Victor,

I hope you don't mind that I took the liberty and extended your patch to 
also include a synchronisation of various  testsuite/*/vect.exp 
target-dependent overrides and commit it to mainline by myself.

        PR testsuite/34168
        * lib/target-supports.exp (check_sse2_hw_available): New procedure.
        * gcc.dg/vect/vect.exp: Set dg-do-what-default to "compile"
        if SSE2 hardware is not available.
        * g++.dg/vect/vect.exp: Update target-dependent overrides to match
        gcc.dg/vect/vect.exp.
        * gfortran.dg/vect/vect.exp: Ditto.
        (check_effective_target_lp64_or_vect_no_align): Remove procedure.


The patch was regression tested on x86_64-pc-linux-gnu {,-m32} and was 
committed to mainline. I will commit similar patch to 4.3 tomorrow.

Thanks,
Uros.
