https://bugs.webkit.org/show_bug.cgi?id=121732 Reviewed by Geoffrey Garen. This is a refactoring change. Changed VirtualRegister from an enum to a class. Moved Operands::operandIsArgument(), operandToArgument(), argumentToOperand() and the similar functions for locals to VirtualRegister class. This is in preparation for changing the offset for the first local register from 0 to -1. This is needed since most native calling conventions have the architected frame pointer (e.g. %rbp for X86) point at the slot that stores the previous frame pointer. Local values start below that address. * bytecode/CodeBlock.cpp: * bytecode/CodeBlock.h: * bytecode/Instruction.h: * bytecode/LazyOperandValueProfile.h: * bytecode/MethodOfGettingAValueProfile.cpp: * bytecode/Operands.h: * bytecode/UnlinkedCodeBlock.cpp: * bytecode/UnlinkedCodeBlock.h: * bytecode/ValueRecovery.h: * bytecode/VirtualRegister.h: * bytecompiler/BytecodeGenerator.cpp: * bytecompiler/BytecodeGenerator.h: * bytecompiler/RegisterID.h: * debugger/DebuggerCallFrame.cpp: * dfg/DFGAbstractHeap.h: * dfg/DFGAbstractInterpreterInlines.h: * dfg/DFGArgumentPosition.h: * dfg/DFGArgumentsSimplificationPhase.cpp: * dfg/DFGByteCodeParser.cpp: * dfg/DFGCFGSimplificationPhase.cpp: * dfg/DFGCPSRethreadingPhase.cpp: * dfg/DFGCapabilities.cpp: * dfg/DFGConstantFoldingPhase.cpp: * dfg/DFGFlushLivenessAnalysisPhase.cpp: * dfg/DFGGraph.cpp: * dfg/DFGGraph.h: * dfg/DFGJITCode.cpp: * dfg/DFGNode.h: * dfg/DFGOSREntry.cpp: * dfg/DFGOSREntrypointCreationPhase.cpp: * dfg/DFGOSRExit.h: * dfg/DFGOSRExitCompiler32_64.cpp: * dfg/DFGOSRExitCompiler64.cpp: * dfg/DFGRegisterBank.h: * dfg/DFGScoreBoard.h: * dfg/DFGSpeculativeJIT.cpp: * dfg/DFGSpeculativeJIT.h: * dfg/DFGSpeculativeJIT64.cpp: * dfg/DFGValidate.cpp: * dfg/DFGValueRecoveryOverride.h: * dfg/DFGVariableAccessData.h: * dfg/DFGVariableEvent.h: * dfg/DFGVariableEventStream.cpp: * dfg/DFGVirtualRegisterAllocationPhase.cpp: * ftl/FTLExitArgumentForOperand.h: * ftl/FTLLink.cpp: * ftl/FTLLowerDFGToLLVM.cpp: * ftl/FTLOSREntry.cpp: * ftl/FTLOSRExit.cpp: * ftl/FTLOSRExit.h: * ftl/FTLOSRExitCompiler.cpp: * interpreter/CallFrame.h: * interpreter/Interpreter.cpp: * jit/AssemblyHelpers.h: * jit/JIT.h: * jit/JITCall.cpp: * jit/JITInlines.h: * jit/JITOpcodes.cpp: * jit/JITOpcodes32_64.cpp: * jit/JITStubs.cpp: * llint/LLIntSlowPaths.cpp: * profiler/ProfilerBytecodeSequence.cpp: * runtime/CommonSlowPaths.cpp: * runtime/JSActivation.cpp: git-svn-id: http://svn.webkit.org/repository/webkit/trunk@156474 268f45cc-cd09-0410-ab3c-d52691b4dbfc
