Hi!While glibc fprintf allows printing %s with NULL argument as (null), other C libraries aren't that forgiving. If loc isn't UNKNOWN_LOCATION, but say BUILTINS_LOCATION, UNKNOWN_LOCATION with an associated BLOCK etc., we might ICE on those hosts. The patch also changes find_loop_location, so that it attempts to find a better location. Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk? 2013-01-22 Jakub Jelinek <ja...@redhat.com> PR middle-end/56074 * dumpfile.c (dump_loc): Only print loc if LOCATION_LOCUS (loc) isn't UNKNOWN_LOCATION nor BUILTINS_LOCATION. * tree-vect-loop-manip.c (find_loop_location): Also ignore stmt locations where LOCATION_LOCUS of the stmt location is UNKNOWN_LOCATION or BUILTINS_LOCATION.
OK. Jeff
