Hi Michihiro,

I wonder if there is no vectorized approach for implementing your "bytes_reverse_long_Ex" instruct on ppc.ad. Or did you avoid doing it so intentionally?

Dear all, Would you please review following change? Bug: https://bugs.openjdk.java.net/browse/JDK-8179527 Webrev: http://cr.openjdk.java.net/~horii/8179527/webrev.00/ I added new intrinsic code for reverseBytes() in ppc.ad with * match(Set dst (ReverseBytesI/L/US/S (LoadI src))); * match(Set dst (StoreI dst (ReverseBytesI/L/US/S src)));

Best regards, -- Michihiro, IBM Research - Tokyo
