--- Comment #3 from Wilco <wdijkstr at arm dot com> --- A simple workaround is to calculate cost1 early and only try the 2nd option if the cost is low (ie. it's not a huge expression that may evaluate into lots of ccmps). A slightly more advanced way would be to walk prep_seq_1 to count the actual number of ccmp instructions.
