## Types

### PointerType

_Pointer type (`::mlir::triton::PointerType`) in Triton IR type system_

Pointer type in Triton IR type system. Pointer types may only point to scalar element types.

#### Parameters:

| Parameter | C++ type | Description |
| :-------: | :-------: | ----------- |
| pointeeType | `Type` |  |
| addressSpace | `PtrAddrSpace` |  |

### TensorDescType

_Tensor descriptor type (`::mlir::triton::TensorDescType`) in Triton IR type system_

A portable abstraction for TMA descriptors.
This is the base tensor descriptor type for tiled tensor memory access.

Shape and elementType describe the block dimensions and data type.
The optional sharedLayout attribute carries the shared memory encoding
(e.g. swizzle pattern) that is assigned during lowering.

For specialized access patterns like im2col, see TensorDescIm2ColType
in the TritonNvidiaGPU dialect.

#### Parameters:

| Parameter | C++ type | Description |
| :-------: | :-------: | ----------- |
| shape | `::llvm::ArrayRef<int64_t>` |  |
| elementType | `Type` |  |
| sharedLayout | `Attribute` |  |
