Promote missing_fragment_specifier to hard error
It has been deny_by_default since 2017 (and warned for some time
before that), so it seems reasonable to promote it.
The specific technical motivation to do this now is to remove a field
from `ParseSess` -- it is a global state, and global state makes
extracting libraries annoying.
Closes#40107
cmake-rs@8141f0e changed the logic for handling asm compiler flags.
This change was pulled in with the cmake 0.1.42 -> 0.1.44 update.
This introduced two new flags to the LLVM build, breaking it:
"-DCMAKE_ASM_FLAGS= -ffunction-sections -fdata-sections -fPIC -m64"
"-DCMAKE_ASM_COMPILER=/usr/bin/cc"
This patch should resolve the breakage by handling it in bootstrap.
Avoid showing this error where it doesn't make sense by not assuming
"and" and "or" were intended to mean "&&" and "||" until after we decide
to continue parsing input as an associative expression.
Note that the decision of whether or not to continue parsing input as an
associative expression doesn't actually depend on this assumption.
Fixes#75599
Don't use `dep_graph.with_ignore` when encoding fn param names
The call to `with_ignore` was added years ago, and should no longer be
necessary with the modern incremental query infrastructure.
I also removed a related FIXME comment for issue #38501, which was
closed months ago.
treeify depends on an outdated version of clap, which will fail to compile
when we promote missing_fragment_specifier future compat lint to
error (ie, old clap contains code that shouldn't have compiled in the
first place).
Additionally, this crate seem tiny relative to other crates we are
testing here, so it seems like it doesn't provide that much additional
confidence.
The same happens with tokei project, but it is an actively maintained
one, so we can just upgrade it to a version from 2018, where clap was
upgraded.
Suppress verbose MIR comments for trivial types
Addresses #74508
This is my first contribution to the Rust project! Please let me know if anything needs revising, I'm happy to make changes.

librustc_metadata::locator: Properly detect file type.
Make sure to test file types against the non-canonicalized name to
avoid detecting the wrong type. Some systems save build artifacts
into associate file stores that do not preserve extensions, and
then link to those using conventionally-named symbolic links, that
are the arguments to `rustc` et al. If we canonicalize before
testing the type, we resolve the symlink, the extension is
lost and we might treat rlibs and rmetas as dylibs.
The fix is to tntroduce a temporary to hold the canonicalized name,
compare against the non-canonical name, and add a comment
explaining what's going on for the would-be mainter who sees a
potential cleanup.

This should fix#75581.
This is my first contribution to the Rust organization. Please, feel free to tell me if I did anything wrong :)
Add explanation for `&mut self` method call when expecting `-> Self`
When a user tries to use a method as if it returned a new value of the
same type as its receiver, we will emit a type error. Try to detect this
and provide extra explanation that the method modifies the receiver
in-place.
This has confused people in the wild, like in

Allowing raw ptr dereference in const fn
Reflect on issue #75340
Discussion in previous PR #75425
## Updates
Change `UnsafetyViolationKind::General` to `UnsafetyViolationKind::GeneralAndConstFn` in check_unsafety.rs
Remove `unsafe` in min_const_fn_unsafe_bad.rs
Bless min_const_fn
Add the test case from issue 75340
***
Sorry for the chaos. I messed up and ended up deleting the repo in the last PR. I have to create a new PR for the new repo. I will make a feature branch next time. I will edit the old PR once I receive the commends.
@RalfJung Thank you all for your replies. They are helpful!

Move to intra doc links for ascii.rs and panic.rs
Helps with #75080.
@rustbot modify labels: T-doc, A-intra-doc-links, T-rustdoc
I also updated the doc to fix the wording in `AsciiExt` since it is now deprecated.
The two file are small changes so I bundled them together.
Some links could not be changed to make them work, I believe those are known issues with primitive types.
Add `as_uninit`-like methods to pointer types and unify documentation of `as_ref` methods
This adds a convenient method to retrieve a `&(mut) [MaybeUninit<T>]` from slice pointers (`*const [T]`, `*mut [T]`, `NonNull<[T]>`). See also https://github.com/rust-lang/wg-allocators/issues/66#issuecomment-671789105.
~I'll add a tracking issue as soon as it's reviewed and CI passed.~

attempt to improve span_label docs
I was still confused by the `span_label` docs, so I did some more digging. However, this needs careful checking as I have no idea if any of this is correct.
