By the way, I find same problem in legalize-uadde-rv32.mir,legalize-uadde-rv64.mir, is it need to modify it?

    %0:_(s64) = COPY $x10
    %1:_(s64) = COPY $x11
    %2:_(s64) = COPY $x12
    %3:_(s64) = COPY $x13
    %4:_(s64) = COPY $x14
    %5:_(s1)  = G_TRUNC %4(s64)
    %6:_(s64), %7:_(s1) = G_UADDE %0, %2, %5
    %8:_(s64), %9:_(s1) = G_UADDE %1, %3, %7
    %10:_(s64) = G_ANYEXT %9(s1)
    $x10 = COPY %6(s64)
    $x11 = COPY %8(s64)
    $x12 = COPY %10(s64)
