![In the following code, A and B are constants defined with #define:
typedef struct {
short x[A] [B]; /* Unknown constants A and B */
long y;
} str1;
typedef struct {
char array[B];
int t;
short s[A];
long u;
} str2;
void setVal (str1 *p, str2 *q) {
long v1 = q->t;
long v2 = q->u;
p->y = v1 + v2;
}
GCC generates the following code for the function setval:
setVal:
movslq 8(%rsi), %rax
addq 40(%rsi), %rax
movq %rax, 192 (%rdi)
