(In reply to comment #23)
If I add to vect-42.c (with my patch) the line
/* { dg-final { scan-tree-dump-times "bla bla bla" 1 "vect" { target
vector_alignment_reachable } } } */
I get:

i.e., the test is done for -m32 (and fail) but not for -m64.
If I add the line
* { dg-final { scan-tree-dump-times "bla bla bla" 1 "vect" { target { !
vect_hw_misalign } } } } *//
I get

i.e., vect_hw_misalign is false for both -m32 and -m64.
So it looks that vect_hw_misalign has the opposite meaning of that assumed in
comment #16:
> hmmm... versioning should not be done for targets that support
> vect_hw_misalign...
Final note, the change in comment #17 does not help.
