the empty indexing maps with identity index maps. The revision does not change the DSL itself, instead it adapts the Python emitter and the YAML generator to generate different indexing maps and and iterators depending on the rank of the first output.

Additionally, the revision introduces a `linalg.fill_tensor` operation that in a future revision shall replace the current handwritten `linalg.fill` operation. `linalg.fill_tensor` is thus only temporarily available and will be renamed to `linalg.fill`.

e3b442b62f [mlir][OpDSL] Separate ReduceFn and ReduceFnUse.
The revision distinguishes `ReduceFn` and `ReduceFnUse`. The latter has the reduction dimensions attached while the former specifies the arithmetic function only. This separation allows us to adapt the reduction syntax a little bit and specify the reduction dimensions using square brackets (in contrast to the round brackets used for the values to reduce). It als is a preparation to add reduction function attributes to OpDSL. A reduction function attribute shall only specify the arithmetic function and not the reduction dimensions.

Example:
```
ReduceFn.max_unsigned(D.kh, D.kw)(...)
```
changes to:
```
ReduceFn.max_unsigned[D.kh, D.kw](...)
```
