When vect_multiple_sizes is true the number of times the pattern appears will be greater that normal. Most likely the pattern will appear once for each vector size. In the case of GCN, a pattern that normally appears 4 times now appears 24 times. The alternative would be to have a whole set of patterns for each configuration of each target that can have the multiple sizes. That or change the implementation of 'scan-tree-dump-times' to support expressions of some kind, but even then the expressions would get hairy. Andrew
