Detailed Description

Operation is the basic unit of execution within MLIR.

The following documentation are recommended to understand this class:

An Operation is defined first by its name, which is a unique string. The name is interpreted so that if it contains a '.' character, the part before is the dialect name this operation belongs to, and everything that follows is this operation name within the dialect.

An Operation defines zero or more SSA Value that we refer to as the Operation results. This array of Value is actually stored in memory before the Operation itself in reverse order. That is for an Operation with 3 results we allocate the following memory layout:

[Result2, Result1, Result0, Operation] ^ this is where Operation* pointer points to.

A consequence of this is that this class must be heap allocated, which is handled by the various create methods. Each result contains:

one pointer to the first use (see OpOperand)
the type of the SSA Value this result defines.
the index for this result in the array. The results are defined as subclass of ValueImpl, and more precisely as the only two subclasses of OpResultImpl: InlineOpResult and OutOfLineOpResult. The former is used for the first 5 results and the latter for the subsequent ones. They differ in how they store their index: the first 5 results only need 3 bits and thus are packed with the Type pointer, while the subsequent one have an extra unsigned value and thus need more space.

An Operation also has zero or more operands: these are uses of SSA Value, which can be the results of other operations or Block arguments. Each of these uses is an instance of OpOperand. This optional array is initially tail allocated with the operation class itself, but can be dynamically moved out-of-line in a dynamic allocation as needed.

An Operation may contain optionally one or multiple Regions, stored in a tail allocated array. Each Region is a list of Blocks. Each Block is itself a list of Operations. This structure is effectively forming a tree.

Some operations like branches also refer to other Block, in which case they would have an array of BlockOperand.

An Operation may contain optionally a "Properties" object: this is a pre-defined C++ object with a fixed size. This object is owned by the operation and deleted with the operation. It can be converted to an Attribute on demand, or loaded from an Attribute.

Finally an Operation also contain an optional DictionaryAttr, a Location, and a pointer to its parent Block (if any).

References clone(), and options.

◆ clone() [2/2]

Operation * Operation::clone	(	IRMapping &	mapper,
		CloneOptions	options = `CloneOptions::all()`
	)

Create a deep copy of this operation, remapping any operands that use values outside of the operation using the map that is provided (leaving them alone if no entry is present).

Replaces references to cloned sub-operations to the corresponding operation that is copied, and adds those mappings to the map. Optionally, one may configure what parts of the operation to clone using the options parameter.

Calling this method from multiple threads is generally safe if through the process of cloning no new uses of 'Value's from outside the operation are created. Cloning an isolated-from-above operation with no operands, such as top level function operations, is therefore always safe. Using the mapper, it is possible to avoid adding uses to outside operands by remapping them to 'Value's owned by the caller thread.

Replaces references to cloned sub-operations to the corresponding operation that is copied, and adds those mappings to the map.

◆ walk() [1/2]

std::enable_if_t<llvm::function_traits<std::decay_t<FnT> >::num_args == 1, RetT> mlir::Operation::walk ( FnT && callback )

inline

Walk the operation by calling the callback for each nested operation (including this one), block or region, depending on the callback provided.

The order in which regions, blocks and operations at the same nesting level are visited (e.g., lexicographical or reverse lexicographical order) is determined by 'Iterator'. The walk order for enclosing regions, blocks and operations with respect to their nested ones is specified by 'Order' (post-order by default). A callback on a block or operation is allowed to erase that block or operation if either:

the walk is in post-order, or
the walk is in pre-order and the walk is skipped after the erasure.

The callback method can take any of the following forms: void(Operation*) : Walk all operations opaquely.

op->walk([](Operation nestedOp) { ...}); void(OpT) : Walk all operations of the given derived type.
op->walk([](ReturnOp returnOp) { ...}); WalkResult(Operation|OpT) : Walk operations, but allow for interruption/skipping.
op->walk([](... op) { // Skip the walk of this op based on some invariant. if (some_invariant) return WalkResult::skip(); // Interrupt, i.e cancel, the walk based on some invariant. if (another_invariant) return WalkResult::interrupt(); return WalkResult::advance(); });

std::enable_if_t<llvm::function_traits<std::decay_t<FnT> >::num_args == 2, RetT> mlir::Operation::walk ( FnT && callback )

inline

Generic walker with a stage aware callback.

Walk the operation by calling the callback for each nested operation (including this one) N+1 times, where N is the number of regions attached to that operation.

The callback method can take any of the following forms: void(Operation *, const WalkStage &) : Walk all operation opaquely

op->walk([](Operation nestedOp, const WalkStage &stage) { ...}); void(OpT, const WalkStage &) : Walk all operations of the given derived type.
op->walk([](ReturnOp returnOp, const WalkStage &stage) { ...}); WalkResult(Operation|OpT, const WalkStage &stage) : Walk operations, but allow for interruption/skipping.
