[Bug 1646927] [NEW] PPC64: Poor StrictMath performance due to non-optimized compilation

 

You have been subscribed to a public bug:

---Problem Description---
Currently fdlibm optimization is disabled for PPC64, as a consequence StrictMath methods like, but not limited to, sin(), cos(), and tan() perform poorly. 
 
---uname output---
Linux vm 4.4.0-47-generic #68-Ubuntu SMP Wed Oct 26 19:38:24 UTC 2016 ppc64le ppc64le ppc64le GNU/Linux
 
Machine Type = pKVM 
  
---Steps to Reproduce---
Please refer to:
https://bugs.openjdk.java.net/browse/JDK-8170153
 
Userspace package: openjdk-8-jre:ppc64el                 8u111-b14-2ubuntu2.16.04.2 

Dear maintainer, please consider applying the fix already present
upstream. Backport is trivial. Thank you.
