[mlir][Ptr] Init the Ptr dialect with the `!ptr.ptr` type. (#86860) 2024-06-27T12:14:34+00:00 Fabian Mora fmora.dev@gmail.com 2024-06-27T12:14:34+00:00 e035ef0e7423c1a4c78e922508da817dbd5b6a02 This patch initializes the `ptr` dialect directories and base files, adding the `!ptr.ptr` type and the `#ptr.spec<...>` data layout spec attribute. The `!ptr.ptr` type is an opaque pointer type optionally parameterized by a memory space. This type typically represents a handle to an object in memory or target-dependent values like `nullptr`. The implementation of the `DataLayoutTypeInterface` interface for `!ptr.ptr` was adapted from `!llvm.ptr`'s implementation. This implementation uses the `#ptr.spec<...>` attribute for defining the data layout specification. See [[RFC] `ptr` dialect & modularizing ptr ops in the LLVM dialect](https://discourse.llvm.org/t/rfc-ptr-dialect-modularizing-ptr-ops-in-the-llvm-dialect/75142) for rationale and roadmap.
