> Sebastian, can you please look at this? Sorry for having missed this bug. The problem here is that we end with two identical loops, as we copy almost all the statements in both loops. The attached patch solves the problem by counting the number of memory read and write operations per partition and compares it to the total number of memory operations in the Reduced Dependence Graph. Loop distribution is stopped when one of the partitions contains all the memory ops. Okay for trunk once it finishes regstrap?
