I am not a core dev, but I set up a CI for tcc: https://gitlab.com/giomasce/tinycc/pipelines Unfortunately it is currently broken. I believe the CI is broken, not tcc, because it wasn't broken before my last round of CI script maintenance. I'll try to fix them as soon as I have some time, but if someone wants to check them out in the meantime I won't complain. The thing is currently set up with an automatic script on a server of mine that periodically checks for new commits and sends them to the repository on GitLab (branch "test"). Those scripts automatically compile and run tcc's tests in the native GitLab CI environment and on five different Debian systems of different architectures by mean of QEMU whole system emulation (i386, amd64, armhf, arm64 and riscv64). Currently armhf fails with "Illegal instruction", and I don't know if the problem is QEMU emulation or tcc itself, because the same commit did work before I did my last round of changes. riscv64 has a failing test, and that could be a genuine tcc bug. If so, it is probably introduced by recent "win32: long double as distinct C-type" commit. Broken test is "70_floating_point_literals", see the log[1]. [1] https://gitlab.com/giomasce/tinycc/-/jobs/507946108 As soon as I have some time, I'd like to fix these problems and eventually support Windows and macOS too. I believe this architecture with QEMU running in GitLab CI can work, but suitable Windows and macOS images have to be prepared and compilation scripts adapted. QEMU TCG emulation is slowish, but if we prepare images with a snapshot so that the VM doesn't have to go through the whole boot sequence it might be reasonable.
