No progress in GCC 11 (my bad). I'll see if I can remember for GCC 12. Below
is a C test case (in C++ the warning is included in -Wall).
$ (set -x && cat pr90043.c && gcc -S -Wall -Wextra -Wpedantic pr90043.c && gcc
-S -Wall -Wextra -Wpedantic -Winit-self pr90043.c)
+ cat pr90043.c
int f (void)
{
int i = i;
return i;
}
+ gcc -S -Wall -Wextra -Wpedantic pr90043.c
+ gcc -S -Wall -Wextra -Wpedantic -Winit-self pr90043.c
pr90043.c: In function ‘f’:
pr90043.c:3:7: warning: ‘i’ is used uninitialized [-Wuninitialized]
3 | int i = i;
| ^
pr90043.c:3:7: note: ‘i’ was declared here
3 | int i = i;
| ^

I remember when I added -Winit-self, it was specifically because that was the
original documented way of disabling uninitialized variables. I don't remember
if I came up with the option name or it was changed. It was a long time back in
the 4.0 days even.
