Could help if you list specific functions that you expect to get vectorized. As far as dotprod is concerned - if it's operating on floats, you need to use -ffast-math or -funsafe-math-optimizations to enable vectorization. If it's dotprod of integers - probably the recent patches I sent to support reduction patterns (http://gcc.gnu.org/ml/gcc-patches/2005-12/msg01896.html) would be required (this functionality is present in auotvect; you can try to see if it's vectorized any better with autovect-branch). -- dorit at il dot ibm dot com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dorit at il dot ibm dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21468
