https://bugs.webkit.org/show_bug.cgi?id=122566 Source/JavaScriptCore: Reviewed by Mark Rowe. The JSC project now builds a libllvmForJSC.dylib. If FTL is enabled, this gets copied into JavaScriptCore.framework/Versions/A/Libraries. JSC will load the dylib by finding it using NSBundle APIs and then doing dlopen(). That will only happen lazily, when something happens that requires LLVM. This mostly takes care of LLVM static initialization overhead by deferring it until it's really needed. This takes care of LLVM's exit-time destructors because inside libllvmForJSC.dylib, we override __cxa_atexit. * Configurations/JavaScriptCore.xcconfig: * Configurations/LLVMForJSC.xcconfig: Added. * JavaScriptCore.xcodeproj/project.pbxproj: * dfg/DFGPlan.cpp: (JSC::DFG::Plan::compileInThreadImpl): * disassembler/LLVMDisassembler.cpp: (JSC::tryToDisassembleWithLLVM): * ftl/FTLAbbreviatedTypes.h: * ftl/FTLAbbreviations.h: (JSC::FTL::voidType): (JSC::FTL::int1Type): (JSC::FTL::int8Type): (JSC::FTL::int16Type): (JSC::FTL::int32Type): (JSC::FTL::int64Type): (JSC::FTL::intPtrType): (JSC::FTL::floatType): (JSC::FTL::doubleType): (JSC::FTL::pointerType): (JSC::FTL::structType): (JSC::FTL::functionType): (JSC::FTL::typeOf): (JSC::FTL::mdKindID): (JSC::FTL::mdString): (JSC::FTL::mdNode): (JSC::FTL::setMetadata): (JSC::FTL::addFunction): (JSC::FTL::setLinkage): (JSC::FTL::setFunctionCallingConv): (JSC::FTL::getParam): (JSC::FTL::constInt): (JSC::FTL::constReal): (JSC::FTL::constIntToPtr): (JSC::FTL::constBitCast): (JSC::FTL::appendBasicBlock): (JSC::FTL::insertBasicBlock): (JSC::FTL::buildPhi): (JSC::FTL::addIncoming): (JSC::FTL::buildAlloca): (JSC::FTL::buildAdd): (JSC::FTL::buildSub): (JSC::FTL::buildMul): (JSC::FTL::buildDiv): (JSC::FTL::buildRem): (JSC::FTL::buildNeg): (JSC::FTL::buildFAdd): (JSC::FTL::buildFSub): (JSC::FTL::buildFMul): (JSC::FTL::buildFDiv): (JSC::FTL::buildFRem): (JSC::FTL::buildFNeg): (JSC::FTL::buildAnd): (JSC::FTL::buildOr): (JSC::FTL::buildXor): (JSC::FTL::buildShl): (JSC::FTL::buildAShr): (JSC::FTL::buildLShr): (JSC::FTL::buildNot): (JSC::FTL::buildLoad): (JSC::FTL::buildStore): (JSC::FTL::buildSExt): (JSC::FTL::buildZExt): (JSC::FTL::buildFPToSI): (JSC::FTL::buildFPToUI): (JSC::FTL::buildSIToFP): (JSC::FTL::buildUIToFP): (JSC::FTL::buildIntCast): (JSC::FTL::buildFPCast): (JSC::FTL::buildIntToPtr): (JSC::FTL::buildPtrToInt): (JSC::FTL::buildBitCast): (JSC::FTL::buildICmp): (JSC::FTL::buildFCmp): (JSC::FTL::buildCall): (JSC::FTL::setTailCall): (JSC::FTL::buildExtractValue): (JSC::FTL::buildSelect): (JSC::FTL::buildBr): (JSC::FTL::buildCondBr): (JSC::FTL::buildSwitch): (JSC::FTL::addCase): (JSC::FTL::buildRet): (JSC::FTL::buildUnreachable): (JSC::FTL::dumpModule): (JSC::FTL::verifyModule): * ftl/FTLCompile.cpp: (JSC::FTL::compile): * ftl/FTLFail.cpp: (JSC::FTL::fail): * ftl/FTLJITCode.h: * ftl/FTLJITFinalizer.h: * ftl/FTLLink.cpp: * ftl/FTLLowerDFGToLLVM.cpp: (JSC::FTL::LowerDFGToLLVM::lower): * ftl/FTLOutput.cpp: (JSC::FTL::Output::Output): (JSC::FTL::Output::~Output): * ftl/FTLOutput.h: (JSC::FTL::Output::appendTo): * ftl/FTLState.cpp: (JSC::FTL::State::State): (JSC::FTL::State::~State): * ftl/WebKitLLVMLibraryAnchor.cpp: Removed. * jsc.cpp: (jscmain): * llvm: Added. * llvm/InitializeLLVM.cpp: Added.
