java - 解决 armv8 中的数独问题，该数独打印数字直到 13 而不是 9

Question

下面是我试图转换成 armv8 的 java 代码。他的 armv8 代码是我的工作。它似乎不能正常工作，因为它目前使用 1 到 13 的数字，而数独应该只使用数字 1-9。

我有一个静态表，它用 1 到 9 的随机数和一些零初始化。当程序正在玩游戏时，应该替换这些零。

private boolean isAllowed(int row, int col,int number)
{
    return !(containsInRow(row, number) || containsInCol(col, number) || containsInBox(row, col, number));
}

public boolean solveSudoku()
{
    for(int row=0;row<9;row++)
    {
        for(int col=0;col<9;col++)
        {
            if(sudoku[row][col]==UNASSIGNED)
            {
                for(int number=1;number<=9;number++)
                {
                    if(isAllowed(row, col, number))
                    {
                        sudoku[row][col] = number;
                        if(solveSudoku())
                        {
                            return true;
                        }
                        else
                        {
                            sudoku[row][col] = UNASSIGNED;
                        }
                    }
                }
                return false;
            }
        }
    }
    return true;
}

我创建的汇编代码版本：

solveSudoku:

    add x29,sp,0

         mov     w19,0      //w19=Register for rows
        mov     w20,0       //w20=Register for col
    mov     w24,1       //w24=register for numbers

solve:
        adrp    x0,tab
        add     x0,x0,:lo12:tab

        mov     w27,9       

         and     w22,w22,wzr    //set 0 to w22
        mul     w22,w27,w19 
        add     w22,w22,w20 
        lsl     w22,w22,2   //calculate the table position

        ldr     w23,[x0,x22]    //w23=number in specific position in the table(position calculate above in w22)
        cbnz    w23,.incCol //if is not zero go to label .incCol to increase the j

//        mov     w24,1

        mov     w2,w19

        str wzr,[x0,x25]    //if is zero store zero to the position had changed above
    b   .next       
.next:

        cmp     w24,10      //if number is 10 set register w21 to 0 and return
        b.eq    .again
        b       nums        //go back to check next number

        b.eq    .incLine
        b.ne    solve       //if is not 9 go back to check next column

.incLine:
        sub     w20,w20,9   //set col back to 0
        add     w19,w19,1   //increase row
        cmp     w19,9       //if row is 9 set register w21 to 1 and return
        b.eq   .end
        b.ne    solve       //if is not 9 go back to check next row

.again:

    ldp x29,x30,[sp],32
    ret
