Previously our terminology has been a little 6 mixed up, but we have decided to fix on refering to the process that takes place 7 at the end of code generation as 'linking', and on any modifications that take 8 place later (and once the code has potentially already been executed) as 'patching'. 9 10 However, the term 'PatchBuffer' is already in use, and needs to be repurposed. 11 12 To try to minimize confusion, we're going to switch the terminology over in stages, 13 so for now we'll refer to later modifications as 'repatching'. This means that the 14 new 'PatchBuffer' has been introduced with the name 'RepatchBuffer' instead. 15 16 This patch renames the old 'PatchBuffer' to 'LinkBuffer'. We'll leave ToT in this 17 state for a week or so to try to avoid to much overlap of the meaning of the term 18 'PatchBuffer', then will come back and rename 'RepatchBuffer'. 19 20 * assembler/ARMv7Assembler.h: 21 * assembler/AbstractMacroAssembler.h: 22 (JSC::AbstractMacroAssembler::LinkBuffer::LinkBuffer): 23 (JSC::AbstractMacroAssembler::LinkBuffer::~LinkBuffer): 24 * jit/JIT.cpp: 25 (JSC::JIT::privateCompile): 26 * jit/JITPropertyAccess.cpp: 27 (JSC::JIT::privateCompilePutByIdTransition): 28 (JSC::JIT::privateCompilePatchGetArrayLength): 29 (JSC::JIT::privateCompileGetByIdProto): 30 (JSC::JIT::privateCompileGetByIdSelfList): 31 (JSC::JIT::privateCompileGetByIdProtoList): 32 (JSC::JIT::privateCompileGetByIdChainList): 33 (JSC::JIT::privateCompileGetByIdChain): 34 * yarr/RegexJIT.cpp: 35 (JSC::Yarr::RegexGenerator::compile): 36 37 2009-06-15 Gavin Barraclough <barraclough (a] apple.com> 38 39 Reviewed by Sam Weinig. 40 41 Having moved most of their functionality into the RepatchBuffer class, 42 we can simplify the CodeLocation* classes. 43 44 The CodeLocation* classes are currently a tangle of templatey and friendly 45 badness, burried in the middle of AbstractMacroAssembler.

This makes it easier 1210 to work with the stub functions from assembler code (since the names no longer 1211 require mangling), and by delaring the functions with a macro we can look at 1212 also auto-generating asm thunks to wrap the JITStub functions to perform the 1213 work currently in 'restoreArgumentReference' (as a memory saving). 1214 1215 Making this change also forces us to be a bit more realistic about what is private 1216 on the Register and CallFrame objects. Presently most everything on these classes 1217 is private, and the classes have plenty of friends. We could befriend all the 1218 global functions to perpetuate the delusion of encapsulation, but using friends is 1219 a bit of a sledgehammer solution here - since friends can poke around with all of 1220 the class's privates, and since all the major classes taht operate on Regsiters are 1221 currently friends, right there is currently in practice very little protection at 1222 all.

This patch modifies the Structure class such that when a property is 1683 put to an object for the first time we will check if the value is a function. If it is, 1684 we will cache the function value on the Structure. A Structure in such a state guarantees 1685 that not only does a property with the given identifier exist on the object, but also that 1686 its value is unchanged. Upon any further attempt to put a property with the same identifier 1687 (but a different value) to the object, it will transition back to a normal Structure (where 1688 it will guarantee the presence but not the value of the property). 1689 1690 op_method_check makes use of the new information made available by the Structure, by 1691 augmenting the functionality of op_get_by_id. Upon generating a FunctionCallDotNode a 1692 check will be emitted prior to the property access reading the function value, and the JIT 1693 will generate an extra (initially unlinked but patchable) set of checks prior to the regular 1694 JIT code for get_by_id. The new code will do inline structure and prototype structure check 1695 (unlike a regular get_by_id, which can only handle 'self' accesses inline), and then performs 1696 an immediate load of the function value, rather than using memory accesses to load the value 1697 from the obejct's property storage array. If the method check fails it will revert, or if 1698 the access is polymorphic, the op_get_by_id will continue to operate - and optimize itself - 1699 just as any other regular op_get_by_id would.

To add to the mire, as well as the 1931 CodeBlock containing a handle onto the code the FunctionBodyNode also contains a 1932 copy of the code pointer which is used almost (but not entirely) uniquely to access 1933 the JIT code for a function. 1934 1935 Rationalization of all this: 1936 1937 * Add a new type 'MacroAssembler::CodeRef' as a handle for a block of JIT generated code. 1938 * Change the JIT & Yarr to internally handle code using CodeRefs. 1939 * Move the CodeRef (formerly anow defunct JITCodeRef) from CodeBlock to its owner node. 1940 * Remove the (now) redundant code pointer from FunctionBodyNode. 1941 1942 While tidying this up I've made the PatchBuffer return code in new allocations using a CodeRef, 1943 and have enforced an interface that the PatchBuffer will always be used, and 'finalizeCode()' or 1944 'finalizeCodeAddendum()' will always be called exactly once on the PatchBuffer to complete code generation. 1945 1946 This gives us a potentially useful hook ('PatchBuffer::performFinalization()') at the end of generation, 1947 which may have a number of uses. It may be helpful should we wish to switch our generation 1948 model to allow RW/RX exclusive memory, and it may be useful on non-cache-coherent platforms to 1949 give us an oportunity to cache flush as necessary. 1950 1951 No performance impact. 1952 1953 * assembler/AbstractMacroAssembler.h: 1954 (JSC::AbstractMacroAssembler::ProcessorReturnAddress::relinkCallerToTrampoline): 1955 (JSC::AbstractMacroAssembler::CodeRef::CodeRef): 1956 (JSC::AbstractMacroAssembler::CodeRef::trampolineAt): 1957 (JSC::AbstractMacroAssembler::PatchBuffer::PatchBuffer): 1958 (JSC::AbstractMacroAssembler::PatchBuffer::~PatchBuffer): 1959 (JSC::AbstractMacroAssembler::PatchBuffer::link): 1960 (JSC::AbstractMacroAssembler::PatchBuffer::linkTailRecursive): 1961 (JSC::AbstractMacroAssembler::PatchBuffer::patch): 1962 (JSC::AbstractMacroAssembler::PatchBuffer::complete): 1963 (JSC::AbstractMacroAssembler::PatchBuffer::finalize): 1964 (JSC::AbstractMacroAssembler::PatchBuffer::entry): 1965 * bytecode/CodeBlock.cpp: 1966 (JSC::CodeBlock::CodeBlock): 1967 (JSC::CodeBlock::reparseForExceptionInfoIfNecessary): 1968 (JSC::CodeBlock::setJITCode): 1969 * bytecode/CodeBlock.h: 1970 (JSC::CodeBlock::getBytecodeIndex): 1971 (JSC::CodeBlock::executablePool): 1972 * interpreter/CallFrameClosure.h: 1973 * interpreter/Interpreter.cpp: 1974 (JSC::Interpreter::execute): 1975 (JSC::Interpreter::prepareForRepeatCall): 1976 * jit/JIT.cpp: 1977 (JSC::JIT::privateCompile): 1978 (JSC::JIT::privateCompileCTIMachineTrampolines): 1979 (JSC::JIT::linkCall): 1980 * jit/JIT.h: 1981 * jit/JITCode.h: 1982 (JSC::JITCode::JITCode): 1983 (JSC::JITCode::operator bool): 1984 (JSC::JITCode::addressForCall): 1985 (JSC::JITCode::offsetOf): 1986 (JSC::JITCode::execute): 1987 (JSC::JITCode::size): 1988 (JSC::JITCode::executablePool): 1989 (JSC::JITCode::HostFunction): 1990 * jit/JITPropertyAccess.cpp: 1991 (JSC::JIT::privateCompilePutByIdTransition): 1992 (JSC::JIT::privateCompilePatchGetArrayLength): 1993 (JSC::JIT::privateCompileGetByIdProto): 1994 (JSC::JIT::privateCompileGetByIdSelfList): 1995 (JSC::JIT::privateCompileGetByIdProtoList): 1996 (JSC::JIT::privateCompileGetByIdChainList): 1997 (JSC::JIT::privateCompileGetByIdChain): 1998 * jit/JITStubs.cpp: 1999 (JSC::JITStubs::cti_vm_dontLazyLinkCall): 2000 (JSC::JITStubs::cti_vm_lazyLinkCall): 2001 * parser/Nodes.cpp: 2002 (JSC::ProgramNode::generateJITCode): 2003 (JSC::EvalNode::generateJITCode): 2004 (JSC::FunctionBodyNode::FunctionBodyNode): 2005 (JSC::FunctionBodyNode::createNativeThunk): 2006 (JSC::FunctionBodyNode::generateJITCode): 2007 * parser/Nodes.h: 2008 (JSC::ScopeNode::generatedJITCode): 2009 (JSC::ScopeNode::getExecutablePool): 2010 (JSC::ScopeNode::setJITCode): 2011 (JSC::ProgramNode::jitCode): 2012 (JSC::EvalNode::jitCode): 2013 (JSC::FunctionBodyNode::jitCode): 2014 * runtime/RegExp.cpp: 2015 (JSC::RegExp::match): 2016 * yarr/RegexJIT.cpp: 2017 (JSC::Yarr::RegexGenerator::compile): 2018 (JSC::Yarr::jitCompileRegex): 2019 (JSC::Yarr::executeRegex): 2020 * yarr/RegexJIT.h: 2021 (JSC::Yarr::RegexCodeBlock::RegexCodeBlock): 2022 (JSC::Yarr::RegexCodeBlock::pcreFallback): 2023 (JSC::Yarr::RegexCodeBlock::setFallback): 2024 (JSC::Yarr::RegexCodeBlock::operator bool): 2025 (JSC::Yarr::RegexCodeBlock::set): 2026 (JSC::Yarr::RegexCodeBlock::execute): 2027 2028 2009-05-21 Oliver Hunt <oliver (a] apple.com> 2029 2030 Reviewed by Maciej Stachowiak. 2031 2032 <rdar://problem/6910264> REGRESSION: Cached DOM global object property access fails in browser (25921) 2033 <https://bugs.webkit.org/show_bug.cgi?id=25921> 2034 2035 When caching properties on the global object we need to ensure that we're 2036 not attempting to cache through a shell object. 2037 2038 * interpreter/Interpreter.cpp: 2039 (JSC::Interpreter::resolveGlobal): 2040 * jit/JITStubs.cpp: 2041 (JSC::JITStubs::cti_op_resolve_global): 2042 2043 2009-05-21 Steve Falkenburg <sfalken (a] apple.com> 2044 2045 Windows build fix. 2046 2047 * JavaScriptCore.vcproj/jsc/jscCommon.vsprops: 2048 2049 2009-05-21 Cameron Zwarich <zwarich (a] apple.com> 2050 2051 Reviewed by Mark Rowe. 2052 2053 Bug 25945: Add support for MADV_FREE to TCMalloc 2054 <https://bugs.webkit.org/show_bug.cgi?id=25945> 2055 <rdar://problem/6910754> 2056 2057 Add support for MADV_FREE to TCMalloc_SystemRelease for platforms that 2058 don't also support MADV_FREE_REUSE.

Changed 2688 SET_EXCEPTION_LOCATION from a macro to an inline function. Marked 2689 the structure-creating functions inline. Changed the VarStack to use 2690 identifier pointers instead of actual identifiers. This takes 2691 advantage of the fact that all identifier pointers come from the 2692 arena and avoids reference count churn. Changed Identifier* to 2693 const Identifier* to make sure we don't modify any by accident. 2694 Used identifiers for regular expression strings too, using the new 2695 scanRegExp that has out parameters instead of the old one that relied 2696 on side effects in the Lexer. Move the creation of numeric identifiers 2697 out of this file and into the PropertyNode constructor. 2698 2699 * parser/Lexer.cpp: 2700 (JSC::Lexer::setCode): Pass in ParserArena, used for identifiers. 2701 (JSC::Lexer::makeIdentifier): Changed return type to const Identifier* 2702 and changed to call ParserArena. 2703 (JSC::Lexer::scanRegExp): Added out arguments that are const Identifier* 2704 as well as a prefix character argument so we can handle the /= case 2705 without a string append. 2706 (JSC::Lexer::skipRegExp): Added. Skips a regular expression without 2707 allocating Identifier objects. 2708 (JSC::Lexer::clear): Removed the code to manage m_identifiers, m_pattern, 2709 and m_flags, and added code to set m_arena to 0. 2710 * parser/Lexer.h: Updated for changes above. 2711 2712 * parser/NodeConstructors.h: 2713 (JSC::ParserArenaFreeable::operator new): Added. Calls allocateFreeable 2714 on the arena. 2715 (JSC::ParserArenaDeletable::operator new): Changed to call the 2716 allocateDeletable function on the arena instead of deleteWithArena. 2717 (JSC::RegExpNode::RegExpNode): Changed arguments to Identifier instead 2718 of UString since these come from the parser which makes identifiers. 2719 (JSC::PropertyNode::PropertyNode): Added new constructor that makes 2720 numeric identifiers. Some day we might want to optimize this for 2721 integers so it doesn't create a string for each one. 2722 (JSC::ContinueNode::ContinueNode): Initialize m_ident to nullIdentifier 2723 since it's now a const Identifier& so it can't be left uninitialized. 2724 (JSC::BreakNode::BreakNode): Ditto. 2725 (JSC::CaseClauseNode::CaseClauseNode): Updated to use SourceElements* 2726 to keep track of the statements rather than a separate statement vector. 2727 (JSC::BlockNode::BlockNode): Ditto. 2728 (JSC::ForInNode::ForInNode): Initialize m_ident to nullIdentifier. 2729 2730 * parser/Nodes.cpp: Moved the comment explaining emitBytecode in here. 2731 It seemed strangely out of place in the header. 2732 (JSC::ThrowableExpressionData::emitThrowError): Added an overload for 2733 UString as well as Identifier. 2734 (JSC::SourceElements::singleStatement): Added. 2735 (JSC::SourceElements::lastStatement): Added. 2736 (JSC::RegExpNode::emitBytecode): Updated since the pattern and flags 2737 are now Identifier instead of UString. Also changed the throwError code 2738 to use the substitution mechanism instead of doing a string append. 2739 (JSC::SourceElements::emitBytecode): Added. Replaces the old 2740 statementListEmitCode function, since we now keep the SourceElements 2741 objects around. 2742 (JSC::BlockNode::lastStatement): Added. 2743 (JSC::BlockNode::emitBytecode): Changed to use emitBytecode instead of 2744 statementListEmitCode. 2745 (JSC::CaseClauseNode::emitBytecode): Added. 2746 (JSC::CaseBlockNode::emitBytecodeForBlock): Changed to use emitBytecode 2747 instead of statementListEmitCode. 2748 (JSC::ScopeNodeData::ScopeNodeData): Changed to store the 2749 SourceElements* instead of using releaseContentsIntoVector. 2750 (JSC::ScopeNode::emitStatementsBytecode): Added. 2751 (JSC::ScopeNode::singleStatement): Added. 2752 (JSC::ProgramNode::emitBytecode): Call emitStatementsBytecode instead 2753 of statementListEmitCode. 2754 (JSC::EvalNode::emitBytecode): Ditto. 2755 (JSC::EvalNode::generateBytecode): Removed code to clear the children 2756 vector. This optimization is no longer possible since everything is in 2757 a single arena. 2758 (JSC::FunctionBodyNode::emitBytecode): Call emitStatementsBytecode 2759 insetad of statementListEmitCode and check for the return node using 2760 the new functions. 2761 2762 * parser/Nodes.h: Changed VarStack to store const Identifier* instead 2763 of Identifier and rely on the arena to control lifetime. Added a new 2764 ParserArenaFreeable class. Made ParserArenaDeletable inherit from 2765 FastAllocBase instead of having its own operator new. Base the Node 2766 class on ParserArenaFreeable. Changed the various Node classes 2767 to use const Identifier& instead of Identifier to avoid the need to 2768 call their destructors and allow them to function as "freeable" in the 2769 arena. Removed extraneous JSC_FAST_CALL on definitions of inline functions. 2770 Changed ElementNode, PropertyNode, ArgumentsNode, ParameterNode, 2771 CaseClauseNode, ClauseListNode, and CaseBlockNode to use ParserArenaFreeable 2772 as a base class since they do not descend from Node. Eliminated the 2773 StatementVector type and instead have various classes use SourceElements* 2774 instead of StatementVector. This prevents those classes from having th 2775 use ParserArenaDeletable to make sure the vector destructor is called. 2776 2777 * parser/Parser.cpp: 2778 (JSC::Parser::parse): Pass the arena to the lexer. 2779 2780 * parser/Parser.h: Added an include of ParserArena.h, which is no longer 2781 included by Nodes.h. 2782 2783 * parser/ParserArena.cpp: 2784 (JSC::ParserArena::ParserArena): Added. Initializes the new members, 2785 m_freeableMemory, m_freeablePoolEnd, and m_identifiers. 2786 (JSC::ParserArena::freeablePool): Added. Computes the pool pointer, 2787 since we store only the current pointer and the end of pool pointer. 2788 (JSC::ParserArena::deallocateObjects): Added. Contains the common 2789 memory-deallocation logic used by both the destructor and the 2790 reset function. 2791 (JSC::ParserArena::~ParserArena): Changed to call deallocateObjects. 2792 (JSC::ParserArena::reset): Ditto. Also added code to zero out the 2793 new structures, and switched to use clear() instead of shrink(0) since 2794 we don't really reuse arenas. 2795 (JSC::ParserArena::makeNumericIdentifier): Added. 2796 (JSC::ParserArena::allocateFreeablePool): Added. Used when the pool 2797 is empty. 2798 (JSC::ParserArena::isEmpty): Added. No longer inline, which is fine 2799 since this is used only for assertions at the moment. 2800 2801 * parser/ParserArena.h: Added an actual arena of "freeable" objects, 2802 ones that don't need destructors to be called. Also added the segmented 2803 vector of identifiers that used to be in the Lexer. 2804 2805 * runtime/FunctionConstructor.cpp: 2806 (JSC::extractFunctionBody): Use singleStatement function rather than 2807 getting at a StatementVector. 2808 2809 * runtime/FunctionPrototype.cpp: 2810 (JSC::functionProtoFuncToString): Call isHostFunction on the body 2811 rather than the function object. 2812 2813 * runtime/JSFunction.cpp: 2814 (JSC::JSFunction::JSFunction): Moved the structure version of this in 2815 here from the header. It's not hot enough that it needs to be inlined. 2816 (JSC::JSFunction::isHostFunction): Moved this in here from the header. 2817 It's now a helper to be used only within the class. 2818 (JSC::JSFunction::setBody): Moved this in here. It's not hot enough that 2819 it needs to be inlined, and we want to be able to compile the header 2820 without the definition of FunctionBodyNode. 2821 2822 * runtime/JSFunction.h: Eliminated the include of "Nodes.h". This was 2823 exposing too much JavaScriptCore dependency to WebCore. Because of this 2824 change and some changes made to WebCore, we could now export a lot fewer 2825 headers from JavaScriptCore, but I have not done that yet in this check-in. 2826 Made a couple functions non-inline.

The codeblock sampling tool has become 4112 b0rked due to recent changes in native function calling. The initialization of 4113 a ScopeNode appears to now occur before the sampling tool (or possibly the 4114 interpreter has been brought into existence, wihich leads to crashyness). 4115 4116 This patch doesn't fix the problem. The crash occurs when tracking a Scope, but 4117 we shouldn't need to track scopes when we're just sampling opcodes, not 4118 codeblocks. Not retaining Scopes when just opcode sampling will reduce sampling 4119 overhead reducing any instrumentation skew, which is a good thing. As a side 4120 benefit this patch also gets the opcode sampling going again, albeit in a bit of 4121 a lame way. Will come back later with a proper fix from codeblock sampling. 4122 4123 * JavaScriptCore.exp: 4124 * bytecode/SamplingTool.cpp: 4125 (JSC::compareLineCountInfoSampling): 4126 (JSC::SamplingTool::dump): 4127 * bytecode/SamplingTool.h: 4128 (JSC::SamplingTool::SamplingTool): 4129 * parser/Nodes.cpp: 4130 (JSC::ScopeNode::ScopeNode): 4131 4132 2009-05-07 Mark Rowe <mrowe (a] apple.com> 4133 4134 Rubber-stamped by Oliver Hunt. 4135 4136 Fix <https://bugs.webkit.org/show_bug.cgi?id=25640>. 4137 Bug 25640: Crash on quit in r43384 nightly build on Leopard w/ Safari 4 beta installed 4138 4139 Roll out r43366 as it removed symbols that Safari 4 Beta uses. 4140 4141 * JavaScriptCore.exp: 4142 * JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.def: 4143 * JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore_debug.def: 4144 * bytecode/SamplingTool.cpp: 4145 (JSC::SamplingThread::start): 4146 (JSC::SamplingThread::stop): 4147 * bytecode/SamplingTool.h: 4148 * wtf/CrossThreadRefCounted.h: 4149 (WTF::CrossThreadRefCounted::CrossThreadRefCounted): 4150 (WTF::::ref): 4151 (WTF::::deref): 4152 * wtf/Threading.h: 4153 * wtf/ThreadingNone.cpp: 4154 * wtf/ThreadingPthreads.cpp: 4155 (WTF::threadMapMutex): 4156 (WTF::initializeThreading): 4157 (WTF::threadMap): 4158 (WTF::identifierByPthreadHandle): 4159 (WTF::establishIdentifierForPthreadHandle): 4160 (WTF::pthreadHandleForIdentifier): 4161 (WTF::clearPthreadHandleForIdentifier): 4162 (WTF::createThreadInternal): 4163 (WTF::waitForThreadCompletion): 4164 (WTF::detachThread): 4165 (WTF::currentThread): 4166 * wtf/ThreadingWin.cpp: 4167 (WTF::threadMapMutex): 4168 (WTF::initializeThreading): 4169 (WTF::threadMap): 4170 (WTF::storeThreadHandleByIdentifier): 4171 (WTF::threadHandleForIdentifier): 4172 (WTF::clearThreadHandleForIdentifier): 4173 (WTF::createThreadInternal): 4174 (WTF::waitForThreadCompletion): 4175 (WTF::detachThread): 4176 (WTF::currentThread): 4177 * wtf/gtk/ThreadingGtk.cpp: 4178 (WTF::threadMapMutex): 4179 (WTF::initializeThreading): 4180 (WTF::threadMap): 4181 (WTF::identifierByGthreadHandle): 4182 (WTF::establishIdentifierForThread): 4183 (WTF::threadForIdentifier): 4184 (WTF::clearThreadForIdentifier): 4185 (WTF::createThreadInternal): 4186 (WTF::waitForThreadCompletion): 4187 (WTF::currentThread): 4188 * wtf/qt/ThreadingQt.cpp: 4189 (WTF::threadMapMutex): 4190 (WTF::threadMap): 4191 (WTF::identifierByQthreadHandle): 4192 (WTF::establishIdentifierForThread): 4193 (WTF::clearThreadForIdentifier): 4194 (WTF::threadForIdentifier): 4195 (WTF::initializeThreading): 4196 (WTF::createThreadInternal): 4197 (WTF::waitForThreadCompletion): 4198 (WTF::currentThread): 4199 4200 2009-05-07 Gustavo Noronha Silva <gns (a] gnome.org> 4201 4202 Suggested by Oliver Hunt. 4203 4204 Also check for Linux for the special-cased calling convention. 4205 4206 * jit/JIT.cpp: 4207 (JSC::JIT::privateCompileCTIMachineTrampolines): 4208 * wtf/Platform.h: 4209 4210 2009-05-07 Gavin Barraclough <barraclough (a] apple.com> 4211 4212 Reviewed by Maciej Stachowiak. 4213 4214 Previously, when appending to an existing string and growing the underlying buffer, 4215 we would actually allocate 110% of the required size in order to give us some space 4216 to expand into.

It was attempting 10091 to record the memory containing and individual span as an administrative region, when all memory 10092 allocated via MetaDataAlloc should in fact be recorded. This was causing memory regions allocated 10093 via MetaDataAlloc to appear as "VM_ALLOCATE ?" in vmmap output. They are now correctly reported as 10094 "MALLOC_OTHER" regions associated with the JavaScriptCore FastMalloc zone. 10095 10096 Memory is allocated via MetaDataAlloc from two locations: PageHeapAllocator, and TCMalloc_PageMap{2,3}. 10097 These two cases are handled differently. 10098 10099 PageHeapAllocator is extended to keep a linked list of memory regions that it has allocated. The 10100 first object in an allocated region contains the link to the previously allocated region. To record 10101 the administrative regions of a PageHeapAllocator we can simply walk the linked list and record 10102 each allocated region we encounter. 10103 10104 TCMalloc_PageMaps allocate memory via MetaDataAlloc to store each level of the radix tree. To record 10105 the administrative regions of a TCMalloc_PageMap we walk the tree and record the storage used for nodes 10106 at each position rather than the nodes themselves. 10107 10108 A small performance improvement is achieved by coalescing adjacent memory regions inside the PageMapMemoryUsageRecorder 10109 so that fewer calls in to the range recorder are necessary. We further reduce the number of calls to the 10110 range recorder by aggregating the in-use ranges of a given memory region into a local buffer before recording 10111 them with a single call. A similar approach is also used by AdminRegionRecorder. 10112 10113 * wtf/FastMalloc.cpp: 10114 (WTF::PageHeapAllocator::Init): 10115 (WTF::PageHeapAllocator::New): 10116 (WTF::PageHeapAllocator::recordAdministrativeRegions): 10117 (WTF::TCMallocStats::FreeObjectFinder::isFreeObject): 10118 (WTF::TCMallocStats::PageMapMemoryUsageRecorder::~PageMapMemoryUsageRecorder): 10119 (WTF::TCMallocStats::PageMapMemoryUsageRecorder::recordPendingRegions): 10120 (WTF::TCMallocStats::PageMapMemoryUsageRecorder::visit): 10121 (WTF::TCMallocStats::AdminRegionRecorder::AdminRegionRecorder): 10122 (WTF::TCMallocStats::AdminRegionRecorder::recordRegion): 10123 (WTF::TCMallocStats::AdminRegionRecorder::visit): 10124 (WTF::TCMallocStats::AdminRegionRecorder::recordPendingRegions): 10125 (WTF::TCMallocStats::AdminRegionRecorder::~AdminRegionRecorder): 10126 (WTF::TCMallocStats::FastMallocZone::enumerate): 10127 (WTF::TCMallocStats::FastMallocZone::FastMallocZone): 10128 (WTF::TCMallocStats::FastMallocZone::init): 10129 * wtf/TCPageMap.h: 10130 (TCMalloc_PageMap2::visitValues): 10131 (TCMalloc_PageMap2::visitAllocations): 10132 (TCMalloc_PageMap3::visitValues): 10133 (TCMalloc_PageMap3::visitAllocations): 10134 10135 2009-03-04 Antti Koivisto <antti (a] apple.com> 10136 10137 Reviewed by Dave Hyatt. 10138 10139 https://bugs.webkit.org/show_bug.cgi?id=24359 10140 Repaint throttling mechanism 10141 10142 Set ENABLE_REPAINT_THROTTLING to 0 by default. 10143 10144 * wtf/Platform.h: 10145 10146 2009-03-03 David Kilzer <ddkilzer (a] apple.com> 10147 10148 <rdar://problem/6581203> WebCore and WebKit should install the same set of headers during installhdrs phase as build phase 10149 10150 Reviewed by Mark Rowe. 10151 10152 * Configurations/Base.xcconfig: Defined REAL_PLATFORM_NAME based 10153 on PLATFORM_NAME to work around the missing definition on Tiger. 10154 Updated HAVE_DTRACE to use REAL_PLATFORM_NAME. 10155 10156 2009-03-03 Kevin McCullough <kmccullough (a] apple.com> 10157 10158 Reviewed by Oliver Hunt. 10159 10160 <rdar://problem/6639110> console.profile() doesn't work without a title 10161 10162 * profiler/Profiler.cpp: 10163 (JSC::Profiler::startProfiling): assert if there is not title to ensure 10164 we don't start profiling without one. 10165 10166 2009-03-02 Sam Weinig <sam (a] webkit.org> 10167 10168 Reviewed by Mark Rowe. 10169 10170 Enable Geolocation (except on Tiger and Leopard). 10171 10172 * Configurations/JavaScriptCore.xcconfig: 10173 10174 2009-03-01 David Kilzer <ddkilzer (a] apple.com> 10175 10176 <rdar://problem/6635688> Move HAVE_DTRACE check to Base.xcconfig 10177 10178 Reviewed by Mark Rowe. 10179 10180 * Configurations/Base.xcconfig: Set HAVE_DTRACE Xcode variable 10181 based on PLATFORM_NAME and MAC_OS_X_VERSION_MAJOR.

The MacroAssembler gets split up like a beef burger, with the 11658 platform-agnostic data types being the lower bun (in the form of the class AbstractMacroAssembler), 11659 the plaform-specific code generation forming a big meaty patty of methods like 'add32', 11660 'branch32', etc (MacroAssemblerX86), and finally topped off with the bun-lid of the 11661 MacroAssembler class itself, providing covenience methods such as the stack peek & poke, 11662 and backwards branch methods, all of which can be described in a platform independent 11663 way using methods from the base class. The AbstractMacroAssembler is templated on the 11664 type of the assembler class that will be used for code generation, and the three layers 11665 are held together with the cocktail stick of inheritance. 11666 11667 The above description is a slight simplification since the MacroAssemblerX86 is actually 11668 formed from two layers (in effect giving us a kind on bacon double cheeseburger) - with the 11669 bulk of methods that are common between x86 & x86-64 implemented in MacroAssemblerX86Common, 11670 which forms a base class for MacroAssemblerX86 and MacroAssemblerX86_64 (which add the methods 11671 specific to the given platform). 11672 11673 I'm landing these changes first without splitting the classes across multiple files, 11674 I will follow up with a second patch to split

Since a 14316 value may dynamically need to contain either a pointer value or an immediate, 14317 we encode immediates as pointer values (since all valid JSCell pointers are 14318 allocated at alligned addesses, unaligned addresses are available to encode 14319 immediates). As such all JavaScript values are represented using a JSValue*. 14320 14321 This implementation is encumbered by a number of constraints. It ties the 14322 JSValue representation to the size of pointer on the platform, which, for 14323 example, means that we currently can represent different ranges of integers 14324 as immediates on x86 and x86-64. It also prevents us from overloading the 14325 to-boolean conversion used to test for noValue() - effectively forcing us 14326 to represent noValue() as 0. This would potentially be problematic were we 14327 to wish to encode integer values differently (e.g. were we to use the v8 14328 encoding, where pointers are tagged with 1 and integers with 0, then the 14329 immediate integer 0 would conflict with noValue()). 14330 14331 This patch replaces all usage of JSValue* with a new class, JSValuePtr, 14332 which encapsulates the pointer. JSValuePtr maintains the same interface as 14333 JSValue*, overloading operator-> and operator bool such that previous 14334 operations in the code on variables of type JSValue* are still supported. 14335 14336 In order to provide a ProtectPtr<> type with support for the new value 14337 representation (without using the internal JSValue type directly), a new 14338 ProtectJSValuePtr type has been added, equivalent to the previous type 14339 ProtectPtr<JSValue>. 14340 14341 This patch is likely the first in a sequence of three changes. With the 14342 value now encapsulated it will likely make sense to migrate the functionality 14343 from JSValue into JSValuePtr, such that the internal pointer representation 14344 need not be exposed. Through migrating the functionality to the wrapper 14345 class the existing JSValue should be rendered redundant, and the class is 14346 likely to be removed (the JSValuePtr now wrapping a pointer to a JSCell). 14347 At this stage it will likely make sense to rename JSValuePtr to JSValue. 14348 14349 https://bugs.webkit.org/show_bug.cgi?id=23114 14350 14351 * API/APICast.h: 14352 (toJS): 14353

It is not that big of 15757 an issue in practice, because in a Release build such a function will return 15758 'undefined' when called. 15759 15760 In this case, we are not following the spec and it should be a syntax error. 15761 However, unless there is a newline separating the ',' and the '}', WebKit would 15762 not treat it as a syntax error in the past either. It would be a bit of work to 15763 make the automatic semicolon insertion match the spec exactly, so this patch 15764 changes it to match our past behaviour. 15765 15766 The problem is that even during reparsing, the Lexer adds a semicolon at the 15767 end of the input, which confuses allowAutomaticSemicolon(), because it is 15768 expecting either a '}', the end of input, or a terminator like a newline. 15769 15770 * parser/Lexer.cpp: 15771 (JSC::Lexer::Lexer): Initialize m_isReparsing to false. 15772 (JSC::Lexer::lex): Do not perform automatic semicolon insertion in the Lexer if 15773 we are in the middle of reparsing. 15774 (JSC::Lexer::clear): Set m_isReparsing to false. 15775 * parser/Lexer.h: 15776 (JSC::Lexer::setIsReparsing): Added. 15777 * parser/Parser.cpp: 15778 (JSC::Parser::reparse): Call Lexer::setIsReparsing() to notify the Lexer of 15779 reparsing. 15780 15781 2008-12-29 Oliver Hunt <oliver (a] apple.com> 15782 15783 Reviewed by NOBODY (Build fix). 15784 15785 Yet another attempt to fix Tiger. 15786 15787 * wtf/RandomNumber.cpp: 15788 (WTF::randomNumber): 15789 15790 2008-12-29 Oliver Hunt <oliver (a] apple.com> 15791 15792 Reviewed by NOBODY (Build fix). 15793 15794 Tiger build fix (correct this time) 15795 15796 * wtf/RandomNumber.cpp: 15797 15798 2008-12-29 Cameron Zwarich <cwzwarich (a] uwaterloo.ca> 15799 15800 Rubber-stamped by Alexey Proskuryakov. 15801 15802 Revert r39509, because kjsyydebug is used in the generated code if YYDEBUG is 1. 15803 15804 * parser/Grammar.y: 15805 15806 2008-12-29 Oliver Hunt <oliver (a] apple.com> 15807 15808 Reviewed by NOBODY (Build fix). 15809 15810 Tiger build fix. 15811 15812 * wtf/RandomNumber.cpp: 15813 15814 2008-12-29 Oliver Hunt <oliver (a] apple.com> 15815 15816 Reviewed by Mark Rowe. 15817 15818 <rdar://problem/6358108> Insecure randomness in Math.random() leads to user tracking 15819 15820 Switch to arc4random on PLATFORM(DARWIN), this is ~1.5x slower than random(), but the 15821 it is still so fast that there is no fathomable way it could be a bottleneck for anything. 15822 15823 randomNumber is called in two places 15824 * During form submission where it is called once per form 15825 * Math.random in JSC.

values on x86-64. 16228 On 64-bit systems, the code in JSImmediate.h relies on the upper 16229 bits of a JSImmediate being a sign extension of the low 32-bits. 16230 This was not being enforced by the JIT, since a number of inline 16231 operations were being performed on 32-bit values in registers, and 16232 when a 32-bit result is written to a register on x86-64 the value 16233 is zero-extended to 64-bits. 16234 16235 This fix honors previous behavoir. A better fix in the long run 16236 (when the JIT is enabled by default) may be to change JSImmediate.h 16237 so it no longer relies on the upper bits of the pointer,... though 16238 if we're going to change JSImmediate.h for 64-bit, we probably may 16239 as well change the format so that the full range of 32-bit ints can 16240 be stored, rather than just 31-bits. 16241 16242

Acknowledging this 23670 and that PropertyMaps stored in StructureIDs can be treated as caches, that 23671 is that they can be reconstructed on demand, it became clear that we could 23672 reduce the memory consumption of StructureIDs by only keeping PropertyMaps 23673 for the StructureIDs that need them the most. 23674 23675 The specific strategy used to reduce the number of StructureIDs with 23676 PropertyMaps is to take the previous StructureIDs PropertyMap when initially 23677 transitioning (addPropertyTransition) from it and clearing out the pointer 23678 in the process. The next time we need to do the same transition, for instance 23679 repeated calls to the same constructor, we use the new addPropertyTransitionToExistingStructure 23680 first, which allows us not to need the PropertyMap to determine if the property 23681 exists already, since a transition to that property would require it not already 23682 be present in the StructureID. Should there be no transition, the PropertyMap 23683 can be constructed on demand (via materializePropertyMap) to determine if the put is a 23684 replace or a transition to a new StructureID. 23685 23686 Reduces memory use on Membuster head test (30 pages open) by ~15MB. 23687 23688 * JavaScriptCore.exp: 23689 * runtime/JSObject.h: 23690 (JSC::JSObject::putDirect): First use addPropertyTransitionToExistingStructure 23691 so that we can avoid building the PropertyMap on subsequent similar object 23692 creations. 23693 * runtime/PropertyMapHashTable.h: 23694 (JSC::PropertyMapEntry::PropertyMapEntry): Add version of constructor which takes 23695 all values to be used when lazily building the PropertyMap. 23696 * runtime/StructureID.cpp: 23697 (JSC::StructureID::dumpStatistics): Add statistics on the number of StructureIDs 23698 with PropertyMaps. 23699 (JSC::StructureID::StructureID): Rename m_cachedTransistionOffset to m_offset 23700 (JSC::isPowerOf2): 23701 (JSC::nextPowerOf2): 23702 (JSC::sizeForKeyCount): Returns the expected size of a PropertyMap for a key count. 23703 (JSC::StructureID::materializePropertyMap): Builds the PropertyMap out of its previous pointer chain. 23704 (JSC::StructureID::addPropertyTransitionToExistingStructure): Only transitions if there is a 23705 an existing transition. 23706 (JSC::StructureID::addPropertyTransition): Instead of always copying the ProperyMap, try and take 23707 it from it previous pointer. 23708 (JSC::StructureID::removePropertyTransition): Simplify by calling toDictionaryTransition() to do 23709 transition work. 23710 (JSC::StructureID::changePrototypeTransition): Build the PropertyMap if necessary before transitioning 23711 because once you have transitioned, you will not be able to reconstruct it afterwards as there is no 23712 previous pointer, pinning the ProperyMap as well. 23713 (JSC::StructureID::getterSetterTransition): Ditto. 23714 (JSC::StructureID::toDictionaryTransition): Pin the PropertyMap so that it is not destroyed on further transitions. 23715 (JSC::StructureID::fromDictionaryTransition): We can only transition back from a dictionary transition if there 23716 are no deleted offsets. 23717 (JSC::StructureID::addPropertyWithoutTransition): Build PropertyMap on demands and pin. 23718 (JSC::StructureID::removePropertyWithoutTransition): Ditto. 23719 (JSC::StructureID::get): Build on demand. 23720 (JSC::StructureID::createPropertyMapHashTable): Add version of create that takes a size 23721 for on demand building. 23722 (JSC::StructureID::expandPropertyMapHashTable): 23723 (JSC::StructureID::rehashPropertyMapHashTable): 23724 (JSC::StructureID::getEnumerablePropertyNamesInternal): Build PropertyMap on demand. 23725 * runtime/StructureID.h: 23726 (JSC::StructureID::propertyStorageSize): Account for StructureIDs without PropertyMaps. 23727 (JSC::StructureID::isEmpty): Ditto. 23728 (JSC::StructureID::materializePropertyMapIfNecessary): 23729 (JSC::StructureID::get): Build PropertyMap on demand 23730 23731 2008-11-14 Csaba Osztrogonac <oszi (a] inf.u-szeged.hu> 23732 23733 Reviewed by Simon Hausmann. 23734 23735 <https://bugs.webkit.org/show_bug.cgi?id=21500> 23736 23737 JavaScriptCore build with -O3 flag instead of -O2 (gcc). 23738 2.02% speedup on SunSpider (Qt-port on Linux) 23739 1.10% speedup on V8 (Qt-port on Linux) 23740 3.45% speedup on WindScorpion (Qt-port on Linux) 23741 23742 * JavaScriptCore.pri: 23743 23744 2008-11-14 Kristian Amlie <kristian.amlie (a] trolltech.com> 23745 23746 Reviewed by Darin Adler. 23747 23748 Compile fix for RVCT. 23749 23750 In reality, it is two fixes: 23751 23752 1.

For temporaries, the only problematic 23967 jump targets are binary logical operators and the ternary conditional 23968 operator. However, if this optimization were to be extended to local 23969 variable registers as well, other jump targets would need to be 23970 included, like switch statement cases and the beginnings of catch 23971 blocks. 23972 23973 This optimization also requires that the fast case and the slow case 23974 of an opcode use emitPutResult() on the same register, which was chosen 23975 to be eax, as that is the register into which we read the first operand 23976 of opcodes. In order to make this the case, we needed to add some mov 23977 instructions to the slow cases of some instructions. 23978 23979 This optimizaton is not applied whenever compileBinaryArithOp() is used 23980 to compile an opcode, because different machine registers may be used to 23981 store the final result. It seems possible to rewrite the code generation 23982 in compileBinaryArithOp() to allow for this optimization. 23983 23984 This optimization is also not applied when generating slow cases, 23985 because some fast cases overwrite the value of eax before jumping to the 23986 slow case. In the future, it may be possible to apply this optimization 23987 to slow cases as well, but it did not seem to be a speedup when testing 23988 an early version of this patch. 23989 23990 This is a 1.0% speedup on SunSpider and a 6.3% speedup on the V8 23991 benchmark suite. 23992 23993 * VM/CTI.cpp: 23994 (JSC::CTI::killLastResultRegister): 23995 (JSC::CTI::emitGetArg): 23996 (JSC::CTI::emitGetPutArg): 23997 (JSC::CTI::emitGetCTIParam): 23998 (JSC::CTI::emitGetFromCallFrameHeader): 23999 (JSC::CTI::emitPutResult): 24000 (JSC::CTI::emitCTICall): 24001 (JSC::CTI::CTI): 24002 (JSC::CTI::compileOpCall): 24003 (JSC::CTI::compileOpStrictEq): 24004 (JSC::CTI::emitSlowScriptCheck): 24005 (JSC::CTI::compileBinaryArithOp): 24006 (JSC::CTI::privateCompileMainPass): 24007 (JSC::CTI::privateCompileSlowCases): 24008 (JSC::CTI::privateCompileGetByIdProto): 24009 (JSC::CTI::privateCompilePatchGetArrayLength): 24010 * VM/CTI.h: 24011 * VM/CodeBlock.h: 24012 (JSC::CodeBlock::isTemporaryRegisterIndex): 24013 * bytecompiler/CodeGenerator.cpp: 24014 (JSC::CodeGenerator::emitLabel): 24015 24016 2008-11-12 Alp Toker <alp (a] nuanti.com> 24017 24018 autotools build system fix-up only.

The storage leak was caused by the fact 25698 that HashTraits<CallIdentifier>::needsDestruction was false, so 25699 the call identifier objects didn't get deleted. 25700 25701 * profiler/CallIdentifier.h: 25702 25703 Added a default constructor to create empty call identifiers. 25704 25705 Changed the normal constructor to use const UString& 25706 to avoid extra copying and reference count thrash. 25707 25708 Removed the explicit copy constructor definition, since it's what 25709 the compiler will automatically generate. (Rule of thumb: Either 25710 you need both a custom copy constructor and a custom assignment 25711 operator, or neither.) 25712 25713 Moved the CallIdentifier hash function out of the WTF namespace; 25714 there's no reason to put it there. 25715 25716 Changed the CallIdentifier hash function to be a struct rather than 25717 a specialization of the IntHash struct template. Having it be 25718 a specialization made no sense, since CallIdentifier is not an integer, 25719 and did no good. 25720 25721 Removed explicit definition of emptyValueIsZero in the hash traits, 25722 since inheriting from GenericHashTraits already makes that false. 25723 25724 Removed explicit definition of emptyValue, instead relying on the 25725 default constructor and GenericHashTraits. 25726 25727 Removed explicit definition of needsDestruction, because we want it 25728 to have its default value: true, not false. This fixes the leak! 25729 25730 Changed constructDeletedValue and isDeletedValue to use a line number 25731 of numeric_limits<unsigned>::max() to indicate a value is deleted. 25732 Previously this used empty strings for the empty value and null strings 25733 for the deleted value, but it's more efficient to use null for both. 25734 25735 2008-10-31 Timothy Hatcher <timothy (a] apple.com> 25736 25737 Emit the WillExecuteStatement debugger hook before the for loop body 25738 when the statement node for the body isn't a block.

(This required passing the current vPC to a lot 26598 more functions, since the unified interface samples the current vPC.) 26599 Added hooks for writing the current CodeBlock* on function entry and 26600 after a function call, for the sake of the CodeBlock sampler. Removed 26601 obsolete hook for clearing the current sample inside op_end. Also removed 26602 the custom enum used to differentiate flavors of op_call, since the 26603 OpcodeID enum works just as well.

up repatch info, bug #21727. 26891 26892 When repatching JIT code to optimize we look up records providing information about 26893 the generated code (also used to track recsources used in linking to be later released). 26894 The lookup was being performed using a linear scan of all such records. 26895 26896 (1) Split up the different types of reptach information. This means we can search them 26897 separately, and in some cases should reduce their size. 26898 (2) In the case of property accesses, search with a binary chop over the data. 26899 (3) In the case of calls, pass a pointer to the repatch info into the relink function. 26900 26901 * VM/CTI.cpp: 26902 (JSC::CTI::CTI): 26903 (JSC::CTI::compileOpCall): 26904 (JSC::CTI::privateCompileMainPass): 26905 (JSC::CTI::privateCompileSlowCases): 26906 (JSC::CTI::privateCompile): 26907 (JSC::CTI::unlinkCall): 26908 (JSC::CTI::linkCall): 26909 * VM/CTI.h: 26910 * VM/CodeBlock.cpp: 26911 (JSC::CodeBlock::dump): 26912 (JSC::CodeBlock::~CodeBlock): 26913 (JSC::CodeBlock::unlinkCallers): 26914 (JSC::CodeBlock::derefStructureIDs): 26915 * VM/CodeBlock.h: 26916 (JSC::StructureStubInfo::StructureStubInfo): 26917 (JSC::CallLinkInfo::CallLinkInfo): 26918 (JSC::CallLinkInfo::setUnlinked): 26919 (JSC::CallLinkInfo::isLinked): 26920 (JSC::getStructureStubInfoReturnLocation): 26921 (JSC::binaryChop): 26922 (JSC::CodeBlock::addCaller): 26923 (JSC::CodeBlock::getStubInfo): 26924 * VM/CodeGenerator.cpp: 26925 (JSC::CodeGenerator::emitResolve): 26926 (JSC::CodeGenerator::emitGetById): 26927 (JSC::CodeGenerator::emitPutById): 26928 (JSC::CodeGenerator::emitCall): 26929 (JSC::CodeGenerator::emitConstruct): 26930 * VM/Machine.cpp: 26931 (JSC::Machine::cti_vm_lazyLinkCall): 26932 26933 2008-10-23 Peter Kasting <pkasting (a] google.com> 26934 26935 Reviewed by Adam Roben. 26936 26937 https://bugs.webkit.org/show_bug.cgi?id=21833 26938 Place JavaScript Debugger hooks under #if ENABLE(JAVASCRIPT_DEBUGGER). 26939 26940 * wtf/Platform.h: 26941 26942 2008-10-23 David Kilzer <ddkilzer (a] apple.com> 26943 26944 Bug 21831: Fix create_hash_table for Perl 5.10 26945 26946 <https://bugs.webkit.org/show_bug.cgi?id=21831> 26947 26948 Reviewed by Sam Weinig. 26949 26950 * kjs/create_hash_table: Escaped square brackets so that Perl 5.10 26951 doesn't try to use @nameEntries. 26952 26953 2008-10-23 Darin Adler <darin (a] apple.com> 26954 26955 -

We can currently only do so if the arity of the caller and callee 28536 match. The (optimized) setup for the call on the hot path is linked directly to 28537 the ctiCode for the callee, without indirection. 28538 28539 Two forms of the slow case of the call are generated, the first will be executed the 28540 first time the call is reached.

https://bugs.webkit.org/show_bug.cgi?id=21403 29833 Bug 21403: use new CallFrame class rather than Register* for call frame manipulation 29834 29835 Add CallFrame as a synonym for ExecState. Arguably, some day we should switch every 29836 client over to the new name. 29837 29838 Use CallFrame* consistently rather than Register* or ExecState* in low-level code such 29839 as Machine.cpp and CTI.cpp. Similarly, use callFrame rather than r as its name and use 29840 accessor functions to get at things in the frame. 29841 29842 Eliminate other uses of ExecState* that aren't needed, replacing in some cases with 29843 JSGlobalData* and in other cases eliminating them entirely. 29844 29845 * API/JSObjectRef.cpp: 29846 (JSObjectMakeFunctionWithCallback): 29847 (JSObjectMakeFunction): 29848

Removed emitDebugExceptionCheck -- no longer needed. 30760 (JSC::CTI::emitCall): Removed code to set ExecState::m_callFrame. 30761 (JSC::CTI::privateCompileMainPass): Removed code in catch to extract 30762 the exception from ExecState::m_exception; instead, the code that 30763 jumps into catch will make sure the exception is already in eax. 30764 * VM/CTI.h: Removed exec from the ctiTrampoline. Also removed the 30765 non-helpful "volatile". Temporarily left ARG_exec in as a synonym 30766 for ARG_r; I'll change that on a future cleanup pass when introducing 30767 more use of the CallFrame type. 30768 (JSC::CTI::execute): Removed the ExecState* argument. 30769 30770 * VM/ExceptionHelpers.cpp: 30771 (JSC::InterruptedExecutionError::InterruptedExecutionError): Take 30772 JSGlobalData* instead of ExecState*. 30773 (JSC::createInterruptedExecutionException): Ditto. 30774 * VM/ExceptionHelpers.h: Ditto. Also removed an unneeded include. 30775 30776 * VM/Machine.cpp: 30777 (JSC::slideRegisterWindowForCall): Removed the exec and 30778 exceptionValue arguments. Changed to return 0 when there's a stack 30779 overflow rather than using a separate exception argument to cut 30780 down on memory accesses in the calling convention. 30781 (JSC::Machine::unwindCallFrame): Removed the exec argument when 30782 constructing a DebuggerCallFrame. Also removed code to set 30783 ExecState::m_callFrame. 30784 (JSC::Machine::throwException): Removed the exec argument when 30785 construction a DebuggerCallFrame. 30786 (JSC::Machine::execute): Updated to use the register instead of 30787 ExecState and also removed various uses of ExecState. 30788 (JSC::Machine::debug): 30789 (JSC::Machine::privateExecute): Put globalData into a local 30790 variable so it can be used throughout the interpreter. Changed 30791 the VM_CHECK_EXCEPTION to get the exception in globalData instead 30792 of through ExecState. 30793 (JSC::Machine::retrieveLastCaller): Turn exec into a registers 30794 pointer by calling registers() instead of by getting m_callFrame. 30795 (JSC::Machine::callFrame): Ditto. 30796 Tweaked exception macros. Made new versions for when you know 30797 you have an exception. Get at global exception with ARG_globalData. 30798 Got rid of the need to pass in the return value type. 30799 (JSC::Machine::cti_op_add): Update to use new version of exception 30800 macros. 30801 (JSC::Machine::cti_op_pre_inc): Ditto. 30802 (JSC::Machine::cti_timeout_check): Ditto. 30803 (JSC::Machine::cti_op_instanceof): Ditto. 30804 (JSC::Machine::cti_op_new_func): Ditto. 30805 (JSC::Machine::cti_op_call_JSFunction): Optimized by using the 30806 ARG values directly instead of through local variables -- this gets 30807 rid of code that just shuffles things around in the stack frame. 30808 Also get rid of ExecState and update for the new way exceptions are 30809 handled in slideRegisterWindowForCall. 30810 (JSC::Machine::cti_vm_compile): Update to make exec out of r since 30811 they are both the same thing now. 30812 (JSC::Machine::cti_op_call_NotJSFunction): Ditto. 30813 (JSC::Machine::cti_op_init_arguments): Ditto. 30814 (JSC::Machine::cti_op_resolve): Ditto. 30815 (JSC::Machine::cti_op_construct_JSConstruct): Ditto. 30816 (JSC::Machine::cti_op_construct_NotJSConstruct): Ditto. 30817 (JSC::Machine::cti_op_resolve_func): Ditto. 30818 (JSC::Machine::cti_op_put_by_val): Ditto. 30819 (JSC::Machine::cti_op_put_by_val_array): Ditto. 30820 (JSC::Machine::cti_op_resolve_skip): Ditto. 30821 (JSC::Machine::cti_op_resolve_global): Ditto. 30822 (JSC::Machine::cti_op_post_inc): Ditto. 30823 (JSC::Machine::cti_op_resolve_with_base): Ditto. 30824 (JSC::Machine::cti_op_post_dec): Ditto. 30825 (JSC::Machine::cti_op_call_eval): Ditto. 30826 (JSC::Machine::cti_op_throw): Ditto.

Also added a typedef to 30845 the future name for this class, which is CallFrame. It's just a 30846 Register* that knows it's a pointer at a call frame. The new class 30847 can't be constructed or copied. Changed all functions to use 30848 the this pointer instead of m_callFrame. Changed exception-related 30849 functions to access an exception in JSGlobalData. Removed functions 30850 used by CTI to pass the return address to the throw machinery -- 30851 this is now done directly with a global in the global data. 30852 30853 * kjs/FunctionPrototype.cpp: 30854 (JSC::functionProtoFuncToString): Pass globalData instead of exec. 30855 30856 * kjs/InternalFunction.cpp: 30857 (JSC::InternalFunction::name): Take globalData instead of exec. 30858 * kjs/InternalFunction.h: Ditto. 30859 30860 * kjs/JSGlobalData.cpp: Initialize the new exception global to 0. 30861 * kjs/JSGlobalData.h: Declare two new globals.

When 'arguments' may have been assigned a new value, 31711 we use a new local variable that is initialized with 'arguments'. Since 31712 a function parameter named 'arguments' may overwrite the value of 31713 'arguments', we also need to be careful to look up 'arguments' in the 31714 symbol table, so we get the parameter named 'arguments' instead of the 31715 local variable that we have added for holding the 'arguments' object. 31716 31717 This is a 19.1% win on the V8 Raytrace benchmark using the SunSpider 31718 harness, and a 20.7% win using the V8 harness.

This change is based on the observation 32350 that if the result of certain operations is a JSNumberCell and is consumed by a subsequent 32351 operation that would produce a JSNumberCell, we can reuse the object rather than allocating 32352 a fresh one. E.g. given the expression ((a * b) * c), we can statically determine that 32353 (a * b) will have a numeric result (or else it will have thrown an exception), so the result 32354 will either be a JSNumberCell or a JSImmediate. 32355 32356 This patch changes three areas of JSC: 32357 * The AST now tracks type information about the result of each node. 32358 * This information is consumed in bytecode compilation, and certain bytecode operations 32359 now carry the statically determined type information about their operands. 32360 * CTI uses the information in a number of fashions: 32361 * Where an operand to certain arithmetic operations is reusable, it will plant code 32362 to try to perform the operation in JIT code & reuse the cell, where appropriate. 32363 * Where it can be statically determined that an operand can only be numeric (typically 32364 the result of another arithmetic operation) the code will not redundantly check that 32365 the JSCell is a JSNumberCell. 32366 * Where either of the operands to an add are non-numeric do not plant an optimized 32367 arithmetic code path, just call straight out to the C function. 32368 32369 +6% Sunspider (10% progression on 3D, 16% progression on math, 60% progression on access-nbody), 32370 +1% v8-tests (improvements in raytrace & crypto) 32371 32372 * VM/CTI.cpp: Add optimized code generation with reuse of temporary JSNumberCells. 32373 * VM/CTI.h: 32374 * kjs/JSNumberCell.h: 32375 * masm/X86Assembler.h: 32376 32377 * VM/CodeBlock.cpp: Add type information to specific bytecodes. 32378 * VM/CodeGenerator.cpp: 32379 * VM/CodeGenerator.h: 32380 * VM/Machine.cpp: 32381 32382 * kjs/nodes.cpp: Track static type information for nodes. 32383 * kjs/nodes.h: 32384 * kjs/ResultDescriptor.h: (Added) 32385 * JavaScriptCore.xcodeproj/project.pbxproj: 32386 32387 2008-09-26 Yichao Yin <yichao.yin (a] torchmobile.com.cn> 32388 32389 Reviewed by George Staikos, Maciej Stachowiak. 32390 32391 Add utility functions needed for upcoming WML code. 32392 32393 * wtf/ASCIICType.h: 32394 (WTF::isASCIIPrintable): 32395 32396 2008-09-26 Geoffrey Garen <ggaren (a] apple.com> 32397 32398 Reviewed by Darin Adler. 32399 32400 Reverted the part of r36614 that used static data because static data 32401 is not thread-safe. 32402 32403 2008-09-26 Geoffrey Garen <ggaren (a] apple.com> 32404 32405 Reviewed by Maciej Stachowiak. 32406 32407 Removed dynamic check for whether the callee needs an activation object. 32408 Replaced with callee code to create the activation object. 32409 32410 0.5% speedup on SunSpider. 32411 No change on v8 benchmark.

It is triggered 32649 by synchronous creation of a new global object from JS. The new 32650 global object resets the timer state in this execution group's 32651 Machine, taking timerCheckCount to 0. Then when JS returns the 32652 timerCheckCount is decremented making it non-zero. The next time 32653 we execute JS we will start the timeout counter, however the non-zero 32654 timeoutCheckCount means we don't reset the timer information. This 32655 means that the timeout check is now checking the cumulative time 32656 since the creation of the global object rather than the time since 32657 JS was last entered. At this point the slow script dialog is guaranteed 32658 to eventually be displayed incorrectly unless a page is loaded 32659 asynchronously (which will reset everything into a sane state). 32660 32661 The fix for this is rather trivial -- the JSGlobalObject constructor 32662 should not be resetting the machine timer state. 32663 32664 * VM/Machine.cpp: 32665 (JSC::Machine::Machine): 32666 Now that we can't rely on the GlobalObject initialising the timeout 32667 state, we do it in the Machine constructor. 32668 32669 * VM/Machine.h: 32670 (JSC::Machine::stopTimeoutCheck): 32671 Add assertions to guard against this happening. 32672 32673 * kjs/JSGlobalObject.cpp: 32674 (JSC::JSGlobalObject::init): 32675 Don't reset the timeout state. 32676 32677 2008-09-23 Geoffrey Garen <ggaren (a] apple.com> 32678 32679 Reviewed by Oliver Hunt. 32680 32681 Fixed https://bugs.webkit.org/show_bug.cgi?id=21038 | <rdar://problem/6240812> 32682 Uncaught exceptions in regex replace callbacks crash webkit 32683 32684 This was a combination of two problems: 32685 32686 (1) the replace function would continue execution after an exception 32687 had been thrown. 32688 32689 (2) In some cases, the Machine would return 0 in the case of an exception, 32690 despite the fact that a few clients dereference the Machine's return 32691 value without first checking for an exception. 32692 32693 * VM/Machine.cpp: 32694 (JSC::Machine::execute): 32695 32696 ^ Return jsNull() instead of 0 in the case of an exception, since some 32697 clients depend on using our return value. 32698 32699 ^ ASSERT that execution does not continue after an exception has been 32700 thrown, to help catch problems like this in the future. 32701 32702 * kjs/StringPrototype.cpp: 32703 (JSC::stringProtoFuncReplace): 32704 32705 ^ Stop execution if an exception has been thrown. 32706 32707 2008-09-23 Geoffrey Garen <ggaren (a] apple.com> 32708 32709 Try to fix the windows build. 32710 32711 * VM/CTI.cpp: 32712 (JSC::CTI::compileOpCall): 32713 (JSC::CTI::privateCompileMainPass): 32714 32715 2008-09-23 Alp Toker <alp (a] nuanti.com> 32716 32717 Build fix. 32718 32719 * VM/CTI.h: 32720 32721 2008-09-23 Geoffrey Garen <ggaren (a] apple.com> 32722 32723 Reviewed by Darin Adler. 32724 32725 * wtf/Platform.h: Removed duplicate #if. 32726 32727 2008-09-23 Geoffrey Garen <ggaren (a] apple.com> 32728 32729 Reviewed by Darin Adler. 32730 32731 Changed the layout of the call frame from 32732 32733 { header, parameters, locals | constants, temporaries } 32734 32735 to 32736 32737 { parameters, header | locals, constants, temporaries } 32738 32739 This simplifies function entry+exit, and enables a number of future 32740 optimizations. 32741 32742 13.5% speedup on empty call benchmark for bytecode; 23.6% speedup on 32743 empty call benchmark for CTI. 32744 32745 SunSpider says no change.

Thus we 35180 enable StructureIDs to handle this quirk for primitives. 35181 35182 Everything else should be straightforward. 35183 35184 * VM/CTI.cpp: 35185 (JSC::CTI::privateCompileGetByIdProto): 35186 (JSC::CTI::privateCompileGetByIdChain): 35187 * VM/CTI.h: 35188 (JSC::CTI::compileGetByIdProto): 35189 (JSC::CTI::compileGetByIdChain): 35190 * VM/JSPropertyNameIterator.h: 35191 (JSC::JSPropertyNameIterator::JSPropertyNameIterator): 35192 * VM/Machine.cpp: 35193 (JSC::Machine::Machine): 35194 (JSC::cachePrototypeChain): 35195 (JSC::Machine::tryCachePutByID): 35196 (JSC::Machine::tryCacheGetByID): 35197 (JSC::Machine::privateExecute): 35198 (JSC::Machine::tryCTICachePutByID): 35199 (JSC::Machine::tryCTICacheGetByID): 35200 * kjs/GetterSetter.h: 35201 (JSC::GetterSetter::GetterSetter): 35202 * kjs/JSCell.h: 35203 * kjs/JSGlobalData.cpp: 35204 (JSC::JSGlobalData::JSGlobalData): 35205 * kjs/JSGlobalData.h: 35206 * kjs/JSGlobalObject.h: 35207 (JSC::StructureID::prototypeForLookup): 35208 * kjs/JSNumberCell.h: 35209 (JSC::JSNumberCell::JSNumberCell): 35210 (JSC::jsNumberCell): 35211 * kjs/JSObject.h: 35212 (JSC::JSObject::prototype): 35213 * kjs/JSString.cpp: 35214 (JSC::jsString): 35215 (JSC::jsSubstring): 35216 (JSC::jsOwnedString): 35217 * kjs/JSString.h: 35218 (JSC::JSString::JSString): 35219 (JSC::JSString::): 35220 (JSC::jsSingleCharacterString): 35221 (JSC::jsSingleCharacterSubstring): 35222 (JSC::jsNontrivialString): 35223 * kjs/SmallStrings.cpp: 35224 (JSC::SmallStrings::createEmptyString): 35225 (JSC::SmallStrings::createSingleCharacterString): 35226 * kjs/StructureID.cpp: 35227 (JSC::StructureID::StructureID): 35228 (JSC::StructureID::addPropertyTransition): 35229 (JSC::StructureID::getterSetterTransition): 35230 (JSC::StructureIDChain::StructureIDChain): 35231 * kjs/StructureID.h: 35232 (JSC::StructureID::create): 35233 (JSC::StructureID::storedPrototype): 35234 35235 2008-09-09 Joerg Bornemann <joerg.bornemann (a] trolltech.com> 35236 35237 Reviewed by Sam Weinig. 35238 35239 https://bugs.webkit.org/show_bug.cgi?id=20746 35240 35241 Added WINCE platform macro. 35242 35243 * wtf/Platform.h: 35244 35245 2008-09-09 Sam Weinig <sam (a] webkit.org> 35246 35247 Reviewed by Mark Rowe. 35248 35249 Remove unnecessary override of getOffset. 35250 35251 Sunspider reports this as a .6% progression. 35252 35253 * JavaScriptCore.exp: 35254 * kjs/JSObject.h: 35255 (JSC::JSObject::getDirectLocation): 35256 (JSC::JSObject::getOwnPropertySlotForWrite): 35257 (JSC::JSObject::putDirect): 35258 * kjs/PropertyMap.cpp: 35259 * kjs/PropertyMap.h: 35260 35261 2008-09-09 Cameron Zwarich <cwzwarich (a] uwaterloo.ca> 35262 35263 Reviewed by Maciej Stachowiak. 35264 35265 Bug 20759: Remove MacroAssembler 35266 <https://bugs.webkit.org/show_bug.cgi?id=20759> 35267 35268 Remove MacroAssembler and move its functionality to X86Assembler. 35269 35270 * JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.vcproj: 35271 * JavaScriptCore.xcodeproj/project.pbxproj: 35272 * VM/CTI.cpp: 35273 (JSC::CTI::emitGetArg): 35274 (JSC::CTI::emitGetPutArg): 35275 (JSC::CTI::emitPutArg): 35276 (JSC::CTI::emitPutCTIParam): 35277 (JSC::CTI::emitGetCTIParam): 35278 (JSC::CTI::emitPutToCallFrameHeader): 35279 (JSC::CTI::emitGetFromCallFrameHeader): 35280 (JSC::CTI::emitPutResult): 35281 (JSC::CTI::emitDebugExceptionCheck): 35282 (JSC::CTI::emitJumpSlowCaseIfNotImm): 35283 (JSC::CTI::emitJumpSlowCaseIfNotImms): 35284 (JSC::CTI::emitFastArithDeTagImmediate): 35285 (JSC::CTI::emitFastArithReTagImmediate): 35286 (JSC::CTI::emitFastArithPotentiallyReTagImmediate): 35287 (JSC::CTI::emitFastArithImmToInt): 35288 (JSC::CTI::emitFastArithIntToImmOrSlowCase): 35289 (JSC::CTI::emitFastArithIntToImmNoCheck): 35290 (JSC::CTI::compileOpCall): 35291 (JSC::CTI::emitSlowScriptCheck): 35292 (JSC::CTI::privateCompileMainPass): 35293 (JSC::CTI::privateCompileSlowCases): 35294 (JSC::CTI::privateCompile): 35295 (JSC::CTI::privateCompileGetByIdSelf): 35296 (JSC::CTI::privateCompileGetByIdProto): 35297 (JSC::CTI::privateCompileGetByIdChain): 35298 (JSC::CTI::privateCompilePutByIdReplace): 35299 (JSC::CTI::privateArrayLengthTrampoline): 35300 (JSC::CTI::privateStringLengthTrampoline): 35301 (JSC::CTI::compileRegExp): 35302 * VM/CTI.h: 35303 (JSC::CallRecord::CallRecord): 35304 (JSC::JmpTable::JmpTable): 35305 (JSC::SlowCaseEntry::SlowCaseEntry): 35306 (JSC::CTI::JSRInfo::JSRInfo): 35307 * masm/MacroAssembler.h: Removed. 35308 * masm/MacroAssemblerWin.cpp: Removed. 35309 * masm/X86Assembler.h: 35310 (JSC::X86Assembler::emitConvertToFastCall): 35311 (JSC::X86Assembler::emitRestoreArgumentReference): 35312 * wrec/WREC.h: 35313 (JSC::WRECGenerator::WRECGenerator): 35314 (JSC::WRECParser::WRECParser): 35315 35316 2008-09-09 Sam Weinig <sam (a] webkit.org> 35317 35318 Reviewed by Cameron Zwarich. 35319 35320 Don't waste the first item in the PropertyStorage. 35321 35322 -

SFX behaves slightly differently under MSVC, specifically it 36423 stores the base argument address for the cti_op_* functions in the first 36424 argument, and then does the required stack manipulation through that pointer. 36425 This is necessary as MSVC's optimisations assume they have complete control 36426 of the stack, and periodically elide our stack manipulations, or move 36427 values in unexpected ways. MSVC also frequently produces tail calls which may 36428 clobber the first argument, so the MSVC path is slightly less efficient due 36429 to the need to restore it. 36430 36431 * JavaScriptCore.xcodeproj/project.pbxproj: 36432 * VM/CTI.cpp: 36433 (KJS::): 36434 (KJS::CTI::compileOpCall): 36435 (KJS::CTI::privateCompileMainPass): 36436 (KJS::CTI::privateCompileSlowCases): 36437 * VM/CTI.h: 36438 * VM/Machine.cpp: 36439 * VM/Machine.h: 36440 * masm/MacroAssembler.h: 36441 (KJS::MacroAssembler::emitConvertToFastCall): 36442 * masm/MacroAssemblerIA32GCC.cpp: Removed. 36443 For performance reasons we need these no-op functions to be inlined. 36444 36445 * masm/MacroAssemblerWin.cpp: 36446 (KJS::MacroAssembler::emitRestoreArgumentReference): 36447 * wtf/Platform.h: 36448 36449 2008-09-05 Geoffrey Garen <ggaren (a] apple.com> 36450 36451 Reviewed by Maciej Stachowiak, or maybe the other way around. 36452 36453 Added the ability to coalesce JITCode buffer grow operations by first 36454 growing the buffer and then executing unchecked puts to it. 36455 36456 About a 2% speedup on date-format-tofte. 36457 36458 * VM/CTI.cpp: 36459 (KJS::CTI::compileOpCall): 36460 * masm/IA32MacroAsm.h: 36461 (KJS::JITCodeBuffer::ensureSpace): 36462 (KJS::JITCodeBuffer::putByteUnchecked): 36463 (KJS::JITCodeBuffer::putByte): 36464 (KJS::JITCodeBuffer::putShortUnchecked): 36465 (KJS::JITCodeBuffer::putShort): 36466 (KJS::JITCodeBuffer::putIntUnchecked): 36467 (KJS::JITCodeBuffer::putInt): 36468 (KJS::IA32MacroAssembler::emitTestl_i32r): 36469 (KJS::IA32MacroAssembler::emitMovl_mr): 36470 (KJS::IA32MacroAssembler::emitMovl_rm): 36471 (KJS::IA32MacroAssembler::emitMovl_i32m): 36472 (KJS::IA32MacroAssembler::emitUnlinkedJe): 36473 (KJS::IA32MacroAssembler::emitModRm_rr): 36474 (KJS::IA32MacroAssembler::emitModRm_rr_Unchecked): 36475 (KJS::IA32MacroAssembler::emitModRm_rm_Unchecked): 36476 (KJS::IA32MacroAssembler::emitModRm_rm): 36477 (KJS::IA32MacroAssembler::emitModRm_opr): 36478 (KJS::IA32MacroAssembler::emitModRm_opr_Unchecked): 36479 (KJS::IA32MacroAssembler::emitModRm_opm_Unchecked): 36480 36481 2008-09-05 Mark Rowe <mrowe (a] apple.com> 36482 36483 Reviewed by Sam Weinig. 36484 36485 Disable WREC and CTI on platforms that we have not yet had a chance to test with. 36486 36487 * wtf/Platform.h: 36488 36489 2008-09-05 Geoffrey Garen <ggaren (a] apple.com> 36490 36491 Reviewed by Sam Weinig. 36492 36493 Use jo instead of a mask compare when fetching array.length and 36494 string.length. 4% speedup on array.length / string.length torture 36495 test. 36496 36497 * VM/CTI.cpp: 36498 (KJS::CTI::privateArrayLengthTrampoline): 36499 (KJS::CTI::privateStringLengthTrampoline): 36500 36501 2008-09-05 Geoffrey Garen <ggaren (a] apple.com> 36502 36503 Reviewed by Sam Weinig. 36504 36505 Removed a CTI compilation pass by recording labels during bytecode 36506 generation.

This patch takes the exception checking 37041 back of the hot path. When an exception occurs in a Machine::cti* 37042 method, the return address to JIT code is recorded, and is then 37043 overwritten with a pointer to a trampoline routine. When the method 37044 returns the trampoline will cause the cti_vm_throw method to be invoked. 37045 37046 cti_vm_throw uses the return address preserved above, to discover the 37047 vPC of the bytecode that raised the exception (using a map build during 37048 translation). From the VPC of the faulting bytecode the vPC of a catch 37049 routine may be discovered (unwinding the stack where necesary), and then 37050 a bytecode address for the catch routine is looked up. Final cti_vm_throw 37051 overwrites its return address to JIT code again, to trampoline directly 37052 to the catch routine. 37053 37054 cti_op_throw is handled in a similar fashion. 37055 37056 *

This avoids adding a PIC branch for 38929 the normal case when there is no failure. 38930 (KJS::UString::expandPreCapacity): Ditto. 38931 (KJS::UString::UString): Ditto. 38932 (KJS::concatenate): Refactored the concatenation constructor into this 38933 separate function. Calling the concatenation constructor was leading to 38934 an extra branch because of the in-charge vs. not-in-charge versions not 38935 both being inlined, and this was showing up as nearly 1% on Shark. Also 38936 added a special case for when the second string is a single character, 38937 since it's a common idiom to build up a string that way and we can do 38938 things much more quickly, without involving memcpy for example. Also 38939 adopted the non-inline function, nullRep, for the same reason given for 38940 makeNull above. 38941 (KJS::UString::append): Adopted makeNull for failure cases. 38942 (KJS::UString::operator=): Ditto. 38943 (KJS::UString::toDouble): Added a special case for converting single 38944 character strings to numbers. We're doing this a ton of times while 38945 running the base64 test. 38946 (KJS::operator==): Added special cases so we can compare single-character 38947 strings without calling memcmp.
