[Qemu-devel] [Bug 1828429] Re: qemu-system-aarch64 crashes with assertion failed while running GCC 9 test suite

Hi -- this looks rather like bug #1824853, which exists in QEMU 4.0 but
which we have fixed in git. Could you try with a build of QEMU from
current head-of-git to confirm that it's fixed there ?
You received this bug notification because you are a member of qemu-
devel-ml, which is subscribed to QEMU.
qemu-system-aarch64 crashes with assertion failed while running GCC 9
Status in QEMU:
I am using QEMU 4.0.0 on an x86_64 Linux 4.19.0 host, the guest is an
Aarch64 linux 5.0.0 system. The same issue occurred on QEMU 3.1.0.
While running the GCC 9.1 test suite on the guest system, QEMU crashes
qemu-system-aarch64: [...]/qemu-4.0.0/tcg/tcg.c:3952: tcg_gen_code:
Assertion `s->gen_insn_end_off[num_insns] == off' failed.
I am able to reproduce the issue reliably, which is encouraging. The
full QEMU command line is:
qemu-system-aarch64 -kernel kernel-5.0.0cbl1 -append "root=/dev/vda1
ro init=/sbin/init console=ttyAMA0" -name guest=cbl -drive
file=swap.qcow2,index=1,media=disk,format=qcow2 -machine virt -cpu
cortex-a57 -smp 4,sockets=1,cores=2,threads=2 -m size=8192 -netdev
tap,id=network0,ifname=tapcbl2,script=no,downscript=no -device virtio-
The specific GCC test that causes QEMU to crash is vldX.c run from
advsimd-intrinsics.exp; I can reproduce via "make check-gcc
If there is anything I can do to further triage the issue, or gain
more insight into what is going on, please let me know! I am eager to
help however I can.
