Alex Crichton 62861f8797 configure: Fix gcc detection for LLVM
We have a case where 32-bit compilation accidentally requested clang when gcc
was the only one available.

Guillaume Gomez 30164c21fa Rollup merge of #37081 - p512:master, r=sfackler
Changed 0 into '0'

Right now `0` is an undefined production rule.
[Documentation following the grammar specification](https://doc.rust-lang.org/nightly/std/fmt/#sign0) strongly suggests `'0'` is meant as it is used as a character literal.

ICH: Enable some cases in trait definition hashing.

Guillaume Gomez ffa9bbf7cd Rollup merge of #37065 - nnethercote:opt-mk_printer, r=nikomatsakis
Merge `Printer::token` and `Printer::size`.

Logically, it's a vector of pairs, so might as well represent it that
way.

The commit also changes `scan_stack` so that it is initialized with the
default size, instead of the excessive `55 * linewidth` size, which it
usually doesn't get even close to reaching.

Guillaume Gomez 97e9eac8bf Rollup merge of #36997 - KillTheMule:patch-1, r=steveklabnik
Book: Be very explicit of lifetimes being descriptive

... not prescriptive. Pointed out in https://users.rust-lang.org/t/what-if-i-get-lifetimes-wrong/7535/4, which was a revelation to me and made me think this should be more clear in the book. I'm not sure if I got this entirely right or if the wording is good, but I figured a PR is more helpful than a simple issue.

r? @steveklabnik

Small Note: There's also https://github.com/rust-lang/book, should I have sent the PR there? It doesn't coincide with the online book though, so I figured it's better of here.

Guillaume Gomez 0b7fe4d67c Rollup merge of #36699 - bluss:repeat-str, r=alexcrichton
Add method str::repeat(self, usize) -> String

It is relatively simple to repeat a string n times:
`(0..n).map(|_| s).collect::<String>()`. It becomes slightly more
complicated to do it “right” (sizing the allocation up front), which
warrants a method that does it for us.

This method is useful in writing testcases, or when generating text.
`format!()` can be used to repeat single characters, but not repeating
strings like this.

Guillaume Gomez 6717dba276 Rollup merge of #36679 - QuietMisdreavus:rustdoc-line-breaks, r=steveklabnik
rustdoc: print non-self arguments of bare functions and struct methods on their own line

This change alters the formatting rustdoc uses when it creates function and struct method documentation. For bare functions, each argument is printed on its own line. For struct methods, non-self arguments are printed on their own line. In both cases, no line breaks are introduced if there are no arguments, and for struct methods, no line breaks are introduced if there is only a single self argument. This should aid readability of long function signatures and allow for greater comprehension of these functions.

I've run rustdoc with these changes on my crate egg-mode and its set of dependencies and put the result [on my server](https://shiva.icesoldier.me/doc-custom/egg_mode/). Of note, here are a few shortcut links that highlight the changes:

* [Bare function with a long signature](https://shiva.icesoldier.me/doc-custom/egg_mode/place/fn.reverse_geocode.html)
* [Struct methods, with single self argument and with self and non-self arguments](https://shiva.icesoldier.me/doc-custom/egg_mode/tweet/struct.Timeline.html#method.reset)
* [Bare functions with no arguments](https://shiva.icesoldier.me/doc-custom/rand/fn.thread_rng.html) and [struct methods with no arguments](https://shiva.icesoldier.me/doc-custom/hyper/client/struct.Client.html#method.new) are left unchanged.

This PR consists of two commits: one for bare functions and one for struct methods.

bors 6d620843f6 Auto merge of #36341 - sagebind:thread_id, r=alexcrichton
Add ThreadId for comparing threads

This adds the capability to store and compare threads with the current calling thread via a new struct, `std:🧵:ThreadId`. Addresses the need outlined in issue #21507.

This avoids the need to add any special checks to the existing thread structs and does not rely on the system to provide an identifier for a thread, since it seems that this approach is unreliable and undesirable. Instead, this simply uses a lazily-created, thread-local `usize` whose value is copied from a global atomic counter. The code should be simple enough that it should be as much reliable as the `#[thread_local]` attribute it uses (however much that is).

`ThreadId`s can be compared directly for equality and have copy semantics.

Also see these other attempts:
- rust-lang/rust#29457
- rust-lang/rust#29448
- rust-lang/rust#29447

And this in the RFC repo: rust-lang/rfcs#1435

Nicholas Nethercote b043e11de2 Avoid allocations in `Decoder::read_str`.
`opaque::Decoder::read_str` is very hot within `rustc` due to its use in
the reading of crate metadata, and it currently returns a `String`. This
commit changes it to instead return a `Cow<str>`, which avoids a heap
allocation.

This change reduces the number of calls to `malloc` by almost 10% in
some benchmarks.

This is a [breaking-change] to libserialize.
