032ea41e99 book/ffi: nullable pointer, libc cleanups
Expand the "nullable pointer optimization" section with a code example.

Change examples to use std::os::raw instead of libc, when applicable.

2dbf00e2bb Only export #[no_mangle] extern symbols during LTO
Previously, all extern symbols were exported even when performing LTO.
Now, we only export symbols that are also marked #[no_mangle].

Fixes #34985

54c61ff959 librustc_back: filter targets for only valid ones
Since we can know which targets are instantiable on a particular host,
it does not make sense to list invalid targets in the target print code.
Filter the list of targets to only include the targets that can be
instantiated.

bd194a77d5 librustc_back: json tests for builtin targets
Expand the supported_targets!() macro to also generate a set of
JSON encode/decode tests to verify that the parser will encode
and decode all of the fields needed for all of the builtin targets.
Additionally, add PartialEq to Target and TargetOptions in support
of the tests.

eafecbf868 librustc_back: convert fn target() to return Result
Change all the target generation functions to return a Result<Target,
String> so that targets that are unable to be instantiated can be
expressed as an Err instead of a panic!(). This should improve #33497 as
well.

c7b6ed27bc librustc_back: add ToJson trait to Target
Target's can already be built up from JSON files as well as built into
librustc_back so this adds the ability to convert any Target back into
JSON.

9c83fa41b0 librustc_back: expose all target options via JSON
Not all TargetOptions are exposed via the JSON interface to create
different targets. This exposes all the missing items and reorders them
to match the structure so that it is easier in the future to identify
missing items.

29abe5ec71 Auto merge of #34856 - jseyfried:refactor_reset_tls, r=nrc
Avoid reseting the thread local interner at the beginning of `phase_1_parse_input`

The thread local interner is used before `phase_1_parse_input` to create `InternedString`s, which currently wrap `Rc<String>`s. Once `InternedString` is refactored to be an interned string id (like `Name`), resetting will invalidate everything that was interned before `phase_1_parse_input`.

The resets were only useful for the `rusti` project, which can now use `driver::reset_thread_local_state`.

ac73335f2f implement From<Vec<char>> and From<&'a [char]> for String
Though there are ways to convert a slice or vec of chars into a string,
it would be nice to be able to just do `String::from(['a', 'b', 'c'])`,
so this PR implements `From<Vec<char>>` and `From<&'a [char]>` for
String.

fix built-in target detection

previously the logic was accepting wrong triples (like
`x86_64_unknown-linux-musl`) as valid ones (like `x86_64-unknown-linux-musl`) if
they contained an underscore instead of a dash.

fixes #33329

I wanted to use a compile-fail test at first. But, you can't pass an extra `--target` flag to `rustc` for those because they already call `rustc --target $HOST` so you get a `error: Option 'target' given more than once.`. The run-make test used here works fine though.

422ebd5328 Auto merge of #33312 - Byron:double-ended-iterator-for-args, r=alexcrichton
DoubleEndedIterator for Args

This PR implements the DoubleEndedIterator trait for the `std::env::Args[Os]` structure, as well
as the internal implementations.

It is primarily motivated by me, as I happened to implement a simple `reversor` program many times
now, which so far had to use code like this:

```Rust
for arg in std::env::args().skip(1).collect::<Vec<_>>().iter().rev() {}
```

... even though I would have loved to do this instead:

```Rust
for arg in std::env::args().skip(1).rev() {}
```

The latter is more natural, and I did not find a reason for not implementing it.
After all, on every system, the number of arguments passed to the program are known
at runtime.

To my mind, it follows KISS, and does not try to be smart at all. Also, there are no unit-tests,
primarily as I did not find any existing tests for the `Args` struct either.

The windows implementation is basically a copy-pasted variant of the `next()` method implementation,
and I could imagine sharing most of the code instead. Actually I would be happy if the reviewer would
ask for it.

std: Ignore tests where threads outlive main

rest of the program is exiting causes Windows to hang (#20704). That's what was
happening in this test so let's just not run this test any more.

1aa8dad854 DoubleEndedIterator for Args
The number of arguments given to a process is always known, which
makes implementing DoubleEndedIterator possible.

That way, the Iterator::rev() method becomes usable, among others.

Signed-off-by: Sebastian Thiel <byronimo@gmail.com>

Tidy for DoubleEndedIterator

I chose to not create a new feature for it, even though
technically, this makes me lie about the original availability
of the implementation.

Verify with @alexchrichton

Setup feature flag for new std::env::Args iterators

Add test for Args reverse iterator

It's somewhat depending on the input of the test program,
but made in such a way that should be somewhat flexible to changes
to the way it is called.

Deduplicate windows ArgsOS code for DEI

DEI = DoubleEndedIterator

Move env::args().rev() test to run-pass

It must be controlling it's arguments for full isolation.

Remove superfluous feature name

Assert all arguments returned by env::args().rev()

Let's be very sure it works as we expect, why take chances.

Fix rval of os_string_from_ptr

A trait cannot be returned, but only the corresponding object.

Deref pointers to actually operate on the argument

Put unsafe to correct location
