I've re-written that section as: The `tests/tcg` directory still contains a number of source files we don't build. The cris and openrisc directories contain user-space tests which just need the support of a toolchain and the relevant Makefile plumbing to be added. The lm32, mips and xtensa targets have a set of tests that need a system emulator. Aside from adding the compilers as docker images some additional work is needed to handle the differences between plain linux-user tests which can simply return an exit code to getting the results from a qemu-system emulation. Some architectures have semi-hosting support already for this while others report their test status over a simple serial link which will need to be parsed and handled in the `run-%:` test rule. How is that? Any chance you could look into what it would take to package up the xtensa toolchain in a docker container? Are they simply tarballs of binaries? -- Alex Bennée
