Richi has asked the we break the wide-int patch so that the individual port and front end maintainers can review their parts without have to go through the entire patch.    This patch covers the scheduler code.

Ok?
* sched-vis.c
	(print_value): Handle CONST_WIDE_INT.
	* sel-sched-ir.c
	(lhs_and_rhs_separable_p): Update comment.
diff mbox
