typedef struct {
double m_a;
double m_b;
double m_c;
double m_d;
} AtLeast32BytesObject;
static AtLeast32BytesObject __attribute__((noinline,noclone)) CalledFunction()
{
AtLeast32BytesObject result = {1.1, 2.2, 3.3, 4.4};
return result;
}
void __attribute__((noinline)) _start() {
volatile AtLeast32BytesObject result = CalledFunction();
while(1) {}
}
Will miscompile without needing LTO.
