[pietroalbini]

This PR bumps the LLVM version we use on our macOS and Windows CI to 10.0.0, fixing a breakage we noticed today:

I uploaded both the new tarballs to our mirrors bucket.

Fixes CI.

We probably want to bump the linux clang builders to 10.0 at the same time? That's a perf-sensitive change (just like this one) though I imagine.

e.g.,

rust/src/ci/docker/host-x86_64/dist-x86_64-linux/build-clang.sh

Line 7 in d02a209

LLVM=llvmorg-9.0.0

[pietroalbini]

Uh I thought we were using gcc on Linux :/

Will update that too (this PR will take forever to land...).

@bors rollup=never

This is a perf-sensitive change (as well as a non-minor CI configuration change).

[pietroalbini]

Bumped LLVM on Linux too.

Haven't the download urls moved to the GitHub with LLVM 10?
Also we should be using LLVM 10.0.1 which has couple bug fixes.

[pietroalbini]

@mati865 I couldn't find neither the Windows installer nor the clang+llvm macOS tarball for 10.1.0.

[pietroalbini]

The latest failure was because LLVM 9's x86_64-darwin-apple was renamed in LLVM 10 to x86_64-apple-darwin. Fixed the URL scheme in the latest commit.

Haven't the download urls moved to the GitHub with LLVM 10?

Yes, but I mirrored them on ci-mirrors.rust-lang.org anyway.

Right, I had forgot they don't make prebuild binaries for point releases for Windows. Linux and mac 10.0.1 are available: https://github.com/llvm/llvm-project/releases/tag/llvmorg-10.0.1

[pietroalbini]

Let's keep the version in sync between Linux/macOS and Windows, unless there are 10.1.0 bugfixes affecting us directly.
