Archana R 7ca1e2aa56 internal/bytealg: optimize index function for ppc64le/power9 ... Optimized index2to16 loop by unrolling the loop by 4. Multiple benchmark tests show performance improvement on POWER9. Similar improvements are seen on POWER10. Added tests to ensure changes work fine. name old time/op new time/op delta Index/10 18.3ns ± 0% 19.7ns ±25% ~ Index/32 75.3ns ± 0% 69.2ns ± 0% -8.22% Index/4K 5.53µs ± 0% 3.69µs ± 0% -33.20% Index/4M 5.64ms ± 0% 3.75ms ± 0% -33.55% Index/64M 92.9ms ± 0% 61.6ms ± 0% -33.69% IndexHard2 1.41ms ± 0% 0.93ms ± 0% -33.75% CountHard2 1.41ms ± 0% 0.93ms ± 0% -33.75% Change-Id: If9331df6a141a4716724b8cb648d2b91bdf17e5f Reviewed-on: https://go-review.googlesource.com/c/go/+/377016 Reviewed-by: Cherry Mui <cherryyz@google.com> Reviewed-by: David Chase <drchase@google.com> Reviewed-by: Paul Murphy <murp@ibm.com> TryBot-Result: Gopher Robot <gobot@golang.org> Run-TryBot: Archana Ravindar <aravind5@in.ibm.com>		2022-05-09 12:02:02 +00:00
