From 22ff3eeebeb4d17749ab9d5cd4d5807f3066bb94 Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Wed, 6 Feb 2008 08:00:32 +0000 Subject: [PATCH] RegAllocaLocal still *requires* LiveVariables since it runs PHIElimination, followed by TwoAddress which requires LiveVariables. We cannot run LiveVariables on non-SSA code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46813 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/RegAllocLocal.cpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/lib/CodeGen/RegAllocLocal.cpp b/lib/CodeGen/RegAllocLocal.cpp index bdf7877a195..c933c51b3fc 100644 --- a/lib/CodeGen/RegAllocLocal.cpp +++ b/lib/CodeGen/RegAllocLocal.cpp @@ -14,11 +14,12 @@ #define DEBUG_TYPE "regalloc" #include "llvm/BasicBlock.h" -#include "llvm/CodeGen/Passes.h" +#include "llvm/CodeGen/LiveVariables.h" #include "llvm/CodeGen/MachineFunctionPass.h" #include "llvm/CodeGen/MachineInstr.h" #include "llvm/CodeGen/MachineFrameInfo.h" #include "llvm/CodeGen/MachineRegisterInfo.h" +#include "llvm/CodeGen/Passes.h" #include "llvm/CodeGen/RegAllocRegistry.h" #include "llvm/Target/TargetInstrInfo.h" #include "llvm/Target/TargetMachine.h" @@ -146,6 +147,7 @@ namespace { } virtual void getAnalysisUsage(AnalysisUsage &AU) const { + AU.addRequired(); AU.addRequiredID(PHIEliminationID); AU.addRequiredID(TwoAddressInstructionPassID); MachineFunctionPass::getAnalysisUsage(AU);
