Subject: [PATCH v2 00/10] fix usage when killing loads & stores
Date: Tue, 13 Feb 2018 22:58:02 +0100	[thread overview]
Message-ID: <20180213215812.18735-1-luc.vanoostenryck@gmail.com> (raw)

This series contains 4 fixes for missing removal of
value or address usage when unneeded loads or stores
are killed during symbol simplification.

Change since v1:
- split patch "add helpers for pseudo's user-list's size" in two
  so to not add has_users() in a patch that where only the other
  helper is used (noticed by Linus).

This series is available in the Git repository at:
  https://github.com/lucvoo/sparse-dev/tree/fix-missing-kills-v2
  git://github.com/lucvoo/sparse-dev.git fix-missing-kills-v2

Luc Van Oostenryck (10):
      add testcase for bad killing of dominated stores
      add testcases for converted loads

      kill dead stores when simplifying symbols
      fix usage of deadborn loads
      add helper for pseudo's user-list's size
      add helper: has_users()
      use has_users() in dead_insn() too
      let kill_instruction() report if changes were made
