The main mechanism for performing data layout queries.
Instances of this class can be created for an operation implementing DataLayoutOpInterface. Upon construction, a layout spec combining that of the given operation with all its ancestors will be computed and used to handle further requests. For efficiency, results to all requests will be cached in this object. Therefore, if the data layout spec for the scoping operation, or any of the enclosing operations, changes, the cache is no longer valid. The user is responsible creating a new DataLayout object after any spec change. In debug mode, the cache validity is being checked in every request.

| unsigned mlir::DataLayout::getStackAlignment | ( | ) | const |
Returns the natural alignment of the stack in bits.
Alignment promotion of stack variables should be limited to the natural stack alignment to prevent dynamic stack alignment. Returns zero if the stack alignment is unspecified.
