Toolchain CI regression reports

Linaro continuously builds and tests the GNU and LLVM toolchains on Arm. When a code change introduces a correctness, performance, or code-size regression, the CI bisects it to the offending commit and opens a regression report. These pages show the live status of those reports.

The CI watches upstream projects such as binutils, gcc, gdb, glibc, qemu, and llvm, and exercises their testsuites on Arm hardware — including the Fujitsu LLVM testsuite extension used for Flang validation.

It runs across a broad set of builders and boards (for example Graviton3 servers, x86_64 builders, Ampere, Qualcomm, SynQuacer, and Windows on Arm machines) so regressions are caught early and can be tracked back to a single guilty commit.

Signed-in users can open the full TCWG-CI home with monitored repositories, testsuites, and live project counters. Customers with a Flang Viewer seat can also unlock Flang dashboard details.
