Yeah my concern is that the contract of the function is kinda weird.
with error_at not a no return, the function would ICE on wi::to_widest
with a non INTEGER_CST argument. So ideally that should also be fixed,
and the you wouldn't have a minval.
But I any value returned by the function is only valid after seen_error ()
is called and returns false.
In this case you can move the asserts down slightly until after all three
require_const_argument and just do another
if (seen_error ())
return;
which should work no? and then you can also fix the
if (TREE_CODE (arg) != INTEGER_CST)
check in require_const_argument.
