From 34a856749fd5563c201e91ce1cd2dfc345f6f49c Mon Sep 17 00:00:00 2001 From: "Vikram S. Adve" Date: Fri, 25 Jul 2003 21:00:13 +0000 Subject: [PATCH] Remove unused field. Change the way unused regs. are marked and found to consider regType info (since multiple reg types may share the same reg class, e.g., single and double on Sparc). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7327 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/RegAlloc/PhyRegAlloc.h | 21 +++++++++++---------- lib/Target/SparcV9/RegAlloc/PhyRegAlloc.h | 21 +++++++++++---------- 2 files changed, 22 insertions(+), 20 deletions(-) diff --git a/lib/CodeGen/RegAlloc/PhyRegAlloc.h b/lib/CodeGen/RegAlloc/PhyRegAlloc.h index 731eef29c45..dc7772e4a23 100644 --- a/lib/CodeGen/RegAlloc/PhyRegAlloc.h +++ b/lib/CodeGen/RegAlloc/PhyRegAlloc.h @@ -71,8 +71,6 @@ class PhyRegAlloc : public NonCopyable { AddedInstrns AddedInstrAtEntry; // to store instrns added at entry LoopInfo *LoopDepthCalc; // to calculate loop depths - std::vector ResColList; // A set of reserved regs if desired. - // currently not used public: PhyRegAlloc(Function *F, const TargetMachine& TM, FunctionLiveVarInfo *Lvi, @@ -87,11 +85,11 @@ public: // access to register classes by class ID // const RegClass* getRegClassByID(unsigned int id) const { - return RegClassList[id]; + return RegClassList[id]; + } + RegClass* getRegClassByID(unsigned int id) { + return RegClassList[id]; } - RegClass* getRegClassByID(unsigned int id) { - return RegClassList[id]; } - private: void addInterference(const Value *Def, const ValueSet *LVSet, @@ -134,11 +132,14 @@ private: std::vector& MIBef, std::vector& MIAft); - int getUnusedUniRegAtMI(RegClass *RC, const MachineInstr *MInst, - const ValueSet *LVSetBef); + int getUnusedUniRegAtMI(RegClass *RC, const int RegType, + const MachineInstr *MInst, const ValueSet *LVSetBef); - void setRelRegsUsedByThisInst(RegClass *RC, const MachineInstr *MInst ); - int getUniRegNotUsedByThisInst(RegClass *RC, const MachineInstr *MInst); + void setRelRegsUsedByThisInst(RegClass *RC, const int RegType, + const MachineInstr *MInst ); + + int getUniRegNotUsedByThisInst(RegClass *RC, const int RegType, + const MachineInstr *MInst); void addInterf4PseudoInstr(const MachineInstr *MInst); }; diff --git a/lib/Target/SparcV9/RegAlloc/PhyRegAlloc.h b/lib/Target/SparcV9/RegAlloc/PhyRegAlloc.h index 731eef29c45..dc7772e4a23 100644 --- a/lib/Target/SparcV9/RegAlloc/PhyRegAlloc.h +++ b/lib/Target/SparcV9/RegAlloc/PhyRegAlloc.h @@ -71,8 +71,6 @@ class PhyRegAlloc : public NonCopyable { AddedInstrns AddedInstrAtEntry; // to store instrns added at entry LoopInfo *LoopDepthCalc; // to calculate loop depths - std::vector ResColList; // A set of reserved regs if desired. - // currently not used public: PhyRegAlloc(Function *F, const TargetMachine& TM, FunctionLiveVarInfo *Lvi, @@ -87,11 +85,11 @@ public: // access to register classes by class ID // const RegClass* getRegClassByID(unsigned int id) const { - return RegClassList[id]; + return RegClassList[id]; + } + RegClass* getRegClassByID(unsigned int id) { + return RegClassList[id]; } - RegClass* getRegClassByID(unsigned int id) { - return RegClassList[id]; } - private: void addInterference(const Value *Def, const ValueSet *LVSet, @@ -134,11 +132,14 @@ private: std::vector& MIBef, std::vector& MIAft); - int getUnusedUniRegAtMI(RegClass *RC, const MachineInstr *MInst, - const ValueSet *LVSetBef); + int getUnusedUniRegAtMI(RegClass *RC, const int RegType, + const MachineInstr *MInst, const ValueSet *LVSetBef); - void setRelRegsUsedByThisInst(RegClass *RC, const MachineInstr *MInst ); - int getUniRegNotUsedByThisInst(RegClass *RC, const MachineInstr *MInst); + void setRelRegsUsedByThisInst(RegClass *RC, const int RegType, + const MachineInstr *MInst ); + + int getUniRegNotUsedByThisInst(RegClass *RC, const int RegType, + const MachineInstr *MInst); void addInterf4PseudoInstr(const MachineInstr *MInst); };
