2020-08-14Enable arm64 optimizations that exist for power/x86 (#3393)AGSaidi
* Enable unaligned accesses on arm64 64-bit Arm platforms support unaligned accesses. Running the string benchmarks this change improves performance by an average of 1.04x, min .96x, max 1.21x, median 1.01x * arm64 enable gc optimizations Similar to x86 and powerpc optimizations. | |compare-ruby|built-ruby| |:------|-----------:|---------:| |hash1 | 0.225| 0.237| | | -| 1.05x| |hash2 | 0.110| 0.110| | | 1.00x| -| * vm_exec.c: improve performance for arm64 | |compare-ruby|built-ruby| |:------------------------------|-----------:|---------:| |vm_array | 26.501M| 27.959M| | | -| 1.06x| |vm_attr_ivar | 21.606M| 31.429M| | | -| 1.45x| |vm_attr_ivar_set | 21.178M| 26.113M| | | -| 1.23x| |vm_backtrace | 6.621| 6.668| | | -| 1.01x| |vm_bigarray | 26.205M| 29.958M| | | -| 1.14x| |vm_bighash | 504.155k| 479.306k| | | 1.05x| -| |vm_block | 16.692M| 21.315M| | | -| 1.28x| |block_handler_type_iseq | 5.083| 7.004| | | -| 1.38x| Notes: Merged-By: nurse <naruse@airemix.jp>
2017-01-20switch SipHash from SipHash24 to SipHash13 variantshyouhei
SipHash13 is secure enough to be used in hash-tables, and SipHash's author confirms that. Rust already considered switch to SipHash13: https://github.com/rust-lang/rust/issues/29754#issue-116174313 Jean-Philippe Aumasson confirmation: https://github.com/rust-lang/rust/issues/29754#issuecomment-156073946 Merged pull request: https://github.com/rust-lang/rust/pull/33940 From: Sokolov Yura aka funny_falcon <funny.falcon@gmail.com> Date: Thu, 8 Dec 2016 20:31:29 +0300 Signed-off-by: Urabe, Shyouhei <shyouhei@ruby-lang.org> Fixes: [Feature #13017] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57382 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
