+;; All extended shifts (shift by n+32) and variable shifts (32 and

+;; following conditions:
+;; 1) An integer multiply is currently executing
+;; 2) These types of shift instructions are executed immediately
+;; following an integer divide instruction.
+;; Workaround:
+;; 1) Make sure no integer multiply is running wihen these
+;; instruction are executed. If this cannot be predicted at
+;; compile time, then insert a "mfhi" to R0 instruction
+;; immediately after the integer multiply instruction. This
+;; will cause the integer multiply to complete before the shift

+;; 2) Separate integer divide and these two classes of shift
