Classes
class	llvm::lto::InputFile
	An input file. More...
class	llvm::lto::InputFile::Symbol
	The purpose of this class is to only expose the symbol information that an LTO client should need in order to do symbol resolution. More...
class	llvm::lto::NativeObjectStream
	This class wraps an output stream for a native object. More...
class	llvm::lto::LTO
	This class implements a resolution-based interface to LLVM's LTO functionality. More...
struct	llvm::lto::LTO::RegularLTOState::CommonResolution
struct	llvm::lto::LTO::RegularLTOState::AddedModule
struct	llvm::lto::SymbolResolution
	The resolution for a symbol. More...

Namespaces
	llvm
	This class represents lattice values for constants.
	llvm::lto

Typedefs
typedef std::function< std::unique_ptr< NativeObjectStream >unsigned Task)>	llvm::lto::AddStreamFn
	This type defines the callback to add a native object that is generated on the fly. More...
typedef std::function< AddStreamFn(unsigned Task, StringRef Key)>	llvm::lto::NativeObjectCache
	This is the type of a native object cache. More...
typedef std::function< std::unique_ptr< ThinBackendProc > Config &C, ModuleSummaryIndex &CombinedIndex, StringMap< GVSummaryMapTy > &ModuleToDefinedGVSummaries, AddStreamFn AddStream, NativeObjectCache Cache)>	llvm::lto::ThinBackend
	A ThinBackend defines what happens after the thin-link phase during ThinLTO. More...
using	llvm::lto::IndexWriteCallback = std::function< void(const std::string &)>
	This ThinBackend writes individual module indexes to files, instead of running the individual backend jobs. More...

Functions
void	llvm::thinLTOResolvePrevailingInIndex (ModuleSummaryIndex &Index, function_ref< bool(GlobalValue::GUID, const GlobalValueSummary *)> isPrevailing, function_ref< void(StringRef, GlobalValue::GUID, GlobalValue::LinkageTypes)> recordNewLinkage)
	Resolve linkage for prevailing symbols in the Index. More...
void	llvm::thinLTOInternalizeAndPromoteInIndex (ModuleSummaryIndex &Index, function_ref< bool(StringRef, GlobalValue::GUID)> isExported)
	Update the linkages in the given Index to mark exported values as external and non-exported values as internal. More...
void	llvm::computeLTOCacheKey (SmallString< 40 > &Key, const lto::Config &Conf, const ModuleSummaryIndex &Index, StringRef ModuleID, const FunctionImporter::ImportMapTy &ImportList, const FunctionImporter::ExportSetTy &ExportList, const std::map< GlobalValue::GUID, GlobalValue::LinkageTypes > &ResolvedODR, const GVSummaryMapTy &DefinedGlobals, const std::set< GlobalValue::GUID > &CfiFunctionDefs={}, const std::set< GlobalValue::GUID > &CfiFunctionDecls={})
	Computes a unique hash for the Module considering the current list of export/import and other global analysis results. More...
std::string	llvm::lto::getThinLTOOutputFile (const std::string &Path, const std::string &OldPrefix, const std::string &NewPrefix)
	Given the original Path to an output file, replace any path prefix matching OldPrefix with NewPrefix. More...
Expected< std::unique_ptr< ToolOutputFile > >	llvm::lto::setupOptimizationRemarks (LLVMContext &Context, StringRef LTORemarksFilename, bool LTOPassRemarksWithHotness, int Count=-1)
	Setup optimization remarks. More...
ThinBackend	llvm::lto::createInProcessThinBackend (unsigned ParallelismLevel)
	This ThinBackend runs the individual backend jobs in-process. More...
ThinBackend	llvm::lto::createWriteIndexesThinBackend (std::string OldPrefix, std::string NewPrefix, bool ShouldEmitImportsFiles, raw_fd_ostream *LinkedObjectsFile, IndexWriteCallback OnWrite)
