| Summary | 0001190: __builtin_alloca | ||||
| Description | In a file with a local array which size in defined by a variable : float a[n]; I get : [kernel] warning: Variable-sized local variable a which is ok. But then, when I use the value analysis, I get : [kernel] warning: No code for function __builtin_alloca, default assigns generated because the declaration has been translated in : __lengthofa = (unsigned int)n; a = (float *)__builtin_alloca(sizeof(*a) * __lengthofa); which looks fine, but the question is : shouldn't the assigns property be defined somewhere inside Frama-C for the builtin functions ? As a workaround, what prototype and assigns should I write for this function. | ||||
