bors d42521aa92 auto merge of #11866 : alexcrichton/rust/atomic-u64, r=brson 
Let's try this again.

This is an implementation of mutexes which I believe is free from undefined behavior of OS mutexes (the pitfall of the previous implementation).

This implementation is not ideal. There's a yield-loop spot, and it's not particularly fair with respect to lockers who steal without going through the normal code paths. That being said, I believe that this is a correct implementation which is a stepping stone to move from.

I haven't done rigorous benchmarking of this mutex, but preliminary results show that it's about 25% slower in the uncontended case on linux (same runtime on OSX), and it's actually faster than a pthreads mutex on high contention (again, not rigorous benchmarking, I just saw these numbers come up).

The Rust Programming Language

This is a compiler for Rust, including standard libraries, tools and documentation.

Quick Start

Windows

  1. Download and use the installer and MinGW.
  2. Read the tutorial.
  3. Enjoy!

Note: Windows users can read the detailed getting started notes on the wiki.

Linux / OS X

  1. Make sure you have installed the dependencies:

    • g++ 4.4 or clang++ 3.x
    • python 2.6 or later (but not 3.x)
    • perl 5.0 or later
    • GNU make 3.81 or later
    • curl

  2. Download and build Rust:

    You can either download a tarball or build directly from the repo.

    To build from the tarball do:

     $ curl -O http://static.rust-lang.org/dist/rust-0.9.tar.gz
 $ tar -xzf rust-0.9.tar.gz
 $ cd rust-0.9

    Or to build from the repo do:

     $ git clone https://github.com/mozilla/rust.git
 $ cd rust

    Now that you have Rust's source code, you can configure and build it:

     $ ./configure
 $ make && make install

    Note: You may need to use sudo make install if you do not normally have permission to modify the destination directory. The install locations can be adjusted by passing a --prefix argument to configure. Various other options are also supported, pass --help for more information on them.

    When complete, make install will place several programs into /usr/local/bin: rustc, the Rust compiler, and rustdoc, the API-documentation tool. system.

  3. Read the tutorial.

  4. Enjoy!

Notes

Since the Rust compiler is written in Rust, it must be built by a precompiled "snapshot" version of itself (made in an earlier state of development). As such, source builds require a connection to the Internet, to fetch snapshots, and an OS that can execute the available snapshot binaries.

Snapshot binaries are currently built and tested on several platforms:

  • Windows (7, 8, Server 2008 R2), x86 only
  • Linux (2.6.18 or later, various distributions), x86 and x86-64
  • OSX 10.7 (Lion) or greater, x86 and x86-64

You may find that other platforms work, but these are our officially supported build environments that are most likely to work.

Rust currently needs about 1.5 GiB of RAM to build without swapping; if it hits swap, it will take a very long time to build.

There is a lot more documentation in the wiki.
