[PATCH 0/2] tests/docker: tests/tcg/ppc64le: Newer toolchain to build tests for PowerISA v3.1 instructions

[matheus.ferst]

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

This series adds gcc-10 based images to enable the build of tests with Power10
instructions. Then, to put it to good use, a tests for the byte-reverse
instructions (implemented in 9d69cfa2faa7) is introduced.

[PATCH 1/2] tests/docker: gcc-10 based images for ppc64{,le} tests

[matheus.ferst]

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'.

You add these "power" (as opposed to "powerpc" or "ppc64" or whatever)
images here, but they don't seem to be referenced anywhere else.

I'm not really clear on what distinguishes a -cross.docker image and a
-test-cross.docker image.

Doesn't this remove all uses of the debian-pp64-cross and
debian-ppc64el-cross images, in which case you could remove the
matching docker files and so forth too, no?

I was expecting the new debian-power-test-cross to replace both
debian-powerpc-cross and debian-ppc64-cross.

The normal cross image (debian-ppc64le-cross) can cross build QEMU. The
-test-cross images are just used for building check-tcg test cases.

Yes this should be removed.

Well I assume you still want to check cross building of QEMU. Arguably
we could still use that for the test cases as well.

Maybe rename the images as:

DISTRIB-TARGET-crossbuild and DISTRIB-TARGET-crosstest-tcg?
(as it is not obvious for every contributor than 'cross' imply
emulation and not virtualization).

It's a typo. Probably worked on my machine because a correctly named image
was created outside qemu build before. I'll nuke docker and test again.

OK, I'll change for powerpc too.

But then we have the old gcc that can't handle the new instructions, which
is why I started the series :)

Oh, about nesting "ppc64-*" and "ppc64le-*" in tests/tcg/configure.sh:

We could do something like:

 >     container_hosts=x86_64
 >     container_image=debian-powerpc-test-cross
 >     container_cross_cc=${target%%-*}-linux-gnu-gcc-10

But I think it's kind of ugly to repeat container_cross_cc line. If we do
that, we can bring ppc-* too, but another line would be needed to handle
ppc64abi32-*...

Lets not over complicate it - but the ppc64/ppc64le in the same
container looks fair enough doesn't it?
