Synopsis

Declared in <llvm/Transforms/IPO/Attributor.h>

struct AAMemoryBehavior
    : IRAttribute<Attribute::None, StateWrapper<BitIntegerState<uint8_t, 3>, AbstractAttribute>, AAMemoryBehavior>

Name	Description
`IRAttribute<Attribute::None, StateWrapper<BitIntegerState<uint8_t, 3>, AbstractAttribute>, AAMemoryBehavior>`	Helper class that provides common functionality to manifest IR attributes.

Name	Description
`Unnamed enum`	State encoding bits. A set bit in the state means the property holds. BEST_STATE is the best possible state, 0 the worst possible state.

Name	Description
`AAMemoryBehavior` [constructor]	Create a AAMemoryBehavior for the position `IRP.`
`getAttrKind`	Return the kind that identifies the abstract attribute implementation.
`getDeducedAttributes` [virtual]	Return the deduced attributes in `Attrs.`
`getIdAddr` [virtual]	See AbstractAttribute::getIdAddr()
`getName` [virtual]	See AbstractAttribute::getName()
`isAssumedReadNone`	Return true if we assume that the underlying value is not read or accessed in its respective scope.
`isAssumedReadOnly`	Return true if we assume that the underlying value is not accessed (=written) in its respective scope.
`isAssumedWriteOnly`	Return true if we assume that the underlying value is not read in its respective scope.
`isKnownReadNone`	Return true if we know that the underlying value is not read or accessed in its respective scope.
`isKnownReadOnly`	Return true if we know that the underlying value is not accessed (=written) in its respective scope.
`isKnownWriteOnly`	Return true if we know that the underlying value is not read in its respective scope.
`manifest` [virtual]	See AbstractAttribute::manifest(...).

Name	Description
`classof`	This function should return true if the type of the `AA` is AAMemoryBehavior
`createForPosition`	Create an abstract attribute view for the position `IRP.`
`hasTrivialInitializer`	See AbstractAttribute::hasTrivialInitializer.
`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.
