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

Title:
qemu-user can't run some ppc binaries
Status in QEMU:
New
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)
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
