在 c 中通过引用传递后，参数的位置发生了变化

Question

谁能解释一下为什么变量橙色的位置会改变以及如何防止？ 这是我将调试中显示的反汇编也作为注释留下的函数

int foo(int table)
{
    uint64_t orange = 0; // --> location of orange is 0x2000D7F8, it is R7
    // MOVS    R2, #0
    // MOVS    R3, #0
    // STRD    R2, R3, [R7]
   
    int ret = get_orange(table, &orange);
    // MOV     R3, R7
    // BL      get_orange       ; 0x0800BE20
    // MOV     R4, R0

    ...
}

//int bar(int t, uint64_t *orange)
int get_orange(int t, uint64_t *orange)  // --> location of *orange is 0x2000D7F8, now it is R3
{
    int location = room[0].table[t].location;
    // LDR:    R2, =room        ; [0x0800BF5C] = 0x240028D0
    // MOVS:   R3, #0xA8
    // MLA:    R3, R3, R0, R2   ; this changes the location of *orange, now location of *orange is 0x01 (?!) and location of orange is 0x2000D7F8
    // LDR.W   R6, [R3, #0xD80]
    
    ...

    printf("orange = %llu", *orange); // cannot print anymore since *orange is 0x01
    // LDR    R3, [R7, #4]
    // LDRD   R2, R3, [R3]
    // LDR    R0, =0x0808F294        ; [0x0800BF64]
    // BL     printf
}
