	PR testsuite/60773
	* 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.
