It would give too many false positives. Also we do not warn for non-registers very consistently (due to the same reason). |
This code should warn that foo is used uninitialized, but it doesn't.. gcc 4.3 and gcc 4.4 both fail to report a warning extern void do_something(void **foo); extern int cond(void); int main(int argc, char *argv[]) { void *foo; if (cond()) do_something(&foo); *argv = foo; return 0; }
