- Clarify CAS availability (rust-embedded/book#273)
Update with status for various NetBSD ports.
The NetBSD ports of rust to aarch64, armv7*, i686, and powerpc**
all both build and run. Status is as of rust 1.47.0.
*) Natively requires repeated successive build attempts (`rustc` is
such a resource pig VM-consumption-wise), or run in a chroot
on an aarch64 host where the available VM space is 4GB instead
of the native 2GB.
**) Powerpc either requires `-latomic` in a directory searched by
default by `ld` or to be built within pkgsrc which has a patch and
support package to tackle this issue.
Validate lint docs separately.
This addresses some concerns raised in https://github.com/rust-lang/rust/pull/76549#issuecomment-727638552 about errors with the lint docs being confusing and cumbersome. Errors from validating the lint documentation were being generated during `x.py doc` (and `x.py dist`), since extraction and validation are being done in a single step. This changes it so that extraction and validation are separated, so that `x.py doc` will not error if there is a validation problem, and tests are moved to `x.py test src/tools/lint-docs`.
This includes the following changes:
* Separate validation to `x.py test`.
* Added some more documentation on how to more easily modify and test the docs.
* Added more help to the error messages to hopefully provide more information on how to fix things.
The first commit just moves the code around, so you may consider looking at the other commits for a smaller diff.
Remove const_fn_feature_flags test
## Overview
Helps with #76268
I found `const_fn_feature_flags` is targeting feature-gate and remove it.

Stop adding '*' at the end of slice and str typenames for MSVC case
When computing debug info for MSVC debuggers, Rust compiler emits C++ style type names for compatibility with .natvis visualizers. All Ref types are treated as equivalences of C++ pointers in this process, and, as a result, their type names end with a '\*'. Since Slice and Str are treated as Ref by the compiler, their type names also end with a '\*'. This causes the .natvis engine for WinDbg fails to display data of Slice and Str objects. We addressed this problem simply by removing the '*' at the end of type names for Slice and Str types.
Debug info in WinDbg before the fix:
Debug info in WinDbg after the fix:
This change has also been tested with debuggers for Visual Studio, VS Code C++ and VS Code LLDB to make sure that it does not affect the behavior of other kinds of debugger.
Make keyboard interactions in the settings menu more pleasant
#78868 improved the keyboard interactions with the settings page. This PR goes a bit further by allowing more than just "space" to toggle the checkboxes.

Add built-in support for the armv5te-unknown-linux-uclibcgnueabi target
Hi!
I'd like to add built-in support for the `armv5te-unknown-linux-uclibcgnueabi` target. It's a pretty common target used by many devices like routers and IP cameras. It's mostly a copy-paste of `armv5te-unknown-linux-gnueabi`. I've tested it on a quite complex application that uses tokio, openssl and a lot of other stuff and everything seems to be working fine.
I'm not sure about the `post_link_args` but the point is that my linker fails when `-ldl` isn't specified. Maybe there is a better place where to put this option...
It's my first contribution to Rust itself, so feel free to wash my head 😄
_Note: The app mentioned above was built with this in my `.cargo/config`:_
```
[unstable]
build-std = ["core", "std", "alloc", "proc_macro", "panic_abort"]
build-std-features = ["panic_immediate_abort"]
```
More intra doc links
Helps with #75080.
I did a commit by group of file, I can squash if wanted.
`@rustbot` modify labels: T-doc, A-intra-doc-links
r? `@jyn514`
This printed several hundred lines each time rustdoc was run, almost all
of which rounded to 0.000. Since this isn't useful info, don't print it
everywhere, so other perf info is easier to read.

This checks the error code returned by `dsymutil` and warns if it failed. It
also provides the stdout and stderr logs from `dsymutil`, similar to the native
linker step.
Fixes https://github.com/rust-lang/rust/issues/78770
Fix intra-doc links for `Self` on cross-crate items and primitives
- Remove the difference between `parent_item` and `current_item`; these
should never have been different.
- Remove `current_item` from `resolve` and `variant_field` so that
`Self` is only substituted in one place at the very start.
- Resolve the current item as a `DefId`, not a `HirId`. This is what
actually fixed the bug.
Hacks:
- `clean` uses `TypedefItem` when it _really_ should be
`AssociatedTypeItem`. I tried fixing this without success and hacked
around it instead (see comments)
- This second-guesses the `to_string()` impl since it wants
fully-qualified paths. Possibly there's a better way to do this.
Update error to reflect that integer literals can have float suffixes
For example, `1` is parsed as an integer literal, but it can be turned
into a float with the suffix `f32`. Now the error calls them "numeric
literals" and notes that you can add a float suffix since they can be
either integers or floats.
