FAIL: gcc.dg/vect/vect-62.c scan-tree-dump-times not vectorized: redundant
loop. no profit to vectorize. 1
appeared on mainline on i686-pc-linux-gnu and ia64-hp-hpux11.23 (both -milp32
and -mlp64) between 20051118 (revision 107161) and 20051119 (revision 107213).
This test previously PASSed in revision 107161, FAILing in 107213. As the only
changes between 4.1 branching (107209) and 107213 are administrative changes as
part of the branching process, this regression presumably applies on 4.1 branch
as well.

Present on SPARC too.
Dorit, is it only a matter of changing the expected error message?

------- Comment #3 from dorit at il dot ibm dot com 2005-12-05 14:17 -------
> Dorit, is it only a matter of changing the expected error message?
Yes - the error message checks that the vectorizer detected that it's not worth
while to vectorize the loop because all operations in the loop are either dead
or only used outside the loop and can be moved out of the loop (e.g.
invariants, inductions). In other words - the loop should have been optimized
away by scalar optimizations. Indeed, this is what now happens - so the
specific loop that issued this message does not exist anymore. This dg line can
be removed from the test.
