The rust tests were disabled some time ago when fuchsia.googlesource.com was temporarily rate limiting git checkout requests during a high period of requests. This makes a number of attempts to avoid this issue: * It checks out Fuchsia with git filter `tree:0` to reduce download size. * It blocks downloading Fuchsia's Rust toolchain. * It adds a number of retries to requests. * It reduces the parallel git checkout threads. Since it has been a while since we updated the Fuchsia integration, it also updates: * Use the most recent commit [be532c]. * It updates to the clang commit [5e63f2]. * It updates to the Fuchsia SDK version 33.20260909.5.1. * It updates the ubuntu container to 26.04. * It renames the test job to `test-x86_64-fuchsia`. * The Fuchsia build system now requires shared libraries to be stripped. try-job: dist-various-2 try-job: test-x86_64-fuchsia [be532c]: https://fuchsia.googlesource.com/integration/+/be532c365aa6ba56b08ed684c0f8bb71960c18fd [5e63f2]: llvm/llvm-project@5e63f2c
x86: on targets that requires SSE, use those registers for ABI Now that llvm/llvm-project#142321 is fixed, we can use the vector ABI without re-introducing rust-lang/rust#139029. So this effectively reverts rust-lang/rust#141309. Since this means we are relying on the SSE target feature for the Rust ABI, we also need to turn the ABI target feature check into a hard error. If we don't do that, we'll get post-mono errors in some situations and plain miscompilations in others. Also this will cause performance regressions on LLVM 22 and 21 as those don't have the fix for llvm/llvm-project#142321. IMO that's fine. Programs will do the right thing, they will just be a bit slower due to rust-lang/rust#139029. r? @nikic Cc @tgross35
Fix test compiling Fuchsia with rust-under-test The rust tests for Fuchsia were disabled some time ago in rust-lang/rust#138690 when fuchsia.googlesource.com was temporarily rate limiting git checkout requests during a high period of requests. This makes a number of attempts to avoid this issue: * It checks out Fuchsia with git filter `tree:0` to reduce download size. * It blocks downloading Fuchsia's Rust toolchain. * It adds a number of retries to requests. * It reduces the parallel git checkout threads. Since it has been a while since we updated the Fuchsia integration, it also updates: * Use the most recent commit [be532c]. * It updates to the clang commit [5e63f2]. * It updates to the Fuchsia SDK version 33.20260909.5.1. * It updates the ubuntu container to 26.04. * It renames the test job to `test-x86_64-fuchsia`. * The Fuchsia build system now requires shared libraries to be stripped. * The Fuchsia build now requires the Rust toolchain to have the artifacts for arm64 and riscv64 to be present, even though they might not be used for this build. Note that I did use Gemini to help debug some issues, but all the code has been written by me. try-job: dist-various-2 try-job: test-x86_64-fuchsia [be532c]: https://fuchsia.googlesource.com/integration/+/be532c365aa6ba56b08ed684c0f8bb71960c18fd [5e63f2]: llvm/llvm-project@5e63f2c
