clang: clang::LayoutOverrideSource Class Reference
An external AST source that overrides the layout of a specified set of record types. More...
LayoutOverrideSource (StringRef Filename) Create a new AST source that overrides the layout of some set of record types.
bool layoutRecordType (const RecordDecl *Record, uint64_t &Size, uint64_t &Alignment, llvm::DenseMap< const FieldDecl *, uint64_t > &FieldOffsets, llvm::DenseMap< const CXXRecordDecl *, CharUnits > &BaseOffsets, llvm::DenseMap< const CXXRecordDecl *, CharUnits > &VirtualBaseOffsets) override If this particular record type has an overridden layout, return that layout.
void dump () Dump the overridden layouts.
ExternalASTSource ()=default virtual ~ExternalASTSource () uint32_t getGeneration () const Get the current generation of this AST source.
virtual Decl * GetExternalDecl (GlobalDeclID ID) Resolve a declaration ID into a declaration, potentially building a new declaration.
virtual Selector GetExternalSelector (uint32_t ID) Resolve a selector ID into a selector.
virtual uint32_t GetNumExternalSelectors () Returns the number of selectors known to the external AST source.
virtual Stmt * GetExternalDeclStmt (uint64_t Offset) Resolve the offset of a statement in the decl stream into a statement.
virtual CXXCtorInitializer ** GetExternalCXXCtorInitializers (uint64_t Offset) Resolve the offset of a set of C++ constructor initializers in the decl stream into an array of initializers.
virtual CXXBaseSpecifier * GetExternalCXXBaseSpecifiers (uint64_t Offset) Resolve the offset of a set of C++ base specifiers in the decl stream into an array of specifiers.
virtual void updateOutOfDateIdentifier (const IdentifierInfo &II) Update an out-of-date identifier.
virtual bool FindExternalVisibleDeclsByName (const DeclContext *DC, DeclarationName Name, const DeclContext *OriginalDC) Find all declarations with the given name in the given context, and add them to the context by calling SetExternalVisibleDeclsForName or SetNoExternalVisibleDeclsForName.
virtual bool LoadExternalSpecializations (const Decl *D, bool OnlyPartial) Load all the external specializations for the Decl.
virtual bool LoadExternalSpecializations (const Decl *D, ArrayRef< TemplateArgument > TemplateArgs) Load all the specializations for the Decl.
virtual void completeVisibleDeclsMap (const DeclContext *DC) Ensures that the table of all visible declarations inside this context is up to date.
virtual Module * getModule (unsigned ID) Retrieve the module that corresponds to the given module ID.
virtual std::optional< ASTSourceDescriptor > getSourceDescriptor (unsigned ID) Return a descriptor for the corresponding module, if one exists.
virtual ExtKind hasExternalDefinitions (const Decl *D) virtual void FindExternalLexicalDecls (const DeclContext *DC, llvm::function_ref< bool(Decl::Kind)> IsKindWeWant, SmallVectorImpl< Decl * > &Result) Finds all declarations lexically contained within the given DeclContext, after applying an optional filter predicate.
void FindExternalLexicalDecls (const DeclContext *DC, SmallVectorImpl< Decl * > &Result) Finds all declarations lexically contained within the given DeclContext.
virtual void FindFileRegionDecls (FileID File, unsigned Offset, unsigned Length, SmallVectorImpl< Decl * > &Decls) Get the decls that are contained in a file in the Offset/Length range.
virtual void CompleteRedeclChain (const Decl *D) Gives the external AST source an opportunity to complete the redeclaration chain for a declaration.
virtual void CompleteType (TagDecl *Tag) Gives the external AST source an opportunity to complete an incomplete type.
virtual void CompleteType (ObjCInterfaceDecl *Class) Gives the external AST source an opportunity to complete an incomplete Objective-C class.
virtual void ReadComments () Loads comment ranges.
virtual void StartedDeserializing () Notify ExternalASTSource that we started deserialization of a decl or type so until FinishedDeserializing is called there may be decls that are initializing.
virtual void FinishedDeserializing () Notify ExternalASTSource that we finished the deserialization of a decl or type.
virtual void StartTranslationUnit (ASTConsumer *Consumer) Function that will be invoked when we begin parsing a new translation unit involving this external AST source.
virtual void PrintStats () Print any statistics that have been gathered regarding the external AST source.
virtual bool layoutRecordType (const RecordDecl *Record, uint64_t &Size, uint64_t &Alignment, llvm::DenseMap< const FieldDecl *, uint64_t > &FieldOffsets, llvm::DenseMap< const CXXRecordDecl *, CharUnits > &BaseOffsets, llvm::DenseMap< const CXXRecordDecl *, CharUnits > &VirtualBaseOffsets) Perform layout on the given record.
MemoryBufferSizes getMemoryBufferSizes () const Return the amount of memory used by memory buffers, breaking down by heap-backed versus mmap'ed memory.
virtual void getMemoryBufferSizes (MemoryBufferSizes &sizes) const virtual bool isA (const void *ClassID) const LLVM-style RTTI.
An external AST source that overrides the layout of a specified set of record types.
This class is used only for testing the ability of external AST sources to override the layout of record types. Its input is the output format of the command-line argument -fdump-record-layouts.
