### Description Fix an issue in `concurrent_set` and `concurrent_unordered_set` - `iterator` types should be constant for these classes. Current implementation allows to write the following: ``` oneapi::tbb::concurrent_set s = {1,...

Fix common config for including STL headers before oneDPL on GCC9 and GCC10

There is an issue while STL headers before `` on GCC9 and GCC10 with modern oneTBB versions: ``` #include #include int main() { ... } ``` Any STL header includes...

Fix serial execution of parallel algorithms with C++20 iterators

2

I propose this PR as a fix for #1253. Our internal random access iterator checks relied on `std::iterator_traits::iterator_category` type. But for C++20 iterators, like `std::ranges::iota_view::iterator`, `iterator_category` is equivalent to `std::input_iterator_tag`...

Add workaround to parallel merge in TBB backend not to use input iterators default constructor

6

Add workaround to implementation of __parallel_merge function for the following use case: ``` #include #include #include #include int main() { std::vector input1 = {1, 2, 3}; std::vector input2 = {1,...
