You ended up adding a comment for the above unpredictable instruction flagging
it as unpredictable.
There are thousands of other loads and stores you still need to flag as
unpredictable. What they all have in common is they have W=1 and P=0.
(bits #21 and #24) for addressing mode 3.
Please flag all loads and stores with the following format as unpredictable...
0xX02XXXXX
0xX03XXXXX
0xX06XXXXX
0xX07XXXXX
0xX0aXXXXX
0xX0bXXXXX
0xX0eXXXXX
..etc.
(Notice they all have bit 24 unset and bit 21 set.)
