We do have reasonably good coverage with tests/tcg/cris but of course without a compiler we can't build them. Both nios2 and microblaze have build-toolchain scripts which can be used to re-create containers. However my preference is having pre-built toolchains hosted by others like we do for loongarch, hexagon, xtensa and tricore. Then the docker image can simply curl them into an image. --=20 Alex Benn=C3=A9e Virtualisation Tech Lead @ Linaro
