When trying to build against a newer, local LLVM version it might be
preferable to have a flag to disable the LLVM version check instead of
having to modify the configure script.
Fixes #21998

Add error message (i.e. do not ICE) when moving out of unsafe pointers.
Fix #20801.
|
|
This is to allow for use cases like sending a raw pointer slice across thread boundaries.

* Remove type parameters from `IteratorExt::cloned`
* Rename `IntoIterator::Iter` to `IntoIterator::IntoIter`
* Mark `IntoIterator::into_iter` as stable (but not the trait, only the method).

Based off https://github.com/rust-lang/rust/pull/21843, it looks like the syntax in the Closures guide is outdated.

Fixes #22070.
Fixes #19372.

Crate types from multiple sources appear to be deduplicated properly, but not
deduplicated if they come from the command line arguments. At worst, this used
to cause compiler failures when `--crate-type=lib,rlib` (the same as
`--crate-type=rlib,rlib`, at least at the time of this commit) is provided and
generate the output multiple times otherwise.

Replace links to `../index.html` with `index.html` as they are linking to the `std` module and not `std::cell` as intended.
See for example [RefCell documentation](http://doc.rust-lang.org/std/cell/struct.RefCell.html).

I started to write up some docs on this, and then realized I was just repeating http://huonw.github.io/blog/2015/01/peeking-inside-trait-objects/ but worse. @huonw previously said that we can use this content if we wanted, so I made some tweaks and integrated it into the book.

Fixes #22091
I'm not sure how to write a test for this. An ICE happens with spans that start near (after?) a null character or some other zero-width unicode character.

The fallback font for a serif font should also be serif, not sans serif.
|
|
Rename several remaining `Show`s to Debug, `String`s to Display (mostly in comments and docs).
Update reference.md:
- derive() no longer supports Zero trait
- derive() now supports Copy trait
|

- c-link-to-rust-staticlib: use `EXTRACFLAGS` defined by tools.mk for
choose the good libraries to link to.
tools.mk define a variable `EXTRACFLAGS` that contains the needed library per target. So it is better to use it, instead of duplicate the code here. I keep the `ifndef IS_WINDOWS` has tools.mk define something for WINDOWS... so I don't change things that I couldn't test.
- no-stack-check: disabled for openbsd (no segmented stacks here)
- symbols-are-reasonable: use portable grep pattern
- target-specs: use POSIX form for options when invoking grep
- use-extern-for-plugins: disable as OpenBSD only support x86_64 for now

This was correct in the EBNF, but not in the prose (which seems to have
been copied-and-pasted from regular string literals).
|
|
So many warnings
|
|
When self.start > self.end, these iterators simply return None,
so we adjust the size_hint to just return zero in this case.
Certain optimizations can be implemented in and outside libstd if we
know we can trust the size_hint for all inputs to for example
Range<usize>.
This corrects the ExactSizeIterator implementations, which IMO were
unsound and incorrect previously, since they allowed a range like (2..1)
to return a size_hint of -1us in when debug assertions are turned off.

- add namespace
- add function parens

No point sending people to a page which just says "this is now part of
the Rust book" (that page being http://doc.rust-lang.org/rustdoc.html).

Given `<expr> as Box<Trait>`, infer that `Box<_>` is expected type for `<expr>`.
This is useful for addressing fallout from newly proposed box protocol; see #22006 for examples of such fallout, much of which will be unnecessary with this fix.

Add `QPath` construction support to `ExtCtxt`. Allows compiler plugins to generate calls with UFCS.

Simplify cache selection by just using the local cache whenever there
are any where-clauses at all. This seems to be the simplest possible
rule and will (hopefully!) put an end to these annoying "cache leak"
bugs. Fixes #22019.

```rust
#[plugin] #[no_link] extern crate bleh;
```
becomes a crate attribute
```rust
#![plugin(bleh)]
```
The feature gate is still required.
It's almost never correct to link a plugin into the resulting library / executable, because it will bring all of libsyntax and librustc with it. However if you really want this behavior, you can get it with a separate `extern crate` item in addition to the `plugin` attribute.
Fixes #21043.
Fixes #20769.

This commit is an implementation of [RFC 739][rfc] which adds a new `std::fs`
module to the standard library. This module provides much of the same
functionality as `std::old_io::fs` but it has many tweaked APIs as well as uses
the new `std::path` module.
