> Another thing, 4.4 does not vectorize this loop anymore (and, therefore, there > is no ICE), because of unknown number of iterations: I also have remarked on one of the graphite testcases scop-matmult.c that we had a regression in the precision of the number of iterations from last graphite merge till yesterday's merge, i.e. from 138275 to 139870 We used to have a symbolic number of iterations, but now the result is scev_dont_know. I have not yet tracked this down to the patch that produced this regression. Sebastian -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36630
