Description :

As said in the title, the ACSL label LoopEntry seems to be not handled by WP but it is accepted by the kernel. Using the -wp-warnings option I got warnings like :

• Warning: Generalization of un-labeled values Reason: Some labels may escape the control flow but it took me some time to understand the problem.

In the example below, changing LoopEntry by L in the loop invariant makes it work.

BTW, in the example below, it doesn't work either when removing the first (c++;) statement !

Additional Information :

int G; //@ requires G == 0; ensures G == 0; void f (int c) { c++; L: //@ loop invariant G == \at (G, LoopEntry); while (c) c++; }
