Member Function Documentation
◆ copy()
|
pure virtual |
Copy constructor.
Makes a new copy of this pool.
Implemented in Rose::BinaryAnalysis::CallingConvention::StoragePoolEnumerated, and Rose::BinaryAnalysis::CallingConvention::StoragePoolStack.
◆ canStore()
|
virtual |
Test whether locations can store type.
If this pool contains locations that are capable of storing an instance of the specified type, then this predicate returns true, else false.
◆ reset()
|
pure virtual |
Reset allocation.
Resets this storage pool back to its initial state. For instance, if the storage pool contains a list of three explicit locations and some or all of them have been taken by consume, then calling this function will make all three available again.
Implemented in Rose::BinaryAnalysis::CallingConvention::StoragePoolEnumerated, and Rose::BinaryAnalysis::CallingConvention::StoragePoolStack.
◆ consume()
|
pure virtual |
Consume a storage location.
Given an argument type, return a location(s) if possible and remove that location from this pool.
Implemented in Rose::BinaryAnalysis::CallingConvention::StoragePoolEnumerated, and Rose::BinaryAnalysis::CallingConvention::StoragePoolStack.
◆ constantLocations()
|
virtual |
List of constant storage locations.
A constant location is any location whose address is known and is a constant. For example, a ConcreteLocation describing a particular register or memory location is a constant location, but a ConcreteLocation that describes a memory address which is stored in a register or a memory address that is the sum of a register value and an offset is not constant.
The constant values are used by the calling convention Analysis to check whether the callee reads from any of these locations without first writing to them.
The base implementation returns an empty vector.
Reimplemented in Rose::BinaryAnalysis::CallingConvention::StoragePoolEnumerated.
