--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced testcase:
```
struct rtx_def {
short mode;
short code;
int t[1024];
};
void f(rtx_def *a, short m, short c)
{
__builtin_memset(a, 0, sizeof (struct rtx_def));
a->mode = m;
a->code = c;
}
```
Oh we don't handle non DECL memset triming.
Wait we don't handle the following trimming either:
```
struct rtx_def {
int mode;
int code;
int t[1024];
};
void g(rtx_def*);
void f(int m, int c)
{
rtx_def a;
__builtin_memset(&a, 0, sizeof (struct rtx_def));
a.mode = m;
g(&a);
}
```
