[jira] [Commented] (HIVE-10189) Create a micro benchmark tool for
vectorization to evaluate the performance gain after SIMD optimization

What tools are you using to validate the generated assembly?
I used TriView which worked but was somewhat laborious.
Do you happen to have any pointers on how to write Java which exploits the full capability of SIMD? as in SSE Vs. AVX2 etc..
