Use XMM/YMM for objects initialization

XMLWordPrintable

    • b18
    • x86
    • generic

        Right now, for longer lengths we use "rep stos" instructions on x86, for short lengths we use "mov rax". Experiments show that we can use XMM/YMM registers for middle lengths to improve objects initialization perofrmance.
