I _think_ you would need to update the preprocessor macros in this [file](https://github.com/apache/arrow/blob/main/cpp/src/arrow/util/bit_util.h) (maybe with #ifdef something?) to not return the builtin `__builtin_popcount` but rather the software solution... this is mostly speculation so it might be wrong too :D (also I think popcnt is performance critical for arrow so YMMV, but that's pure speculation again) -- This is an automated message from the Apache Git Service.
