The only difference + between the classes is which flag (isIdentifier or inTable) is set. + Combine the two classes using a template predicated on which flag to use. + + New class AtomicStringTable created, containing all the goodness from + IdentifierTable & AtomicStringTable, expect for Identifier's literalTable, + which has been moved onto JSGlobalData. Removed duplicate string translator + classes. Renamed StringImpl's inTable flag to more explicit 'isAtomic', + and set this on the empty string (which matches Identifier behaviour, and + removes a redundant check for zero-length). + + * GNUmakefile.am: + * JavaScriptCore.gypi: + * JavaScriptCore.vcproj/WTF/WTF.vcproj: + * JavaScriptCore.xcodeproj/project.pbxproj: + * runtime/Identifier.cpp: + (JSC::createLiteralTable): + (JSC::deleteLiteralTable): + (JSC::Identifier::add): + (JSC::Identifier::addSlowCase): + * runtime/Identifier.h: + * runtime/JSGlobalData.cpp: + (JSC::JSGlobalData::JSGlobalData): + (JSC::JSGlobalData::~JSGlobalData): + * runtime/JSGlobalData.h: + * wtf/WTFThreadData.cpp: + (WTF::WTFThreadData::WTFThreadData): + (WTF::WTFThreadData::~WTFThreadData): + * wtf/WTFThreadData.h: + (WTF::WTFThreadData::atomicStringTable): + * wtf/text/AtomicString.cpp: + (WebCore::table): + (WebCore::operator==): + (WebCore::AtomicString::add): + (WebCore::AtomicString::find): + (WebCore::AtomicString::remove): + * wtf/text/AtomicStringTable.h: Added. + (WTF::CStringTranslator::hash): + (WTF::CStringTranslator::equal): + (WTF::CStringTranslator::translate): + (WTF::UCharBufferTranslator::hash): + (WTF::UCharBufferTranslator::equal): + (WTF::UCharBufferTranslator::translate): + (WTF::HashAndCharactersTranslator::hash): + (WTF::HashAndCharactersTranslator::equal): + (WTF::HashAndCharactersTranslator::translate): + (WTF::IdentifierOrAtomicStringTable::remove): + (WTF::::~IdentifierOrAtomicStringTable): + (WTF::::add): + (WTF::::find): + * wtf/text/StringImpl.cpp: + (WebCore::StringImpl::~StringImpl): + * wtf/text/StringImpl.h: + (WebCore::StringImpl::isAtomic): + (WebCore::StringImpl::setIsAtomic): + (WebCore::equal): + * wtf/text/StringImplBase.h: + (WTF::StringImplBase::StringImplBase): + +2010-04-22 Steve Block <steveblock@google.com> + + Reviewed by Adam Barth. + + Update Android to use isfinite, isinf, isnan and signbit from namespace std. + https://bugs.webkit.org/show_bug.cgi?id=37948 + + * wtf/MathExtras.h: + +2010-04-22 Jocelyn Turcotte <jocelyn.turcotte@nokia.com> + + Reviewed by Kenneth Rohde Christiansen. + + [Qt] Remove dependency of JSC to QtGui + https://bugs.webkit.org/show_bug.cgi?id=37867 + + The patch also make sure that hal.h is in the include path on Symbian. + The dependency to QtGui took care of that before. + + Patch by Thiago Macieira <thiago.macieira@nokia.com> + and Rohan McGovern <rohan.mcgovern@nokia.com> + + * JavaScriptCore.pri: + * JavaScriptCore.pro: + +2010-04-22 Jocelyn Turcotte <jocelyn.turcotte@nokia.com> + + Reviewed by Tor Arne Vestbø. + + [Qt] Corrects symbols visibility for JavaScriptCore. + + https://bugs.webkit.org/show_bug.cgi?id=37867 + + * JavaScriptCore.pro: + +2010-04-22 Gabor Loki <loki@webkit.org> + + Reviewed by Gavin Barraclough. + + Use BLX and BX to keep happy the return stack predictor above ARMv4 + https://bugs.webkit.org/show_bug.cgi?id=37862 + + Inspired by Jacob Bramley's patch from JaegerMonkey + + * assembler/ARMAssembler.cpp: + (JSC::ARMAssembler::executableCopy): + * assembler/ARMAssembler.h: + (JSC::ARMAssembler::): + (JSC::ARMAssembler::bx): + (JSC::ARMAssembler::blx): + (JSC::ARMAssembler::loadBranchTarget): + (JSC::ARMAssembler::jmp): + (JSC::ARMAssembler::getLdrImmAddress): + * assembler/MacroAssemblerARM.h: + (JSC::MacroAssemblerARM::jump): + (JSC::MacroAssemblerARM::nearCall): + (JSC::MacroAssemblerARM::call): + (JSC::MacroAssemblerARM::ret): + (JSC::MacroAssemblerARM::prepareCall): + (JSC::MacroAssemblerARM::call32): + +2010-04-21 Andy Estes <aestes@apple.com> + + Rubber stamped by Mark Rowe. + + Export WTF::deleteOwnedPtr(HFONT). + + * JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.def: + 2010-04-21 Gavin Barraclough <barraclough@apple.com> Rubber Stamped by Oliver Hunt. |
