<pre>When a jump table label points to a jump its address could be just placed into
the jump table. An example:
int f1();
int f2();
int f3();
int f4();
int f5();
int foo(int i)
{
switch (i) {
case 1: return f1();
case 2: return f2();
case 3: return f3();
case 4: return f4();
case 5: return f5();
}
}
GCC does not do this optimization too, but there is an old ticket on this with
an additional info <a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=14721">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=14721</a></pre>
