RISC-V: improve performance of copy_memory stub

XMLWordPrintable

    • b25
    • riscv
    • linux

        Currently copy_memory stub on risc-v is doing 8-byte copy per loop at best

        We can improve that to 32-bytes per loop ( doing it similar to memcpy in newlib) - four ld and four sd per loop
        Also copy_memory produces some dead ( never executed) code when is_aligned is true. Lets eliminate that as well
