Hyperscan: A Fast Multi-Pattern Regex Matcher for Modern CPUs

I ported Hyperscan to ARM several months ago with help from the following project: https://github.com/nemequ/simde

Would you be interested in working together to get an ARM port that's a bit cleaner and author-approved?

I understand this possibility, but it's not the way I would do an ARM port in an ideal world.

Being the original designer of Hyperscan isn't much help; I don't work at Intel any more and wouldn't have all that much clout in trying to get an ARM port into the codebase.

I'm thinking about building a followup regex matcher - considerably smaller scale, and starting with a Hyperscan code base for the tools/infrastructure/boring bits - ("ure3"). This would definitely have ARM as a first-class architecture. Anyone 64-bit and little-endian can play, I would think (legacy stuff like 32-bit, etc can go somewhere else).

I just with the ARM guys would get their shit together and support their own much ballyhooed SVE. The idea of announcing something in 2016 and not supporting it in a server chip that's due for mid-2020 is... novel.

Does the ARM version hyperscan work well? Can you describe the detailed steps? Thanks
