@dalias @astraluma @hipsterelectron CI is not a substitute for writing portable code with reliable local incremental builds. But I need to know that SVE vectorization isn't spoiled and that the code remains correct when targeting GPUs from 3 vendors, that the build isn't broken on Windows or MacOS, etc. In a project with more than a couple contributors, having maintainers switch branches and manually build and test on a suite of different hardware and OS environments is untenable.
