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?
