Gate use of raw and function pointers in const generics behind const_compare_raw_pointers. 2019-10-04 21:49:24 +00:00
Remove the const_raw_ptr_comparison feature gate. We can never supply a meaningful implementation of this. Instead, the follow up commits will create two intrinsics that approximate comparisons: * `ptr_maybe_eq` * `ptr_maybe_ne` The fact that `ptr_maybe_eq(a, b)` is not necessarily the same value as `!ptr_maybe_ne(a, b)` is a symptom of this entire problem. 2020-06-12 17:25:14 +00:00			`struct Const<const P: *const u32>; //~ ERROR: using raw pointers as const generic parameters`
