Optimize SIMD sort for AMD Zen 4

XMLWordPrintable

    • x86
    • linux

      In JDK-8309130 Array sort was optimized using SIMD instructions for x86_64.
      This optimization needed to be disabled for AMD Zen 4 in JDK-8317763 due to bad performance of compressstoreu as per https://www.reddit.com/r/java/comments/171t5sj/heads_up_openjdk_implementation_of_avx512_based/.
