--- Comment #5 from victork at il dot ibm dot com 2006-06-07 20:47 --- This happens because (vect_do_peeling_for_alignment) was designed in an assumption that latch is empty. Thus it doesn't handle PHIs in latches. (vect_analyze_loop_form) checks the latch is empty, but doesn't check that list of its PHIs is empty as too. -- victork at il dot ibm dot com changed: What|Removed |Added CC| |victork at il dot ibm dot | |com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26969
