As setup_frame() and setup_rt_frame() are already defined in linux-user/signal.c, this change should be enough. To test your change is not breaking anything, you can use the LTP: http://wiki.qemu.org/Testing/LTP > I have rebuilt the qemu version from unstable now (1:2.4+dfsg-4), > backported it to jessie and added TARGET_SH4 to the list of > architectures which has sigaltstack.

Can we merge this patch (see attached)? A good thing will be to post this to QEMU mailing list, but QEMU is in hard freeze phase for the moment. http://wiki.qemu.org/Planning/2.5 Laurent
