The QEMU project is currently moving its bug tracking to another system.
For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting older bugs to "Incomplete" now.
If the bug has already been fixed in the latest upstream version of QEMU,
then please close this ticket as "Fix released".
If it is not fixed yet and you think that this bug report here is still
valid, then you have two options:
1) If you already have an account on gitlab.com, please open a new ticket
for this problem in our new tracker here:
https://gitlab.com/qemu-project/qemu/-/issues
and then close this ticket here on Launchpad (or let it expire auto-
matically after 60 days). Please mention the URL of this bug ticket on
Launchpad in the new ticket on GitLab.
2) If you don't have an account on gitlab.com and don't intend to get
one, but still would like to keep this ticket opened, then please switch
the state back to "New" within the next 60 days (otherwise it will get
closed as "Expired"). We will then eventually migrate the ticket auto-
matically to the new system (but you won't be the reporter of the bug
in the new system and thus won't get notified on changes anymore).
Thank you and sorry for the inconvenience.

Title:
[ppc64le] qemu behavior differs from ppc64le hardware
Status in QEMU:
Incomplete
Bug description:
I have some code which passes my test suite on PPC64LE hardware when
compiled with GCC 10, but the saem binary fails with both qemu-ppc64le
4.2 (on Fedora 32) and qemu-ppc64le-static 5.0.0 (Debian testing).
I'm not getting any errors about illegal instructions or anything,
like that; the results are just silently different on qemu.
I've generated a reduced test case, which is attached along with the
binaries (both are the same code, one is just statically linked).
They should execute successufully on PPC64LE hardware, but on qemu
they hit a __builtin_abort (because the computed value doesn't match
the expected value).
Without being familiar with PPC assembly I'm not sure what else I can
do, but if there is anything please let me know.
