Bug ID: 87029
Summary: Add -Wredundant-move
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mpolacek at gcc dot gnu.org
Target Milestone: ---
Similarly to 86981, we could also warn here about the redundant (but not
pessimizing) move here:
#include <utility>
struct S { };
S
foo (S s)
{
return std::move (s);
}
the compiler will try a move operation regardless the std::move (if the move
ctor is present and accessible).
Unless the parameter is const, of course.
