I started out just removing a few instances of `HashMap` throughout rustc, but it ended up snowballing to remove the entire thing. Most uses translated to just using `@mut LinearMap` instead of `HashMap`, although I tried where possible to drop the `@mut` modifier. This ended up working out some of the time, but definitely not in the major use cases. Things got kinda weird in some cases like: * https://github.com/alexcrichton/rust/compare/mozilla:a56ec8c1342453a88be79e192a11501844375d40...alexcrichton:621b63300358cacad088ddd7f78180f29c40e66e#L39R1587 * https://github.com/alexcrichton/rust/compare/mozilla:a56ec8c1342453a88be79e192a11501844375d40...alexcrichton:621b63300358cacad088ddd7f78180f29c40e66e#L61R3760 * https://github.com/alexcrichton/rust/compare/mozilla:a56ec8c1342453a88be79e192a11501844375d40...alexcrichton:621b63300358cacad088ddd7f78180f29c40e66e#L71R917 * https://github.com/alexcrichton/rust/compare/mozilla:a56ec8c1342453a88be79e192a11501844375d40...alexcrichton:621b63300358cacad088ddd7f78180f29c40e66e#L91R127 I tried to tag them all with bugs which I thought would make them less weird, but I may have the wrong bug in a few places. These cases only came up when I tried to pass around `&mut LinearMap` instead of an `@mut LinearMap`. I also ran into a few bugs when migrating to `LinearMap`, one of which is #5521. There's another set of bugs which a00d779042fb8753c716e07b4f1aac0d5ab7bf66 addresses (all marked with `XXX`). I have a feeling they're all the same bug, but all I've been able is to reproduce them. I tried to whittle down the test cases and try to get some input which causes a failure, but I've been unable to do so. All I know is that it's vaguely related to `*T` pointers being used as `&*T` (return value of `find`). I'm not able to open a very descriptive issue, but I'll do so if there seems no other better route. I realize this is a very large pull request, so if it'd be better to split this up into multiple segments I'd be more than willing to do so. So far the tests all pass locally, although I'm sure bors will turn something up. I also don't mind keeping this up to date with rebasing. This maybe should wait until after 0.6 because it is a fairly large change... |

The Rust Programming Language
This is a compiler for Rust, including standard libraries, tools and documentation.
Installation
The Rust compiler currently must be built from a tarball, unless you are on Windows, in which case using the installer is recommended.
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, Server 2008 R2), x86 only
- Linux (various distributions), x86 and x86-64
- OSX 10.6 ("Snow Leopard") or greater, x86 and x86-64
You may find that other platforms work, but these are our "tier 1" supported build environments that are most likely to work.
Note: Windows users should read the detailed getting started notes on the wiki. Even when using the binary installer the Windows build requires a MinGW installation, the precise details of which are not discussed here.
To build from source you will also need the following prerequisite packages:
- 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
Assuming you're on a relatively modern *nix system and have met the prerequisites, something along these lines should work.
$ curl -O http://static.rust-lang.org/dist/rust-0.5.tar.gz
$ tar -xzf rust-0.5.tar.gz
$ cd rust-0.5
$ ./configure
$ make && make install
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; rustdoc, the
API-documentation tool, and rustpkg, the Rust package manager and build system.
