Hi, when `[[gnu::nonstring]]` is applied to a variable of type `char *`, clang reports this as unsupported.
However, this functionality works on gcc and it is useful.
This is on clang 21.1.0-rc1.
`warning: 'gnu::nonstring' attribute only applies to fields or variables of character array type; type is 'char *' [-Wignored-attributes]`
This is the minimal example:
```
#include <string.h>
#include <stddef.h>
typedef struct
{
[[gnu::nonstring]] char *data; /* no clang support */
size_t size;
} Thing;
size_t foo(Thing *x)
{
return strlen(x->data); /* warns on gcc */
}
```
