[PATCH v3 00/31] testing/next pre-PR (hexagon, tricore, misc)

[Alex Bennée]

Hi,

I was planning to cut the PR from v2 but I needed to squash a couple
of remaining problems with the hexagon build and also when attempting
to use clang to build the x86 tests. As a result here is a v3 that:

  - drops the signals stress test as it still triggers issues
    - sanitizier fail on __get_user(*get_freg(env, i), &sc->fpregs.fprs[i]);
    - qemu-s390x on s390x segs around 4% of the time
  - skip clang for building i386/x86_64 tests (falls back to docker)
  - tweak the hexagon image to include ninja/git

The following still need review:

 - tests/tcg: don't allow clang as a cross compiler
 - tests/tcg: fix missing return
 - tests/tcg: don't iterate through other arch compilers

[PATCH v3 04/31] tests/docker: allow "update" to add the current user

[Alex Bennée]

The current user functionality is used for cross compiling to avoid
complications with permissions when building test programs. However
for images that come from the registry we still need the ability to
add the user after the fact.

[PATCH v3 06/31] docker: Add Hexagon image

[Alex Bennée]

From: Alessandro Di Federico <ale@rev.ng>

This image is a little special because it takes a long time to build.
As such most users don't want to be doing that and just pull random
binaries from the ether as intended by the container gods. This
involves someone with credentials and a beefy machine running:

  make docker-image-debian-hexagon-cross V=1 NOCACHE=1 J=30
  docker tag qemu/debian-hexagon-cross registry.gitlab.com/qemu-project/qemu/qemu/debian-hexagon-cross
  docker push registry.gitlab.com/qemu-project/qemu/qemu/debian-hexagon-cross

With a suitable binary in the "cloud" a normal user will run:

  make docker-image-debian-hexagon-cross

or have it run for them through the dependency mechanism of our
over-engineered makefiles and get the binary they wanted. There are a
few wrinkles of course including needing to tweak the final image to
have the credentials of the user so we can actually do our cross
compiles.

[PATCH v3 08/31] gitlab: add build-user-hexagon test

[Alex Bennée]

We special case this as the container with the cross compiler for the
tests takes so long to build it is manually uploaded into the
registry.

[PATCH v3 09/31] tests/tcg: don't iterate through other arch compilers

[Alex Bennée]

There should only be one compiler per architecture. Those cases where
the same compiler can deal with a different architecture should be
explicitly set for both cross_cc and docker configurations. Otherwise
you get strangeness like:

  --cross-cc-aarch64=/bin/false

causing the logic to attempt to use a locally available
arm-linux-gnueabihf-gcc rather than forcing the use of the docker
image which is what is implied by the command line option.

[PATCH v3 11/31] tests/tcg: Add docker_as and docker_ld cmds

[Alex Bennée]

From: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>

At least for the TriCore target no easily available c compiler exists.
Thus we need to rely on "as" and "ld". This allows us to run them
through the docker image. We don't test the generation capabilities of
docker images as they are assumed to work.

[PATCH v3 12/31] tests/tcg: Run timeout cmds using --foreground

[Alex Bennée]

From: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>

when trying to run successful short tests from the Makefile timeout would not
terminate. Rather it would wait until the time runs out. Excerpt from the
manpage:

--foreground
    when not running timeout directly from a shell prompt,
    allow COMMAND to read from the TTY and get TTY signals; in this mode, chil‐
    dren of COMMAND will not be timed out

[PATCH v3 13/31] hw/tricore: Add testdevice for tests in tests/tcg/

[Alex Bennée]

From: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>

this device is used to verify the correctness of regression tests by
allowing guests to write their exit status to this device. This is then
used by qemu to exit using the written status.

[PATCH v3 15/31] configure: Emit HOST_CC to config-host.mak

[Alex Bennée]

From: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>

this is needed by the tricore-tcg-tests as tricore-gcc is not easily
available. Thus we rely on the HOST_CC to do the preprocessing of the
tricore assembly files.

[PATCH v3 16/31] tests/tcg/tricore: Add macros to create tests and first test 'abs'

[Alex Bennée]

From: Bastian Koppelmann <kbastian@mail.uni-paderborn.de>

This kind of tests is inspired by the riscv-tests repository. This adds
macros that makes it easy to create single instruction self containing
tests.

It is achieved by macros that create a test sequence for an
instruction and check for a supplied correct value. If the value is correct the
next instruction is tested. Otherwise we jump to fail handler that writes is
test number as a status code back to qemu that then exits on that status code.
If all tests pass we write back 0 as a status code and exit.

[PATCH v3 26/31] tests/docker: gcc-10 based images for ppc64{, le} tests

[Alex Bennée]

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

A newer compiler is needed to build tests for Power10 instructions. As
done for arm64 on c729a99d2701, a new '-test-cross' image is created for
ppc64 and ppc64le. As done on 936fda4d771f, a test for compiler support
is added to verify that the toolchain in use has '-mpower10'. Finally,
Unused images (docker-power-cross and docker-ppc64-cross) are removed.

[PATCH v3 28/31] cirrus.yml: Fix the MSYS2 task

[Alex Bennée]

From: Thomas Huth <thuth@redhat.com>

The MSYS2 task in the Cirrus-CI is currently failing with error messages
like this:

 warning: database file for 'ucrt64' does not exist (use '-Sy' to download)
 :: Starting core system upgrade...
  there is nothing to do
 :: Starting full system upgrade...
 error: failed to prepare transaction (could not find database)

Seems like it can be fixed by switching to a newer release and by refreshing
the database one more time after changing the /etc/pacman.conf file.

[PATCH v3 30/31] tests/tcg: don't allow clang as a cross compiler

[Alex Bennée]

Currently there are two problems.

The first is clang generates a preamble (that is always executed) to
stack xmm registers. This causes a ILLOP on the x86_64 softmmu tests
as SSE isn't enabled.

The second is the inline assembler in test-i386.c breaks clangs
compiler and I don't know how to fix it. Even with Theodore's patch
series (D5741445-7EFD-4AF1-8DB2-E4AFA93CBB1A@icloud.com) I still get
compiler failures.

For now lets just skip clang and allow it to fall back to the
containers which we know have compilers which work.

Otherwise you run into hilarity like trying when cross compiling a 32
bit ARM build on a 64 bit system trying to use host_cc to build 32 bit
test cases.
