Some of regressions are run-time failures. As of revision 137717,
there are still:
FAIL: Array_3 -O3 execution - source compiled test
FAIL: Array_3 -O3 -findirect-dispatch execution - source compiled test
FAIL: ext/pb_ds/regression/trie_data_map_rand.cc execution test
on both Linux/ia32 and Linux/x86-64.

For these two failures the output of -ftree-vectorizer-verbose=6 are similar.

------- Comment #14 from rguenth at gcc dot gnu dot org 2008-12-10 20:56 -------
Which is not vectorized because PRE doesn't move the invariant
D.2067_11 = a_9(D) == b_10(D);
out of the loop. If you make LIM do it (--param lim-expensive=1) the loop
is vectorized again.
I have a patch.
