+
+    Fix for the prefixed stq instruction in PC relative mode.
+    
+    The pstq instruction for R=1, was not using the correct effective address.
+    The EA_hi and EA_lo should have been based on the value of EA as calculated
+    by the function calculate_prefix_EA.  Unfortuanely, the EA_hi and EA_lo
+    addresses were still using the previous code (not PC relative) to calculate
+    the address from the contants of RA plus the offset.
