class CXX17ElidedCopyReturnedValueConstructionContext

Declaration

class CXX17ElidedCopyReturnedValueConstructionContext
    : public ReturnedValueConstructionContext { /* full declaration omitted */ };

Description

Represents a temporary object that is being immediately returned from a function by value, eg. return t; or return T(123); in C++17. In C++17 there is not going to be an elidable copy constructor at the return site. However, the usual temporary-related bureaucracy (CXXBindTemporaryExpr, MaterializeTemporaryExpr) is normally located in the caller function's AST. Note that if the object has trivial destructor, then this code is indistinguishable from a simple returned value constructor on the AST level; in this case we provide a simple returned value construction context.
