[JSC] Add @throwXXXError bytecode intrinsic https://bugs.webkit.org/show_bug.cgi?id=162995 Reviewed by Saam Barati. Source/JavaScriptCore: Builtin JS code need to check arguments carefully since it is somewhat standard library for JS. So bunch of `throw new @TypeError("...")` exists while usual code does not have so many. However the above code bloats 32 instructions per site, enlarges the size of bytecodes of builtins, and prevent us from inlining. We should have a way to reduce this size. Fortunately, we already have such a opcode: op_throw_static_error. In this patch, 1. We extends op_throw_static_error to throw arbitrary errors. Previously, only TypeError and ReferenceError are allowed. We can embed ErrorType enum in op_throw_static_error to throw any types of errors. 2. We introduce several new bytecode intrinsics, `@throwTypeError("...")`, `@throwRangeError("...")`, and `@throwOutOfMemoryError()`. And use it inside builtin JS instead of `throw new @TypeError("...")` thingy. 3. DFG Node for throw_static_error is incorrectly named as "ThrowReferenceError". This patch renames it to "ThrowStaticError". * builtins/ArrayConstructor.js: * builtins/ArrayIteratorPrototype.js: (next): * builtins/ArrayPrototype.js: (values): (keys): (entries): (reduce): (reduceRight): (every): (forEach): (filter): (map): (some): (fill): (find): (findIndex): (includes): (sort): (concatSlowPath): (copyWithin): * builtins/DatePrototype.js: (toLocaleString.toDateTimeOptionsAnyAll): (toLocaleString): (toLocaleDateString.toDateTimeOptionsDateDate): (toLocaleDateString): (toLocaleTimeString.toDateTimeOptionsTimeTime): (toLocaleTimeString): * builtins/FunctionPrototype.js: (bind): * builtins/GeneratorPrototype.js: (globalPrivate.generatorResume): * builtins/GlobalOperations.js: (globalPrivate.speciesConstructor): * builtins/MapPrototype.js: (forEach): * builtins/ModuleLoaderPrototype.js: (provide): * builtins/ObjectConstructor.js: (values): (entries): (assign): * builtins/PromiseConstructor.js: (race): (reject): (resolve): * builtins/PromiseOperations.js: (globalPrivate.newPromiseCapability.executor): (globalPrivate.newPromiseCapability): (globalPrivate.initializePromise): * builtins/PromisePrototype.js: * builtins/ReflectObject.js: (apply): (deleteProperty): (has): * builtins/RegExpPrototype.js: (globalPrivate.regExpExec): (match): (replace): (search): (split): (intrinsic.RegExpTestIntrinsic.test): * builtins/SetPrototype.js: (forEach): * builtins/StringConstructor.js: (raw): * builtins/StringIteratorPrototype.js: (next): * builtins/StringPrototype.js: (match): (globalPrivate.repeatSlowPath): (repeat): (padStart): (padEnd): (intrinsic.StringPrototypeReplaceIntrinsic.replace): (localeCompare): (search): (split): * builtins/TypedArrayConstructor.js: (of): (from): * builtins/TypedArrayPrototype.js: (globalPrivate.typedArraySpeciesConstructor): (every): (find): (findIndex): (forEach): (some): (subarray): (reduce): (reduceRight): (map): (filter): * bytecode/BytecodeIntrinsicRegistry.h: * bytecode/CodeBlock.cpp: (JSC::CodeBlock::dumpBytecode): * bytecompiler/BytecodeGenerator.cpp: (JSC::BytecodeGenerator::emitThrowStaticError): (JSC::BytecodeGenerator::emitThrowReferenceError): (JSC::BytecodeGenerator::emitThrowTypeError): (JSC::BytecodeGenerator::emitThrowRangeError): (JSC::BytecodeGenerator::emitThrowOutOfMemoryError): (JSC::BytecodeGenerator::emitReadOnlyExceptionIfNeeded): * bytecompiler/BytecodeGenerator.h: * bytecompiler/NodesCodegen.cpp: (JSC::BytecodeIntrinsicNode::emit_intrinsic_throwTypeError): (JSC::BytecodeIntrinsicNode::emit_intrinsic_throwRangeError): (JSC::BytecodeIntrinsicNode::emit_intrinsic_throwOutOfMemoryError): * dfg/DFGAbstractInterpreterInlines.h: (JSC::DFG::AbstractInterpreter<AbstractStateType>::executeEffects): * dfg/DFGByteCodeParser.cpp: (JSC::DFG::ByteCodeParser::parseBlock): * dfg/DFGClobberize.h: (JSC::DFG::clobberize): * dfg/DFGDoesGC.cpp: (JSC::DFG::doesGC): * dfg/DFGFixupPhase.cpp: (JSC::DFG::FixupPhase::fixupNode): * dfg/DFGNodeType.h: * dfg/DFGPredictionPropagationPhase.cpp: * dfg/DFGSafeToExecute.h: (JSC::DFG::safeToExecute): * dfg/DFGSpeculativeJIT32_64.cpp: (JSC::DFG::SpeculativeJIT::compile): * dfg/DFGSpeculativeJIT64.cpp: (JSC::DFG::SpeculativeJIT::compile): * ftl/FTLCapabilities.cpp: (JSC::FTL::canCompile): * ftl/FTLLowerDFGToB3.cpp: (JSC::FTL::DFG::LowerDFGToB3::compileNode): * jit/JITOpcodes.cpp: (JSC::JIT::emit_op_throw_static_error): * jit/JITOpcodes32_64.cpp: (JSC::JIT::emit_op_throw_static_error): Deleted. * jit/JITOperations.cpp: * jit/JITOperations.h: * llint/LLIntSlowPaths.cpp: (JSC::LLInt::LLINT_SLOW_PATH_DECL): Deleted. * llint/LLIntSlowPaths.h: * llint/LowLevelInterpreter.asm: * runtime/CommonSlowPaths.cpp: (JSC::SLOW_PATH_DECL): * runtime/CommonSlowPaths.h: * runtime/Error.cpp: (JSC::createError): (WTF::printInternal): * runtime/Error.h: LayoutTests: * js/Object-assign-expected.txt: Canonical link: https://commits.webkit.org/180906@main git-svn-id: https://svn.webkit.org/repository/webkit/trunk@206853 268f45cc-cd09-0410-ab3c-d52691b4dbfc
