Arm64 specific support for lj_new_str random hash optimization

Open debayang opened this issue 7 years ago • 2 comments

This ports the random hash optimization done for lj_new_str() for x64 ( in https://github.com/openresty/luajit2/commit/7923c63 ) to arm64.

Verified on Arm64 platform with the existing benchmark developed as part of the x64 commit above - shows similar improvements as seen for x64 with this benchmark.

However not sure about the effect on any real time workloads.
