imraniac opened a new pull request, #48611: URL: https://github.com/apache/arrow/pull/48611
### Rationale for this change This change replaces custom implementations of bit manipulation functions with C++20 standard library functions from the <bit> header. This will reduce the code complexity. ### What changes are included in this PR? Updated the `cpp/src/arrow/util/bit_util.h` file to replace the custom implementation for `PopCount`, `CountLeadingZeros`, and `CountTrailingZeros` with C++20 standard library functions `std::popcount()`, `std::countl_zero()` and `std::countr_zero()` respectively. ### Are these changes tested? Yes ### Are there any user-facing changes? No, this is an internal refactoring of bit utility functions. -- This is an automated message from the Apache Git Service.
