Jacques Pienaar ada0d41dbc [mlir][ods] Allow filtering of ops
Add option to filter which op the OpDefinitionsGen run on. This enables having multiple ops together in the same TD file but generating different CC files for them (useful if one wants to use multiclasses or split out 1 dialect into multiple different libraries). There is probably more general query here (e.g., split out all ops that don't have a verify method, or that are commutative) but filtering based on op name (e.g., test.a_op) seemed a reasonable start and didn't require inventing a query specification mechanism here.

AlexEichenberger 01641197ee [MLIR] Remove TableGen redundant calls to native calls when creating new operations in DRR TableGen files
Summary:
Currently, the TableGen rewrite generates redundant native calls in MLIR DRR files. This is a problem as some native calls may involve significant computations (e.g. when performing constant propagation where every values in a large tensor is touched).

The pattern was as follow:

```c++
if (native-call(args)) tblgen_attrs.emplace_back(rewriter, attribute, native-call(args))
```

The replacement pattern compute `native-call(args)` once and then use it both in the `if` condition and the `emplace_back` call.

This revision replaces MatmulOp, now that DRR rules have been dropped.
This revision also fixes minor parsing bugs and a plugs a few holes to get e2e paths working (e.g. library call emission).

During the replacement the i32 version had to be dropped because only the EDSC operators +, *, etc support type inference.

Deciding on a type-polymorphic behavior, and implementing it, is left for future work.

Jacques Pienaar b0921f68e1 [mlir] Add verify method to adaptor
This allows verifying op-indepent attributes (e.g., attributes that do not require the op to have been created) before constructing an operation. These include checking whether required attributes are defined or constraints on attributes (such as I32 attribute). This is not perfect (e.g., if one had a disjunctive constraint where one part relied on the op and the other doesn't, then this would not try and extract the op independent from the op dependent).

The next step is to move these out to a trait that could be verified earlier than in the generated method. The first use case is for inferring the return type while constructing the op. At that point you don't have an Operation yet and that ends up in one having to duplicate the same checks, e.g., verify that attribute A is defined before querying A in shape function which requires that duplication. Instead this allows one to invoke a method to verify all the traits and, if this is checked first during verification, then all other traits could use attributes knowing they have been verified.

It is a little bit funny to have these on the adaptor, but I see the adaptor as a place to collect information about the op before the op is constructed (e.g., avoiding stringly typed accessors, verifying what is possible to verify before the op is constructed) while being cheap to use even with constructed op (so layer of indirection between the op constructed/being constructed). And from that point of view it made sense to me.

Wen-Heng (Jack) Chung 2fd6403a6d [mlir][gpu] Introduce mlir-rocm-runner.
Summary:
`mlir-rocm-runner` is introduced in this commit to execute GPU modules on ROCm
platform. A small wrapper to encapsulate ROCm's HIP runtime API is also inside
the commit.

Due to behavior of ROCm, raw pointers inside memrefs passed to `gpu.launch`
must be modified on the host side to properly capture the pointer values
addressable on the GPU.

LLVM MC is used to assemble AMD GCN ISA coming out from
`ConvertGPUKernelToBlobPass` to binary form, and LLD is used to produce a shared
ELF object which could be loaded by ROCm HIP runtime.

gfx900 is the default target be used right now, although it could be altered via
an option in `mlir-rocm-runner`. Future revisions may consider using ROCm Agent
Enumerator to detect the right target on the system.

Notice AMDGPU Code Object V2 is used in this revision. Future enhancements may
upgrade to AMDGPU Code Object V3.

Bitcode libraries in ROCm-Device-Libs, which implements math routines exposed in
`rocdl` dialect are not yet linked, and is left as a TODO in the logic.

Nicolas Vasilache 5f9e0466f2 [mlir][Vector] Fix vector.transfer alignment calculation
https://reviews.llvm.org/D79246 introduces alignment propagation for vector transfer operations. Unfortunately, the alignment calculation is incorrect and can result in crashes.

This revision fixes the calculation by using the natural alignment of the memref elemental type, instead of the resulting vector type.

If more alignment is desired, it can be done in 2 ways:
1. use a proper vector.type_cast to transform a memref<axbxcxdxf32> into a memref<axbxvector<cxdxf32>> giving a natural alignment of vector<cxdxf32>
2. add an alignment attribute to vector transfer operations and propagate it.

With this change the alignment in the relevant tests goes down from 128 to 4.

Lastly, a few minor cleanups are performed and the custom `isMinorIdentityMap` is deprecated.

Jacques Pienaar 4b8632e174 [mlir] Expand operand adapter to take attributes
* Enables using with more variadic sized operands;
* Generate convenience accessors for attributes;
  - The accessor are named the same as their name in ODS and returns attribute
    type (not convenience type) and no derived attributes.

This is first step to changing adapter to support verifying argument
constraints before the op is even created. This does not change the name of
adaptor nor does it require it except for ops with variadic operands to keep this change smaller.

Considered creating separate adapter but decided against that given operands also require attributes in general (and definitely for verification of operands and attributes).

Lei Zhang a4441fcd12 [mlir][vulkan-runner] Avoid dependency on LLVM libraries
The Vulkan runtime wrapper will be compiled to a shared library
that are loaded by the JIT runner. Depending on LLVM libraries
means that LLVM symbols will be compiled into the shared library.
That can cause problems if we are using it with other shared
libraries depending on LLVM, notably Mesa, the open-source graphics
driver framework. The Vulkan API wrappers invoked by the JIT runner
links to the system libvulkan.so. If it's Mesa providing the
implementation, Mesa will normally try to load the system libLLVM.so
for its shader compilation. That causes issues because the JIT runner
already loaded the Vulkan runtime wrapper which has LLVM sybmols
compiled in. So system linker will instruct Mesa to use those symbols
instead.

Jacques Pienaar 5eae715a31 [mlir] Add NamedAttrList
This is a wrapper around vector of NamedAttributes that keeps track of whether sorted and does some minimal effort to remain sorted (doing more, e.g., appending attributes in sorted order, could be done in follow up). It contains whether sorted and if a DictionaryAttr is queried, it caches the returned DictionaryAttr along with whether sorted.

Change MutableDictionaryAttr to always return a non-null Attribute even when empty (reserve null cases for errors). To this end change the getter to take a context as input so that the empty DictionaryAttr could be queried. Also create one instance of the empty dictionary attribute that could be reused without needing to lock context etc.

Update infer type op interface to use DictionaryAttr and use NamedAttrList to avoid incurring multiple conversion costs.

Stephen Neuendorffer c296d2dc53 [MLIR] mlir-opt needs PUBLIC dependence
We see intermittent build errors on the windows buildbot because
mlir-opt is including Linalg headers which haven't been built yet.
This dependence should be resolved by declaring a PUBLIC dependence
on the Linalg library when building MLIROptMain.

Andy Davis 93d1108801 [MLIR][LoopOps] Adds the loop unroll transformation for loop::ForOp.
Summary:
Adds the loop unroll transformation for loop::ForOp.
Adds support for promoting the body of single-iteration loop::ForOps into its containing block.
Adds check tests for loop::ForOps with dynamic and static lower/upper bounds and step.
Care was taken to share code (where possible) with the AffineForOp unroll transformation to ease maintenance and potential future transition to a LoopLike construct on which loop transformations for different loop types can implemented.
