any news on this?
I reached
" disable versioning for alias - max number of generated checks exceeded."
because of PR49761 and really need to tell GCC to vectorize ignoring possibly
dependencies

--- Comment #14 from Tobias Burnus <burnus at gcc dot gnu.org> ---
With the comment of comment 13, C now supports:
#pragma GCC ivdep
as described at http://gcc.gnu.org/onlinedocs/gcc/Pragmas.html (link at the
bottom, [when the doc is updated in a couple of hours]).
Note: The C++ patch is still pending review; for Fortran, see also PR44646
comment 5.

------- Comment #9 from gjunk at sapience dot com 2007-09-19 21:34 -------
Thanks for feedback - not exactly sure where this leaves things - but if gcc
can deliver the same kind of floating point performance as icc it would be a
really good thing.
The 2005 article - wasn't clear to me what that meant other than this was
considered some time back - I assume this is a 2 step process.
(1) making the info available (perhaps that is already done - is that what
that means?)
(2) consuming the info so the optimization engine can do a better job -
which I suspect is work still remaining.
Thank you for all your help.
