ci: Upgrade ubuntu:25.04 for the PowerPC64LE test

2025-07-24T10:52:58+00:00

Update the last remaining image. For this to work, the `QEMU_CPU=POWER8` configuration needed to be dropped to avoid a new SIGILL. Doing some debugging locally, the crash comes from an `extswsli` (per `powerpc:common64` in gdb-multiarch) in the `ld64.so` available with PowerPC, which qemu rejects when set to power8. Testing a build with `+crt-static` hits the same issue at a `maddld` in `__libc_start_main_impl`. Rust isn't needed to reproduce this: $ cat a.c #include int main() { printf("Hello, world!\n"); } $ powerpc64le-linux-gnu-gcc a.c $ QEMU_CPU=power8 QEMU_LD_PREFIX=/usr/powerpc64le-linux-gnu/ ./a.out qemu: uncaught target signal 4 (Illegal instruction) - core dumped Illegal instruction So the cross toolchain provided by Debian must have a power9 baseline rather than rustc's power8. Alternatively, qemu may be incorrectly rejecting these instructions (I can't find a source on whether or not they should be available for power8). Testing instead with the `-musl` toolchain and ppc linker from musl.cc works correctly. In any case, things work with the default qemu config so it seems fine to drop. The env was originally added in 5d164a4edafb ("fix the powerpc64le target") but whatever the problem was there appears to no longer be relevant.

ci: Update to the latest ubuntu:25.04 Docker images

2025-07-24T06:42:53+00:00

This includes a qemu update from 8.2.2 to 9.2.1 which should hopefully fix some bugs we have encountered. PowerPC64LE is skipped for now because the new version seems to cause a number of new SIGILLs.

ci: Make CI configuration more similar to `libm`

2025-04-19T03:49:29+00:00

Apply a handful of changes to reduce the diff between the two: * Cancel running jobs on new pushes * Enable log color and backtraces * Add timeouts * Specify CI runner versions * Add an armv7 job * Replace the name NO_STD with BUILD_ONLY * Update the extension to the canonical .yaml * Set AR_ and CC_ environments in docker * Install requirements to build MPFR

Update the Ubuntu docker image to the latest version

Add a way to run tests on non-linux machines

2024-04-19T15:49:23+00:00

Allow using the `rust-lang/rust:nightly` docker image to run tests in cases where the host rust and cargo cannot be used, such as non-linux hosts.

Upgrade all docker containers to 18.04

2019-04-02T15:39:19+00:00

drop binfmt_misc dependency

2017-10-07T20:19:37+00:00

Instead use the Cargo runner feature. The binfmt_misc approach requires running a privileged container for setup. Not all docker setups support privileged containers so the test suite should be more accessible with this change as no privileged container is needed.

Fix apt 404s in Docker

2016-11-12T22:08:13+00:00

`apt update` and `apt install` should be in the same Docker RUN statement, otherwise `apt update` will be cached and `apt install` will 404 if a package no longer exists.

fix the powerpc64le target

2016-10-14T14:59:21+00:00

by selecting a CPU that's compatible with the instructions that `rustc` generates

cache Cargo artifacts

2016-09-30T22:39:36+00:00

notable changes in the docker-based testing infrastructure - the docker containers can now modify $CARGO_HOME, to re-use the outer Cargo registry, and the target directory to re-use build artifacts. - the docker containers are removed when their execution finishes because it's no longer necessary to re-start them to inspect them because all the interesting output is in the outer target directory
