Or fix the code that assumes the ordering of the loops. Sorry for a bit missleading formulation -- the later solution does not avoid need for flushing the scev caches when the "linear" pass changes order of loops; the data are invalidated anyway. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18792
