test-pixels failing on all big endian architectures

[chewi]

Both Gentoo and Debian have found that test-pixels fails on all big endian architectures, including ppc32, ppc64, hppa, sparc, and s390x. Debian's logs show that m68k is working, but they disable the tests on that architecture.

See Debian's package logs.

The swap32 macro wasn't working as intended as it was being fed signed integers.

I've fixed that particular issue now, but I still cannot guarantee that the test will pass or that this will even work on those systems. I've never tested this before on big endian.

That's okay, I wouldn't expect you to. Thanks for jumping on this quickly. We'll give it a try.

Sorry, I forgot to report back. I've been told that it sadly didn't work. We only need this for Weston, which has other big endian issues that aren't getting solved in a hurry, but I figured I should reopen this anyway.

That might be useful to have.

I'm just the messenger here, but I've passed that on.

I was looking at debian's package logs that you linked to earlier. Gentoo has that file attached, and it didn't really shed any light on the issue.

I'll need to set up something with qemu to fix this, or wait until sr.ht ci gets a big-endian arch.
