Bug ID: 19458
Summary: warn on pessimizing call to std::move
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected],
[email protected]
Classification: Unclassified
For instance:
T f() {
T v = { ... };
// ...
return std::move(v);
}
The move would be elided without the call to `std::move`.
We should warn in any case where an explicit call to `std::move` disables move
elision.
