| Summary | 0002021: Incorrect grammar for loop-behavior in document |
| Description | Grammar for loop-behavior in Fig2.9 in acsl.pdf (http://frama-c.com/download/acsl.pdf), page 36, has bug. loop-behavior has following grammar:
loop-behavior := for id (, id)* : loop-clause*
which means that having atleast one loop clause is not necessary. But if I don't add any loop-clause frama-c throws warning: unexpected token ' ' in line XX |
| Steps To Reproduce | Following example is correct as per the grammar of loop-behavior. But frama-c throws warning.
/*@ requires n>=0;
behavior fail :
ensures \result == -1;
*/
int example(double t[], int n, double v ){
int l=0, u= n-1;
/*@ loop invariant 0 <=l && u <= n-1;
for fail:
*/
while(l <= u){
l++;
}
return -1;
}
Note: this is contrived example |
