Clang with gnu libstdc++ produces code very slow in generating random real numbers on Arm64. This patch implements three random utilities based on clang libc++: - std::generate_canonical - std::random_real_distribution - std::bernoulli_distribution It brings ~100x speedup on Arm64 and ~8x on x86_64 in generating random reals when build arrow with clang + gnu libstdc++. No influence to gcc + libstdc++, or clang + libc++. -- This is an automated message from the Apache Git Service.
