| Summary | 0001353: ACSL label LoopEntry not handled by WP |
| 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++;
}
