Bug ID: 65659
Summary: STL containers not specialized for pointer value_type
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: marc at kdab dot com
The STL containers are not specialised for pointer types, leading to tons of
duplicated virtually-identical binary code.
Example:
vector<const T*> could be implemented in terms of vector<T*>
vector<T*> could be implemented in terms of vector<void*>
vector<shared_ptr<const T>> could be implemented in terms of
vector<shared_ptr<T>>
vector<chared_ptr<T>> could be implemented in terms of
vector<shared_ptr<void>>
Is there anything that prevents this rather obvious optimisation? Allcators
having the wrong type?
