bors 635c4a5e61 Auto merge of #114494 - est31:extend_useless_ptr_null_checks, r=jackh726 ... Make useless_ptr_null_checks smarter about some std functions This teaches the `useless_ptr_null_checks` lint that some std functions can't ever return null pointers, because they need to point to valid data, get references as input, etc. This is achieved by introducing an `#[rustc_never_returns_null_ptr]` attribute and adding it to these std functions (gated behind bootstrap `cfg_attr`). Later on, the attribute could maybe be used to tell LLVM that the returned pointer is never null. I don't expect much impact of that though, as the functions are pretty shallow and usually the input data is already never null. Follow-up of PR #113657 Fixes #114442		2023-09-16 03:40:20 +00:00
