That is unfortunate. Dorit did make a sincere effort to prepare her patches
long ago (mid February) well before leaving, and Victor has been constantly
pinging for reviews, ready to address them.

<rant> Maybe you can look at some of the regressions of the vectorizer first, instead of adding new features without first addressing regressions?

This could build up some trust that the newly added code will actually
be maintained
in the future.

For a quick bugzilla search, use the 4.2 regressions link on the
gcc.gnu.org page
and modify it to include "-ftree-vectorize" in the bug description.  I
count 3 P1 and
3 P2 regressions.
