The current plan is that submodule tracks the `release` branch of
rust-analyzer, which is updated once a week.
rust-analyzer is a workspace (with a virtual manifest), the actual
binary is provide by `crates/rust-analyzer` package.
Note that we intentionally don't add rust-analyzer to `Kind::Test`,
for two reasons.
*First*, at the moment rust-analyzer's test suite does a couple of
things which might not work in the context of rust repository. For
example, it shells out directly to `rustup` and `rustfmt`. So, making
this work requires non-trivial efforts.
*Second*, it seems unlikely that running tests in rust-lang/rust repo
would provide any additional guarantees. rust-analyzer builds with
stable and does not depend on the specifics of the compiler, so
changes to compiler can't break ra, unless they break stability
guarantee. Additionally, rust-analyzer itself is gated on bors, so we
are pretty confident that test suite passes.

This commit fixes a regression introduced in #73317 where an oversight
meant that `config.toml` was assumed to exist.

This commit modifies bootstrap so that `config.toml` is read first from
`RUST_BOOTSTRAP_CONFIG`, then `--config` and finally `config.toml` in the
current directory.
This is a subjective change, intended to improve the ergnomics when
using "development shells" for rustc development (for example, using tools
such as Nix) which set environment variables to ensure a reproducible
environment (these development shells can then be version controlled). By
optionally reading `config.toml` from an environment variable, a `config.toml`
can be defined in the development shell and a path to it exposed in the
`RUST_BOOTSTRAP_CONFIG` environment variable - avoiding the need to manually
symlink the contents of this file to `config.toml` in the working
directory.

This allows configuring the directory for build artifacts, instead of having it always be ./build. This means you can set it to a constant location, letting you reuse the same cache while working in several different directories.
The configuration lives in config.toml under build.build-dir. By default, it keeps the existing default of ./build, but it can be configured to any relative or absolute path. Additionally, it allows making outputs relative to the root of the git repository using $ROOT.

This also abstracts checking for a command into `require`.

Otherwise each update is run twice and errors are printed

With #65251 landed there's no need to build two LLVM backends and ship
them with rustc, every target we have now uses the same LLVM backend!
This removes the `src/llvm-emscripten` submodule and additionally
removes all support from rustbuild for building the emscripten LLVM
backend. Multiple codegen backend support is left in place for now, and
this is intended to be an easy 10-15 minute win on CI times by avoiding
having to build LLVM twice.

Ensure edition lints and internal lints are enabled with deny-warnings=false
Previously we only passed the deny command line flags if deny-warnings was enabled, but now we either pass -W... or -D... for each of the flags as appropriate.
This is also a breaking change to x.py as it changes `--warnings=allow` to `--warnings=warn` which is what that flag actually did; we don't have an allow warnings mode.

bootstrap: allow specifying mirror for bootstrap compiler download.
|
|
|
|
When deny-warnings is not specified or set to true, the behaviour is the same as before.
When deny-warnings is set to false, warnings are now allowed

The new git submodule src/llvm-project is a monorepo replacing src/llvm
and src/tools/{clang,lld,lldb}. This also serves as a rebase for these
projects to the new 8.x branch from trunk.
The src/llvm-emscripten fork is unchanged for now.

./x.py used to automatically check out the right commit when a submodule was outdated and ./x.py build was run
and submodules handling was enabled in config.toml (submodules = true).
But it threw an error:
[...]
failed to run: git submodule -q sync --progress src/tools/clippy
The commit removes the --progress from git submodule call.
Fixes #57080

This commit removes all jemalloc related submodules, configuration, etc,
from the bootstrap, from the standard library, and from the compiler.
This will be followed up with a change to use jemalloc specifically as
part of rustc on blessed platforms.

This optionally adds lldb (and clang, which it needs) to the build.
Because rust uses LLVM 7, and because clang 7 is not yet released, a
recent git master version of clang is used.
The lldb that is used includes the Rust plugin.
lldb is only built when asked for, or when doing a nightly build on
macOS. Only macOS is done for now due to difficulties with the Python
dependency.

If you are using a hard-linked file as your config.toml, this change will affect the way other instances of the file is modified.
The original version would modify all other instances whereas the new version will leave others unchanged, reducing the ref count by one.

Tests should always use "rustc" and "cargo" from config.toml instead
of assuming that stage0 binaries was downloaded to build directory.
