on i686-linux (or x86_64-linux with -m32/-mno-sse).
The problem is that those tests use dg-options, which in */vect/
testsuite
throws away all the carefully added default options to enable
vectorization
on each target (and which e.g. vect_int etc. effective targets rely
on).
The old way would be to name those tests gcc.dg/vect/O3-pr101145*,
but we can also use dg-additional-options (which doesn't throw the
default
options, just appends to them) which is IMO better so that we don't
have to
rename the tests.
Tested on x86_64-linux and i686-linux, ok for trunk?

Hi Jakub,
Thanks for point out this!
Just find most of the cases in /vect/ are using dg-additional-options
instead dg-options.
