The reg-note lives in the RTL. ds_t is the same information represented
as a bitflag. E.g., see how the bits are accumulated in a ds_t variable
in ask_dependency_caches.

Hello,
I am a little confused by the code in sched-deps.c.
1. what is the purpose of the reg_note and ds_t? I see the function dk_to_ds,
and the comment in sched-int.h, "Dependence on instruction can be of multiple
types
(e.g. true and output). This fields enhance REG_NOTE_KIND informatio
