Thanks for your indications !

  • Hello jensbauer,

    I think it might be impossible to make 64-bit compare routine witch Cortex-M.

    In Cortex-M4 case, it would take at least four instructions even if IT instruction was used.

    In Cortex-M0 case, more instructions would be needed, Please give me hint.

    Best regards,

    Yasuhiko Koumoto.
