Variable is not defined

[SergeyKopienko]

Variable policy1 is not defined at

oneDPL/include/oneapi/dpl/internal/exclusive_scan_by_segment_impl.h

Line 86 in 1029fe9

replace_copy_if(policy1, first2, last2 - 1, _flags.get() + 1, _temp.get() + 1, ::std::negate<FlagType>(), init);

in the next code:

    // TODO : add stencil form of replace_copy_if to oneDPL if the
    // transform call here is difficult to understand and maintain.
#if 1
    // ...
#else
    replace_copy_if(policy1, first2, last2 - 1, _flags.get() + 1, _temp.get() + 1, ::std::negate<FlagType>(), init);
#endif

But its use simple hidden under macro definition checks so we haven't any compile-time errors.

This code will also never compile with oneDPL if policy1 did exist since it is using a form of replace_copy_if that is an extension to the C++ spec that we only provide in compatibility headers.

In my opinion, we can just remove it as it's been here since 2020, and I don't think there are any plans to provide such APIs directly into oneDPL.
