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.

When comparing run time on some (floating point) CPU intensive code, we find
that Intel's ICC (9.1) compiler runs significantly faster (30 - 50%) for some
programs - this seems to stem (large) part from ICC's ability to take advantage
of #pragma ivdep. There may be some other differences of course. Tests were run
using gcc 3.3.3 - re-compiling relevant key code with gcc 4.1.2 did not make
any real change. 

Wondering if there are any plans to support this ?

thanks

------- 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.
