[Qemu-devel] qemu-arm fails with newer libc |

I'm trying to set up an environment where I can use a command like
qemu-arm -L /path/to/root-file-system my_program
I tried qemu from latest Debian unstable, and couldn't make it work. I
then downloaded the latest snapshot (qemu-snapshot-2007-10-29_05). I
used a recent version of the CodeSourcery toolchain.
As it is, qemu-arm fails with an error like this:
qemu: Unsupported syscall: 983045
which indicates missing TLS support. I found this patch:
http://www.freaknet.org/martin/QEMU/patch.qemu-0.8.2_nptl-pb147082-mg1
and managed to apply it to the current code. It solves the TLS problem,
but now fails with a different error:
qemu: unhandled CPU exception 0x8 - aborting
R00=421a5c14 R01=00000000 R02=421a5c08 R03=00000001
R04=4008ef88 R05=00000000 R06=00000000 R07=00000000
R08=00000000 R09=00000000 R10=400a5000 R11=00000000
R12=ffff0fff R13=4007f858 R14=420b4b3c R15=ffff0fa0
PSR=20000010 --C- A usr32
...(registers in between are all zero)...
qemu: uncaught target signal 6 (Aborted) - exiting
This is exactly the same behaviour as shown by the Debian version of
qemu. Maybe they applied the same patch...
The problem does not show up if I use libraries from an old (2 years)
Timesys toolchain, so it seems to be triggered by code found in recent
libc versions.
What can I do now? Is this a known problem? Any patches for that?
Thanks,
Hans
