-The goal of the libc crate is to have CI running everywhere to have the
-strongest guarantees about the definitions that this library contains, and as a
-result the CI is pretty complicated and also pretty large! Hopefully this can
-serve as a guide through the sea of scripts in this directory and elsewhere in
-this project.
-
-# Files
-
-First up, let's talk about the files in this directory:
-
-* `run-travis.sh` - a shell script run by all Travis builders, this is
-  responsible for setting up the rest of the environment such as installing new
-  packages, downloading Rust target libraries, etc.
-
-* `run.sh` - the actual script which runs tests for a particular architecture.
-  Called from the `run-travis.sh` script this will run all tests for the target
-  specified.
-
-* `cargo-config` - Cargo configuration of linkers to use copied into place by
-  the `run-travis.sh` script before builds are run.
-
-* `dox.sh` - script called from `run-travis.sh` on only the linux 64-bit nightly
-  Travis bots to build documentation for this crate.
-
-* `landing-page-*.html` - used by `dox.sh` to generate a landing page for all
-  architectures' documentation.
-
-* `run-qemu.sh` - see discussion about QEMU below
-
-* `mips`, `rumprun` - instructions to build the docker image for each respective
-  CI target
-
-# CI Systems
-
-Currently this repository leverages a combination of Travis CI and AppVeyor for
-running tests. The triples tested are:
-
-* AppVeyor
-  * `{i686,x86_64}-pc-windows-{msvc,gnu}`
-* Travis
-  * `{i686,x86_64,mips,aarch64}-unknown-linux-gnu`
-  * `x86_64-unknown-linux-musl`
-  * `arm-unknown-linux-gnueabihf`
-  * `arm-linux-androideabi`
-  * `{i686,x86_64}-apple-{darwin,ios}`
-  * `x86_64-rumprun-netbsd`
-  * `x86_64-unknown-freebsd`
-  * `x86_64-unknown-openbsd`
-
-The Windows triples are all pretty standard, they just set up their environment
-then run tests, no need for downloading any extra target libs (we just download
-the right installer). The Intel Linux/OSX builds are similar in that we just
-download the right target libs and run tests. Note that the Intel Linux/OSX
-builds are run on stable/beta/nightly, but are the only ones that do so.
-
-The remaining architectures look like:
-
-* Android runs in a [docker image][android-docker] with an emulator, the NDK,
-  and the SDK already set up. The entire build happens within the docker image.
-* The MIPS, ARM, and AArch64 builds all use the QEMU userspace emulator to run
-  the generated binary to actually verify the tests pass.
-* The MUSL build just has to download a MUSL compiler and target libraries and
-  then otherwise runs tests normally.
-* iOS builds need an extra linker flag currently, but beyond that they're built
-  as standard as everything else.
-* The rumprun target builds an entire kernel from the test suite and then runs
-  it inside QEMU using the serial console to test whether it succeeded or
-  failed.
-* The BSD builds, currently OpenBSD and FreeBSD, use QEMU to boot up a system
-  and compile/run tests. More information on that below.

-
-## QEMU
-
-Lots of the architectures tested here use QEMU in the tests, so it's worth going
-over all the crazy capabilities QEMU has and the various flavors in which we use
-it!
-
-First up, QEMU has userspace emulation where it doesn't boot a full kernel, it
-just runs a binary from another architecture (using the `qemu-<arch>` wrappers).
-We provide it the runtime path for the dynamically loaded system libraries,
-however. This strategy is used for all Linux architectures that aren't intel.
-Note that one downside of this QEMU system is that threads are barely
-implemented, so we're careful to not spawn many threads.
-
-For the rumprun target the only output is a kernel image, so we just use that
-plus the `rumpbake` command to create a full kernel image which is then run from
-within QEMU.
-
-Finally, the fun part, the BSDs. Quite a few hoops are jumped through to get CI
-working for these platforms, but the gist of it looks like:
-
-* Cross compiling from Linux to any of the BSDs seems to be quite non-standard.
-  We may be able to get it working but it might be difficult at that point to
-  ensure that the libc definitions align with what you'd get on the BSD itself.
-  As a result, we try to do compiles within the BSD distro.
-* On Travis we can't run a VM-in-a-VM, so we resort to userspace emulation
-  (QEMU).
-* Unfortunately on Travis we also can't use KVM, so the emulation is super slow.
-
-With all that in mind, the way BSD is tested looks like:
-
-1. Download a pre-prepared image for the OS being tested.
-2. Generate the tests for the OS being tested. This involves running the `ctest`
-   library over libc to generate a Rust file and a C file which will then be
-   compiled into the final test.
-3. Generate a disk image which will later be mounted by the OS being tested.
-   This image is mostly just the libc directory, but some modifications are made
-   to compile the generated files from step 2.
-4. The kernel is booted in QEMU, and it is configured to detect the libc-test
-   image being available, run the test script, and then shut down afterwards.
-5. Look for whether the tests passed in the serial console output of the kernel.
-
-There's some pretty specific instructions for setting up each image (detailed
-below), but the main gist of this is that we must avoid a vanilla `cargo run`
-inside of the `libc-test` directory (which is what it's intended for) because
-that would compile `syntex_syntax`, a large library, with userspace emulation.
-This invariably times out on Travis, so we can't do that.
-
-Once all those hoops are jumped through, however, we can be happy that we're
-testing almost everything!
-
-Below are some details of how to set up the initial OS images which are
-downloaded. Each image must be enabled have input/output over the serial
-console, log in automatically at the serial console, detect if a second drive in
-QEMU is available, and if so mount it, run a script (it'll specifically be
-`run-qemu.sh` in this folder which is copied into the generated image talked
-about above), and then shut down.
-
-### QEMU setup - FreeBSD
-
-1. Download CD installer (most minimal is fine)
-2. `qemu-img create -f qcow2 foo.qcow2 2G`
-3. `qemu -cdrom foo.iso -drive if=virtio,file=foo.qcow2 -net nic,model=virtio -net user`
-4. run installer
-5. `echo 'console="comconsole"' >> /boot/loader.conf`
-6. `echo 'autoboot_delay="0"' >> /boot/loader.conf`
-7. look at /etc/ttys, see what getty argument is for ttyu0
-8. edit /etc/gettytab, look for ttyu0 argument, prepend `:al=root` to line
-   beneath
-
-(note that the current image has a `freebsd` user, but this isn't really
-necessary)
-
-Once that's done, arrange for this script to run at login:
-
-```
-#!/bin/sh
-
-sudo kldload ext2fs
-[ -e /dev/vtbd1 ] || exit 0
-sudo mount -t ext2fs /dev/vtbd1 /mnt
-sh /mnt/run.sh /mnt
-sudo poweroff
-```

-### QEMU setup - OpenBSD
-
-1. Download CD installer
-2. `qemu-img create -f qcow2 foo.qcow2 2G`
-3. `qemu -cdrom foo.iso -drive if=virtio,file=foo.qcow2 -net nic,model=virtio -net user`
-4. run installer
-5. `echo 'set tty com0' >> /etc/boot.conf`
-6. `echo 'boot' >> /etc/boot.conf`
-7. Modify /etc/ttys, change the `tty00` at the end from 'unknown off' to
-   'vt220 on secure'
-8. Modify same line in /etc/ttys to have `"/root/foo.sh"` as the shell
-9. Add this script to `/root/foo.sh`
-
-```
-#!/bin/sh
-exec 1>/dev/tty00
-exec 2>&1
-
-if mount -t ext2fs /dev/sd1c /mnt; then
-  sh /mnt/run.sh /mnt
-  shutdown -ph now
-fi
-
-# limited shell...
-exec /bin/sh < /dev/tty00
-```
-
-10. `chmod +x /root/foo.sh`

-//! Simple script to verify the coding style of this library
-//!
-//! ## How to run
-//!
-//! The first argument to this script is the directory to run on, so running
-//! this script should be as simple as:
-//!
-//! ```notrust
-//! rustc ci/style.rs
-//! ./style src
-//! ```
-//!
-//! ## Guidelines
-//!
-//! The current style is:
-//!
-//! * No trailing whitespace
-//! * No tabs
-//! * 80-character lines
-//! * `extern` instead of `extern "C"`
-//! * Specific module layout:
-//!     1. use directives
-//!     2. typedefs
-//!     3. structs
-//!     4. constants
-//!     5. f! { ... } functions
-//!     6. extern functions
-//!     7. modules + pub use
-//!
-//! Things not verified:
-//!
-//! * alignment
-//! * 4-space tabs
-//! * leading colons on paths
