Now that we've fully moved to Azure Pipelines and bors has been updated
to only gate on Azure this commit removes the remaining Travis/AppVeyor
support contained in this repository. Most of the deletions here are
related to producing better output on Travis by folding certain
sections. This isn't supported by Azure so there's no need to keep it
around, and if Azure ever adds support we can always add it back!

This commit disables all builders on Travis and almost all builders on
AppVeyor now that they're all running on Azure Pipelines. There is one
remaining builder on AppVeyor which hasn't been migrated yet due to a
test failure on Azure, which we'll be debugging soon. One remaining
builder is left on Travis which is the tools builder whenever a
submodule is changed, but we'll probably turn that off soon since it's
just for PRs.
The other major change in this PR is that the auto builders on Azure are
now configured with "real" prod credentials which should cause them to
publish all artifacts into the official CI buckets.
|
|
Ensure that they're all forwards-compatible with AWS updates happening
next year by ensuring the bucket name shows up in the domain name.
Closes #61168

Ship profiler with windows-gnu
Fixes https://github.com/rust-lang/rust/issues/49409
I don't know if we can enable it for testing, windows-gnu jobs are already taking too long: https://github.com/rust-lang/rust/issues/59637.
r? @michaelwoerister
P.S.
I have tested only x86_64 build.

Tracked at #59637 for re-enabling this commit disables assertions to
hopefully bring the runtime for this builder under control.

This should make it easier to identify what each job is doing when looking at the Travis or Appveyor UI.
- Set `name` for each job in Travis.
- Move `CI_JOB_NAME` to the front in Appveyor so that it appears first in the UI.

appveyor: Use VS2017 for all our images
Originally added in #55935 to test build times, this was reverted
in #56201 due to a belief that it caused the exit code 259 spurious
errors. We've since learned, however, that the 259 exit code is likely
not related to this image update as we're getting it in a number of
locations now.
VS2017 looks like it may be required to compile LLVm in the near future,
notably discovered by #58408 where we attempted to update LLVM.

appveyor: Use VS2017 for all our images
This was [recommended by AppVeyor][1] to see if it has any impact on our
build times, hopefully on the beneficial side of things! This shouldn't
affect our binary compatibility for generated compilers like it would
normally do for Linux.

[Recommended by AppVeyor][1] this isn't done by default for all builds
due to the high startup overhead (3-4 minutes for a VM), but that's
paltry compared to our overall build times so should be more than
applicable!

add an appveyor config for aarch64-pc-windows-msvc
This is purely a cargo-cult of things to solicit feedback from humans and/or automation failures. Not sure that the build artifacts would get packaged properly to start providing nightly tarballs for `libstd`, but this is at least a start.
Fixes #53864.

This version ought to work better with MSVC 15.9 preview headers.

This commit moves a number of our encrypted credentials stored in
configuration files in this repository to env vars on the web UI. This
will hopefully make it easier to rotate credentials in the future as
well as quickly change them if the need arises. (quicker than landing a
PR that is).
This also updates the travis deployment process to always use the `aws`
command line tool which we're already installing on Linux and should
enable us to avoid all `dpl` gem issues as well as have greater control
over what's going where.

Currently on CI we predominately compile LLVM with the default system compiler
which means gcc on Linux, some version of Clang on OSX, MSVC on Windows, and
gcc on MinGW. This commit switches Linux, OSX, and Windows to all use Clang
6.0.0 to build LLVM (aka the C/C++ compiler as part of the bootstrap). This
looks to generate faster code according to #49879 which translates to a faster
rustc (as LLVM internally is faster)
The major changes here were to the containers that build Linux releases,
basically adding a new step that uses the previous gcc 4.8 compiler to compile
the next Clang 6.0.0 compiler. Otherwise the OSX and Windows scripts have been
updated to download precompiled versions of Clang 6 and configure the build to
use them.
Note that `cc` was updated here to fix using `clang-cl` with `cc-rs` on MSVC, as
well as an update to `sccache` on Windows which was needed to correctly work
with `clang-cl`. Finally the MinGW compiler is entirely left out here
intentionally as it's currently thought that Clang can't generate C++ code for
MinGW and we need to use gcc, but this should be verified eventually.
|
|
Bots that read the log can simply look for `[CI_JOB_NAME=...]` to find out
the job's name.
|
|
Ideally I'd like to soon enable sccache for rustbuild itself and some of the
stage0 tools, but for that to work we'll need some better Rust support than the
pretty old version we were previously using!

We've made headway towards splitting the test suite across two appveyor builders
and this moves one more tests suite between builders. The last [failed
build][fail] had its longest running test suite and I've moved that to the
secondary builder.

Take two more slow builders and split them in two to get them under 2 hrs

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.

Run-pass and compile-fail tests appear to take the most significant
chunk of time, so split them into their own builder.

This commit introduces a separately compiled backend for Emscripten, avoiding
compiling the `JSBackend` target in the main LLVM codegen backend. This builds
on the foundation provided by #47671 to create a new codegen backend dedicated
solely to Emscripten, removing the `JSBackend` of the main codegen backend in
the process.
A new field was added to each target for this commit which specifies the backend
to use for translation, the default being `llvm` which is the main backend that
we use. The Emscripten targets specify an `emscripten` backend instead of the
main `llvm` one.
There's a whole bunch of consequences of this change, but I'll try to enumerate
them here:
* A *second* LLVM submodule was added in this commit. The main LLVM submodule
will soon start to drift from the Emscripten submodule, but currently they're
both at the same revision.
* Logic was added to rustbuild to *not* build the Emscripten backend by default.
This is gated behind a `--enable-emscripten` flag to the configure script. By
default users should neither check out the emscripten submodule nor compile
it.
* The `init_repo.sh` script was updated to fetch the Emscripten submodule from
GitHub the same way we do the main LLVM submodule (a tarball fetch).
* The Emscripten backend, turned off by default, is still turned on for a number
of targets on CI. We'll only be shipping an Emscripten backend with Tier 1
platforms, though. All cross-compiled platforms will not be receiving an
Emscripten backend yet.
This commit means that when you download the `rustc` package in Rustup for Tier
1 platforms you'll be receiving two trans backends, one for Emscripten and one
that's the general LLVM backend. If you never compile for Emscripten you'll
never use the Emscripten backend, so we may update this one day to only download
the Emscripten backend when you add the Emscripten target. For now though it's
just an extra 10MB gzip'd.
Closes #46819

If a PR intends to update a tool but its test has failed, abort the merge
regardless of current channel. This should help the tool maintainers if the
update turns out to be failing due to changes in latest master.

ci: Upload/download from a new S3 bucket
Moving buckets from us-east-1 to us-west-1 because us-west-1 is where
rust-central-station itself runs and in general is where we have all our other

|

Most of the other rust-lang buckets are in us-west-1 and I think the original
bucket was just accidentally created in the us-east-1 region. Let's consolidate
by moving it to the same location as the rest of our buckets.

Haven't done this in awhile so seems like a good idea!

Chocolatey has been pretty flaky, so let's not rely on it.

Fixes #43881. Reduces AppVeyor test time back to ~2 hours on
average.
The i586 libstd was never tested before Aug 13th, so this PR
brings the situation back to the previous status-quo.
