"Tautological pointer comparison" build failure(s)
clang 12.0.1
Incorrect code...
#include
void foo() {
int arr[5];
int x;
// warn on these conditionals
if (foo);
if (arr);
if (&x);
if (foo == NULL);
if (arr == NULL);
if (&x == NULL);
}
void f(int &x) {
if (&x == nullptr) { }
}
gcc with -Wall also detects some of these errors but not the one involving NULL.
