Detailed Description

This class provides a shared interface for box and class types.

Member Function Documentation

getBaseAddressType()

mlir::Type BaseBoxType::getBaseAddressType

(

bool

dropHeapOrPtr = false

)

const

Get the raw address type of the memory described by the box. When dropHeapOrPtr is true, the returned type is always a fir::ReferenceType.

getBoxTypeWithNewElementType()

fir::BaseBoxType fir::BaseBoxType::getBoxTypeWithNewElementType	(	mlir::Type	elementType,
		bool	polymorphic ) const

Return a box type with the same attributes and shape, except that the element type that is changed to the provided one. The returned box will be a fir.class if polymorphic is true and a fir.box otherwise.

getBoxTypeWithNewShape()

fir::BaseBoxType fir::BaseBoxType::getBoxTypeWithNewShape

(

mlir::Type

shapeMold

)

const

Return the same type, except for the shape, that is taken the shape of shapeMold.
