Remove empty core::lazy and std::lazy
PR #98165 with commits 7c360dc117 and c1a2db3372 has moved all of the components of these modules into different places, namely {std,core}::sync and {std,core}::cell. The empty modules remained. As they are unstable, we can simply remove them.

rustdoc: Document effect of fundamental types
This was implemented in https://github.com/rust-lang/rust/pull/96565, but not documented. But it's a useful feature for everyone who implements own wrapper (especially wrappers-around-pointers) types, so that they can behave like pointers (and stdlib wrappers) do -- so here goes a mention in the unstable section of the rustdoc book.
(That is where I initially looked to find tricks for making my own wrapper types be transparent to documentation).
don't ICE when normalizing closure input tys
We were ICEing while rendering diagnostics because `universe_causes` is expected to track every universe created in the typeck's infcx.
`normalize_and_add_constraints` doesn't update `universe_causes`
when creating new universes, causing an ICE. Remove it!
Add spans to better track normalization constraints.
Fix couple places where `universe_causes` is not updated correctly to
track newly added universes.
Fixes#102800
~Fixess #99665~ (UPDATE: no longer true; the issue has a different failure path than when this PR was created and should be fixed by #101708, but the changes in this PR are still correct and should prevent potential future ICEs)
VS Code problem matcher are restricted to be static "regexes". You can't
create a problem matcher dynamically, and you can't use custom code in
lieu of problem matcher.
This creates a problem for rust/cargo compiler errors. They use paths
relative to the root of the Cargo workspace, but VS Code doesn't
necessary know where that root is.
Luckily, there's a way out: our current problem matcher is defined like
this:
"fileLocation": [ "autoDetect", "${workspaceRoot}" ],
That means that relative pahts would be resoleved relative to workspace
root. VS Code allows to specify a command inside `${}`. So we can plug
custom logic there to fetch Cargo's workspace root!
And that's exactly what this PR is doing!
test: run-make: skip when cross-compiling
This test fails when targeting aarch64 Android. Instead of adding yet another architecture here (and one that's increasingly more common as the host), let's replace the growing list of architectures with ignore-cross-compile.
Make the `config.src` handling for downloadable bootstrap more conservative
In particular, this supports build directories within an unrelated git repository. Fixes https://github.com/rust-lang/rust/issues/102562.
As a side effect, it will fall back to the old logic when the source directory is being built from a tarball within an unrelated git repository. However, that second case is unsupported and untested; we reserve the right to break it in the future.
`@cr1901` can you confirm this fixes your problem?
cc `@kleisauke,` I believe this will also fix your issue (although your use case still isn't supported).

`EscapeAscii` is not an `ExactSizeIterator`
Fixes#99878
Do we want/need `EscapeAscii` to be an `ExactSizeIterator`? I guess we could precompute the length of the output if so?
Fix gdb-cmd for rust-gdbgui
With https://github.com/cs01/gdbgui/pull/198, the way that gdbgui arguments were specified changed. I've tested this with program generated from `cargo new --bin` and it worked as gdbgui should.
Closes#76383.
add a few more assert_unsafe_precondition
Add debug-assertion checking for `ptr.read()`, `ptr.write(_)`, and `unreachable_unchecked.`
This is quite useful for [cargo-careful](https://github.com/RalfJung/cargo-careful).
This DOM cleanup changes the color of the triangle, from blue to black, but
since it's still a different color from the link it's next to, it should
still be noticeable.
internal: ⬆️ xflags
The main change here should be that flags are not inhereted, so
$ rust-analyzer analysis-stats . -v -v
would do what it should do
We also no longer Don\'t

It added the possibility to concatenate strings and numbers and updated the `goto` command so it doesn't stand on its own anymore.

Fix MIR inlining of asm_unwind
The MIR inlining currently doesn't handle inline asm's unwind edge correctly.
This code will cause ICE:
```rust
struct D;
impl Drop for D {
fn drop(&mut self) {}
}
#[inline(always)]
fn foo() {
let _d = D;
unsafe { std::arch::asm!("", options(may_unwind)) };
}
pub fn main() {
foo();
}
```
This PR fixes this issue. I also take the opportunity to extract common code into a method.

As discussed in #97649 `mir::CastKind::Misc` is not clear, this PR addresses that by creating a new enum variant for every valid cast.

Rewrite representability
* Improve placement of `Box` in the suggestion
* Multiple items in a cycle emit 1 error instead of an error for each item in the cycle
* Introduce `representability` query to avoid traversing an item every time it is used.
* Also introduce `params_in_repr` query to avoid traversing generic items every time it is used.
std: use futex in `Once`
Now that we have efficient locks, let's optimize the rest of `sync` as well. This PR adds a futex-based implementation for `Once`, which drastically simplifies the implementation compared to the generic version, which is provided as fallback for platforms without futex (Windows only supports them on newer versions, so it uses the fallback for now).
Instead of storing a linked list of waiters, the new implementation adds another state (`QUEUED`), which is set when there are waiting threads. These now use `futex_wait` on that state and are woken by the running thread when it finishes and notices the `QUEUED` state, thereby avoiding unnecessary calls to `futex_wake_all`.
`normalize_and_add_constraints` doesn't add entries in `universe_causes`
when creating new universes, causing an ICE. Remove it!
Add spans to track normalization constraints.
Fix couple places where `universe_causes` is not updated correctly to
track newly added universes.
