Subject: [Bug c++/112335] missed optimization on reset and assign unique_ptr
Date: Thu, 02 Nov 2023 07:17:53 +0000 [thread overview]
Message-ID: <bug-112335-4-jvtBHVKYUN@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #2 from Federico Kircheis <federico at kircheis dot it> ---
> Well s::~s could touch the reference std::unique_ptr<s> (ps1).
In both cases, s::~s is called only once.
Also during the move-assignment no user-provided-code is involved (except the
destruction of ps1, and even case of a user-provided deleter, it is only called
if the pointer is not nullptr.
