test.c
```
#include <stdio.h>
#pragma GCC visibility push(hidden)
void __attribute__((__weak__)) xxx(void)
{
printf("weak\n");
}
void call_func(void (*f)(void));
int main()
{
call_func(xxx);
return 0;
}
```
test1.c
```
#include <stdio.h>
#pragma GCC visibility push(hidden)
void xxx(void)
{
printf("default\n");
}
void call_func(void (*f)(void))
{
f();
}
```
opts:
arm32-clang test.c test1.c -static -fpic
result:
```
weak
```
arm32-gcc test.c test1.c -static -fpic
result:
```
default
```

I believe this issue is closely related to how weak symbol function pointers are loaded. How can we fix this problem to align with GCC's behavior?
