[Frama-c-discuss] Frama-c: WP issues



I'm sorry. I overlooked something else.

Adding this code snippet to the end still claims "[wp] [Alt-Ergo] Goal typed_foo_assert : Unknown (Qed:8ms)"

 if (fRrValue == 0)
        {
            /*@ assert(tenumRMode == SS_A_MODE); */
        }

Hi,

One update:


I added this code snippet to the end of the foo function as given below.

 if (fRrValue == 0)
        {
           /*@ assert(tenumRMode == SS_A_MODE); */
        }


I removed the behavior basic from annotations. wp shows this assert is valid as expected.

It appears there is some problem in the way the basic behavior is parsed, transformed, etc.

Any comments?
Dharma

Hello,

You should always use the latest version (currently Fluorine).

Have you applied my suggestion (adding asserts)? We cannot help you much
without the code.

BTW, frama-c provides a C code obfuscator, it might be sufficient for
you to provide the code.

Best regards,
david
