[mlir] Remove unused includes (NFC) (#148119) 2025-07-11T18:59:26+00:00 Kazu Hirata kazu@google.com 2025-07-11T18:59:26+00:00 5e0de68626828009c4cc09e2ce984f9c9634f6f6 These are identified by misc-include-cleaner. I've filtered out those that break builds. Also, I'm staying away from llvm-config.h, config.h, and Compiler.h, which likely cause platform- or compiler-specific build failures.

 [mlir][Tensor] Move concat operation decomposition as a method of the concat operation. (#116004) 2024-11-13T21:29:04+00:00 MaheshRavishankar 1663364+MaheshRavishankar@users.noreply.github.com 2024-11-13T21:29:04+00:00 de6d48d05d7aa233248d2f725654931cb1e2f6fd Currently the implementation is within a pattern that cannot be used without a pattern rewriter. Move the decomposition as a method of the operation to make it usable outside of pattern rewrites. Signed-off-by: MaheshRavishankar <mahesh.ravishankar@gmail.com>

 [mlir] Use `create` instead of `createOrFold` for ConstantOp as folding has no effect (NFC) (#80129) 2024-02-01T07:40:37+00:00 Hugo Trachino 32955781+nujaa@users.noreply.github.com 2024-02-01T07:40:37+00:00 65066c02770cc3da3b5154fbb7ed9df78ab94b93 This aims to clean-up confusing uses of builder.createOrFold<ConstantOp> since folding of constants fails.

 [mlir][tensor] Add a tensor.concat operation (#72779) 2023-12-01T20:05:29+00:00 Quinn Dawkins quinn.dawkins@gmail.com 2023-12-01T20:05:29+00:00 f310a5d2c13455f1d68f5654fa4258357bafeff6 This adds an operation for concatenating ranked tensors along a static dimension, as well as a decomposition mirroring the existing lowering from TOSA to Tensor. This offers a convergence point for "input" like dialects that include various lowerings for concatenation operations, easing later analysis. In the future, this op can implement the necessary interfaces for tiling, as well as potentially add conversions to some kind of linalg and/or memref counterpart. This patch adds the op, the decomposition, and some basic folding/canonicalization. Replacing lowerings with the op (such as the TOSA lowering) will come as a follow up. See https://discourse.llvm.org/t/rfc-tensor-add-a-tensor-concatenate-operation/74858
