Loads/stores that are in the same BB as the load are not included in the Cand* sets at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19911 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Analysis/LoadValueNumbering.cpp | 10 ---------- 1 file changed, 10 deletions(-) diff --git a/lib/Analysis/LoadValueNumbering.cpp b/lib/Analysis/LoadValueNumbering.cpp index 354eb8d5602..5e91be2a840 100644 --- a/lib/Analysis/LoadValueNumbering.cpp +++ b/lib/Analysis/LoadValueNumbering.cpp @@ -374,17 +374,7 @@ void LoadVN::getEqualNumberNodes(Value *V, // Get dominators.
