Description
Hello,
The std::is_trivial type trait has been deprecated in C++26 by https://isocpp.org/files/papers/P3247R2.html ; some code in oneDPL is still using it, and needs to be ported away.
https://github.com/search?q=repo%3Auxlfoundation%2FoneDPL%20std::is_trivial&type=code
Note that I'm talking specifically about is_trivial and is_trivial_v, the other type traits are OK.
The direct (= semantically equivalent) non-deprecated replacement of is_trivial_v<T> would be to check for std::is_trivially_default_constructible_v<T> && std::is_trivially_copyable_v<T>.
However the ideal replacement is to reason about what exact type properties are needed, and test for those using specific type traits; for instance, check for trivial copy assignment, trivial destruction, and so on.
(The problem is that the definitions of trivial/trivially copyable encompass too much, and are inaccurate.)
Please also see the remarks to this mailing list thread for libstdc++: https://gcc.gnu.org/pipermail/libstdc++/2024-December/060119.html
Thanks,
