From 0cb80d9f0f71ff3faaf890bb9f023e53f4e8e3dc Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Sun, 13 Nov 2011 01:23:34 +0000 Subject: More dead code elimination in VirtRegMap. This thing is looking a lot like a virtual register map now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144486 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/VirtRegMap.cpp | 12 ------------ 1 file changed, 12 deletions(-) (limited to 'lib/CodeGen/VirtRegMap.cpp') diff --git a/lib/CodeGen/VirtRegMap.cpp b/lib/CodeGen/VirtRegMap.cpp index faa44ada3f..1a78db7107 100644 --- a/lib/CodeGen/VirtRegMap.cpp +++ b/lib/CodeGen/VirtRegMap.cpp @@ -19,7 +19,6 @@ #define DEBUG_TYPE "virtregmap" #include "VirtRegMap.h" #include "llvm/Function.h" -#include "llvm/CodeGen/LiveIntervalAnalysis.h" #include "llvm/CodeGen/MachineFrameInfo.h" #include "llvm/CodeGen/MachineFunction.h" #include "llvm/CodeGen/MachineInstrBuilder.h" @@ -32,12 +31,8 @@ #include "llvm/Support/Compiler.h" #include "llvm/Support/Debug.h" #include "llvm/Support/raw_ostream.h" -#include "llvm/ADT/BitVector.h" -#include "llvm/ADT/DenseMap.h" -#include "llvm/ADT/DepthFirstIterator.h" #include "llvm/ADT/Statistic.h" #include "llvm/ADT/STLExtras.h" -#include "llvm/ADT/SmallSet.h" #include using namespace llvm; @@ -62,14 +57,7 @@ bool VirtRegMap::runOnMachineFunction(MachineFunction &mf) { Virt2StackSlotMap.clear(); Virt2SplitMap.clear(); - allocatableRCRegs.clear(); - for (TargetRegisterInfo::regclass_iterator I = TRI->regclass_begin(), - E = TRI->regclass_end(); I != E; ++I) - allocatableRCRegs.insert(std::make_pair(*I, - TRI->getAllocatableSet(mf, *I))); - grow(); - return false; } -- cgit v1.2.3
