Member Typedef Documentation

◆ ExportSetTy

using llvm::FunctionImporter::ExportSetTy = std::unordered_set<GlobalValue::GUID>

The set contains an entry for every global value the module exports.

Definition at line 102 of file FunctionImport.h.

◆ FunctionsToImportTy

using llvm::FunctionImporter::FunctionsToImportTy = std::unordered_set<GlobalValue::GUID>

Set of functions to import from a source module.

Each entry is a set containing all the GUIDs of all functions to import for a source module.

Definition at line 38 of file FunctionImport.h.

◆ ImportMapTy

using llvm::FunctionImporter::ImportMapTy = StringMap<FunctionsToImportTy>

The map contains an entry for every module to import from, the key being the module identifier to pass to the ModuleLoader.

The value is the set of functions to import.

Definition at line 99 of file FunctionImport.h.

◆ ImportThresholdsTy

using llvm::FunctionImporter::ImportThresholdsTy = DenseMap<GlobalValue::GUID, std::tuple<unsigned, const GlobalValueSummary *, std::unique_ptr<ImportFailureInfo> >>

Map of callee GUID considered for import into a given module to a pair consisting of the largest threshold applied when deciding whether to import it and, if we decided to import, a pointer to the summary instance imported.

If we decided not to import, the summary will be nullptr.

Definition at line 94 of file FunctionImport.h.

◆ ModuleLoaderTy

using llvm::FunctionImporter::ModuleLoaderTy = std::function<Expected<std::unique_ptr<Module> >(StringRef Identifier)>

A function of this type is used to load modules referenced by the index.

Definition at line 106 of file FunctionImport.h.

◆ ImportFailureReason

enum llvm::FunctionImporter::ImportFailureReason
