This doesn't seem to be necessary anymore, although I don't know
at which point or why that changed.
Forcing -O1 makes some tests fail under NewPM, because NewPM also
performs inlining at -O1, so it ends up performing much more
optimization in practice than before.
This causes an assertion failure under NewPM, because it also ends
up disabling the NameAnonGlobals pass.
Instead pass -Copt-level=0 to disable optimizations. If that should
be insufficient, we can use -C no-prepopulate-passes.

rustdoc: Link to the docs on namespaces when an unknown disambiguator is found
This was reverted in https://github.com/rust-lang/rust/pull/84950; this re-lands the changes, but without different behavior depending on the channel.

Don't stop running rustdoc-gui tests at first failure
I just realized that before this PR, the rustdoc-gui test suite was stopping at the first failure, which isn't very convenient. All tests are now running and if one failed, it returns an error at the end once all tests have run.

Remove SpanInterner::get
- It's used exactly once, so it's trivial to replace
- It doesn't match the normal convention for containers: normally
`get()` returns an option and indexing panics. Instead `SpanInterner::get()` panics
and there's no indexing operation available.
Improve diagnostics for functions in `struct` definitions
Tries to implement #76421.
This is probably going to need unit tests, but I wanted to hear from review all the cases tests should cover.
I'd like to follow up with the "mechanically applicable suggestion here that adds an impl block" step, but I'd need guidance. My idea for now would be to try to parse a function, and if that succeeds, create a dummy `ast::Item` impl block to then format it using `pprust`. Would that be a viable approach? Is there a better alternative?
r? `@matklad` cc `@estebank`
fork fails there. The failure message is confusing: so c.status()
returns an Err, the closure panics, and the test thinks the panic was
propagated from inside the child.

Rearrange SGX split module files
In #75979 several inlined modules were split out into multiple files.
This PR keeps the multiple files but moves a few things around to
organize things in a coherent way.
rustc: Support Rust-specific features in -Ctarget-feature
Since the beginning of time the `-Ctarget-feature` flag on the command
line has largely been passed unmodified to LLVM. Afterwards, though, the
`#[target_feature]` attribute was stabilized and some of the names in
this attribute do not match the corresponding LLVM name. This is because
Rust doesn't always want to stabilize the exact feature name in LLVM for
the equivalent functionality in Rust. This creates a situation, however,
where in Rust you'd write:
#[target_feature(enable = "pclmulqdq")]
unsafe fn foo() {
// ...
}
but on the command line you would write:
RUSTFLAGS="-Ctarget-feature=+pclmul" cargo build --release
This difference is somewhat odd to deal with if you're a newcomer and
the situation may be made worse with upcoming features like [WebAssembly
SIMD](https://github.com/rust-lang/rust/issues/74372) which may be more
prevalent.
This commit implements a mapping to translate requests via
`-Ctarget-feature` through the same name-mapping functionality that's
present for attributes in Rust going to LLVM. This means that
`+pclmulqdq` will work on x86 targets where as previously it did not.
I've attempted to keep this backwards-compatible where the compiler will
just opportunistically attempt to remap features found in
`-Ctarget-feature`, but if there's something it doesn't understand it
gets passed unmodified to LLVM just as it was before.
rename LLVM target for RustyHermit
- RustyHermit is a library operating system, where the user-
and the kernel-space use the same target
- by a mistake a previous patch changes the target to an incorect value
- this merge request revert the previous changes
Cleanup of `wasm`
Some more cleanup of `sys`, this time `wasm`
- Reuse `unsupported::args` (functionally equivalent implementation, just an empty iterator).
- Split out `atomics` implementation of `wasm::thread`, the non-`atomics` implementation is reused from `unsupported`.
- Move all of the `atomics` code to a separate directory `wasm/atomics`.

Unify rustc and rustdoc parsing of `cfg()`
This extracts a new `parse_cfg` function that's used between both.
- Treat `#[doc(cfg(x), cfg(y))]` the same as `#[doc(cfg(x)]
#[doc(cfg(y))]`. Previously it would be completely ignored.
- Treat `#[doc(inline, cfg(x))]` the same as `#[doc(inline)]
#[doc(cfg(x))]`. Previously, the cfg would be ignored.
- Pass the cfg predicate through to rustc_expand to be validated
Technically this is a breaking change, but doc_cfg is still nightly so I don't think it matters.
Fixes https://github.com/rust-lang/rust/issues/84437.
