Cargo lock tidy check
A rebased PR for #32901
|
|
|
|

This commit adds support to rustbuild to run all documentation tests, basically
running `rustdoc --test` over all our documentation. This also includes support
for running the error index tests.

Bring the calculation logic in line with the makefiles and also set the
RUSTC_BOOTSTRAP_KEY environment variable to enable the bootstrap on the stable
compiler.

rustbuild: Fix compile on OSX for 10.7
This commit should help configure our OSX rustbuild builder for targeting 10.7.
A key part of this is using `libc++` instead of `libstdc++` as apparently it's
more filled out and otherwise LLVM's cmake configuration would fail.

The `rust-std` package that we produce is expected to have not only the standard
library but also libtest for compiling unit tests. Unfortunately this does not
currently happen due to the way rustbuild is structured.
There are currently two main stages of compilation in rustbuild, one for the
standard library and one for the compiler. This is primarily done to allow us to
fill in the sysroot right after the standard library has finished compiling to
continue compiling the rest of the crates. Consequently the entire compiler does
not have to explicitly depend on the standard library, and this also should
allow us to pull in crates.io dependencies into the build in the future because
they'll just naturally build against the std we just produced.
These phases, however, do not represent a cross-compiled build. Target-only
builds also require libtest, and libtest is currently part of the
all-encompassing "compiler build". There's unfortunately no way to learn about
just libtest and its dependencies (in a great and robust fashion) so to ensure
that we can copy the right artifacts over this commit introduces a new build
step, libtest.
The new libtest build step has documentation, dist, and link steps as std/rustc
already do. The compiler now depends on libtest instead of libstd, and all
compiler crates can now assume that test and its dependencies are implicitly
part of the sysroot (hence explicit dependencies being removed). This makes the
build a tad less parallel as in theory many rustc crates can be compiled in
parallel with libtest, but this likely isn't where we really need parallelism
either (all the time is still spent in the compiler).
All in all this allows the `dist-std` step to depend on both libstd and libtest,
so `rust-std` packages produced by rustbuild should start having both the
standard library and libtest.
Closes #32523

This commit implements the `make dist` command in the new rustbuild build
system, porting over `dist.mk` and `prepare.mk` into Rust. There's a huge amount
of complexity between those two files, not all of which is likely justified, so
the Rust implementation is *much* smaller.
Currently the implementation still shells out to rust-installer as well as some
python scripts, but ideally we'd rewrite it all in the future to not shell out
and be in Rust proper.

The facet of a stage is rarely relevant when running a tool or building
something, it's all a question of what stage the *compiler* is built in. We've
already got a nice handy `Compiler` structure to carry this information, so
let's use it!
This refactors the signature of the `Build::cargo` function two ways:
1. The `stage` argument is removed, this was just duplicated with the `compiler`
argument's stage field.
2. The `target` argument is now required. This was a bug where if the `--target`
flag isn't passed then the snapshot stage0 compiler is always used, so we
won't pick up any changes.
Much of the other changes in this commit are just propagating these decisions
outwards. For example many of the `Step` variants no longer have a stage
argument as they're baked into the compiler.

We've actually got quite a few tools that are compiled as part of our build,
let's start housing them all in a `tools` directory.
|
|
The standard library doesn't depend on rustc_bitflags, so move it to explicit
dependencies on all other crates. Additionally, the arena/fmt_macros deps could
be dropped from libsyntax.
|
|
These describe the structure of all our crate dependencies.

This commit is the start of a series of commits which start to replace the
makefiles with a Cargo-based build system. The aim is not to remove the
makefiles entirely just yet but rather just replace the portions that invoke the
compiler to do the bootstrap. This commit specifically adds enough support to
perform the bootstrap (and all the cross compilation within) along with
generating documentation.
More commits will follow up in this series to actually wire up the makefiles to
call this build system, so stay tuned!
