[RFC PATCH 0/3] tests/tcg/ppc64le: paddi tests

[matheus . ferst]

From: Matheus Ferst <matheus.ferst@eldorado.org.br>

Based-on: <20210413211129.457272-1-luis.pires@eldorado.org.br>

This series adds gcc-10 based images to enable the build of tests with Power10
instructions. Then two tests for paddi are added:
- The first one checks a weird behavior observed on POWER10 Functional Simulator
  1.1.0, where the 34-bit immediate is treated as a 32-bits one;
- The second one exercises the R=1 path of paddi, where CIA is used instead of 
RA.
  The test is failing with the current implementation because we use cpu_nip,
  which is not updated all the time. Luis already has the fix, it should be
  applied on the next version of his patch series.

The main reason to submit this patch as an RFC first is the docker part. I would
lie if I tell you that I understand half of what is going on there.
 - 'make docker-test-tcg' fails, but apparently on unrelated things;
 - 'make docker-run-test-tcg@debian-ppc64el-cross' passes, but it looks
   like the test is skipped?
 - 'make check-tcg' runs the test and passes (with the fix in place for the
   second).

Finally, get_maintainer.pl found no maintainers for
tests/tcg/ppc64{,le}/Makefile.target. Would it be Mr. Gibson?

Thanks,
Matheus K. Ferst
