-;; This anonymous pattern and splitter wins because it reduces the latency
-;; of the shadd sequence without increasing the latency of the shift.
-;;
-;; We want to make sure and split up the operations for the scheduler since
-;; these instructions can (and should) schedule independently.
-;;
-;; It would be clearer if combine used the same operator for both expressions,
-;; it's somewhat confusing to have a mult in ine operation and an ashift
-;; in the other.
-;;
-;; If this pattern is not split before register allocation, then we must expose
-;; the fact that operand 4 is set before operands 1, 2 and 3 have been read.
