This skips bumping Windows sccache because we run into compilation failures when
doing so (-m32 not supported by clang-cl?). Not clear on cause, but seems
easiest to just hold back.
This should avoid PGO-related failures encountered on Linux, and more broadly
seems like a good idea on other platforms as well (though it is likely not
necessary right this moment).
This shows up to 5% less instruction counts on multiple benchmarks, and up to
19% wins on the -j1 wall times for rustc self-compilation.
We can afford to spend the extra cycles building LLVM essentially once more for
the x86_64-unknown-linux-gnu CI build today. The builder finishes in around 50
minutes on average, and this adds just 10 more minutes. Given the sizeable
improvements in compiler performance, this is definitely worth it.
Build aarch64-apple-ios-sim as part of the full macOS build
Part of the [MCP 428](https://github.com/rust-lang/compiler-team/issues/428) to promote this target to Tier 2.
This adds the aarch64-apple-ios-sim target as a tier 2 target, currently cross-compiled from our x86_64 apple builders. The compiler team has approved the addition per the MCP noted above, and the infrastructure team has not raised concerns with this addition at this time (as the CI time impact is expected to be minimal; this is only building std).
The LLD + ThinLTO __morestack bug has been fixed in 12.0.1, so
we can now update our clang version. This also means that we no
longer need to build Python 2.
The only change here is a fix for `sys.platform` on Linux. Python 3.3
changed the API to return "linux" instead of "linux2"/"linux3", so this
commit uses `.startswith("python")` to make the code work on Python 3
without breaking Python 2.
Use HTTPS links where possible
While looking at #86583, I wondered how many other (insecure) HTTP links were in `rustc`. This changes most other `http` links to `https`. While most of the links are in comments or documentation, there are a few other HTTP links that are used by CI that are changed to HTTPS.
Notes:
- I didn't change any to or in licences
- Some links don't support HTTPS :(
- Some `http` links were dead, in those cases I upgraded them to their new places (all of which used HTTPS)
Line numbers aligned with content
We had the issue a few times in the past where the source code pages' content wasn't aligned with the line numbers but completely below. This test will prevent this change to go unnoticed.
The first commit comes from https://github.com/rust-lang/rust/pull/86541 so it needs it to be merged first.

Fix CI to fetch master on beta channel
This forward-ports a fix from the beta channel (landing in #86413, hopefully) to master so that we don't need to apply it on each round of backports.
This bug also demonstrates that our channel-checking is a bit insufficient -- stable is checked, but beta has some of its own peculiarities currently and isn't checked. But this does not attempt to adjust for that; we likely can't afford to run both beta and stable channels by CI and the current state here seems OK for now.
r? `@pietroalbini`
During the 1.52 release process we had to deal with some commits that
passed the test suite on the nightly branch but failed on the beta or
stable branch. In that case it was due to some UI tests including the
channel name in the output, but other changes might also be dependent on
the channel.
This commit adds a new CI job that runs the Linux x86_64 test suite with
the stable branch, ensuring nightly changes also work as stable.
Add eslint checks to CI
It also allowed me to fix some potential issues that went unnoticed. Having this process automated will hopefully prevent us to add more errors. :)
