Azat Khuzhin 1107988a82 Improve performance of BLAKE3 by 11% by enabling LTO for Rust ... LTO in Rust produces multiple definition of `rust_eh_personality' (and few others), and to overcome this --allow-multiple-definition has been added. Query for benchmark: SELECT ignore(BLAKE3(materialize('Lorem ipsum dolor sit amet, consectetur adipiscing elit'))) FROM numbers(1000000000) FORMAT `Null` upstream : Elapsed: 2.494 sec. Processed 31.13 million rows, 249.08 MB (12.48 million rows/s., 99.86 MB/s.) upstream + rust lto: Elapsed: 13.56 sec. Processed 191.9 million rows, 1.5400 GB (14.15 million rows/s., 113.22 MB/s.) llvm BLAKE3 : Elapsed: 3.053 sec. Processed 43.24 million rows, 345.88 MB (14.16 million rows/s., 113.28 MB/s.) Note, I thought about simply replacing it with BLAKE3 from LLVM, but: - this will not solve LTO issues for Rust (and in future more libraries could be added) - it makes integrating_rust_libraries.md useless (and there is even blog post) So instead I've decided to add this quirk (--allow-multiple-definition) to fix builds.
