This patch installs sccache using apt-get in the CI container build
process rather than manually downloading it from github releases. This
makes things quite a bit simpler and means we are not manually handling
things like hash/signature verification. This is only possible now that
we are using ubuntu 24.04 by default.
The Github runner version got bumped recently and it would be good to keep
this up to date. Also debugging an issue where Github ARC is failing to
create new pods and trying to see if it might be related to outdated
versions.
This helps keep things up to date, and should not cause any issues given we do
not need to care about binary compatibility for things built in the CI
container. This patch also changes the name of the container which allows
incrementally moving jobs over after this lands.

This patch bumps the CI container to the latest LLVM Release and gets rid of
the patch that we were carrying that is in 20.1.1.

This is generally good practice if the caches won't be reused (though
arguably pedantic for the `stage1-toolchain` stage).
`docker history` on comparable images showed that this saves a few
hundred MB on stage1, and ~60MB on the `apt-get` layer of
`ci-container-agent`.
- Trailing whitespace shows up as red on my editor, so remove.
- Docker on my machine warns that having line continuations like:
```
sudo \
foo
```
is deprecated, and will become an error, so fix that up ahead of time.
This patch bumps the runner version to v2.322.0 in the CI containers.
Nothing looks suspicious in the change log, and it is important to keep
the runner up to date or we will end up with containers that cannot
connect to Github due to having a version too old.
This patch adds an agent container image on top of the normal CI
container image. They are the exact same except that the agent container
image also contains Github Runner binaries. I've split it into a
separate container as only one user of these images (the new premerge)
needs this binary installed, and it bloats the container image size
significantly (900MB->1.3GB or so).
This patch adds zlib at build time to the CI container. This is needed
to make an lldb test pass that defaults to using the system lld if it is
not explicitly enabled in LLVM_ENABLE_PROJECTS.
Fixes#123479 (by fixing the proximal cause).
This patch adds sudo to the CI container and also adds the gha user as a
member of the sudo group along with making any member of the sudo group
able to run commands as root without a password. This is primarily
intended to enable installing new software through apt-get without
having to rebuild the container.
This patch sets the default user in the linux CI container to a non-root
user, which enables properly testing a couple of features, particularly
in libcxx.
This patch adds some additional system packages to the CI container.
These are necessary for use in the new premerge workflows. The size
increase is not super small, but should be manageable with the size
increase being about 100MB.
This patch bumps the CI container LLVM version to 18.1.8. This should've
been bumped a while ago, but I just noticed that it was out of date.
This also allows us to drop a patch that we manually had to add as it is
by default included in v18.
This patch adjusts the build process for building the toolchain for the
CI container to perform more rigorous perf-training for PGO,
particularly building the entirety of LLVM as that is what showed the
best results while benchmarking. This patch also splits the job into two
stages to avoid timeouts due to the large increase in buildtime. There
are a couple other hacks added in here to make things work that we can
do away with eventually once we're able to run jobs like this on more
powerful self-hosted runners.
Only the stage2-distribution target is built by default for the
stage2 distribution installation target. This means that we don't get a
BOLT optimized binary. This patch explicitly builds the
stage2-clang-bolt target before the distribution installation target so
that the clang binary is optimized before it gets installed.
This patch adjusts the Docker container intended for CI use to contain a
PGO+ThinLTO+BOLT optimized clang. The toolchain is built within a Github
action and takes ~3.5 hours. No caching is utilized. The current PGO
optimization is fairly minimal, only running clang over hello world.
This can be adjusted as needed.
