Another testcase which effects all targets:
int logic_func1(int b, int d) {
if (d< b) return b+3; else return d+3;
}
int logic_func2(int b, int d)
{
int a;
if (d< b) a = b; else a = d;
return a+3;
}
Basicially if we move the +3 to the common code, this would be better (note in the orginal testcase it is
a cast).
