--- Comment #2 from Drea Pinski <pinskia at gcc dot gnu.org> ---
We handle MIN/MAX_EXPR here:
```
(for minmax (min max)
maxmin (max min)
(simplify
(minmax @0 @0)
@0)
/* max(max(x,y),x) -> max(x,y) */
(simplify
(minmax:c (minmax:c@2 @0 @1) @0)
@2)
```
Should be simple to add a similar for FMIN_ALL/FMAX_ALL here like what is done
for min/max(a,a):
```
(for minmax (FMIN_ALL FMAX_ALL)
(simplify
(minmax @0 @0)
(if (!tree_expr_maybe_signaling_nan_p (@0))
@0)))
```
