[PATCH] RS6000: Vectorize 32 bit int multiplication

Subject: [PATCH] RS6000: Vectorize 32 bit int multiplication

Adding this new pattern allows vectorizer to vectorize 32 bit int multiplications. Bootstrapped and tested on powerpc-darwin.

2005-04-15 Devang Patel <dpatel@apple.com>

* config/rs6000/atlivec.md (mulv4si3): New pattern.

* gcc.dg/vect/vect-11.c: Require effective target vect_int_mult. * gcc.dg/vect/vect-11a.c: New. * gcc.dg/vect/vect-none.c: Update. * lib/target-supports.exp (check_effective_target_vect_int_mult): New.

OK for mainline ?

Thanks
