Hi Nathan, > this is untrue. the elements hold the qualification.
Then how do I know that an array is declared with const (or static const)? When I looked at the CONSTRUCTOR stored in the DECL_INITIAL of an array, I saw it with the TREE_STATIC flag set regardless of whether the array is declared with const, so that's not useful to determine whether the array is declared with const. All I need is a sufficient condition that works with C, C++, and any other language that GCC supports to determine whether it's safe to fold array[CST] into a constant. > Incorrect.

I see that in build_zero_init, so I tried a big array with only zeros in it, but that didn't help. Kazu Hirata
