I don't really know much about qemu internals, but this is really
confusing me, sorry. Aren't env->fpu_status and env->cc_op two
elements of the same global state? Why it is OK to use one of
these fields to pass information to the next helper, but not the
other? I guess I must be missing something here ...
One of them has
cc_op = tcg_global_mem_new_i32(cpu_env, offsetof(CPUS390XState, cc_op),
"cc_op");
which makes it a TCG Global, which may not be modified at will, and one of them
does not.
