    demo:

```
__attribute__((section(".custom"))) static const int data = 123;

const int* get_data()
{
  return &data;
}

int main()
{
  (void)get_data();
} 
```

`clang demo.c -c -o demo.o `
clang version 15.0.4
```
readelf -SW demo.o
There are 11 section headers, starting at offset 0x300:

But if I delete function get_data, custom  section wouldn't  be generated, this is a bug?
