Does adding attribute aligned, as below, help?

Could you please attach slp-7.c's dump as well? I think it is a different
problem there.

------- Comment #7 from irar at il dot ibm dot com 2009-02-26 09:57 -------
In slp-7.c all the three loops get vectorized, including the loop that requires
vector multiplication for shorts. This patch
http://gcc.gnu.org/ml/gcc-patches/2008-07/msg00044.html added ARM to
vect_int_mult, but not to vect_short_mult, so I guess the fix should be:
Index: target-supports.exp

Does it make sense?

Patch fixes the failure of slp-7.c. I should note there is one XPASS
in the gcc.dg/vect testsuite:
XPASS: gcc.dg/vect/vect-iv-6.c scan-tree-dump-times vect "vectorized 1 loops" 1
