RE: https://chaos.social/@icing/117398069550473355 I’ve complained about this before, but this is not something you can usefully do from the front-end. If we really want things zeroed, we need compiler functionality that asks the back end to ensure that the data is gone as soon as possible after it’s no longer needed and no later than when the function returns, either by having the register or memory reused, or cleared if there’s no good reuse opportunity
