Constify the following methods of `core::cmp::Ordering`: - `reverse` - `then` Possible because of rust-lang#49146 (Allow `if` and `match` in constants).
- most are using primitive types links, which cannot be used with intra links at the moment - also `std` cannot be referenced in any link
reference counted pointer -> reference-counted pointer
Co-authored-by: Joshua Nelson <joshua@yottadb.com>
`alloc::slice` uses `core::slice` functions, documentation are copied from there and the links as well without resolution. `crate::ptr...` cannot be resolved in `alloc::slice`, but `ptr` itself is imported in both `alloc::slice` and `core::slice`, so we used that instead.
Fixes rust-lang#75930 This changes the tokens seen by a proc-macro. However, ising a `#[cfg]` attribute on a generic paramter is unusual, and combining it with a proc-macro derive is probably even more unusual. I don't expect this to cause any breakage.
This commit removes the obsolete printer and replaces all uses of it with `FmtPrinter`. Of the replaced uses, all but one use was in `debug!` logging, two cases were notable: - `MonoItem::to_string` is used in `-Z print-mono-items` and therefore affects the output of all codegen-units tests. - `DefPathBasedNames` was used in `librustc_codegen_llvm/type_of.rs` with `LLVMStructCreateNamed` and that'll now get different values, but this should result in no functional change.

…ed() These are unsafe variants of the non-unchecked functions and don't do any bounds checking. For the time being these are not public and only a preparation for the following commit. Making it public and stabilization can follow later and be discussed in rust-lang#76014 .

LLVM can't figure out in
let rem = self.len() % chunk_size;
let len = self.len() - rem;
let (fst, snd) = self.split_at(len);
and
let rem = self.len() % chunk_size;
let (fst, snd) = self.split_at(rem);
that the index passed to split_at() is smaller than the slice length and
adds a bounds check plus panic for it.
Apart from removing the overhead of the bounds check this also allows
LLVM to optimize code around the ChunksExact iterator better.

…te-pretty-printer, r=eddyb ty: remove obsolete pretty printer Fixes rust-lang#61139. This PR removes the obsolete printer and replaces all uses of it with `FmtPrinter`. Of the replaced uses, all but one use was in `debug!` logging, two cases were notable: - `MonoItem::to_string` is used in `-Z print-mono-items` and therefore affects the output of all codegen-units tests (which have been updated). - `DefPathBasedNames` was used in `librustc_codegen_llvm/type_of.rs` with `LLVMStructCreateNamed` and that'll now get different values, but nothing will break as a result of this. cc @eddyb (whom I've discussed this with)
