[ES6] Arrow function syntax. Arrow function specific features. Lexical bind "arguments" https://bugs.webkit.org/show_bug.cgi?id=145132 Patch by Skachkov Oleksandr <gskachkov@gmail.com> on 2016-01-25 Reviewed by Saam Barati. Source/JavaScriptCore: Added support of ES6 arrow function specific feature, lexical bind of arguments. http://www.ecma-international.org/ecma-262/6.0/#sec-arrow-function-definitions-runtime-semantics-evaluation 'arguments' variable in arrow function must resolve to a binding in a lexically enclosing environment. In srict mode it points to arguments object, and in non-stric mode it points to arguments object or varible with name 'arguments' if it was declared. * bytecompiler/BytecodeGenerator.cpp: (JSC::BytecodeGenerator::BytecodeGenerator): * parser/Parser.h: (JSC::Scope::Scope): (JSC::Scope::setSourceParseMode): (JSC::Scope::isArrowFunction): (JSC::Scope::collectFreeVariables): (JSC::Scope::setIsArrowFunction): * tests/es6.yaml: * tests/stress/arrowfunction-lexical-bind-arguments-non-strict-1.js: Added. * tests/stress/arrowfunction-lexical-bind-arguments-non-strict-2.js: Added. * tests/stress/arrowfunction-lexical-bind-arguments-strict.js: Added.
