** Attachment added: "ppc binary that crashes qemu-user"
https://bugs.launchpad.net/qemu/+bug/1926202/+attachment/5492563/+files/helloworld-centos.static.ppc
** Description changed:
qemu-user v6.0.0-rc5, built in static mode, will crash for certain ppc
binaries. It seems to have something to do with glibc for some Centos
versions. The problem is easiest to see with statically-linked
binaries.
The attached Dockerfile shows how to produce a ppc binary that will
crash qemu-user. Here is how to reproduce the problem:
$ uname -m
x86_64
$ docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
$ docker build -t qemu-bug:centos -f Dockerfile.centos .
$ docker run --rm -it -v$PWD:$PWD -w$PWD qemu-bug:centos cp /helloworld-centos.static.ppc .
$ qemu-ppc version 5.2.95 (v6.0.0-rc5)
Copyright (c) 2003-2021 Fabrice Bellard and the QEMU Project developers
$ qemu-ppc-static ./helloworld-centos.static.ppc
emu: uncaught target signal 4 (Illegal instruction) - core dumped
[1] 16678 illegal hardware instruction (core dumped) qemu-ppc-static ./helloworld-centos.static.ppc
-
- I can also provide the binary if necessary.

Could you provide directly the binary to test (helloworld-

This is not a regression (reproduced with 5.2 and 5.1)
IN: strlen
0x1000d780: 7d2a03f8 cmpb r10, r9, r0
OP:
ld_i32 tmp0,env,$0xfffffffffffffff0
brcond_i32 tmp0,$0x0,lt,$L0
---- 1000d780
mov_i32 nip,$0x1000d780
mov_i32 tmp0,$0x60
mov_i32 tmp4,$0x21
call raise_exception_err,$0x2,$0,env,tmp0,tmp4
exit_tb $0x0
set_label $L0
exit_tb $0x7efd50022283
"cmpb" is define in ISA 2.05, but qemu-ppc (32bit) defines by default a
PowerPC 750 that is not ISA 2.05.
It doesn't seem QEMU supports ISA 2.05 for any 32bit PowerPC (only
POWER7 and above, that are 64bit processors).

Thanks for looking into this. What reference did you use to check which
ISA "cmpb" is in?

It's in the QEMU source, but you can check the specs:
POWER ISA 2.04 -> no cmpb
https://wiki.raptorcs.com/w/images/6/65/PowerISA_V2.04-FINAL.Public.pdf
POWER ISA 2.05 -> cmpb

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 the bug state 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" or "Confirmed" within the next 60 days (other-
wise it will get closed as "Expired"). We will then eventually migrate
the ticket automatically to the new system (but you won't be the reporter
of the bug in the new system and thus you won't get notified on changes
anymore).
Thank you and sorry for the inconvenience.

Title:
qemu-user can't run some ppc binaries
Status in QEMU:
Expired
Bug description:
qemu-user v6.0.0-rc5, built in static mode, will crash for certain ppc
binaries. It seems to have something to do with glibc for some Centos
versions. The problem is easiest to see with statically-linked
binaries.
The attached Dockerfile shows how to produce a ppc binary that will
crash qemu-user. Here is how to reproduce the problem:
$ uname -m
x86_64
$ docker run --rm --privileged multiarch/qemu-user-static --reset -p
yes
$ docker build -t qemu-bug:centos -f Dockerfile.centos .
$ docker run --rm -it -v$PWD:$PWD -w$PWD qemu-bug:centos cp
/helloworld-centos.static.ppc .
$ qemu-ppc-static --version
qemu-ppc version 5.2.95 (v6.0.0-rc5)
