or ConstructTypeNone now get a global object in their constructor - and store that in their first anonymous slot. We add a new type - JSObjectWithGlobalObject to allow us to share this logic as much - as possible, however some objects have specific inheritance - requirements so we can't just use it universally. - - To enforce this requirement JSValue::getCallData and getConstructData - make use of a new "isValidCallee" function to assert that any object - that returns a value other than CallType/ConstructTypeNone has a - global object in anonymous slot 0. - - In order to ensure that static function slots are converted into - function objects with the correct global object, all prototype objects - and other classes with static function slots also gain a global object - reference. Happily this fixes the long standing issue where host - function objects get a prototype from the lexical global object of the - first function that calls them, instead of the global object that they - are defined on. - - * API/JSCallbackConstructor.cpp: - (JSC::JSCallbackConstructor::JSCallbackConstructor): - * API/JSCallbackConstructor.h: - * API/JSCallbackFunction.cpp: - (JSC::JSCallbackFunction::JSCallbackFunction): -

In the interpreter the call - passes the return value register id into the callee via the callee callframe, - and the callee is responsible for writing the result back into its callers - register file after it has restored the parents callframe pointer, but before - returning. - - Instead, move the task of writing the call result to the register file into a - new opcode (op_call_put_result), and after returning the callee should leave - the return value in a canonical location. In the case of the interpreter, - this canonical location is a local variable in privateExecute - (functionReturnValue), in the case of the JIT this is the normal return value - registers (regT0, or regT1:regT0 in JSVALUE32_64). op_call_put_result stores - the result from the canonical location to the registerfile. - - In addition to unifying JIT & interpreter behaviour this change allows us to - remove a slot from the callframe, omit the write of the result where the - return value from the call is not used, and provides a 2% speedup on sunspider - in the interpreter. - - * bytecode/CodeBlock.cpp: - (JSC::CodeBlock::dump): - * bytecode/Opcode.h: - * bytecompiler/BytecodeGenerator.cpp: -

UString's method - cannot support UStringImpl's behaviour directly, since it returns an object rather than a - pointer. - - remove UString::createUninitialized(), replace with calls to UStringImpl::createUninitialized() - - create a UStringImpl::tryCreateUninitialized() form UStringImpl::createUninitialized(), - with current behaviour, make createUninitialized() crash on failure to allocate. - - make cases in JSC that do not check the result call createUninitialized(), and cases that do - check call tryCreateUninitialized(). - - Rename computedHash() to existingHash(), to bring this in line wih WebCore::StringImpl. - - * API/JSClassRef.cpp: - (OpaqueJSClassContextData::OpaqueJSClassContextData): - * JavaScriptCore.exp: - * runtime/ArrayPrototype.cpp: - (JSC::arrayProtoFuncToString): - * runtime/Identifier.cpp: - (JSC::CStringTranslator::translate): - (JSC::UCharBufferTranslator::translate): - * runtime/JSString.cpp: - (JSC::JSString::resolveRope): - * runtime/Lookup.cpp: - (JSC::HashTable::createTable): - * runtime/Lookup.h: - (JSC::HashTable::entry): - * runtime/StringBuilder.h: - (JSC::StringBuilder::release): - * runtime/StringConstructor.cpp: - (JSC::stringFromCharCodeSlowCase): - * runtime/StringPrototype.cpp: - (JSC::substituteBackreferencesSlow): - (JSC::stringProtoFuncToLowerCase): - (JSC::stringProtoFuncToUpperCase): - (JSC::stringProtoFuncFontsize): - (JSC::stringProtoFuncLink): - * runtime/Structure.cpp: - (JSC::Structure::despecifyDictionaryFunction): - (JSC::Structure::get): - (JSC::Structure::despecifyFunction): - (JSC::Structure::put): - (JSC::Structure::remove): - (JSC::Structure::insertIntoPropertyMapHashTable): - (JSC::Structure::checkConsistency): - * runtime/Structure.h: - (JSC::Structure::get): - * runtime/StructureTransitionTable.h: - (JSC::StructureTransitionTableHash::hash): - * runtime/UString.cpp: - (JSC::createRep): - (JSC::UString::UString): - (JSC::UString::spliceSubstringsWithSeparators): - (JSC::UString::replaceRange): - (JSC::UString::operator=): - * runtime/UString.h: - (JSC::UString::adopt): - (JSC::IdentifierRepHash::hash): - (JSC::makeString): - * runtime/UStringImpl.h: - (JSC::UStringImpl::adopt): - (JSC::UStringImpl::create): - (JSC::UStringImpl::createUninitialized): - (JSC::UStringImpl::tryCreateUninitialized): - (JSC::UStringImpl::existingHash): - -2010-01-13 Kent Hansen <kent.hansen@nokia.com> - - Reviewed by Oliver Hunt. - - JSON.stringify and JSON.parse needlessly process properties in the prototype chain - https://bugs.webkit.org/show_bug.cgi?id=33053 - - * runtime/JSONObject.cpp: - (JSC::Stringifier::Holder::appendNextProperty): - (JSC::Walker::walk): - -2010-01-13 Gavin Barraclough <barraclough@apple.com> - - Reviewed by NOBODY (buildfix). - - * JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.def: - -2010-01-13 Alexey Proskuryakov <ap@apple.com> - - Reviewed by Darin Adler. - - https://bugs.webkit.org/show_bug.cgi?id=33641 - Assertion failure in Lexer.cpp if input stream ends while in string escape - - Test: fast/js/end-in-string-escape.html - - * parser/Lexer.cpp: (JSC::Lexer::lex): Bail out quickly on end of stream, not giving the - assertion a chance to fire. - -2010-01-13 Gavin Barraclough <barraclough@apple.com> - - Reviewed by NOBODY (buildfix). - - * JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.def: - -2010-01-13 Gavin Barraclough <barraclough@apple.com> - - Rubber stamped by Sam Weinig & Darin Adler. - - Three quick fixes to UStringImpl. - - The destroy() method can be switched back to a normal destructor; since we've switched - the way we protect static strings to be using an odd ref-count the destroy() won't abort. - - The cost() calculation logic was wrong.

But now it's no longer necessary for the first - clause to jump there so jump fusion is not blocked. - - d) We avoid generating excess mov statements in some cases. - - As a concrete example this source: - - if (!((x < q && y < q) || (t < q && z < q))) { - // ... - } - - Used to generate this bytecode: - - [ 34] less r1, r-15, r-19 - [ 38] jfalse r1, 7(->45) - [ 41] less r1, r-16, r-19 - [ 45] jtrue r1, 14(->59) - [ 48] less r1, r-17, r-19 - [ 52] jfalse r1, 7(->59) - [ 55] less r1, r-18, r-19 - [ 59] jtrue r1, 17(->76) - - And now generates this bytecode (also taking advantage of the second optimization below): - - [ 34] jnless r-15, r-19, 8(->42) - [ 38] jless r-16, r-19, 26(->64) - [ 42] jnless r-17, r-19, 8(->50) - [ 46] jless r-18, r-19, 18(->64) - - Note the jump fusion and the fact that there's less jump - indirection - three of the four jumps go straight to the target - clause instead of indirecting through another jump. - - 2) Implement jless opcode to take advantage of the above, since we'll now often generate - a less followed by a jtrue where fusion is not forbidden. - - * parser/Nodes.h: - (JSC::ExpressionNode::hasConditionContextCodegen): Helper function to determine - whether a node supports special conditional codegen.

Moreover, - since Qt resets all thread local values to 0 before the calling of the - appropriate destructors, we set back the pointer to its original value. - This is necessary because the get() method of the ThreadSpecific - object may be called during the exuction of the destructor. - - * wtf/ThreadSpecific.h: - (WTF::ThreadSpecific::Data::~Data): - (WTF::::~ThreadSpecific): - (WTF::::set): - (WTF::::destroy): - -2009-09-10 Oliver Hunt <oliver@apple.com> - - Reviewed by Geoff Garen. - - Allow anonymous storage inside JSObject - https://bugs.webkit.org/show_bug.cgi?id=29168 - - Add the concept of anonymous slots to Structures so that it is - possible to store references to values that need marking in the - standard JSObject storage buffer.
