Hi Richard, hi Ilya,
with the recent QEMU master branch (commit 701ed34), I'm now seeing failures
in Travis:
https://app.travis-ci.com/github/huth/qemu/jobs/593786529#L14411
Everything was still fine a couple of days ago (commit fb7e799):
https://app.travis-ci.com/github/huth/qemu/builds/259755664
... so it seems this is likely related to this pull request. Could you
please have a look?
Thanks,
Thomas

Hmm maybe the code motion has revealed another form of the compiler bug.
I guess these bugs don't die, they just refract.

I would expect this to be (temporarily) fixed by [1], but we probably
don't set GITLAB_CI in Travis. Would it make sense to set it? It looks
as if this variable is currently used only to skip certain tests.
If not, then maybe split it into QEMU_CI, GITLAB_CI and TRAVIS_CI?

Ah, ok, so this test has issues in gitlab, too!
For Travis, I think we should either check the CI or TRAVIS environment
variables:

*sigh* yeah the test is flaky but this is a subtly different failure
mode. All the gitlab failures I saw where the test triggering the abort
rather than the assert catch we have here.

Thankfully our s390x.ci.qemu.org has the same version gcc installed, and I was able to
reproduce this. But only once -- it's irregular and very low frequency.
The code generated by gcc is correct and easy to inspect, since cpu_exec_setjmp is now
quite small:
00000000000f3250 <cpu_exec_setjmp.isra.0>:
f3250: eb 6f f0 30 00 24 stmg %r6,%r15,48(%r15)
f3256: a7 39 00 00 lghi %r3,0
f325a: e3 f0 ff 58 ff 71 lay %r15,-168(%r15)
// Save cpu to stack+160.
f3260: e3 20 f0 a0 00 24 stg %r2,160(%r15)
f3266: 41 20 20 f0 la %r2,240(%r2)
f326a: c0 e5 ff fb 10 eb brasl %r14,55440 <__sigsetjmp@plt>
f3270: ec 26 00 0d 00 7e cijne %r2,0,f328a <cpu_exec_setjmp.isra.0+0x3a>
// Reload cpu for cpu_exec_loop().
f3276: e3 20 f0 a0 00 04 lg %r2,160(%r15)
f327c: c0 e5 ff ff fb ee brasl %r14,f2a58 <cpu_exec_loop.isra.0>
f3282: eb 6f f0 d8 00 04 lmg %r6,%r15,216(%r15)
f3288: 07 fe br %r14
// Load tls pointer and current_cpu address.
f328a: b2 4f 00 10 ear %r1,%a0
f328e: c0 20 00 0a 35 9d larl %r2,239dc8 <current_cpu@@Base+0x239dc8>
f3294: eb 11 00 20 00 0d sllg %r1,%r1,32
f329a: e3 20 20 00 00 04 lg %r2,0(%r2)
f32a0: b2 4f 00 11 ear %r1,%a1
// Reload cpu for comparison
f32a4: e3 30 f0 a0 00 04 lg %r3,160(%r15)
// cpu == current_cpu
f32aa: e3 32 10 00 00 20 cg %r3,0(%r2,%r1)
f32b0: a7 84 00 12 je f32d4 <cpu_exec_setjmp.isra.0+0x84>
...
The only way I can imagine that this comparison fails is if we have corrupted the stack in
some way. I have not been able to induce failure under any sort of debugging, and I can't
imagine where irregular corruption would have come from.
