The API specifies that convertToType may opt not to handle a conversion: "@result The objects's converted value, or NULL if the object was not converted." In which case, it would propagate first up the JSClass hierarchy, calling its superclass's conversion functions, and failing that call the JSObject::defaultValue function. Unfortunately this behaviour was removed in bug#69677/bug#69858, and instead we now rely on the toStringCallback/valueOfCallback function introduced in bug#69156. Even after a fix in bug#73368, these will return the result from the first convertToType they find, regardless of whether this result is null, and if no convertToType method is found in the api class hierarchy (possible if toStringCallback/valueOfCallback was accessed off the prototype chain), they will also return a null pointer. This is unsafe. It would be easy to make the approach based around toStringCallback/valueOfCallback continue to walk the api class hierarchy, but making the fallback to defaultValue would be problematic (since defaultValue calls toStringCallback/valueOfCallback, this would infinitely recurse). Making the fallback work with toString/valueOf methods attached to api objects is probably not the right thing to do – instead, we should just implement the defaultValue trap for api objects. In addition, this bug highlights that fact that JSCallbackFunction::call will allow a hard null to be returned from C to JavaScript - this is not okay.

The old JIT expects that the result of the last operation is in the lastResultRegister. The DFG JIT is designed to correctly track the lastResultRegister by looking at SetLocal nodes. However, when the DFG JIT inlines a code block, it forgets that the inlined code block's result would have been placed in the lastResultRegister. Hence if we OSR exit on the first node following the end of an inlined code block that had a return value, and that first node uses the return value, the old JIT will get massively confused. This patch takes a surgical approach: instead of making the DFG smarter, it makes the old JIT slightly dumber. * jit/JITCall.cpp: (JSC::JIT::emit_op_call_put_result): 2011-01-27 Lucas Forschler Merge 106067 2012-01-26 Filip Pizlo All DFG helpers that may call out to arbitrary JS code must know where they were called from due to inlining and call stack walking https://bugs.webkit.org/show_bug.cgi?id=77070 Reviewed by Geoff Garen. Changed the DFG to always record a code origin index in the tag of the argument count (which we previously left blank for the benefit of LLInt, but is still otherwise unused by the DFG), so that if we ever need to walk the stack accurately we know where to start. In particular, if the current ExecState* points several semantic call frames away from the true semantic call frame because we had performed inlining, having the code origin index recorded means that we can reify those call frames as necessary to give runtime/library code an accurate view of the current JS state. This required several large but mechanical changes: - Calling a function from the DFG now plants a store32 instruction to store the code origin index. But the indices of code origins were previously picked by the DFG::JITCompiler after code generation completed. I changed this somewhat; even though the code origins are put into the CodeBlock after code gen, the code gen now knows a priori what their indices will be. Extensive assertions are in place to ensure that the two don't get out of sync, in the form of the DFG::CallBeginToken. Note that this mechanism has almost no effect on JS calls; those don't need the code origin index set in the call frame because we can get it by doing a binary search on the return PC. - Stack walking now always calls trueCallFrame() first before beginning the walk, since even the top call frame may be wrong. It still calls trueCallerFrame() as before to get to the next frame, though trueCallerFrame() is now mostly a wrapper around callerFrame()->trueCallFrame(). - Because the mechanism for getting the code origin of a call frame is bimodal (either the call frame knows its code origin because the code origin index was set, or it's necessary to use the callee frame's return PC), I put in extra mechanisms to determine whether your caller, or your callee, corresponds to a call out of C++ code. Previously we just had the host call flag, but this is insufficient as it does not cover the case of someone calling JSC::call(). But luckily we can determine this just by looking at the return PC: if the return PC is in range of the ctiTrampiline, then two things are true: this call frame's PC will tell you nothing about where you came from in your caller, and the caller already knows where it's at because it must have set the code origin index (unless it's not DFG code, in which case we don't care because there is no inlining to worry about). - During testing this revealed a simple off-by-one goof in DFG::ByteCodeParser's inlining code, so I fixed it. - Finally because I was tired of doing random #if's for checking if I should be passing around an Instruction* or a ReturnAddressPtr, I created a class called AbstractPC that holds whatever notion of a PC is appropriate for the current execution environment. It's designed to work gracefully even if both the interpreter and the JIT are compiled in, and should integrate nicely with the LLInt.

Added the ability to cache JS getter calls and custom getter calls in the DFG. Most of this is pretty mundane, since the old JIT supported this functionality as well. But a couple interesting things had to happen: - There are now two variants of GetById: GetById, which works as before, and GetByIdFlush, which flushes registers prior to doing the GetById. Only GetByIdFlush can be used for caching getters. We detect which GetById style to use by looking at the inline caches of the old JIT. - Exception handling for getter calls planted in stubs uses a separate lookup handler routine, which uses the CodeOrigin stored in the StructureStubInfo.

Added assertions that at the end of a successfully generated basic block, all use counts should be zero. This revealed a number of bugs: - Array length optimizations were turning a must-generate node into one that is not must-generate, but failing to change the ref count accordingly. - Indexed property storage optimizations were failing to deref their children, or to deref the indexed property storage node itself. Also, they used the Phantom node as a replacement. But the Phantom node is must-generate, which was causing bizarre issues. So this introduces a Nop node, which should be used in cases where you want a node that is skipped and has no children. This does not have any significant performance effect, but it should relieve some register pressure. The main thing this patch adds, though, are the assertions, which should make it easier to do register allocation related changes in the future. * dfg/DFGAbstractState.cpp: (JSC::DFG::AbstractState::execute): * dfg/DFGGenerationInfo.h: (JSC::DFG::GenerationInfo::initConstant): (JSC::DFG::GenerationInfo::initInteger): (JSC::DFG::GenerationInfo::initJSValue): (JSC::DFG::GenerationInfo::initCell): (JSC::DFG::GenerationInfo::initBoolean): (JSC::DFG::GenerationInfo::initDouble): (JSC::DFG::GenerationInfo::initStorage): (JSC::DFG::GenerationInfo::use): * dfg/DFGGraph.h: (JSC::DFG::Graph::clearAndDerefChild1): (JSC::DFG::Graph::clearAndDerefChild2): (JSC::DFG::Graph::clearAndDerefChild3): * dfg/DFGNode.h: (JSC::DFG::Node::deref): * dfg/DFGPropagator.cpp: (JSC::DFG::Propagator::propagateNodePredictions): (JSC::DFG::Propagator::fixupNode): * dfg/DFGSpeculativeJIT.cpp: (JSC::DFG::SpeculativeJIT::compile): * dfg/DFGSpeculativeJIT32_64.cpp: (JSC::DFG::SpeculativeJIT::compile): * dfg/DFGSpeculativeJIT64.cpp: (JSC::DFG::SpeculativeJIT::compile): 2011-12-22 Oliver Hunt Merge 103127 2011-12-16 Filip Pizlo DFG OSR exit may get confused about where in the scratch buffer it stored a value https://bugs.webkit.org/show_bug.cgi?id=74695 Reviewed by Oliver Hunt.

We need to be careful about how we look for the baseline CodeBlock if we're lazy-compiling an OSR exit after our CodeBlock has been jettisoned. In short, use CodeBlock::baselineVersion() instead of CodeBlock::alternative(). No performance effect. No tests because all of our heuristics work very hard to make sure that this never happens in the first place. OSR exits are rare by design, and jettisoning of CodeBlocks (i.e. recompilation) is even rarer. Furthermore, OSR exits after a CodeBlock has been jettisoned is rarer still because the whole point of jettisoning is to bring the probability of future OSR exits to as close to zero as possible. But even that isn't enough to trigger this bug; it requires the OSR exit after a jettison to be the first of its kind; our whole design tries to ensure that CodeBlocks tend to OSR exit at a handful (i.e. 1 in most cases) of points, and since jettisoning is triggered by OSR, in most sane cases the OSR exits after jettison will not require lazy OSR compilation. So this is a truly evil case, and any test for it would be quite fragile. * bytecode/CodeBlock.h: (JSC::CodeBlock::specializationKind): (JSC::CodeBlock::largeFailCountThreshold): (JSC::CodeBlock::largeFailCountThresholdForLoop): * dfg/DFGAssemblyHelpers.h: (JSC::DFG::AssemblyHelpers::AssemblyHelpers): (JSC::DFG::AssemblyHelpers::baselineCodeBlockFor): (JSC::DFG::AssemblyHelpers::baselineCodeBlock): * dfg/DFGDriver.cpp: (JSC::DFG::compile): * dfg/DFGOSRExitCompiler.cpp: * dfg/DFGOSRExitCompiler64.cpp: (JSC::DFG::OSRExitCompiler::compileExit): 2011-11-18 Oliver Hunt Merge r100219 2011-11-14 Filip Pizlo DFG put_by_id transition optimizations test the wrong structures https://bugs.webkit.org/show_bug.cgi?id=72324 Reviewed by Gavin Barraclough. * dfg/DFGByteCodeParser.cpp: (JSC::DFG::ByteCodeParser::structureChainIsStillValid): (JSC::DFG::ByteCodeParser::parseBlock): * jit/JITPropertyAccess.cpp: (JSC::JIT::privateCompilePutByIdTransition): 2011-11-18 Oliver Hunt Merge r100197 2011-11-14 Mark Rowe testRegExp should not be installed as part of JavaScriptCore testRegExp and testapi.js were being installed in the JavaScriptCore framework.

We can simplify things by moving to a common mechanism whereby all forwards matching code is generated in one pass, and all backtracking code is generated in another. Backtracking code can be generated in reverse order, to optimized the common fall-through case. To make it easier to walk over the pattern, we can first convert to a more byte-code like format before JIT generating.

We want to clear polymorphic caches, since they can keep alive large object graphs that have gone "stale". For the same reason, but to a lesser extent, we also want to clear linked functions and other one-off caches. This has the side-benefit of reducing memory footprint from run-once functions, and of allowing predictions and caches that have failed to re-specialize.

String operator+ reallocates unnecessarily when concatting > 2 strings https://bugs.webkit.org/show_bug.cgi?id=58420 Provide a faster String append operator. Up until now, "String operator+(const String& a, const String& b)" copied String a into a temporary object, and used a.append(b), which reallocates a new buffer of aLength+bLength. When concatting N strings using operator+, this leads to N-1 reallocations. Replace this with a flexible operator+ implementation, that avoids these reallocations. When concatting a 'String' with any string type (char*, UChar, Vector, String, AtomicString, etc..) a StringAppend object is created, which holds the intermediate string objects, and delays creation of the final string, until operator String() is invoked. template StringAppend operator+(const String& string1, T string2) { return StringAppend(string1, string2); } template StringAppend > operator+(U string1, const StringAppend& string2) { return StringAppend >(string1, string2); } When concatting three strings - "String a, b, c; String result = a + b + c;" following happens: first a StringAppend object is created by operator+(const String& string1, String string2). Then operator+(String string1, const StringAppend& string2) is invoked, which returns a StringAppend > object. Then operator String() is invoked, which allocates a StringImpl object, once, large enough to hold the final string - it uses tryMakeString provided by StringConcatenate.h under the hoods, which guards us against too big string allocations, etc. Note that the second template, defines a recursive way to concat an arbitary number of strings into a single String with just one allocation. * GNUmakefile.list.am: Add StringOperators.h to build. * JavaScriptCore.exp: Export WTF::emptyString().

The patch introduces a new macro ASSERT_JIT_OFFSET_UNUSED and ASSERT_WITH_MESSAGE_UNUSED which copy the idea of ASSERT_UNUSED. * jit/JIT.h: * jit/JITPropertyAccess.cpp: (JSC::JIT::emit_op_method_check): (JSC::JIT::compileGetByIdHotPath): (JSC::JIT::emit_op_put_by_id): * wtf/Assertions.h: (assertWithMessageUnused): 2011-04-29 Jer Noble Reviewed by Eric Seidel.

The JmpSrc/JmpDst classes predate the MacroAssembler interface. Having these object be per-assembler in unhelpful, causes unnecessary code duplication, and prevents the AssemblerBuffer from providing a richer type for labels. The limited semantic meaning that they did convey is undermined by the manner in which their meanings have been overloaded (use of JmpSrc for Call, JmpDst for data labels). Jumps on ARMv7 have had additional information added to the object via the ARMv7 JmpSrc. This data should probably be in the instruction stream. This patch does not fix the problem, and moves the data (ifdefed) to AbstractMacroAssembler::Jump (which is effectively where it was before!). This at least closes the hole such that no further data may be added to JmpSrc, but this is unfortunate, and should be cleaned up. * assembler/ARMAssembler.h: (JSC::ARMAssembler::blx): (JSC::ARMAssembler::label): (JSC::ARMAssembler::align): (JSC::ARMAssembler::loadBranchTarget): (JSC::ARMAssembler::jmp): (JSC::ARMAssembler::linkPointer): (JSC::ARMAssembler::linkJump): (JSC::ARMAssembler::linkCall): (JSC::ARMAssembler::getRelocatedAddress): (JSC::ARMAssembler::getDifferenceBetweenLabels): (JSC::ARMAssembler::getCallReturnOffset): * assembler/ARMv7Assembler.h: (JSC::ARMv7Assembler::b): (JSC::ARMv7Assembler::blx): (JSC::ARMv7Assembler::bx): (JSC::ARMv7Assembler::label): (JSC::ARMv7Assembler::align): (JSC::ARMv7Assembler::getRelocatedAddress): (JSC::ARMv7Assembler::getDifferenceBetweenLabels): (JSC::ARMv7Assembler::getCallReturnOffset): (JSC::ARMv7Assembler::linkJump): (JSC::ARMv7Assembler::linkCall): (JSC::ARMv7Assembler::linkPointer): * assembler/AbstractMacroAssembler.h: (JSC::AbstractMacroAssembler::Label::isSet): (JSC::AbstractMacroAssembler::Call::Call): (JSC::AbstractMacroAssembler::Jump::Jump): (JSC::AbstractMacroAssembler::Jump::link): (JSC::AbstractMacroAssembler::Jump::linkTo): (JSC::AbstractMacroAssembler::linkPointer): (JSC::AbstractMacroAssembler::getLinkerAddress): * assembler/AssemblerBuffer.h: (JSC::AssemblerLabel::AssemblerLabel): (JSC::AssemblerLabel::isSet): * assembler/LinkBuffer.h: (JSC::LinkBuffer::patch): * assembler/MIPSAssembler.h: (JSC::MIPSAssembler::label): (JSC::MIPSAssembler::align): (JSC::MIPSAssembler::getRelocatedAddress): (JSC::MIPSAssembler::getDifferenceBetweenLabels): (JSC::MIPSAssembler::getCallReturnOffset): (JSC::MIPSAssembler::linkJump): (JSC::MIPSAssembler::linkCall): (JSC::MIPSAssembler::linkPointer): * assembler/MacroAssemblerARMv7.h: (JSC::MacroAssemblerARMv7::branchDouble): (JSC::MacroAssemblerARMv7::branchDoubleZeroOrNaN): (JSC::MacroAssemblerARMv7::jump): (JSC::MacroAssemblerARMv7::nearCall): (JSC::MacroAssemblerARMv7::call): (JSC::MacroAssemblerARMv7::ret): (JSC::MacroAssemblerARMv7::tailRecursiveCall): (JSC::MacroAssemblerARMv7::makeBranch): * assembler/MacroAssemblerMIPS.h: (JSC::MacroAssemblerMIPS::nearCall): (JSC::MacroAssemblerMIPS::call): (JSC::MacroAssemblerMIPS::tailRecursiveCall): (JSC::MacroAssemblerMIPS::branchTrue): (JSC::MacroAssemblerMIPS::branchFalse): (JSC::MacroAssemblerMIPS::branchEqual): (JSC::MacroAssemblerMIPS::branchNotEqual): * assembler/SH4Assembler.h: (JSC::SH4Assembler::call): (JSC::SH4Assembler::jmp): (JSC::SH4Assembler::jne): (JSC::SH4Assembler::je): (JSC::SH4Assembler::label): (JSC::SH4Assembler::align): (JSC::SH4Assembler::linkJump): (JSC::SH4Assembler::linkCall): (JSC::SH4Assembler::linkPointer): (JSC::SH4Assembler::getCallReturnOffset): (JSC::SH4Assembler::getRelocatedAddress): (JSC::SH4Assembler::getDifferenceBetweenLabels): (JSC::SH4Assembler::patchPointer): * assembler/X86Assembler.h: (JSC::X86Assembler::call): (JSC::X86Assembler::jmp): (JSC::X86Assembler::jmp_r): (JSC::X86Assembler::jne): (JSC::X86Assembler::jnz): (JSC::X86Assembler::je): (JSC::X86Assembler::jz): (JSC::X86Assembler::jl): (JSC::X86Assembler::jb): (JSC::X86Assembler::jle): (JSC::X86Assembler::jbe): (JSC::X86Assembler::jge): (JSC::X86Assembler::jg): (JSC::X86Assembler::ja): (JSC::X86Assembler::jae): (JSC::X86Assembler::jo): (JSC::X86Assembler::jp): (JSC::X86Assembler::js): (JSC::X86Assembler::jCC): (JSC::X86Assembler::label): (JSC::X86Assembler::labelFor): (JSC::X86Assembler::align): (JSC::X86Assembler::linkJump): (JSC::X86Assembler::linkCall): (JSC::X86Assembler::linkPointer): (JSC::X86Assembler::getCallReturnOffset): (JSC::X86Assembler::getRelocatedAddress): (JSC::X86Assembler::getDifferenceBetweenLabels): (JSC::X86Assembler::rewindToLabel): (JSC::X86Assembler::X86InstructionFormatter::immediateRel32): (JSC::X86Assembler::X86InstructionFormatter::rewindToLabel): * jit/JIT.cpp: (JSC::JIT::privateCompileMainPass): * jit/JIT.h: * jit/JITInlineMethods.h: (JSC::JIT::atJumpTarget): (JSC::JIT::emitGetVirtualRegister): * jit/JITOpcodes.cpp: (JSC::JIT::emit_op_jmp): (JSC::JIT::emit_op_jfalse): (JSC::JIT::emit_op_jeq_null): (JSC::JIT::emit_op_jneq_null): (JSC::JIT::emit_op_jneq_ptr): (JSC::JIT::emit_op_jsr): (JSC::JIT::emit_op_jtrue): (JSC::JIT::emit_op_jmp_scopes): 2011-05-01 Chao-ying Fu Reviewed by Eric Seidel.

If a var or argument is used as the base for a GetByVal or PutByVal access we are speculating that it is of type Array (we only generate code on the speculative path to perform array accesses). By typing the var or args slot as Array, and checking on entry to the function (in the case of args), and each time the local is written to, we can avoid a type check at each point the array is accessed. This will typically hoist type checks out of loops. Similarly, any local that is incremented or decremented, or is the input or output or a bitwise operator, is likely to be an integer. By typing the local as int32 we can avoid speculation checks on access, and tagging when writing to the slot. All accesses can become 32bit instead of 64. * dfg/DFGByteCodeParser.cpp: (JSC::DFG::ByteCodeParser::set): (JSC::DFG::ByteCodeParser::predictArray): (JSC::DFG::ByteCodeParser::predictInt32): (JSC::DFG::ByteCodeParser::parseBlock): * dfg/DFGGraph.h: (JSC::DFG::PredictionSlot::PredictionSlot): (JSC::DFG::Graph::Graph): (JSC::DFG::Graph::predict): (JSC::DFG::Graph::getPrediction): * dfg/DFGJITCompiler.cpp: (JSC::DFG::JITCompiler::compileFunction): * dfg/DFGJITCompiler.h: (JSC::DFG::JITCompiler::tagFor): (JSC::DFG::JITCompiler::payloadFor): * dfg/DFGNode.h: * dfg/DFGNonSpeculativeJIT.cpp: (JSC::DFG::NonSpeculativeJIT::compile): * dfg/DFGSpeculativeJIT.cpp: (JSC::DFG::SpeculativeJIT::compile): (JSC::DFG::SpeculativeJIT::checkArgumentTypes): (JSC::DFG::SpeculativeJIT::initializeVariableTypes): * dfg/DFGSpeculativeJIT.h: * runtime/Executable.cpp: (JSC::tryDFGCompile): 2011-04-25 David Levin Reviewed by James Robinson.

This process is iterative, inserting new phis into predecessors as necessary. * dfg/DFGByteCodeParser.cpp: (JSC::DFG::ByteCodeParser::getVariable): (JSC::DFG::ByteCodeParser::setVariable): (JSC::DFG::ByteCodeParser::getArgument): (JSC::DFG::ByteCodeParser::setArgument): (JSC::DFG::ByteCodeParser::parseBlock): (JSC::DFG::ByteCodeParser::processWorkQueue): (JSC::DFG::ByteCodeParser::allocateVirtualRegisters): (JSC::DFG::ByteCodeParser::parse): * dfg/DFGGraph.cpp: (JSC::DFG::Graph::dump): (JSC::DFG::Graph::refChildren): * dfg/DFGGraph.h: (JSC::DFG::Graph::ref): * dfg/DFGNode.h: (JSC::DFG::Node::ref): * dfg/DFGNonSpeculativeJIT.cpp: (JSC::DFG::NonSpeculativeJIT::compile): * dfg/DFGScoreBoard.h: (JSC::DFG::ScoreBoard::~ScoreBoard): (JSC::DFG::ScoreBoard::dump): * dfg/DFGSpeculativeJIT.cpp: (JSC::DFG::SpeculativeJIT::compile): 2011-04-22 Vitaly Repeshko Reviewed by Adam Barth.

Off by one initialising repeat callframe https://bugs.webkit.org/show_bug.cgi?id=58838 If the end of a callframe made for a repeat call landed on a page boundary the following page may not have been committed which means that the off by one could lead to a crash. However it could only happen in this case and only on windows which is why it was so hard to repro. Alas given the steps needed to reproduce are such that it's not really possible to make a testcase.

Bug 58620 - DFG JIT - loading of arguments should not be lazy This optimization is overly simplistic. It only works because we never write out definitions to arguments (since we currently only compile single block functions).

Bug 58600 - DFG JIT bugs in ValueToInt, PutByVal The bug in PutByVal is that an operand is in JSValueOperand - when this locks an integer into a register it will always retag the value without checking if the register is already locked. This is a problem where the value being stored by a PutByVal is the same as the subscript. The subscript is locked into a register first, as a strict integer. Locking the value results in the subscript being modified. The bug in ValueToInt related to the function of sillentFillAllRegisters. The problem is that this method will restore all register values from prior to the call, overwriting the result of the call out. Allow a register to be passed to specifically be excluded from being preserved. * assembler/ARMAssembler.h: (JSC::ARMAssembler::debugOffset): * assembler/ARMv7Assembler.h: (JSC::ARMv7Assembler::ARMInstructionFormatter::debugOffset): * assembler/AbstractMacroAssembler.h: (JSC::AbstractMacroAssembler::debugOffset): * assembler/AssemblerBuffer.h: (JSC::AssemblerBuffer::debugOffset): * assembler/LinkBuffer.h: (JSC::LinkBuffer::debugAddress): * assembler/MIPSAssembler.h: (JSC::MIPSAssembler::debugOffset): * assembler/MacroAssemblerX86_64.h: (JSC::MacroAssemblerX86_64::orPtr): * assembler/X86Assembler.h: (JSC::X86Assembler::debugOffset): (JSC::X86Assembler::X86InstructionFormatter::debugOffset): * dfg/DFGByteCodeParser.cpp: (JSC::DFG::ByteCodeParser::parse): * dfg/DFGGenerationInfo.h: * dfg/DFGJITCodeGenerator.cpp: (JSC::DFG::JITCodeGenerator::fillJSValue): * dfg/DFGJITCodeGenerator.h: (JSC::DFG::JITCodeGenerator::isConstant): * dfg/DFGJITCompiler.cpp: (JSC::DFG::JITCompiler::compileFunction): * dfg/DFGJITCompiler.h: (JSC::DFG::JITCompiler::isConstant): * dfg/DFGNonSpeculativeJIT.cpp: (JSC::DFG::NonSpeculativeJIT::valueToNumber): (JSC::DFG::NonSpeculativeJIT::valueToInt32): (JSC::DFG::NonSpeculativeJIT::numberToInt32): (JSC::DFG::NonSpeculativeJIT::isKnownInteger): (JSC::DFG::NonSpeculativeJIT::isKnownNumeric): (JSC::DFG::NonSpeculativeJIT::compile): * dfg/DFGNonSpeculativeJIT.h: (JSC::DFG::NonSpeculativeJIT::silentSpillGPR): (JSC::DFG::NonSpeculativeJIT::silentSpillFPR): (JSC::DFG::NonSpeculativeJIT::silentFillGPR): (JSC::DFG::NonSpeculativeJIT::silentFillFPR): (JSC::DFG::NonSpeculativeJIT::silentSpillAllRegisters): (JSC::DFG::NonSpeculativeJIT::silentFillAllRegisters): * dfg/DFGSpeculativeJIT.cpp: (JSC::DFG::SpeculativeJIT::compile): 2011-04-14 Geoffrey Garen Reviewed by Oliver Hunt.

After this patch, the GYP build can build JavaScriptCore without help from the main normal build system. * JavaScriptCore.gypi: * gyp/JavaScriptCore.gyp: * gyp/generate-derived-sources.sh: * gyp/generate-dtrace-header.sh: 2011-03-22 Jay Civelli Reviewed by David Levin.

Bug 56284 - Add a dataflow intermediate representation for use in JIT generation. The JSC JIT presently generates code directly from the bytecode used by the interpreter. This is not an optimal intermediate representation for JIT code generation, since it does not capture liveness information of values, and provides little opportunity to perform any static analysis for even primitive types. The JIT currently generates two code paths, a fast path handling common cases, and a slower path handling less common operand types. However the slow path jumps back into the fast path, meaning that information arising from the earlier type checks cannot be propagated to later operations. This patch adds: * a dataflow intermediate representation capable of describing a single basic block of operations, * a mechanism to convert a simple, single-block bytecode functions to the new IR, * and a JIT code generator capable of generating code from this representation. The JIT generates two code paths, with the slower path not reentering the fast path mid-block, allowing speculative optimizations to be made on the hot path, with type information arising from these speculative decisions able to be propagated through the dataflow. Code generation of both speculative and non-speculative paths exploits the type and liveness information represented in the dataflow graph to attempt to avoid redundant boxing and type-checking of values, and to remove unnecessary spills of temporary values to the RegisterFile. The dataflow JIT currently can only support a subset of bytecode operations, limited to arithmetic, bit-ops, and basic property access. Functions that cannot be compiled by the dataflow JIT will be run using the existing JIT. The coverage of the dataflow JIT will be expanded to include, control-flow, function calls, and then the long-tail of remaining bytecode instructions. The JIT presently only support JSVALUE64, and as a consequence of this only supports x86-64. The status of the dataflow JIT is currently work-in-progress. Limitations of the present JIT code generation may cause performance regressions, particularly: * the policy to only generate arithmetic code on the speculative path using integer instructions, never using floating point. * the policy to only generate arithmetic code on the non-speculative path using floating point instructions, never using integer. * always generating JSValue adds on the non-speculative path as a call out to a C-function, never handling this in JIT code. * always assuming by-Value property accesses on the speculative path to be array accesses. * generating all by-Value property accesses from the non-speculative path as a call out to a C-function. * generating all by-Indentifer property accesses as a call out to a C-function. Due to these regressions, the code is landed in a state where it is disabled in most cases by the ENABLE_DFG_JIT_RESTRICTIONS guard in Platform.h.

Remove "register slot" concept from PropertySlot https://bugs.webkit.org/show_bug.cgi?id=55621 PropertySlot had already stopped storing Register "slots" so this patch is simply removing that api entirely. This exposed a problem in the ProgramNode constructor for BytecodeGenerator where it reads from the registerfile before it has initialised it. This bug wasn't a problem before as we were merely testing for property existence rather than the actual value, and used to work because setRegisterSlot didn't check that the provided slot contained an initialised value.

Make WeakGCMap use new handle infrastructure https://bugs.webkit.org/show_bug.cgi?id=55100 Remove old WeakGCMap implementation and move over to new handle based logic. This has a number of benefits, most notably it makes a WeakGCMap always reflect the true state of the world by as all entries are removed at the first gc cycle that makes them dead. This allows us to get rid of code in a wide variety of objects where the only purpose was to remove themselves from maps. It also means that we no longer need to have special "unchecked" versions of any functions on WeakGCMap. Alas in order to maintain compatibility with the JSWeakObjectMapClear API it is still necessary to have an api that resembles uncheckedRemove, this is now deprecatedRemove and will be dealt with in a later patch. In order to get correct semantics in WeakGCMap we need more contextual information in the finalizer, so we've added an abstract class based finaliser and a context parameter to the calls. The new an improved WeakGCMap also results in sigificantly more churn in the weak handle lists so exposed some potential problems during the post mark phase which have been rectified as well. * API/JSWeakObjectMapRefPrivate.cpp: * API/JSWeakObjectMapRefPrivate.h: * runtime/Heap.cpp: (JSC::Heap::globalObjectCount): (JSC::Heap::protectedGlobalObjectCount): * runtime/JSGlobalData.cpp: (JSC::JSGlobalData::JSGlobalData): * runtime/JSGlobalData.h: * runtime/JSGlobalObject.cpp: (JSC::JSGlobalObject::~JSGlobalObject): (JSC::JSGlobalObject::init): * runtime/WeakGCMap.h: (JSC::WeakGCMap::iterator::iterator): (JSC::WeakGCMap::iterator::get): (JSC::WeakGCMap::iterator::getSlot): (JSC::WeakGCMap::iterator::operator++): (JSC::WeakGCMap::iterator::operator==): (JSC::WeakGCMap::iterator::operator!=): (JSC::WeakGCMap::WeakGCMap): (JSC::WeakGCMap::isEmpty): (JSC::WeakGCMap::clear): (JSC::WeakGCMap::get): (JSC::WeakGCMap::getSlot): (JSC::WeakGCMap::set): (JSC::WeakGCMap::take): (JSC::WeakGCMap::size): (JSC::WeakGCMap::deprecatedRemove): (JSC::WeakGCMap::begin): (JSC::WeakGCMap::end): (JSC::WeakGCMap::~WeakGCMap): (JSC::WeakGCMap::finalize): * runtime/WeakGCPtr.h: (JSC::WeakGCPtr::WeakGCPtr): (JSC::WeakGCPtr::set): 2011-02-24 Oliver Hunt Reviewed by Gavin Barraclough.

Bug 54988 - Re-create StructureTransitionTable class, encapsulate transition table The Structure class keeps a table of transitions to derived Structure types. Since this table commonly contains a single entry we employ an optimization where instead of holding a map, we may hold a pointer directly to a single instance of the mapped type. We use an additional bit of data to flag whether the pointer is currently pointing to a table of transitions, or a singleton transition. Previously we had commonly used a pattern of storing data in the low bits of pointers, but had moved away from this since it causes false leaks to be reported by the leaks tool. However in this case, the entries in the map are weak links - this pointer will never be responsible for keeping an object alive. As such we can use this approach provided that the bit is set when a table is not in use (otherwise the table would appear to be leaked). Additionally, the transition table currently allows two entries to exist for a given key - one specialized to a particular value, and one not specialized. This is unnecessary, wasteful, and a little inconsistent. (If you create an entry for a specialized value, then a non-specialized entry, both will exist. If you create an entry for a non-specialized value, then try to create a specialized entry, only a non-specialized form will be allowed.)

Historically, Native functions used to be represented by PrototypeFunctions, however since introducing call optimizations to the JIT this has used JSFunctions for host calls too. At the point this change was made, the interpreter continued to use PrototypeFunctions, however since fallback from the JIT to interpreter was introduced the interpreter has had to be able to run using host functions represented using JSFunctions - leading to an unnecessary and redundant divergence in behaviour between interpreter only builds, and situations where the JIT has fallen back to interpreting. NativeFunctionWrapper only existed to select between PrototypeFunction and JSFunction for wrappers for host functions, and as such can also be removed. GlobalEvalFunction is a redundant wrapper that happens to be derived from PrototypeFunction. It existed to hold a reference to the global object - but since all functions how derive from JSObjectWithGlobalObject, this no longer requires an additional class to provide this functionality. * JavaScriptCore.JSVALUE32_64only.exp: * JavaScriptCore.JSVALUE64only.exp: * JavaScriptCore.xcodeproj/project.pbxproj: Removed symbols / references to files. * runtime/GlobalEvalFunction.cpp: Removed. * runtime/GlobalEvalFunction.h: Removed. * runtime/NativeFunctionWrapper.h: Removed. * runtime/PrototypeFunction.cpp: Removed. * runtime/PrototypeFunction.h: Removed.

Bug 54786 - Devirtualize JSCell::classInfo() Instead of making a virtual function call, add a pointer to the ClassInfo onto Structure. This removes a virtual function call, and paves the way towards removing all the createStructure methods, and StructureFlags/AnonymousSlotCount properties (these should be able to move onto ClassInfo). Calls to Structure::create must now pass a pointer to the ClassInfo for the structure. All objects now have a ClassInfo pointer, non-object cell types still do not. Changes are most mechanical, involving three steps: * Remove virtual classInfo() methods. * Add &s_info parameter to calls to Structure::create. * Rename ClassInfo static members on classes from 'info' to 's_info', for consistency. * API/JSCallbackConstructor.cpp: * API/JSCallbackConstructor.h: * API/JSCallbackFunction.cpp: * API/JSCallbackFunction.h: * API/JSCallbackObject.cpp: * API/JSCallbackObject.h: * API/JSCallbackObjectFunctions.h: * API/JSObjectRef.cpp: * API/JSValueRef.cpp: * API/JSWeakObjectMapRefPrivate.cpp: * JavaScriptCore.exp: * debugger/Debugger.cpp: * debugger/DebuggerActivation.h: * debugger/DebuggerCallFrame.cpp: * interpreter/Interpreter.cpp: * jit/JITCall32_64.cpp: * jit/JITOpcodes.cpp: * jit/JITStubs.cpp: * profiler/Profiler.cpp: * runtime/Arguments.cpp: * runtime/Arguments.h: * runtime/ArrayConstructor.cpp: * runtime/ArrayPrototype.cpp: * runtime/ArrayPrototype.h: * runtime/BooleanObject.cpp: * runtime/BooleanObject.h: * runtime/BooleanPrototype.cpp: * runtime/DateConstructor.cpp: * runtime/DateInstance.cpp: * runtime/DateInstance.h: * runtime/DatePrototype.cpp: * runtime/DatePrototype.h: * runtime/ErrorInstance.cpp: * runtime/ErrorInstance.h: * runtime/ErrorPrototype.cpp: * runtime/FunctionPrototype.cpp: * runtime/FunctionPrototype.h: * runtime/GetterSetter.h: * runtime/GlobalEvalFunction.h: * runtime/InternalFunction.cpp: * runtime/InternalFunction.h: * runtime/JSAPIValueWrapper.h: * runtime/JSActivation.cpp: * runtime/JSActivation.h: * runtime/JSArray.cpp: * runtime/JSArray.h: * runtime/JSByteArray.cpp: * runtime/JSByteArray.h: * runtime/JSCell.cpp: * runtime/JSCell.h: * runtime/JSFunction.cpp: * runtime/JSFunction.h: * runtime/JSGlobalData.cpp: * runtime/JSGlobalObject.cpp: * runtime/JSGlobalObject.h: * runtime/JSNotAnObject.h: * runtime/JSONObject.cpp: * runtime/JSONObject.h: * runtime/JSObject.cpp: * runtime/JSObject.h: * runtime/JSObjectWithGlobalObject.h: * runtime/JSPropertyNameIterator.h: * runtime/JSStaticScopeObject.h: * runtime/JSString.h: * runtime/JSVariableObject.h: * runtime/JSWrapperObject.h: * runtime/JSZombie.cpp: * runtime/JSZombie.h: * runtime/Lookup.cpp: * runtime/MathObject.cpp: * runtime/MathObject.h: * runtime/NativeErrorConstructor.cpp: * runtime/NativeErrorConstructor.h: * runtime/NumberConstructor.cpp: * runtime/NumberConstructor.h: * runtime/NumberObject.cpp: * runtime/NumberObject.h: * runtime/NumberPrototype.cpp: * runtime/ObjectConstructor.cpp: * runtime/ObjectPrototype.cpp: * runtime/RegExpConstructor.cpp: * runtime/RegExpConstructor.h: * runtime/RegExpObject.cpp: * runtime/RegExpObject.h: * runtime/RegExpPrototype.cpp: * runtime/ScopeChain.cpp: * runtime/StringConstructor.cpp: * runtime/StringObject.cpp: * runtime/StringObject.h: * runtime/StringObjectThatMasqueradesAsUndefined.h: * runtime/StringPrototype.cpp: * runtime/StringPrototype.h: * runtime/Structure.cpp: * runtime/Structure.h: 2011-02-19 David Kilzer Change jsc target to build directly into JavaScriptCore.framework/Resources/jsc Reviewed by Dan Bernstein. * Configurations/Base.xcconfig: Added JAVASCRIPTCORE_FRAMEWORKS_DIR variable. * Configurations/JavaScriptCore.xcconfig: Used JAVASCRIPTCORE_FRAMEWORKS_DIR to define INSTALL_PATH. * JavaScriptCore.xcodeproj/project.pbxproj: Set the INSTALL_PATH for Production configuration of jsc target.
