588f83324d Rollup merge of #44135 - GuillaumeGomez:fix-css-links, r=QuietMisdreavus
Fix invalid linker position

Fixes #44120.

Result isn't "optimal" though because there are spaces at the end of some lines.

Fail ./x.py on invalid command

Make the ./x.py script fail when run with an invalid command, like:

```
./x.py nonsense
```

This helps in case of chaining multiple runs, eg.:

```
./x.py biuld && ./x.py test
```

I plan to make the same change in compiletest-rs, to have some documentation in [the docs](https://docs.rs/compiletest_rs/0.2.9/compiletest_rs/common/struct.Config.html).

30907e1a27 Rollup merge of #44117 - frewsxcv:frewsxcv-to-socket-addrs-examples, r=QuietMisdreavus
Rewrite `std::net::ToSocketAddrs` doc examples.

in particular:

* show how to create an iterator that yields multiple socket addresses
* show more failing scenarios

done this as preliminary work while investigating https://github.com/rust-lang/rust/issues/22569

note: i haven't run doc tests on my machine for this, so would be good to confirm CI passes before approving

ba304b96c4 Rollup merge of #44076 - RalfJung:src, r=alexcrichton
include Cargo.{toml,lock} in rust-src tarball

The lock file is interesting because e.g. xargo could use it to build libstd against the same dependencies that were used for the main build. More generally speaking, just documenting in this form which exact dependencies should be used IMHO makes lots of sense.

I added the Cargo.toml mostly because having the lock without the toml feels odd. Of course, the toml contains references to paths that don't actually exist in the rust-src tarball. Not sure if that is considered a problem.

b1fff23f60 Rollup merge of #43918 - mystor:rustdoc-pound, r=QuietMisdreavus
Don't highlight # which does not start an attribute in rustdoc

Currently when we highlight some macros for rustdoc (e.g. `quote!` from https://github.com/dtolnay/quote), we get really bad syntax highlighting, because we assume that every token between a `#` character and the next `]` in the source must be an attribute.

This patch improves that highlighting behavior to instead only highlight after finding the `[` token after the `#` token.

(NOTE: I've only run this patch against https://github.com/nrc/rustdoc-highlight so if it doesn't build on travis that's why - I don't have a recent rustc build on this laptop)

630e02f25b Auto merge of #43648 - RalfJung:jemalloc-debug, r=alexcrichton
Fix alloc_jemalloc debug feature

At least, I think that's how it should be.  'debug' is how the feature is called in liballoc_jemalloc/Cargo.toml and libstd/Cargo.toml. I verified this by making the build script panic rather than adding `--enable-debug`, and without this PR, the panic does not occur even when I set `debug-jemalloc = true` in config.toml. With the PR, the panic occurs as expected.

However, I actually have no idea what I am doing here.

faf477a8c2 Auto merge of #44111 - zackmdavis:feature_attr_error_span, r=nikomatsakis
feature error span on attribute for fn_must_use, SIMD/align reprs, macro reëxport

There were several feature-gated attributes for which the feature-not-available
error spans would point to the item annotated with the gated attribute, when it
would make more sense for the span to point to the attribute itself: if the
attribute is removed, the function/struct/_&c._ likely still makes sense and the
program will compile. (Note that we decline to make the analogous change for
the `main`, `start`, and `plugin_registrar` features, for in those cases it
makes sense for the span to implicate the entire function, of which there is
little hope of using without the gated attribute.)

std: Mark allocation functions as nounwind

This commit flags all allocation-related functions in liballoc as "this can't

The documentation on the trait was updated with such a restriction (they can't
panic) as well as some other words about the relative instability about
implementing a bullet-proof allocator.

clear out projection subobligations after they are processed

After a projection was processed, its derived subobligations no longer
need any processing when encountered, and can be removed. This improves
the status of #43787.

This is actually complementary to #43938 - that PR fixes selection
caching (and @remram44's example, which "accidentally" worked because of
the buggy projection caching) while this PR fixes projection caching.

Generator support

This adds experimental support for generators intended to land once https://github.com/rust-lang/rfcs/pull/2033 is approved.

This is not yet ready to be merged. Things to do:
- [x] Make closure arguments on generators an error
- [x] Spot FIXMEs
- [x] Pass make tidy
- [x] Write tests
- [x] Document the current syntax and semantics for generators somewhere
- [x] Use proper error message numbers
- [x] ~~Make the implicit argument type default to `()`~~

adfebed9db Explicitly run perl for OpenSSL Configure
OpenSSL's Configure script is missing a shebang. On some platforms,
execve falls back to execution with the shell. Some other platforms,
like musl, will fail with an exec format error. Avoid this by calling
perl explicitly (since it's a perl script).

Clarify that VecDeque::swap can panic

The previous documentation mentioned this, but ambiguously used the term "fail".

This clarifies that the function will panic if the index is out of bounds, instead of silently failing and not doing anything.

If there's anything else I can do to improve this PR, I'd be happy to do so! Just saw this when reading through the docs in passing - it was slightly unclear what "fail" meant.
