--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Clang gives even better diagnostic now:
<source>:7:17: error: cannot build range expression with array function
parameter 'arr' since parameter with array type 'int[10]' is treated as pointer
type 'int *'
for (auto i : arr)
^~~
<source>:4:11: note: declared here
int f(int arr[10])
^
GCC trunk gives:
<source>: In function 'int f(int*)':
<source>:7:17: error: 'begin' was not declared in this scope
7 | for (auto i : arr)
| ^~~
<source>:7:17: error: 'end' was not declared in this scope
