Hi, I was working on improving the results of scev, when VRP has broken the bootstrap, eliminating loops that were estimated as running a single time. These loop bound estimates come from the undefined behavior of accessing over the bounds of statically allocated data in genautomata.c:
Note this also happens in tree.h with tree_string and a couple more places. Really if it is the last element in a struct, you cannot say what the bounds are. Thanks, Andrew Pinski
