mk: Switch rustbuild to the default build system This commit switches the default build system for Rust from the makefiles to rustbuild. The rustbuild build system has been in development for almost a year now and has become quite mature over time. This commit is an implementation of the proposal on [internals] which slates deletion of the makefiles on 2017-02-02. [internals]: https://internals.rust-lang.org/t/proposal-for-promoting-rustbuild-to-official-status/4368 This commit also updates various documentation in `README.md`, `CONTRIBUTING.md`, `src/bootstrap/README.md`, and throughout the source code of rustbuild itself.

To see a full list of options, run `./configure --help`.
|
||||
|
||||
### Useful Targets
|
||||
### Building
|
||||
|
||||
Some common make targets are:
|
||||
Although the `./configure` script will generate a `Makefile`, this is actually
|
||||
just a thin veneer over the actual build system driver, `x.py`. This file, at
|
||||
the root of the repository, is used to build, test, and document various parts
|
||||
of the compiler. You can execute it as:
|
||||
|
||||
- `make tips` - show useful targets, variables and other tips for working with
|
||||
the build system.
|
||||
- `make rustc-stage1` - build up to (and including) the first stage. For most
|
||||
cases we don't need to build the stage2 compiler, so we can save time by not
|
||||
building it. The stage1 compiler is a fully functioning compiler and
|
||||
(probably) will be enough to determine if your change works as expected.
|
||||
- `make $host/stage1/bin/rustc` - Where $host is a target triple like x86_64-unknown-linux-gnu.
|
||||
This will build just rustc, without libstd. This is the fastest way to recompile after
|
||||
you changed only rustc source code. Note however that the resulting rustc binary
|
||||
won't have a stdlib to link against by default. You can build libstd once with
|
||||
`make rustc-stage1`, rustc will pick it up afterwards. libstd is only guaranteed to
|
||||
work if recompiled, so if there are any issues recompile it.
|
||||
- `make check` - build the full compiler & run all tests (takes a while). This
|
||||
```sh
|
||||
python x.py build
|
||||
```
|
||||
|
||||
On some systems you can also use the shorter version:
|
||||
|
||||
```sh
|
||||
./x.py build
|
||||
```
|
||||
|
||||
To learn more about the driver and top-level targets, you can execute:
|
||||
|
||||
```sh
|
||||
python x.py --help
|
||||
```
|
||||
|
||||
The general format for the driver script is:
|
||||
|
||||
```sh
|
||||
python x.py <command> [<directory>]
|
||||
```
|
||||
|
||||
Some example commands are `build`, `test`, and `doc`. These will build, test,
|
||||
and document the specified directory. The second argument, `<directory>`, is
|
||||
optional and defaults to working over the entire compiler. If specified,
|
||||
however, only that specific directory will be built. For example:
|
||||
|
||||
```sh
|
||||
# build the entire compiler
|
||||
python x.py build
|
||||
|
||||
# build all documentation
|
||||
python x.py doc
|
||||
|
||||
# run all test suites
|
||||
python x.py test
|
||||
|
||||
# build only the standard library
|
||||
python x.py build src/libstd
|
||||
|
||||
# test only one particular test suite
|
||||
python x.py test src/test/rustdoc
|
||||
|
||||
# build only the stage0 libcore library
|
||||
python x.py build src/libcore --stage 0
|
||||
```
|
||||
|
||||
You can explore the build system throught the various `--help` pages for each
|
||||
subcommand. For example to learn more about a command you can run:
|
||||
|
||||
```
|
||||
python x.py build --help
|
||||
```
|
||||
|
||||
To learn about all possible rules you can execute, run:
|
||||
|
||||
```
|
||||
python x.py build --help --verbose
|
||||
```
|
||||
|
||||
### Useful commands
|
||||
|
||||
Some common invocations of `x.py` are:
|
||||
|
||||
- `x.py build --help` - show the help message and explain the subcommand
|
||||
- `x.py build src/libtest --stage 1` - build up to (and including) the first
|
||||
stage. For most cases we don't need to build the stage2 compiler, so we can
|
||||
save time by not building it. The stage1 compiler is a fully functioning
|
||||
compiler and (probably) will be enough to determine if your change works as
|
||||
expected.
|
||||
- `x.py build src/rustc --stage 1` - This will build just rustc, without libstd.
|
||||
This is the fastest way to recompile after you changed only rustc source code.
|
||||
Note however that the resulting rustc binary won't have a stdlib to link
|
||||
against by default. You can build libstd once with `x.py build src/libstd`,
|
||||
but it is is only guaranteed to work if recompiled, so if there are any issues
|
||||
recompile it.
|
||||
- `x.py test` - build the full compiler & run all tests (takes a while). This
|
||||
is what gets run by the continuous integration system against your pull
|
||||
request. You should run this before submitting to make sure your tests pass
|
||||
& everything builds in the correct manner.
|
||||
- `make check-stage1-std NO_REBUILD=1` - test the standard library without
|
||||
rebuilding the entire compiler
|
||||
- `make check TESTNAME=<substring-of-test-name>` - Run a matching set of tests.
|
||||
- `x.py test src/libstd --stage 1` - test the standard library without
|
||||
recompiling stage 2.
|
||||
- `x.py test src/test/run-pass --filter TESTNAME` - Run a matching set of tests.
|
||||
- `TESTNAME` should be a substring of the tests to match against e.g. it could
|
||||
be the fully qualified test name, or just a part of it.
|
||||
`TESTNAME=collections::hash::map::test_map::test_capacity_not_less_than_len`
|
||||
or `TESTNAME=test_capacity_not_less_than_len`.
|
||||
- `make check-stage1-rpass TESTNAME=<substring-of-test-name>` - Run a single
|
||||
rpass test with the stage1 compiler (this will be quicker than running the
|
||||
command above as we only build the stage1 compiler, not the entire thing).
|
||||
You can also leave off the `-rpass` to run all stage1 test types.
|
||||
- `make check-stage1-coretest` - Run stage1 tests in `libcore`.
|
||||
- `make tidy` - Check that the source code is in compliance with Rust's style
|
||||
guidelines. There is no official document describing Rust's full guidelines
|
||||
as of yet, but basic rules like 4 spaces for indentation and no more than 99
|
||||
characters in a single line should be kept in mind when writing code.
|
||||
- `x.py test src/test/run-pass --stage 1 --filter <substring-of-test-name>` -
|
||||
Run a single rpass test with the stage1 compiler (this will be quicker than
|
||||
running the command above as we only build the stage1 compiler, not the entire
|
||||
thing). You can also leave off the directory argument to run all stage1 test
|
||||
types.
|
||||
- `x.py test src/libcore --stage 1` - Run stage1 tests in `libcore`.
|
||||
- `x.py test src/tools/tidy` - Check that the source code is in compliance with
|
||||
Rust's style guidelines. There is no official document describing Rust's full

#### MSVC with rustbuild

The old build system, based on makefiles, is currently being rewritten into a
|
||||
Rust-based build system called rustbuild. This can be used to bootstrap the
|
||||
compiler on MSVC without needing to install MSYS or MinGW. All you need are
|
||||
[Python 2](https://www.python.org/downloads/),
|
||||
[CMake](https://cmake.org/download/), and
|
||||
[Git](https://git-scm.com/downloads) in your PATH (make sure you do not use the
|
||||
ones from MSYS if you have it installed). You'll also need Visual Studio 2013 or
|
||||
newer with the C++ tools. Then all you need to do is to kick off rustbuild.
|
||||
|
||||
```
|
||||
python x.py build
|

* Adding a new build tool? Take a look at `build/step.rs` for examples of other

adding a new directory with `Cargo.toml` followed by configuring all

`Cargo.toml` files accordingly.
|
||||
* Adding a new dependency from crates.io? We're still working on that, so hold

off on that for now.
|

* Adding a new configuration option? Take a look at `build/config.rs` or perhaps

`build/flags.rs` and then modify the build elsewhere to read that option.

//! This module, and its descendants, are the implementation of the Rust build
|
||||
//! system. Most of this build system is backed by Cargo but the outer layer
|
||||
//! here serves as the ability to orchestrate calling Cargo, sequencing Cargo
|
||||
//! builds, building artifacts like LLVM, etc.
|
||||
//! builds, building artifacts like LLVM, etc. The goals of rustbuild are:
|
||||
//!
|
||||
//! More documentation can be found in each respective module below.
|
||||
//! * To be an easily understandable, easily extensible, and maintainable build
|
||||
//! system.
|
||||
//! * Leverage standard tools in the Rust ecosystem to build the compiler, aka
|
||||
//! crates.io and Cargo.
|
||||
//! * A standard interface to build across all platforms, including MSVC
|
||||
//!
|
||||
//! ## Architecture
|
||||
//!
|
||||
//! Although this build system defers most of the complicated logic to Cargo
|
||||
//! itself, it still needs to maintain a list of targets and dependencies which
|
||||
//! it can itself perform. Rustbuild is made up of a list of rules with
|
||||
//! dependencies amongst them (created in the `step` module) and then knows how
|
||||
//! to execute each in sequence. Each time rustbuild is invoked, it will simply
|
||||
//! iterate through this list of steps and execute each serially in turn. For
|
||||
//! each step rustbuild relies on the step internally being incremental and
|
||||
//! parallel. Note, though, that the `-j` parameter to rustbuild gets forwarded
|
||||
//! to appropriate test harnesses and such.
|
||||
//!
|
||||
//! Most of the "meaty" steps that matter are backed by Cargo, which does indeed
|
||||
//! have its own parallelism and incremental management. Later steps, like
|
||||
//! tests, aren't incremental and simply run the entire suite currently.
|
||||
//!
|
||||
//! When you execute `x.py build`, the steps which are executed are:
|
||||
//!
|
||||
//! * First, the python script is run. This will automatically download the
|
||||
//! stage0 rustc and cargo according to `src/stage0.txt`, or using the cached
|
||||
//! versions if they're available. These are then used to compile rustbuild
|
||||
//! itself (using Cargo). Finally, control is then transferred to rustbuild.
|
||||
//!
|
||||
//! * Rustbuild takes over, performs sanity checks, probes the environment,
|
||||
//! reads configuration, builds up a list of steps, and then starts executing
|
||||
//! them.
|
||||
//!
|
||||
//! * The stage0 libstd is compiled
|
||||
//! * The stage0 libtest is compiled
|
||||
//! * The stage0 librustc is compiled
|
||||
//! * The stage1 compiler is assembled
|
||||
//! * The stage1 libstd, libtest, librustc are compiled
|
||||
//! * The stage2 compiler is assembled
|
||||
//! * The stage2 libstd, libtest, librustc are compiled
|
||||
//!
|
||||
//! Each step is driven by a separate Cargo project and rustbuild orchestrates
|
||||
//! copying files between steps and otherwise preparing for Cargo to run.
|
||||
//!
|
||||
//! ## Further information
|
||||
//!
|
||||
//! More documentation can be found in each respective module below, and you can
|
||||
//! also check out the `src/bootstrap/README.md` file for more information.

// This is the first rule that we're going to define for rustbuild, which is
|
||||
// used to compile LLVM itself. All rules are added through the `rules`
|
||||
// structure created above and are configured through a builder-style
|
||||
// interface.
|
||||
//
|
||||
// First up we see the `build` method. This represents a rule that's part of
|
||||
// the top-level `build` subcommand. For example `./x.py build` is what this
|
||||
// is associating with. Note that this is normally only relevant if you flag
|
||||
// a rule as `default`, which we'll talk about later.
|
||||
//
|
||||
// Next up we'll see two arguments to this method:
|
||||
//
|
||||
// * `llvm` - this is the "human readable" name of this target. This name is
|
||||
// not accessed anywhere outside this file itself (e.g. not in
|
||||
// the CLI nor elsewhere in rustbuild). The purpose of this is to
|
||||
// easily define dependencies between rules. That is, other rules
|
||||
// will depend on this with the name "llvm".
|
||||
// * `src/llvm` - this is the relevant path to the rule that we're working
|
||||
// with. This path is the engine behind how commands like
|
||||
// `./x.py build src/llvm` work. This should typically point
|
||||
// to the relevant component, but if there's not really a
|
||||
// path to be assigned here you can pass something like
|
||||
// `path/to/nowhere` to ignore it.
|
||||
//
|
||||
// After we create the rule with the `build` method we can then configure
|
||||
// various aspects of it. For example this LLVM rule uses `.host(true)` to
|
||||
// flag that it's a rule only for host targets. In other words, LLVM isn't
|
||||
// compiled for targets configured through `--target` (e.g. those we're just
|
||||
// building a standard library for).
|
||||
//
|
||||
// Next up the `dep` method will add a dependency to this rule. The closure
|
||||
// is yielded the step that represents executing the `llvm` rule itself
|
||||
// (containing information like stage, host, target, ...) and then it must
|
||||
// return a target that the step depends on. Here LLVM is actually
|
||||
// interesting where a cross-compiled LLVM depends on the host LLVM, but
|
||||
// otherwise it has no dependencies.
|
||||
//
|
||||
// To handle this we do a bit of dynamic dispatch to see what the dependency
|
||||
// is. If we're building a LLVM for the build triple, then we don't actually
|
||||
// have any dependencies! To do that we return a dependency on the "dummy"
|
||||
// target which does nothing.
|
||||
//
|
||||
// If we're build a cross-compiled LLVM, however, we need to assemble the
|
||||
// libraries from the previous compiler. This step has the same name as
|
||||
// ours (llvm) but we want it for a different target, so we use the
|
||||
// builder-style methods on `Step` to configure this target to the build
|
||||
// triple.
|
||||
//
|
||||
// Finally, to finish off this rule, we define how to actually execute it.
|
||||
// That logic is all defined in the `native` module so we just delegate to
|
||||
// the relevant function there. The argument to the closure passed to `run`
|
||||
// is a `Step` (defined below) which encapsulates information like the

// stage, target, host, etc.
