ES6: Allow duplicate property names https://bugs.webkit.org/show_bug.cgi?id=142895 Patch by Joseph Pecoraro <pecoraro@apple.com> on 2015-05-13 Reviewed by Geoffrey Garen. Source/JavaScriptCore: Introduce new `op_put_getter_by_id` and `op_put_setter_by_id` opcodes that will define a single getter or setter property on an object. The existing `op_put_getter_setter` opcode is still preferred for putting both a getter and setter at the same time but cannot be used for putting an individual getter or setter which is needed in some cases. Add a new slow path when generating bytecodes for a property list with computed properties, as computed properties are the only time the list of properties cannot be determined statically. * bytecompiler/NodesCodegen.cpp: (JSC::PropertyListNode::emitBytecode): - fast path for all constant properties - slow but paired getter/setter path if there are no computed properties - slow path, individual put operation for every property, if there are computed properties * parser/Nodes.h: Distinguish a Computed property from a Constant property. * parser/Parser.cpp: (JSC::Parser<LexerType>::parseProperty): (JSC::Parser<LexerType>::parsePropertyMethod): Distingish Computed and Constant properties. (JSC::Parser<LexerType>::parseObjectLiteral): When we drop into strict mode it is because we saw a getter or setter, so be more explicit. (JSC::Parser<LexerType>::parseStrictObjectLiteral): Eliminate duplicate property syntax error exception. * parser/SyntaxChecker.h: (JSC::SyntaxChecker::getName): * parser/ASTBuilder.h: (JSC::ASTBuilder::getName): Deleted. No longer used. * runtime/JSObject.h: (JSC::JSObject::putDirectInternal): When updating a property. If the Accessor attribute changed update the Structure. * runtime/JSObject.cpp: (JSC::JSObject::putGetter): (JSC::JSObject::putSetter): Called by the opcodes, just perform the same operation that __defineGetter__ or __defineSetter__ would do. (JSC::JSObject::putDirectNonIndexAccessor): This transition is now handled in putDirectInternal. * runtime/Structure.h: Add needed export. * bytecode/BytecodeList.json: * bytecode/BytecodeUseDef.h: (JSC::computeUsesForBytecodeOffset): (JSC::computeDefsForBytecodeOffset): * bytecode/CodeBlock.cpp: (JSC::CodeBlock::dumpBytecode): * bytecompiler/BytecodeGenerator.cpp: (JSC::BytecodeGenerator::emitPutGetterById): (JSC::BytecodeGenerator::emitPutSetterById): * bytecompiler/BytecodeGenerator.h: * jit/JIT.cpp: (JSC::JIT::privateCompileMainPass): * jit/JIT.h: * jit/JITInlines.h: (JSC::JIT::callOperation): * jit/JITOperations.cpp: * jit/JITOperations.h: * jit/JITPropertyAccess.cpp: (JSC::JIT::emit_op_put_getter_by_id): (JSC::JIT::emit_op_put_setter_by_id): * jit/JITPropertyAccess32_64.cpp: (JSC::JIT::emit_op_put_getter_by_id): (JSC::JIT::emit_op_put_setter_by_id): * llint/LLIntSlowPaths.cpp: (JSC::LLInt::LLINT_SLOW_PATH_DECL): * llint/LLIntSlowPaths.h: * llint/LowLevelInterpreter.asm: New bytecodes. Modelled after existing op_put_getter_setter. LayoutTests: * js/object-literal-duplicate-properties-expected.txt: Added. * js/object-literal-duplicate-properties.html: Added. * js/script-tests/object-literal-duplicate-properties.js: Added. Include a new test all about testing duplicate property names and their expected cascading results. * ietestcenter/Javascript/11.1.5_4-4-b-1-expected.txt: * ietestcenter/Javascript/11.1.5_4-4-b-2-expected.txt: * ietestcenter/Javascript/11.1.5_4-4-c-1-expected.txt: * ietestcenter/Javascript/11.1.5_4-4-c-2-expected.txt: * ietestcenter/Javascript/11.1.5_4-4-d-1-expected.txt: * ietestcenter/Javascript/11.1.5_4-4-d-2-expected.txt: * ietestcenter/Javascript/11.1.5_4-4-d-3-expected.txt: * ietestcenter/Javascript/11.1.5_4-4-d-4-expected.txt: ES5 behavior for duplciate properties has changed. * js/mozilla/strict/11.1.5-expected.txt: * js/object-literal-syntax-expected.txt: * js/script-tests/object-literal-syntax.js: Update other tests and values now that duplicate properties are allowed, and their cascade order behaves correctly.
