<pre>
    Keeping the relocation type after relocation relax resulted in a mismatch between instructions and relocation items. Humbly ask why the linker does this. 
Use examples are as follows：

```
## a.s
.rodata
x:
.word 10
.text
.global _start
_start:
  adrp    x30, x
  add     x30, x30, :lo12:x
  adrp    x1, x
  add     x1, x1, :lo12:x
  adrp    x15, x
  add     x15, x15, :lo12:x
  adrp    x2, x
  add     x3, x2, :lo12:x
  adrp    x2, x
  add     x2, x3, :lo12:x
```
```
llvm-mc -filetype=obj -triple=aarch64 a.s -o a.o 
ld.lld a.o  -o a.exe -emit-relocs
objdump -dr a.o > a.dump
```

result is ：
```

```
It would be greatly appreciated if anyone could help answer this question.
