Rollup merge of #92589 - ChrisDenton:break-loop, r=Mark-Simulacrum
Break the loop

A missing break statement lead to an infinite loop in bootstrap.py.

I also added a short sleep so it's not constantly running at 100%. But I can remove that if it's not wanted.

Rollup merge of #92504 - dtolnay:wall, r=jackh726
Exit nonzero on rustc -Wall

Previously `rustc -Wall /dev/null` would print a paragraph explaining that `-Wall` is not a thing in Rust, but would then exit 0. I believe exiting 0 is not the right behavior. For something like `rustc --version` or `rustc --help` or `rustc -C help` the user is requesting rustc to print some information; rustc prints that information and exits 0 because what the user requested has been accomplished. In the case of `rustc -Wall path/to/main.rs`, I don't find it correct to conceptualize this as "the user requested rustc to print information about the fact that Wall doesn't exist". The user requested a particular thing, and despite rustc knowing what they probably meant and informing them about that, the thing they requested has *not* been accomplished. Thus a nonzero exit code is needed.

cg: split dwarf for crate dependencies

Fixes #81024.

- In #79570, `-Z split-dwarf-kind={none,single,split}` was replaced by `-C split-debuginfo={off,packed,unpacked}`. `-C split-debuginfo`'s packed and unpacked aren't exact parallels to single and split, respectively.

  On Unix, `-C split-debuginfo=packed` will put debuginfo in object files and package debuginfo into a DWARF package file (`.dwp`) and `-C split-debuginfo=unpacked` will put debuginfo in dwarf object files and won't package it.

  In the initial implementation of Split DWARF, split mode wrote sections which did not require relocation into a DWARF object (`.dwo`) file which was ignored by the linker and then packaged those DWARF objects into DWARF packages (`.dwp`). In single mode, sections which did not require relocation were written into object files but ignored by the linker and were not packaged. However, both split and single modes could be packaged or not, the primary difference in behaviour was where the debuginfo sections that did not require link-time relocation were written (in a DWARF object or the object file).

  In the first commit of this PR, I re-introduce a `-Z split-dwarf-kind` flag, which can be used to pick between split and single modes when `-C split-debuginfo` is used to enable Split DWARF (either packed or unpacked).
- Split DWARF packaging requires all of the object files to exist, including those in dependencies. ~~Therefore, the second commit of this PR makes rustc keep all objects or dwarf objects for unpacked mode and if the crate is a dependency in packed mode (determined by heuristic: if no linking is taking place), then objects or dwarf objects are kept. Objects are kept if `-Z split-dwarf-kind` is `SplitDwarfKind::Single`, and dwarf objects if `SplitDwarfKind::Split`.~~

  ~~There are other approaches that could be taken to supporting packed Split DWARF with crate dependencies but this seemed like the least complicated and was contained to only rustc. Other potential approaches are described in https://github.com/rust-lang/rust/issues/81024#issuecomment-760478223, I'm happy to change the approach I've taken here if it isn't what we're looking for.~~ See https://github.com/rust-lang/rust/pull/89819#issuecomment-985671867 for the current approach.
- ~~There's still a dependency on `llvm-dwp` after this change, which [we probably want to move away from](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/llvm-dwp.20is.20not.20recommended) but that seems out-of-scope for this PR. Ideally, Split DWARF (in packed or unpacked modes) will be usable on nightly after this lands. If there aren't any bugs reported then it's possible we could allow Split DWARF to be used on stable after this change, it depends whether or not switching away from `llvm-dwp` later would break any guarantees, or whether we'd want to change how we handle this cross-crate case in future.~~ See https://github.com/rust-lang/rust/pull/89819#issuecomment-985671867.

Fix rustdoc::private_doc_tests lint for public re-exported items

Closes #72081

This involves changing the lint to check the access level is exported, rather than public.
The [exported access level](e91ad5fc62/compiler/rustc_middle/src/middle/privacy.rs (L24)) accounts for public items and items accessible to other crates with the help of `pub use` re-exports.
The pattern of re-exporting public items from a private module is usage seen in a number of popular crates.

2dc1a8a779 cg: use thorin instead of llvm-dwp
`thorin` is a Rust implementation of a DWARF packaging utility that
supports reading DWARF objects from archive files (i.e. rlibs) and
therefore is better suited for integration into rustc.

08ed338f56 sess/cg: re-introduce split dwarf kind
In #79570, `-Z split-dwarf-kind={none,single,split}` was replaced by `-C
split-debuginfo={off,packed,unpacked}`. `-C split-debuginfo`'s packed
and unpacked aren't exact parallels to single and split, respectively.

On Unix, `-C split-debuginfo=packed` will put debuginfo into object
files and package debuginfo into a DWARF package file (`.dwp`) and
`-C split-debuginfo=unpacked` will put debuginfo into dwarf object files
and won't package it.

In the initial implementation of Split DWARF, split mode wrote sections
which did not require relocation into a DWARF object (`.dwo`) file which
was ignored by the linker and then packaged those DWARF objects into
DWARF packages (`.dwp`). In single mode, sections which did not require
relocation were written into object files but ignored by the linker and
were not packaged. However, both split and single modes could be
packaged or not, the primary difference in behaviour was where the
debuginfo sections that did not require link-time relocation were
written (in a DWARF object or the object file).

This commit re-introduces a `-Z split-dwarf-kind` flag, which can be
used to pick between split and single modes when `-C split-debuginfo` is
used to enable Split DWARF (either packed or unpacked).

Drop guards in slice sorting derive src pointers from &mut T, which is invalidated by interior mutation in comparison

I tried to run https://github.com/rust-lang/miri-test-libstd on `alloc` with `-Zmiri-track-raw-pointers`, and got a failure on the test `slice::panic_safe`. The test failure has nothing to do with panic safety, it's from how the test tests for panic safety.

I minimized the test failure into this very silly program:
```rust
use std::cell::Cell;
use std::cmp::Ordering;

#[derive(Clone)]
struct Evil(Cell<usize>);

fn main() {
    let mut input = vec![Evil(Cell::new(0)); 3];

    // Hits the bug pattern via CopyOnDrop in core
    input.sort_unstable_by(|a, _b| {
        a.0.set(0);
        Ordering::Less
    });

    // Hits the bug pattern via InsertionHole in alloc
    input.sort_by(|_a, b| {
        b.0.set(0);
        Ordering::Less
    });
}
```

To fix this, I'm just removing the mutability/uniqueness where it wasn't required.
