Per Andrew's request:
For GCC built for RISC-V,
With the following code:
struct sss_t {
int i;
int j;
} sss;
extern char array[sizeof(struct sss_t )];
void foo()
{
struct sss_t *p = (struct sss_t *)ar

With 'extern', four 'sb' are ued to store value into "p->i";
while without 'extern', only one 'sw' is used.
