--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
For C++ (well with GCC extensions obvious) this would be valid:
```
static constexpr const char *names[] = {
[CE_RED] = "RED",
[CE_GREEN] = "GREEN",
[CE_BLUE] = "BLUE",
};
```
And gets optimized way.
But for C23, constexpr pointers have to be null.
In the original testcase you refer to `&name[0][0]` as you pass to puts. Since
you take the address of name, it still needs to be a variable.
