You can run qemu-system-arm under qemu-system-s390 with vx=on ;) I'll try to give this a churn one I figure out what to apply where. thanks > > > r~ > > > Richard Henderson (3): > tcg/s390: Change FACILITY representation > tcg/s390: Merge TCG_AREG0 and TCG_REG_CALL_STACK into TCGReg > tcg/s390: Implement vector operations > > tcg/s390/tcg-target.h | 92 ++-- > tcg/s390/tcg-target.opc.h | 5 + > tcg/s390/tcg-target.inc.c | 862 +++++++++++++++++++++++++++++++++++--- > 3 files changed, 864 insertions(+), 95 deletions(-) > create mode 100644 tcg/s390/tcg-target.opc.h > -- Thanks, David / dhildenb

It seems there is a disconnect between glibc and the kernel, and some distros have fixed it and some have not. It's still broken in upstream glibc. I have added an ifndef to the branch, but you can fix it locally by changing to HWCAP_S390_VXRS. r~

Where are the arm sve tests located, so I can run them? (are they in tests/tcg?) thanks! -- Thanks, David / dhildenb
