invoke.texi (-mveclibabi): Document new target option.
2007-08-30 Richard Guenther <rguenther@suse.de>
* doc/invoke.texi (-mveclibabi): Document new target option.
* config/i386/i386.opt (-mveclibabi): New target option.
* config/i386/i386.c (ix86_veclib_handler): Handler for
vectorization library support.
(override_options): Handle the -mveclibabi option, initialize
the vectorization library handler.
(ix86_builtin_vectorized_function): As fallback call the
vectorization library handler, if set.
(ix86_veclibabi_acml): New static function for ACML ABI style
vectorization support.
* gcc.target/i386/vectorize5.c: New testcase.
