travis: Ensure cargo links libcurl statically
We don't want a dynamic dependency in the library that we ship, so link it
statically by configuring curl-sys's build script to not pick up the system
version via pkg-config.
rustbuild: Make save-analysis an option
This makes save-analysis an option independent from the release channel.
The CI build scripts have been modified to enable the flag.
*Merge with caution.* I haven't tested this, and this can cause nightly breakage.

rustbuild: Build documentation for `proc_macro`
This commit fixes#38749 by building documentation for the `proc_macro` crate by
default for configured hosts. Unfortunately did not turn out to be a trivial
fix. Currently rustbuild generates documentation into multiple locations: one
for std, one for test, and one for rustc. The initial fix for this issue simply
actually executed `cargo doc -p proc_macro` which was otherwise completely
elided before.
Unfortunately rustbuild was the left to merge two documentation trees together.
One for the standard library and one for the rustc tree (which only had docs for
the `proc_macro` crate). Rustdoc itself knows how to merge documentation files
(specifically around search indexes, etc) but rustbuild was unaware of this, so
an initial fix ended up destroying the sidebar and the search bar from the
libstd docs.
To solve this issue the method of documentation has been tweaked slightly in
rustbuild. The build system will not use symlinks (or directory junctions on
Windows) to generate all documentation into the same location initially. This'll
rely on rustdoc's logic to weave together all the output and ensure that it ends
up all consistent.
Closes#38749
travis: Attempt to debug sccache failures
I can't find anything that'd cause unexpected EOF in the source, so let's try
taking a look at the error logs on failures.

This change introduces a Dockerfile and script which builds a complete
Fuchsia toolchain which can be used to build Rust distribution for
Fuchsia. We only support cross-compiling at the moment, hence only
setting the target.
Travis only gives us 30GB disk space and we don't currently have an option to
increase that. Each musl target generates "hello world" binaries of about 3.5MB
in size, and we're testing two targets in the same image. We have around 3k
run-pass tests and 2 musl targets which works out to around 20GB. That's
dangerously close to the limit and is causing PRs to bounce.
This PR splits up the builder in two, one for x86_64 musl and the other for
i686. Hopefully that'll keep us under the disk limit.
Closes#40359
This commit adds support to rustbuild for compiling Cargo as part of the release
process. Previously rustbuild would simply download a Cargo snapshot and
repackage it. With this change we should be able to turn off artifacts from the
rust-lang/cargo repository and purely rely on the artifacts Cargo produces here.
The infrastructure added here is intended to be extensible to other components,
such as the RLS. It won't exactly be a one-line addition, but the addition of
Cargo didn't require too much hooplah anyway.
The process for release Cargo will now look like:
* The rust-lang/rust repository has a Cargo submodule which is used to build a
Cargo to pair with the rust-lang/rust release
* Periodically we'll update the cargo submodule as necessary on rust-lang/rust's
master branch
* When branching beta we'll create a new branch of Cargo (as we do today), and
the first commit to the beta branch will be to update the Cargo submodule to
this exact revision.
* When branching stable, we'll ensure that the Cargo submodule is updated and
then make a stable release.
Backports to Cargo will look like:
* Send a PR to cargo's master branch
* Send a PR to cargo's release branch (e.g. rust-1.16.0)
* Send a PR to rust-lang/rust's beta branch updating the submodule
* Eventually send a PR to rust-lang/rust's master branch updating the submodule
For reference, the process to add a new component to the rust-lang/rust release
would look like:
* Add `$foo` as a submodule in `src/tools`
* Add a `tool-$foo` step which compiles `$foo` with the specified compiler,
likely mirroring what Cargo does.
* Add a `dist-$foo` step which uses `src/tools/$foo` and the `tool-$foo` output
to create a rust-installer package for `$foo` likely mirroring what Cargo
does.
* Update the `dist-extended` step with a new dependency on `dist-$foo`
* Update `src/tools/build-manifest` for the new component.
PRs can't land againt beta right now because the android bot is filling up on
disk space. I don't really know what's going on but the android bot is the
longest one to run anyway so it'll benefit from being split up regardless.
Now that mozilla/sccache#43 is fixed the caching works for MinGW on Windows. We
still can't use it for MSVC just yet, but I'll try to revive that branch at some
point.
This commit attempts to move more network operations to being retryable through
various operations. For example git submodule updates, downloading snapshots,
etc, are now all in retryable steps.
Hopefully this commit can cut down on the number of network failures we've been
seeing!
travis: Compile a more compatible libc.a for musl
The mitigations for #34978 involve passing `-Wa,-mrelax-relocations=no` to all C
code we compile, and we just forgot to pass it when compiling musl itself.
Closes#39979
Currently CI builds can fail spuriously during the LLVM build (#39003). I
believe this is due to sccache, and I believe that in turn was due to the fact
that the sccache server used to just be a raw mio server. Historically raw mio
servers are quite complicated to get right, but this is why we built Tokio! The
sccache server has been migrated to Tokio which I suspect would fix any latent
issues.
I have no confirmation of this (never been able to reproduce the deadlock
locally), but my hunch is that updating sccache to the master branch will fix
the timeouts during the LLVM build.
The binaries previously came from Gecko's infrastructure, but I've built new
ones by hand for Win/Mac/Linux and uploaded them to our CI bucket.

travis: Disable source tarballs on most builders
Currently we create a source tarball on almost all of the `DEPLOY=1` builders
but this has the adverse side effect of all source tarballs overriding
themselves in the S3 bucket. Normally this is ok but unfortunately a source
tarball created on Windows is not buildable on Unix.
On Windows the vendored sources contain paths with `\` characters in them which
when interpreted on Unix end up in "file not found" errors.
Instead of this overwriting behavior, whitelist just one linux builder for
producing tarballs and avoid producing tarballs on all other hosts.

travis: Add builders without assertions
This commit adds three new builders, one OSX, one Linux, and one MSVC, which
will produce "nightlies" with LLVM assertions disabled. Currently all nightly
releases have LLVM assertions enabled to catch bugs before they reach the
beta/stable channels. The beta/stable channels, however, do not have LLVM
assertions enabled.
Unfortunately though projects like Servo are stuck on nightlies for the near
future at least and are also suffering very long compile times. The purpose of
this commit is to provide artifacts to these projects which are not distributed
through normal channels (e.g. rustup) but are provided for developers to use
locally if need be.
Logistically these builds will all be uploaded to `rustc-builds-alt` instead of
the `rustc-builds` folder of the `rust-lang-ci` bucket. These builds will stay
there forever (until cleaned out if necessary) and there are no plans to
integrate this with rustup and/or the official release process.

travis: Fix build order of dist-x86-linux
I just tried to build this container locally but it looks like connecting to
ftp.gnu.org requires SNI, so let's build curl/OpenSSL first to ensure that we've
got an SNI-capable client to download gcc/binutils with.

Delete the makefile build system
This PR deletes the makefile build system in favor of the rustbuild build system. The beta has now been branched so 1.16 will continue to be buildable from the makefiles, but going forward 1.17 will only be buildable with rustbuild.
Rustbuild has been the default build system [since 1.15.0](https://github.com/rust-lang/rust/pull/37817) and the makefiles were [proposed for deletion](https://internals.rust-lang.org/t/proposal-for-promoting-rustbuild-to-official-status/4368) at this time back in November of last year.
And now with the deletion of these makefiles we can start getting those sweet sweet improvements of using crates.io crates in the compiler!
Add support for test suites emulated in QEMU
This commit adds support to the build system to execute test suites that cannot
run natively but can instead run inside of a QEMU emulator. A proof-of-concept
builder was added for the `arm-unknown-linux-gnueabihf` target to show off how
this might work.
In general the architecture is to have a server running inside of the emulator
which a local client connects to. The protocol between the server/client
supports compiling tests on the host and running them on the target inside the
emulator.

travis: Gate on some minimal support for incremental compilation.
This commit adds a travis job that
1. builds a stage2 compiler in incremental mode (but with empty incremental compilation cache), and
2. builds and runs the run-pass test suite also in incremental mode.
Building incrementally with an empty cache makes sure that the compiler doesn't crash in dependency tracking during bootstrapping. Executing the incrementally built test suite gives some measure of confidence that we generate valid code.
Note, however, that the above does not give strong guarantees about the validity of incremental compilation, it just provides a basis for being able to rely on from-scratch incr. comp. builds as reference values in further tests (which then do actual incremental compilation).

Using Ubuntu's cross-toolchains for powerpc* and s390x meant they were
depending on glibc symbols from Ubuntu 16.04. And if that host is ever
updated to a new release, the toolchains would raise the bar too.
This switches powerpc, powerpc64, and s390x to use crosstool-ng
toolchains, configured approximately like RHEL6 with kernel 2.6.32 and
glibc 2.12. This ABI level should also be compatible with Debian 7
(wheezy) and Ubuntu 12.04 (precise).
For powerpc64le, the challenge was that only glibc-2.19 officially added
support, but RHEL7 backported those changes to glibc-2.17. The backport
patches are complex and numerous, so instead of trying to push those
into crosstool-ng, this just uses glibc binaries directly from CentOS 7
and builds the toolchain manually.
This is ported from rust-lang/rust-buildbot#149.

rustbuild: Start building --enable-extended
This commit adds a new flag to the configure script,
`--enable-extended`, which is intended for specifying a desire to
compile the full suite of Rust tools such as Cargo, the RLS, etc. This
is also an indication that the build system should create combined
installers such as the pkg/exe/msi artifacts.
Currently the `--enable-extended` flag just indicates that combined
installers should be built, and Cargo is itself not compiled just yet
but rather only downloaded from its location. The intention here is to
quickly get to feature parity with the current release process and then
we can start improving it afterwards.
All new files in this PR inside `src/etc/installer` are copied from the
rust-packaging repository.
