[Qemu-devel] [PATCH for-4.0 0/2] target/s390x: Implement STCK et al for CONFIG_USER_ONLY

Posted by Richard Henderson 5 years, 4 months ago

This is a non-privileged instruction that was only implemented
for system mode.  However, the stck instruction is used by glibc,
so this was causing SIGILL for programs run under debian stretch.
