Some intrinsics/stubs missing vzeroupper on x86_64

XMLWordPrintable

    • b25
    • x86

        The following intrinsics/stubs are missing vzeroupper:
        adler32 (since JDK17)
        count_positives (since JDK 9)
        chacha20 (since JDK 20)
        string indexOfChar (since JDK 9)

        This could result in AVX-SSE transition penalties.
