Even simpler:
int f (int*);
int g(void);
int foo (void)
{
int b;
if (g() && f ())
return 0;
return b;
}
we have:
# .MEM_7 = VDEF <.MEM_6(D)>

Also to add, this could be suppressed if

struct{
Nr

I think the second is correct but I dont know the exact rules about enum
classes; are they unsigned by default? I know normal emuns are signed by
