From c72dcd103caea2fc887f4dd8edb693c7c5adac2f Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Mon, 23 Jun 2008 21:03:19 +0000 Subject: Instead of adding an isSS field to LiveInterval to denote stack slot. Use top bit of 'reg' instead. If the top bit is set, than the LiveInterval represents a stack slot live interval. llvm-svn: 52639 --- llvm/lib/CodeGen/StackSlotColoring.cpp | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'llvm/lib/CodeGen/StackSlotColoring.cpp') diff --git a/llvm/lib/CodeGen/StackSlotColoring.cpp b/llvm/lib/CodeGen/StackSlotColoring.cpp index 24bd028afda..b6a043c0dae 100644 --- a/llvm/lib/CodeGen/StackSlotColoring.cpp +++ b/llvm/lib/CodeGen/StackSlotColoring.cpp @@ -1,4 +1,4 @@ -//===-- StackSlotColoring.cpp - Sinking for machine instructions ----------===// +//===-- StackSlotColoring.cpp - Stack slot coloring pass. -----------------===// // // The LLVM Compiler Infrastructure // @@ -12,9 +12,9 @@ //===----------------------------------------------------------------------===// #define DEBUG_TYPE "stackcoloring" +#include "llvm/CodeGen/Passes.h" #include "llvm/CodeGen/LiveStackAnalysis.h" #include "llvm/CodeGen/MachineFrameInfo.h" -#include "llvm/CodeGen/Passes.h" #include "llvm/Support/CommandLine.h" #include "llvm/Support/Compiler.h" #include "llvm/Support/Debug.h" @@ -201,7 +201,6 @@ int StackSlotColoring::ColorSlot(LiveInterval *li) { bool StackSlotColoring::ColorSlots(MachineFunction &MF) { unsigned NumObjs = MFI->getObjectIndexEnd(); std::vector SlotMapping(NumObjs, -1); - SlotMapping.resize(NumObjs, -1); bool Changed = false; for (unsigned i = 0, e = SSIntervals.size(); i != e; ++i) { -- cgit v1.2.3
