- Make sure the mobile-topbar doesn't overflow its height if the user
sets a bigger font.
- Make sure the sidebar can be scrolled all the way to the bottom by
shortening it to accommodate the mobile-topbar.
- Make the item name in the mobile-topbar clickable to go to the top of
the page.
- Remove excess padding sidebar in mobile mode.
When `DirEntry::file_type` fails to match a known `d_type`, we should
fall back to `DirEntry::metadata` instead of a bare `lstat`, because
this is faster and more reliable on targets with `fstatat`.
Rename _args -> args in format_args expansion
As observed in https://github.com/rust-lang/rust/pull/91359#discussion_r786058960, prior to that PR this variable was sometimes never used, such as in the case of:
```rust
println!("");
// used to expand to:
::std::io::_print(
::core::fmt::Arguments::new_v1(
&["\n"],
&match () {
_args => [],
},
),
);
```
so the leading underscore in `_args` was used to suppress an unused variable lint. However after #91359 the variable is always used when present, as the unused case would instead expand to:
```rust
::std::io::_print(::core::fmt::Arguments::new_v1(&["\n"], &[]));
```
fs: Don't copy d_name from struct dirent
The dirent returned from readdir() is only guaranteed to be valid for
d_reclen bytes on common platforms. Since we copy the name separately
anyway, we can copy everything except d_name into DirEntry::entry.
Fixes#93384.
rustdoc: load the set of in-scope traits for modules with no docstring
Fixes#93428
This fix is a response to a couple of special cases related to the `module_id`, which is eventually used for trait candidates:
* The module id is always set to the current crate, when checking `crate::`.
Normally, the set of in-scope traits would be set in `load_links_in_attrs`, but if there are no doc comments, then that loop will never run.
* the module id is set to the parent module, when resolving a module that is spelled like this:
// Notice how we use an outlined doc comment here!
// [`Test::my_fn`]
mod something {
}
As with the above problem with `crate::`, we need to make sure the module gets its traits in scope resolved, even if it has no doc comments of its own.
Move unstable is_{arch}_feature_detected! macros to std::arch
These macros are unstable, except for `is_x86_feature_detected` which is still exported from the crate root for backwards-compatibility.
This should unblock the stabilization of `is_aarch64_feature_detected`.
r? ```@m-ou-se```
Add note suggesting that predicate may be satisfied, but is not `const`
Not sure if we should be printing this in addition to, or perhaps _instead_ of the help message:
```
help: the trait `~const Add` is not implemented for `NonConstAdd`
```
Also added `ParamEnv::is_const` and `PolyTraitPredicate::is_const_if_const` and, in a separate commit, used those in other places instead of `== hir::Constness::Const`, etc.

Fixes#93384.
remove unused `jemallocator` crate
When it was noticed that the rustc binary wasn't actually using jemalloc via `#[global_allocator]` and that was removed, the dependency remained.
Tests pass locally with a `jemalloc = true` build, but I'll trigger a try build to ensure I haven't missed an edge-case somewhere.
r? ```@ghost``` until that completes
kmc-solid: Implement `net::FileDesc::duplicate`
This PR implements `std::sys::solid::net::FileDesc::duplicate`, which was accidentally left out when this target was added by #86191.
Add `intrinsics::const_deallocate`
Tracking issue: #79597
Related: #91884
This allows deallocation of a memory allocated by `intrinsics::const_allocate`. At the moment, this can be only used to reduce memory usage, but in the future this may be useful to detect memory leaks (If an allocated memory remains after evaluation, raise an error...?).
Bump libc and fix remove_dir_all on Fuchsia after CVE fix
With the previous `is_dir` impl, we would attempt to unlink
a directory in the None branch, but Fuchsia supports returning
ENOTEMPTY from unlinkat() without the AT_REMOVEDIR flag because
we don't currently differentiate unlinking files and directories
by default.
On the Fuchsia side I've opened https://fxbug.dev/92273 to discuss
whether this is the correct behavior, but it doesn't seem like
addressing the error code is necessary to make our tests happy.
Depends on https://github.com/rust-lang/libc/pull/2654 since we
apparently haven't needed to reference DT_UNKNOWN before this.
