--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #8) > How sparse is this bitmap will be? bitmap instead of sbitmap should be used > if the bitmap is going to be sparse. sbitmap is a fixed sized based on the > bitmap size while bitmap is better for sparse bitmaps as it is implemented > as linked list. Also it seems like DF already has def_in/def_out info, how much is duplicated information from there?
