Include dependency graph for LTO.h:
This graph shows which files directly or indirectly include this file:

Go to the source code of this file.


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...


 Compute iterated dominance frontiers using a linear time algorithm.


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...


void llvm::thinLTOResolveWeakForLinkerInIndex (ModuleSummaryIndex &Index, function_ref< bool(GlobalValue::GUID, const GlobalValueSummary *)> isPrevailing, function_ref< void(StringRef, GlobalValue::GUID, GlobalValue::LinkageTypes)> recordNewLinkage)
 Resolve Weak and LinkOnce values 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...
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)
