From fa1e73c447b61ba180cc85b78b53d78a6b63bbf6 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Thu, 24 Jun 2010 23:57:35 +0000 Subject: [PATCH] Make sure all eliminated kills are removed from VNInfo lists. This fixes PR7479 and PR7485. The test cases from those PRs are big, so not included. However, PR7485 comes from self hosting on FreeBSD, so we will surely hear about any regression. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106811 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/LiveInterval.cpp | 2 ++ 1 file changed, 2 insertions(+) diff --git a/lib/CodeGen/LiveInterval.cpp b/lib/CodeGen/LiveInterval.cpp index 7eb430db480..bf0bdd183c8 100644 --- a/lib/CodeGen/LiveInterval.cpp +++ b/lib/CodeGen/LiveInterval.cpp @@ -484,6 +484,8 @@ void LiveInterval::join(LiveInterval &Other, I->valno = NewVNInfo[OtherAssignments[RangeNo]]; assert(I->valno && "Adding a dead range?"); InsertPos = addRangeFrom(*I, InsertPos); + InsertPos->valno->removeKills(InsertPos->start, + InsertPos->end.getPrevSlot()); } ComputeJoinedWeight(Other);
