[llvm-dev] Marking lit::shtest-format.py unsupported on PS4?, Re: buildbot failure in LLVM on llvm-clang-lld-x86_64-scei-ps4-ubuntu-fast

[via llvm-dev]

It fails probably a couple times a day on our internal merge bots, but I think that's still in the Linux-target stage.  I haven't been tracking closely.  It's annoying but hasn't been irritating enough to track down yet, if you know what I mean.  We just finished finding and fixing the random xray failure, which was more frequent.
I'll prod our merge monitors about this, but if anybody else comes up with a fix, we won't mind. ☺

FWIW, I've seen it fail on some of my commits too, but I don't remember whether it was on the PS4 bot exclusively or not. Anyway, my understanding is that this test shouldn't inherently have different behaviour on PS4 specifically, but I could be mistaken. I suspect it's something more general to do with the configuration of the bot.

I've had a suspicion for a while that it's unstable *everywhere*. At
least, I've seen it fail on out-of-tree bots intermittently but haven't
had time to investigate. It certainly seems to fail very infrequently
though.
