71ebbe09e9 tests/docker: fix "cc" command to work with podman
Podman requires a little bit of additional magic to the uid mapping
which was already done for the normal RunCommand. We simplify the
logic by pushing it directly into the Docker::run method to avoid
instantiating an extra Docker() object and ensure the CC command
always runs as the current user.

6eed53f71b target/mips: tests/tcg: Fix target configurations for MSA tests
At this moment, the only MIPS CPUs that are emulated in QEMU and
support MSA extension are R5600 (mips32r5), and I6400/I6500 (mips64r6).
Therefore, mips32r5 and mips64r6 are the only ISAs that could support
MSA in QEMU. This means mips32r6 currently do not make much sense, and
mips32r5 support for MSA tests is needed, which is done by this patch.

d7059fd737 target/mips: tests/tcg: Add optional printing of more detailed failure info
There is a need for printing input and output data for failure cases,
for debugging purpose. This is achieved by this patch, and only if a
preprocessor constant is manually set to 1. (Assumption is that the
need for such printout is relatively rare.)

ef860047b6 tests/tcg: fix diff-out pass to properly report failure
A side effect of piping the output to head is squash the exit status
of the diff command. Fix this by only doing the pipe if the diff
failed and then ensuring the status is non-zero.

bd2c0f67e1 tests/tcg: fix up test-i386-fprem.ref generation
We never shipped the reference data in the source tree because it's
quite big (64M). As a result the only option is to generate it
locally. Although we have a rule to generate the reference file we
missed the dependency and location changes, probably because it's only
run for SLOW test runs.

c10aaaab0f tests: Fix up docker cross builds for ppc64 (BE) targets
We currently have docker cross building targets for powerpc (32-bit, BE)
and ppc64el (64-bit, LE), but not for pcp64 (64-bit, BE).  This is an
irritating gap in make check-tcg coverage so correct it.

8d8a8ab544 tests/tcg/alpha: add system boot.S
This provides the bootstrap and low level helper functions for an
alpha kernel.  We use direct access to the DP264 serial port for
test output, and hard machine halt to exit the emulation.

7ac283e963 tests/tcg/multiarch: expand system memory test to cover more
Expand the memory test to cover move of the softmmu code. Specifically
we:

  - improve commentary
  - add some helpers (for later BE support)
  - reduce boiler plate into helpers
  - add signed reads at various sizes/offsets
  - required -DCHECK_UNALIGNED

f6482872f3 tests/tcg/aarch64: add system boot.S
This provides the bootstrap and low level helper functions for an
aarch64 kernel. We use semihosting to handle test output and exiting
the emulation. semihosting's parameter passing is a little funky so we
end up using the stack and pointing to that as the parameter block.

8041650aef tests/tcg/multiarch: add support for multiarch system tests
We can certainly support some common tests for system emulation that
make use of our minimal defined boot.S support. It will still be up to
individual architectures to ensure they build so we provide a
MULTIARCH_TESTS variable that they can tack onto TESTS themselves.

b345e14053 target/xtensa: implement exclusive access option
The Exclusive Instructions provide a general-purpose mechanism for
atomic updates of memory-based synchronization variables that can be
used for exclusion algorithms.

Use cmpxchg-based implementation that is sufficient for the typical use
of exclusive access in atomic operations.

bc19449acc tests/tcg/xtensa: clean up test set
Drop test_fail: we know that exit simcall works. Now that it's not run
automatically there's no point in keeping it.
Drop test_pipeline: we're not modeling pipeline, we don't control ccount
and there's no plan to do so.
Enable test_boolean: it won't break on cores without boolean option, it
will do testing on cores with boolean option.

b9ec52188f target/xtensa: fix break_dependency for repeated resources
break_dependency incorrectly handles the case of dependency on an opcode
that references the same register multiple times. E.g. the following
instruction is translated incorrectly:

  { or a2, a3, a3 ; or a3, a2, a2 }

This happens because resource indices of both dependency graph nodes are
incremented, and a copy for the second instance of the same register in
the ending node is not done.
Only increment resource index of the ending node of the dependency.
Add test.

I've included the framework for x86_64 but it is not in this series as
it is a work in progress.

We will likely want a few common functions to make up for the fact we

banging rocks together.

I've purloined the printf function from:

  https://git.virtualopensystems.com/dev/tcg_baremetal_tests

Although I have tweaked the names to avoid confusing GCC about clashing
with builtins.

d72132c02e tests/tcg: enable cris base user-mode tests
This converts the existing Makefile into a Makefile.target and updates
it so it can be called by the tcg build system. The original Makefile
didn't set -cpu except for the v17 tests however that has broken (I
assume because linux-user is a "max" cpu) so here I force it to be
crisv17.

I've also replicated the GNU simulator targets (run-FOO-on-sim).
