# 'memref_ext' Dialect

extended memref dialect

## Operations

### `memref_ext.alloc_workspace` (::bishengir::memref_ext::AllocWorkspaceOp)

_Workspace memory allocation operation._

Syntax:

```mlir
operation ::= `memref_ext.alloc_workspace` `(`$dynamicSize`)` (`from` $workspaceArg^)? ( `offset` `=` `[`$offset^`]`)?
              attr-dict `:` (`from` type($workspaceArg)^ `to`)? type($memref)
```

The `alloc_workspace` operation allocates a region of workspace memory.
Example:

```mlir
memref_ext.alloc_workspace() : memref<100xi8>
memref_ext.alloc_workspace(%dynamic) : memref<2x?xi32>
memref_ext.alloc_workspace(%dynamic) from %arg offset = [%offset] : from memref<?xi8> to memref<2x?xi32>
```
