| Summary | 0001079: Imprecision of 'Defs' when querying precise location |
| Description | -------------------------
typedef struct {
int a;
int b;
} ts;
ts t[10];
void init() {
t[1].a = 1;
t[1].b = 2;
}
unsigned int main () {
init();
return t[1].a;
}
------------------------
Requiring the instructions that define t[1].a in main yields both lines of function init, which is a bit imprecise. Since slicing main on its return value removes the line 't[1].b = 2', the pdg is probably precise enough. Thus the imprecision lies somewhere in Scope. |
