Hi Michihiro, this looks good to me. We should be able to test it since it is for Power8. Maybe Gustavo would like to test in addition.

This change supports FMA vectorization on PPC64. Bug: https://bugs.openjdk.java.net/browse/JDK-8215262 Webrev: http://cr.openjdk.java.net/~mhorie/8215262/webrev.00/ Microbenchmark I used is http://cr.openjdk.java.net/~mhorie/8215262/VFma.java It showed ~50% reduction in the execution time. I also tested with JTREG and there was no difference in the results compared to the original. Best regards, -- Michihiro, IBM Research - Tokyo
