Stabilize `const_raw_ptr_deref` for `const T` This stabilizes dereferencing immutable raw pointers in const contexts. It does not stabilize `mut T` dereferencing. This is placed behind the `const_raw_mut_ptr_deref` feature gate. 2021-10-05 08:55:57 +00:00			`// Check that you can't dereference invalid raw pointers in constants.`
Prevent comparison and dereferencing of raw pointers in constexprs Fixes #25826. 2015-05-27 21:35:56 +00:00
