Neon-Optimized hash chain This should help with compression of data, using NEON instructions (therefore useful for ARMv7/ARMv8). Average gains were around 4% to 5% in data compression, depending on the data entropy. Re-write of a patch contributed to Fedora Core, for reference: https://src.fedoraproject.org/rpms/zlib/c/25e9802713484882c27c1f979a6610a42414ee13?branch=master Bug: 863257 Change-Id: I76573d75843d6a63de75d8a9536da98515314543 Reviewed-on: https://chromium-review.googlesource.com/1136940 Reviewed-by: Mike Klein <[email protected]> Reviewed-by: Chris Blume <[email protected]> Commit-Queue: Adenilson Cavalcanti <[email protected]> Cr-Commit-Position: refs/heads/master@{#581241}
