Dear qemu-devs,<br><br>Two questions about what seems to be a deviation in the qemu-implementation from PowerPC specification:<br><br>1. In comparison operations (eg. PPC_OP(cmp)), why does qemu not set the SO bit (which will be the fourth bit) of T0? The spec says that the xer_so bit is copied into the fourth bit of the CRF register.
<br><br>2. In set_Rc0 operations (eg. PPC_OP(set_Rc0)), why is xer_ov used instead of xer_so? The spec says that a copy of xer_so is used.<br><br>I am using the powerpc manual as the specification document available here:
