<pre>Consider the following:
int valeur;
volatile int bidule;
void toto() {
if (bidule) {
valeur = 65;
} else {
valeur = 33;
}
if (bidule) {
valeur++;
} else {
valeur--;
}
}
This code could be compiled with a single STORE instruction at the end, yet
gets compiled with two STOREs, the first of which is dead.</pre>
