Description :

It might be interesting that the Value analysis emit a message when it detect that the program point after a loop or a call is unreachable.

Just an idea...

Additional Information :

Example: void may_be_infinite (int c) { int x = 0; if (c > 0) { while (1) ; x = 1; // <-- unreachable } } void main (int cond) { int r = 0; if (cond > 0) { may_be_infinite (cond); r = 1; // <-- unreachable } else { may_be_infinite (cond); r = 2; } }
