[PATCH 0/3] kill dead loads

[Luc Van Oostenryck <luc.vanoostenryck@gmail.com>]

The goal of this series is to eliminate dead loads which,
especially the deadborn ones which, until now, weren't
removed.

This series is also available in the git repository at:
  git://github.com/lucvoo/sparse.git kill-dead-loads

Luc Van Oostenryck (3):
      extract has_users() from dead_insn()
      let kill_instruction() report if it made some changes or not
      kill dead loads
