* doc/sourcebuild.texi (vect_widen_mult_si_to_di_pattern): Add
documentation.
* lib/target-supports.exp:
(check_effective_target_vect_widen_si_to_di_pattern): New.
* gcc.dg/vect/pr60656.c: Require vect_long effective target.
Use scan-tree-dump-times for vect_widen_mult_si_to_di_pattern
targets only.
(foo): Fix up formatting.
(main): Call check_vect.
