--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
As mentioned in comment #0, this is a generic C/C++ improvement: "The test case
is C++ but a similar improvement applies to the C front end." In fact, it's
even more relevant to C where the warning doesn't underline the argument it
refers to:
Here's a corresponding C test case. Wh
$ cat pr95625.c && gcc -O2 -S -Wall -Wextra pr95625.c
void f (int, int, int, _Bool, int *);
void g (int i)
{
f (1, 2, 3, &i, &i);
}
pr95625.c: In function ‘g’:
pr95625.c:5:3: warning: the address of ‘i’ will always evaluate as ‘true’
[-Waddress]
5 | f (1, 2, 3, &i, &i);
