Matthias Springer	c0a6318d96	[mlir][tensor] Add tensor.dim operation ... * Split memref.dim into two operations: memref.dim and tensor.dim. Both ops have the same builder interface and op argument names, so that they can be used with templates in patterns that apply to both tensors and memrefs (e.g., some patterns in Linalg). * Add constant materializer to TensorDialect (needed for folding in affine.apply etc.). * Remove some MemRefDialect dependencies, make some explicit.

Aart Bik	96a23911f6	[mlir][sparse] complete migration to sparse tensor type ... A very elaborate, but also very fun revision because all puzzle pieces are finally "falling in place". 1. replaces lingalg annotations + flags with proper sparse tensor types 2. add rigorous verification on sparse tensor type and sparse primitives 3. removes glue and clutter on opaque pointers in favor of sparse tensor types 4. migrates all tests to use sparse tensor types NOTE: next CL will remove *all* obsoleted sparse code in Linalg Reviewed By: bixia Differential Revision: https://reviews.llvm.org/D102095	2021-05-10 12:55:22 -07:00
Aart Bik	a2c9d4bb04	[mlir][sparse] Introduce proper sparsification passes ... This revision migrates more code from Linalg into the new permanent home of SparseTensor. It replaces the test passes with proper compiler passes. NOTE: the actual removal of the last glue and clutter in Linalg will follow Reviewed By: bixia Differential Revision: https://reviews.llvm.org/D101811	2021-05-04 17:10:09 -07:00
