Still one TODO in doc/rtl.texi:
@findex LOG_LINKS
@item LOG_LINKS (@var{i})
A list (chain of @code{insn_list} expressions) giving information about
dependencies between instructions within a basic block. Neither a jump
nor a label may come between the related insns. These are only used by
the schedulers and by combine. This is a deprecated data structure.
Def-use and use-def chains are now preferred.
Ciao!
