This series replaces TCG tests makefiles with meson, with the
goal of having something more readable and maintainable in the long term.
Also it closes the gap that tcg tests had with the rest of tests, by integrating
them with meson directly.

It covers all existing tests for all architectures, including
user/system/multiarch-user/multiarch-system. It implements all requirements
listed on original thread [1].

[1] https://lore.kernel.org/qemu-devel/87wlwfsay4.fsf@draig.linaro.org/

We also have for free:
- correct and complete dependencies for any test, including:
  scripts, c.inc, headers, reference files and binaries/plugins.
- catch test declaration issues at configure time vs test time.
- proper data types for variables instead of string expansion with make.

Series first introduce the meson machinery needed in tests/tcg/meson.build, step
by step. Then it adds support for all existing archs. Finally, we remove
Makefiles and configure bits.

Usage:

```
make check-tcg
make check-tcg-aarch64-linux-user
make check-tcg-aarch64-softmmu

make tcg-tests

ninja clean
./pyvenv/bin/meson test aarch64-softmmu-asid2 --verbose
```

A few items were left for further work (out of scope for this series):
- xtensaeb: didn't find how to cross compile for this architecture with what we
  have now in container debian-xtensa-cross. Tips are welcome.
- tricore: implemented but reverted as all tests seem to hang. To be
  investigated.
- riscv64/interruptedmemory.S is hanging. To be investigated.
- i386/test-i386-fprem.c is deactivated for now. It's broken (output does not
  match bare metal result) and is the slowest test we have. To be refactored and
  fixed.

v3
--

- add all architectures
- reduce number of plugins tests (only add one test for each plugin from
  multiarch pool)
- add depends for executable - allow to depend on a custom target for generated
  headers (x86_64 mmx, avx)
- add new tests added since last version for aarch64 (mte + gpc)
- refactor series to keep all arch files at end
- add docker host architecture selection

v2
--

- s/mispell/misspell
- moved comment about why we remove 'lib' prefix for plugins
- if user declare a wrong entry in a dictionary, list possible keys
- build tests by default (with 'all' target), as long as cross compiler is
  natively installed, to avoid triggering a container build.
- reword some comments based on reviewers feedback
- always declare all tests and avoid "per config" errors (no 'if' in arch files)
- move compiler feature and gdb version checks directly in tests/tcg/meson.build
- add support for cross containers
- add top target 'tcg-tests' to rebuild all tests

Thanks for the report. I just tried that on debian for now.

Also, for s390x, I noticed that some tests are relying on roms/SLOF/...
headers, which are not available if submodules are not initialized.
Probably another corner case to cover.

I'll take a look at how we detected all this before, and gracefully fall
back to docker in this case.

We've got some logic in the configure script that should always initialize 
the roms/SLOF submodule when you build the s390x target:

if have_target s390x-softmmu && probe_target_compiler s390x-softmmu && \
     GIT=git "$source_path/scripts/git-submodule.sh" 
"$git_submodules_action" roms/SLOF >> config.log 2>&1; then

Is that failing in your case?

Sent v4, adding missing targets (xtensaeb + tricore) and all changes

Can these be built via ninja?

Also I noticed docs/devel/testing/main.rst needs updating for the new

Yes sure. I just listed make commands because I know some people can be
very sensitive about using anything out of make.

make tcg-tests is the same target as ninja tcg-tests.

The check targets are custom to Makefiles, because in an ideal world we
should be using meson test instead of make for this. Now that all tests
are meson native, maybe it will be time to reconsider this and
officially use meson test instead of make.

If possible, I would like to avoid duplicating the comments from
tests/tcg/meson.build in docs. Documentation tends to become obsolete,
while code itself has to stay up to date by definition.

There are plenty of examples in tests/tcg/* to find how to declare tests
if someone is looking for information. Usually, a new test will just be
a copy of an existing one.

What do you think?

For the rest, you're right, I'll update
https://www.qemu.org/docs/master/devel/testing/main.html#testing-with-make-check-tcg
to match the new commands.
