Michael Woerister 302486e49b debuginfo: Make sure that all calls to drop glue are associated with debug locations. This commit makes rustc emit debug locations for all call and invoke statements in LLVM IR, if they are contained within a function that debuginfo is enabled for. This is important because LLVM does not handle the case where a function body containing debuginfo is inlined into another function with debuginfo, but the inlined call statement does not have a debug location. In this case, LLVM will not know where (in terms of source code coordinates) the function was inlined to and we end up with some statements still linked to the source locations in there original, non-inlined function without any indication that they are indeed an inline-copy. Later, when generating DWARF from the IR, LLVM will interpret this as corrupt IR and abort. Unfortunately, the undesirable case described above can still occur when using LTO. If there is a crate compiled without debuginfo calling into a crate compiled with debuginfo, we again end up with the conditions triggering the error. This is why some LTO tests still fail with the dreaded assertion, if the standard library was built with debuginfo enabled. That is, `RUSTFLAGS_STAGE2=-g make rustc-stage2` will succeed but `RUSTFLAGS_STAGE2=-g make check` will still fail after this commit has been merged. This is a problem that has to be dealt with separately. Fixes #17201 Fixes #15816 Fixes #15156		2014-09-25 14:17:14 +02:00

The Rust Programming Language

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

Quick Start

Download a binary installer for your platform.
Read the guide.
Enjoy!

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

Building from Source

Make sure you have installed the dependencies:
- g++ 4.7 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
- git
Download and build Rust:

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

To build from the tarball do:
```
 $ curl -O https://static.rust-lang.org/dist/rust-nightly.tar.gz
 $ tar -xzf rust-nightly.tar.gz
 $ cd rust-nightly
```
Or to build from the repo do:
```
 $ git clone https://github.com/rust-lang/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.
Read the guide.
Enjoy!

Building on Windows

To easily build on windows we can use MSYS2:

Grab the latest MSYS2 installer and go through the installer.
Now from the MSYS2 terminal we want to install the mingw64 toolchain and the other tools we need.
```
 $ pacman -S mingw-w64-i686-toolchain
 $ pacman -S base-devel
```
With that now start mingw32_shell.bat from where you installed MSYS2 (i.e. C:\msys).
From there just navigate to where you have Rust's source code, configure and build it:
```
 $ ./configure
 $ make && make install
```

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.

Getting help and getting involved

The Rust community congregates in a few places:

StackOverflow - Get help here.
/r/rust - General discussion.
discuss.rust-lang.org - For development of the Rust language itself.
