[jira] Created: (HARMONY-3076) [drlvm][jit] Loop unrolling
optimization implementation in Jitirno.OPT
[drlvm][jit] Loop unrolling optimization implementation in Jitirno.OPT
----------------------------------------------------------------------
Key: HARMONY-3076
URL: https://issues.apache.org/jira/browse/HARMONY-3076
Project: Harmony
Issue Type: New Feature
Components: DRLVM
Reporter: Mikhail Fursov
Attachments: unroll_1.zip
Here is an implementation of loop unrolling optimization.
The patch enables it in all modes with Jitrino.OPT we have.
There are some TODOs, described in loop_unroll.cpp files, read it if you are interested to write minitests to see performance improvements.
My minitests shows that we have ~50% improvement on classic BubbleSort application and ~15% for Arrays.sort when dynamic edge profile is used.
