Member Function Documentation

◆ fold()

virtual LogicalResult mlir::DialectFoldInterface::fold	(	Operation *	op,
		ArrayRef< Attribute >	operands,
		SmallVectorImpl< OpFoldResult > &	results
	)		const

inlinevirtual

Registered fallback fold for the dialect.

Like the fold hook of each operation, it attempts to fold the operation with the specified constant operand values - the elements in "operands" will correspond directly to the operands of the operation, but may be null if non-constant. If folding is successful, this fills in the results vector. If not, this returns failure and results is unspecified.

Definition at line 34 of file FoldInterfaces.h.

◆ shouldMaterializeInto()

virtual bool mlir::DialectFoldInterface::shouldMaterializeInto ( Region * region ) const

inlinevirtual

Registered hook to check if the given region, which is attached to an operation that is not isolated from above, should be used when materializing constants.

The folder will generally materialize constants into the top-level isolated region, this allows for materializing into a lower level ancestor region if it is more profitable/correct.
