* clang-format * remove unnecessary headers * Remove few remaining qualifiers _CCCL_NODISCARD This fixes the build, after the macro definition was removed in #4265 * fix headers * Cleanup libcu++ `force_include.h` test file (#4262) * there are no more tests in this header * Simplify and reduce data copying in algorithm.cuh * Much less tupling and untupling * A few additional simplifications and a few eliminations of copies * Fix ratio plot (#4099) * Fix ratio plot * [pre-commit.ci] auto code formatting --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Bernhard Manfred Gruber <bernhardmgruber@gmail.com> * Drop `_CCCL_NORETURN` (#4268) Co-authored-by: Michael Schellenberger Costa <miscco@nvidia.com> * fix clang portability issue in `__rcvr_with_env_t` and remove dead code (#4277) * change version check in `type_list.h` so that *NO* clang-19.X compilers try to use pack indexing (#4278) * fix shfl check (#4282) * Add necessary headers * tweak the cccl compiler version check macros to better agree with intuition (#4279) * tweak the cccl compiler version check macros to better agree with intuition prior to this commit, a compiler check such as: ```c++ ``` would fail if the compiler was actually v19.1. that is because 19.1 is greater than 19. what the author of this code probably intended was to check only the compiler's major version number, in which case the check would have succeed. this commit changes the behavior of the following macros when only a major version number is specified: * `_CCCL_COMPILER` * `_CCCL_CUDA_COMPILER` * `_CCCL_CUDACC_BELOW` * `_CCCL_CUDACC_AT_LEAST` * guard `_CCCL_COMPILER(FOO)` with an extra set of parens * Implement `ranges::single_view` (#4255) * Implement fp overflow handlers (#4261) * Implement fp overflow handlers * I hate nvfp types * use `[[nodiscard]]` --------- Co-authored-by: Michael Schellenberger Costa <miscco@nvidia.com> * Fix CI failure * Drop `_LIBCUDACXX_HAS_NO_UNICODE_CHARS` (#4295) * [Version] Update main to v3.1.0 (#4175) * Bump main to 3.1.0. * Update ci/update_version.sh to edit the docs VERSION.md file * Rerun ci/version_update.sh --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Wesley Maxey <wesley.maxey@gmail.com> * WIP: Refactor allocators * Make metadata direct member instead of pointer * Add cached_block_allocator_fifo from PR #2674 * use _CCCL_ASSERT instead of assert * add missing ctors --------- Co-authored-by: Cedric Augonnet <caugonnet@nvidia.com> Co-authored-by: Oleksandr Pavlyk <21087696+oleksandr-pavlyk@users.noreply.github.com> Co-authored-by: David Bayer <48736217+davebayer@users.noreply.github.com> Co-authored-by: Georgii Evtushenko <evtushenko.georgy@gmail.com> Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Bernhard Manfred Gruber <bernhardmgruber@gmail.com> Co-authored-by: Michael Schellenberger Costa <miscco@nvidia.com> Co-authored-by: Eric Niebler <eniebler@nvidia.com> Co-authored-by: Federico Busato <50413820+fbusato@users.noreply.github.com> Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Wesley Maxey <wesley.maxey@gmail.com> Co-authored-by: Cédric Augonnet <158148890+caugonnet@users.noreply.github.com>
