Previously, we were emittinng analysis data for all tasks, including `doc`. That meant we got two sets of save-analysis data, one from the normal build and one from the docs. That means indexing with the RLS took twice as long and made downloads larger and build times longer.

Add warning if a resolution failed
r? @QuietMisdreavus

Debugging information for the extended tools is currently disabled for
concerns about the size. This patch adds `--enable-debuginfo-tools` to
let one opt into having that debuginfo.
This is useful for debugging the tools in distro packages. We always
strip debuginfo into separate packages anyway, so the extra size is not
a concern in regular use.

This permits easier iteration without having to worry about warnings
being denied.

This ensures that each build will support the testing design of "dry
running" builds. It's also checked that a dry run build is equivalent
step-wise to a "wet" run build; the graphs we generate when running are
directly compared node/node and edge/edge, both for order and contents.

In order to run tests, previous commits have cfg'd out various parts of
rustbuild. Generally speaking, these are filesystem-related operations
and process-spawning related parts. Then, rustbuild is run "as normal"
and the various steps that where run are retrieved from the cache and
checked against the expected results.
Note that this means that the current implementation primarily tests
"what" we build, but doesn't actually test that what we build *will*
build. In other words, it doesn't do any form of dependency verification
for any crate. This is possible to implement, but is considered future
work.
This implementation strives to cfg out as little code as possible; it
also does not currently test anywhere near all of rustbuild. The current
tests are also not checked for "correctness," rather, they simply
represent what we do as of this commit, which may be wrong.
Test cases are drawn from the old implementation of rustbuild, though
the expected results may vary.

When the RUSTFLAGS_STAGE_{1,2} is not set, including a space means
the string will always be non-empty and RUSTFLAGS will be always be
reset which breaks other ways of setting these such as through config
in CARGO_HOME.

Host compiler documentation
Fixes #29893. Rust Central Station PR: rust-lang/rust-central-station#40
r? @alexcrichton

This commit is an implementation of adding custom sections to wasm artifacts in
rustc. The intention here is to expose the ability of the wasm binary format to
contain custom sections with arbitrary user-defined data. Currently neither our
version of LLVM nor LLD supports this so the implementation is currently custom
to rustc itself.
The implementation here is to attach a `#[wasm_custom_section = "foo"]`
attribute to any `const` which has a type like `[u8; N]`. Other types of
constants aren't supported yet but may be added one day! This should hopefully
be enough to get off the ground with *some* custom section support.
The current semantics are that any constant tagged with `#[wasm_custom_section]`
section will be *appended* to the corresponding section in the final output wasm
artifact (and this affects dependencies linked in as well, not just the final
crate). This means that whatever is interpreting the contents must be able to
interpret binary-concatenated sections (or each constant needs to be in its own
custom section).
To test this change the existing `run-make` test suite was moved to a
`run-make-fulldeps` folder and a new `run-make` test suite was added which
applies to all targets by default. This test suite currently only has one test
which only runs for the wasm target (using a node.js script to use `WebAssembly`
in JS to parse the wasm output).

This commit updates CI configuration to inform rustbuild that it should print
out how long each step takes on CI. This'll hopefully allow us to track the
duration of steps over time and follow regressions a bit more closesly (as well
as have closer analysis of differences between two builds).

Support extra-verbose builds
- The bootstrap crate currently passes -v to Cargo if itself invoked with -vv. But Cargo supports -vv (to show build script output), so make bootstrap pass that if itself invoked with -vvv. (More specifically, pass N '-v's to Cargo if invoked with N+1 of them.)
- bootstrap.py currently tries to pass on up to two '-v's to cargo when building bootstrap, but incorrectly ('-v' is marked as 'store_true', so argparse stores either False or True, ignoring multiple '-v's). Fix this, allow passing any number of '-v's, and make it consistent with bootstrap's invocation of Cargo (i.e. subtract one from the number of '-v's).
- Also improve bootstrap.py's config.toml 'parsing' to support arbitrary verbosity levels, + allow command line to override it.

rustbuild: Remove ThinLTO-related configuration
This commit removes some ThinLTO/codegen unit cruft primarily only needed during
the initial phase where we were adding ThinLTO support to rustc itself. The
current bootstrap compiler knows about ThinLTO and has it enabled by default for
multi-CGU builds which are also enabled by default. One CGU builds (aka
disabling ThinLTO) can be achieved by configuring the number of codegen units to
1 for a particular builds.
This also changes the defaults for our dist builders to go back to multiple
CGUs. Unfortunately we're seriously bleeding for cycle time on the bots right
now so we need to recover any time we can.

Update Cargo submodule
Hopefully a routine update...
|
|
Required moving all fulldeps tests depending on `rand` to different locations as
now there's multiple `rand` crates that can't be implicitly linked against.

Previously it was set to true when we didn't run HOSTS steps.
|
|
All uses are replaced with not accessing run.target/run.host, and
instead directly using run.builder.build.build.
|
|
All cases where it is used can be replaced by substituing run.host for
run.builder.build.build; that is its only effect. As such, it is
removable.

rustbuild: Pass `ccache` to build scripts
This is a re-attempt at #48192 hopefully this time with 100% less randomly
[blocking builds for 20 minutes][block]. To work around #48192 the sccache
server is started in the `run.sh` script very early on in the compilation
process.

This commit imports the LLD project from LLVM to serve as the default linker for
the `wasm32-unknown-unknown` target. The `binaryen` submoule is consequently
removed along with "binaryen linker" support in rustc.
Moving to LLD brings with it a number of benefits for wasm code:
* LLD is itself an actual linker, so there's no need to compile all wasm code
with LTO any more. As a result builds should be *much* speedier as LTO is no
longer forcibly enabled for all builds of the wasm target.
* LLD is quickly becoming an "official solution" for linking wasm code together.
This, I believe at least, is intended to be the main supported linker for
native code and wasm moving forward. Picking up support early on should help
ensure that we can help LLD identify bugs and otherwise prove that it works
great for all our use cases!
* Improvements to the wasm toolchain are currently primarily focused around LLVM
and LLD (from what I can tell at least), so it's in general much better to be
on this bandwagon for bugfixes and new features.
* Historical "hacks" like `wasm-gc` will soon no longer be necessary, LLD
will [natively implement][gc] `--gc-sections` (better than `wasm-gc`!) which
means a postprocessor is no longer needed to show off Rust's "small wasm
binary size".
LLD is added in a pretty standard way to rustc right now. A new rustbuild target
was defined for building LLD, and this is executed when a compiler's sysroot is
being assembled. LLD is compiled against the LLVM that we've got in tree, which
means we're currently on the `release_60` branch, but this may get upgraded in
the near future!
LLD is placed into rustc's sysroot in a `bin` directory. This is similar to
where `gcc.exe` can be found on Windows. This directory is automatically added
to `PATH` whenever rustc executes the linker, allowing us to define a `WasmLd`
linker which implements the interface that `wasm-ld`, LLD's frontend, expects.
Like Emscripten the LLD target is currently only enabled for Tier 1 platforms,
notably OSX/Windows/Linux, and will need to be installed manually for compiling
to wasm on other platforms. LLD is by default turned off in rustbuild, and
requires a `config.toml` option to be enabled to turn it on.
Finally the unstable `#![wasm_import_memory]` attribute was also removed as LLD
has a native option for controlling this.

Auto-toolstate management follow-up.
Tracking comment: https://github.com/rust-lang/rust/issues/45861#issuecomment-367302777
* Fixed rust-lang-nursery/rust-toolstate#1, a proper link to the PR will be included.
* Fixed rust-lang-nursery/rust-toolstate#2, a comment will be posted to the PR if the toolstate changed
* Toolstate regression will be rejected at the last week of the 6-week cycle (currently entirely date-based).
* Implemented https://internals.rust-lang.org/t/the-current-submodule-setup-is-not-tenable/6593, moved doc tests of Nomicon, Reference, Rust-by-Example and The Book to the "tools" job and thus allowed to fail like other external tools.

Added error-format flag to x.py.
Fixes #48475

The *.md at the root directory in src/doc are no longer tested, but this
should be fine since all files there are deprecated.
|

This re-introduces a `Config.libdir_relative` field, now derived from
`libdir` and made relative to `prefix` if necessary.
This fixes a regression from #46592 when `--libdir` is given an absolute
path. `Builder::sysroot_libdir` should always use a relative path so
its callers don't clobber system locations, and `librustc` also asserts
that `CFG_LIBDIR_RELATIVE` is really relative.
|
|
|
|
We'd previously assumed that these paths would be relative to the src
dir, and that for example our various CI scripts would, when calling
x.py, use `../x.py build ../src/tools/...` but this isn't the case --
they use `../x.py` without using the relevant source-relative path.
We eventually may want to make this (actually somewhat logical) change,
but this is not that time.
|
|
Primarily for CI purposes; this is intended to avoid cases where we
update rustbuild and unintentionally make CI stop running some builds to
the arguments being passed no longer applying for some reason.

Implement excluding a build-step via --exclude
First step to fixing https://github.com/rust-lang/rust/issues/47911. This doesn't change any CI configuration, but implements what I believe necessary to make that feasible in rustbuild.
In theory this should be sufficient to allow someone to open a PR against .travis.yml and appveyor.yml which splits the Windows 32-bit tests and maybe the OS X tests into multiple builders (depending on what our cost-concerns are) to reduce runtimes.

This reverts commit 64a8730e171367e4979cd9c25f0e0fdc2c157446.
|
|
Some Steps are by-default run but don't have any paths associated with
them. We need to have at least one PathSet per each Step, though, so we
add an empty one on calls to `never()`.
|
|
Previously, a Step would be able to tell on its own when it was invoked
"by-default" (that is, `./x.py test` was called instead of `./x.py test
some/path`). This commit replaces that functionality, invoking each Step
with each of the paths it has specified as "should be invoked by."
For example, if a step calls `path("src/tools/cargo")` and
`path("src/doc/cargo")` then it's make_run will be called twice, with
"src/tools/cargo" and "src/doc/cargo." This makes it so that default
handling logic is in builder, instead of spread across various Steps.
However, this meant that some Step specifications needed to be updated,
since for example `rustdoc` can be built by `./x.py build
src/librustdoc` or `./x.py build src/tools/rustdoc`. A `PathSet`
abstraction is added that handles this: now, each Step can not only list
`path(...)` but also `paths(&[a, b, ...])` which will make it so that we
don't invoke it with each of the individual paths, instead invoking it
with the first path in the list (though this shouldn't be depended on).
Future work likely consists of implementing a better/easier way for a
given Step to work with "any" crate in-tree, especially those that want
to run tests, build, or check crates in the std, test, or rustc crate
trees. Currently this is rather painful to do as most of the logic is
duplicated across should_run and make_run. It seems likely this can be
abstracted away into builder somehow.
