From 2872177834d83b42cd042a37299cb7089965f36b Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Fri, 28 Nov 2008 00:58:15 +0000 Subject: [PATCH] remove some weirdness that came from the LSR code that has nothing to do with dead instruction elimination. No tests in dejagnu depend on this, so I don't know what it was needed for. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60202 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Utils/Local.cpp | 9 +-------- 1 file changed, 1 insertion(+), 8 deletions(-) diff --git a/lib/Transforms/Utils/Local.cpp b/lib/Transforms/Utils/Local.cpp index cab7f03ab0f..17ae9719011 100644 --- a/lib/Transforms/Utils/Local.cpp +++ b/lib/Transforms/Utils/Local.cpp @@ -190,14 +190,7 @@ void llvm::RecursivelyDeleteTriviallyDeadInstructions(Value *V, while (!Insts.empty()) { I = *Insts.begin(); Insts.erase(I); - - // If this is a PHI node, we may be able to make it dead if we know all the - // input values are the same. - if (PHINode *PN = dyn_cast(I)) { - if (Value *PNV = PN->hasConstantValue()) - PN->replaceAllUsesWith(PNV); - } - + // Okay, if the instruction is dead, delete it. if (!isInstructionTriviallyDead(I)) continue;
