2021-06-30 Thread Ulrich Weigand
The FP-to-integer conversion instructions need to set CC 3 whenever a "special case" occurs; this is the case whenever the instruction also signals the IEEE invalid exception. (See e.g. figure 19-18 in the Principles of Operation.) However, qemu currently will set CC 3 only in the case where the
