Example 4:
int a;
int b[10];
f() {
}
In this example, a in expression (3) is referenced once before the loop and is always handled as
a constant value in the loop as a result of optimization.
Example 5:
int a;
f() {
}
In this example, the statement (1) is assumed as unnecessary and eliminated as a result of
optimization.
Obtains the control flow including the for loop control expression.
Due to analyzing the control flow analysis and alias analysis of external variables, a in (3)
is handled as a constant value in the loop.
(3) which is the reference expression to a is moved outside the for loop (2) as follows:
Therefore, the variable a in expression (3) is unchanged in the loop.
Since (2) is an infinite loop, this function is judged to have no exit.
Since a is not referenced in the infinite loop, specification (1) is assumed as unnecessary
coding and is eliminated.
