Severity	Code	Description	Project	File	Line	Suppression State	Details
Error	LNK2005	"public: __cdecl llvm::PredicateInfo::~PredicateInfo(void)" (??1PredicateInfo@llvm@@QEAA@XZ) already defined in LLVMTableGenCommon.lib(CodeGenTarget.cpp.obj)	rpcs3	M:\console\git\rpcs3_diga\rpcs3\LLVMTransformUtils.lib(PredicateInfo.cpp.obj)	1
