struct AADereferenceable
    : IRAttribute<Attribute::Dereferenceable, StateWrapper<DerefState, AbstractAttribute>, AADereferenceable>

Name	Description
`IRAttribute<Attribute::Dereferenceable, StateWrapper<DerefState, AbstractAttribute>, AADereferenceable>`	Helper class that provides common functionality to manifest IR attributes.

Name	Description
`AADereferenceable` [constructor]	Create a AADereferenceable for the position `IRP.`
`getAssumedDereferenceableBytes`	Return assumed dereferenceable bytes.
`getAttrKind`	Return the kind that identifies the abstract attribute implementation.
`getDeducedAttributes` [virtual]	Return the deduced attributes in `Attrs.`
`getIdAddr` [virtual]	See AbstractAttribute::getIdAddr()
`getKnownDereferenceableBytes`	Return known dereferenceable bytes.
`getName` [virtual]	See AbstractAttribute::getName()
`isAssumedGlobal`	Return true if we assume that underlying value is dereferenceable(_or_null) globally.
`isKnownGlobal`	Return true if we know that underlying value is dereferenceable(_or_null) globally.
`manifest` [virtual]	See AbstractAttribute::manifest(...).

Name	Description
`classof`	This function should return true if the type of the `AA` is AADereferenceable
`createForPosition`	Create an abstract attribute view for the position `IRP.`
`hasTrivialInitializer`	Most boolean IRAttribute AAs don't do anything non-trivial in their initializers while non-boolean ones often do. Subclasses can change this.
`isImpliedByIR`	Return true if the IR already implies this attribute.
`isImpliedByPoison`	Return true if the IR attribute(s) associated with this AA are implied for an poison value.
`isImpliedByUndef`	Return true if the IR attribute(s) associated with this AA are implied for an undef value.
`isValidIRPositionForInit`	See AbstractAttribute::isValidIRPositionForInit

Name	Description
`ID`	Unique ID (due to the unique address)
`IRAttributeKind`	Compile time access to the IR attribute kind.
