Typedef Documentation

typedef uint32_t clang::serialization::CXXBaseSpecifiersID

An ID number that refers to a set of CXXBaseSpecifiers in an AST file.

Definition at line 138 of file ASTBitCodes.h.

typedef uint32_t clang::serialization::DeclID

An ID number that refers to a declaration in an AST file.

The ID numbers of declarations are consecutive (in order of discovery), with values below NUM_PREDEF_DECL_IDS being reserved. At the start of a chain of precompiled headers, declaration ID 1 is used for the translation unit declaration.

typedef uint32_t clang::serialization::IdentID

An ID number that refers to an identifier in an AST file.

Definition at line 125 of file ASTBitCodes.h.

typedef uint32_t clang::serialization::IdentifierID

An ID number that refers to an identifier in an AST file.

The ID numbers of identifiers are consecutive (in order of discovery) and start at 1. 0 is reserved for NULL.

typedef uint32_t clang::serialization::SubmoduleID

An ID number that refers to a submodule in a module file.

Definition at line 145 of file ASTBitCodes.h.

typedef uint32_t clang::serialization::TypeID

An ID number that refers to a type in an AST file.

The ID of a type is partitioned into two parts: the lower three bits are used to store the const/volatile/restrict qualifiers (as with QualType) and the upper bits provide a type index. The type index values are partitioned into two sets. The values below NUM_PREDEF_TYPE_IDs are predefined type IDs (based on the PREDEF_TYPE_*_ID constants), with 0 as a placeholder for "no type". Values from NUM_PREDEF_TYPE_IDs are other types that have serialized representations.

Definition at line 82 of file ASTBitCodes.h.

Enumeration Type Documentation

enum clang::serialization::ASTRecordTypes

Record types that occur within the AST block itself.

Enumerator:

TYPE_OFFSET	Record code for the offsets of each type. The TYPE_OFFSET constant describes the record that occurs within the AST block. The record itself is an array of offsets that point into the declarations and types block (identified by DECLTYPES_BLOCK_ID). The index into the array is based on the ID of a type. For a given type ID `T`, the lower three bits of `T` are its qualifiers (const, volatile, restrict), as in the QualType class. The upper bits, after being shifted and subtracting NUM_PREDEF_TYPE_IDS, are used to index into the TYPE_OFFSET block to determine the offset of that type's corresponding record within the DECLTYPES_BLOCK_ID block.
DECL_OFFSET	Record code for the offsets of each decl. The DECL_OFFSET constant describes the record that occurs within the block identified by DECL_OFFSETS_BLOCK_ID within the AST block. The record itself is an array of offsets that point into the declarations and types block (identified by DECLTYPES_BLOCK_ID). The declaration ID is an index into this record, after subtracting one to account for the use of declaration ID 0 for a NULL declaration pointer. Index 0 is reserved for the translation unit declaration.
LANGUAGE_OPTIONS	Record code for the language options table. The record with this code contains the contents of the LangOptions structure. We serialize the entire contents of the structure, and let the reader decide which options are actually important to check.
METADATA	AST file metadata, including the AST file version number and the target triple used to build the AST file.
IDENTIFIER_OFFSET	Record code for the table of offsets of each identifier ID. The offset table contains offsets into the blob stored in the IDENTIFIER_TABLE record. Each offset points to the NULL-terminated string that corresponds to that identifier.
IDENTIFIER_TABLE	Record code for the identifier table. The identifier table is a simple blob that contains NULL-terminated strings for all of the identifiers referenced by the AST file. The IDENTIFIER_OFFSET table contains the mapping from identifier IDs to the characters in this blob. Note that the starting offsets of all of the identifiers are odd, so that, when the identifier offset table is loaded in, we can use the low bit to distinguish between offsets (for unresolved identifier IDs) and IdentifierInfo pointers (for already-resolved identifier IDs).
EXTERNAL_DEFINITIONS	Record code for the array of external definitions. The AST file contains a list of all of the unnamed external definitions present within the parsed headers, stored as an array of declaration IDs. These external definitions will be reported to the AST consumer after the AST file has been read, since their presence can affect the semantics of the program (e.g., for code generation).
SPECIAL_TYPES	Record code for the set of non-builtin, special types. This record contains the type IDs for the various type nodes that are constructed during semantic analysis (e.g., __builtin_va_list). The SPECIAL_TYPE_* constants provide offsets into this record.
STATISTICS	Record code for the extra statistics we gather while generating an AST file.
TENTATIVE_DEFINITIONS	Record code for the array of tentative definitions.
LOCALLY_SCOPED_EXTERNAL_DECLS	Record code for the array of locally-scoped external declarations.
SELECTOR_OFFSETS	Record code for the table of offsets into the Objective-C method pool.
METHOD_POOL	Record code for the Objective-C method pool,.
PP_COUNTER_VALUE	The value of the next __COUNTER__ to dispense. [PP_COUNTER_VALUE, Val].
SOURCE_LOCATION_OFFSETS	Record code for the table of offsets into the block of source-location information.
SOURCE_LOCATION_PRELOADS	Record code for the set of source location entries that need to be preloaded by the AST reader. This set contains the source location entry for the predefines buffer and for any file entries that need to be preloaded.
STAT_CACHE	Record code for the stat() cache.
EXT_VECTOR_DECLS	Record code for the set of ext_vector type names.
ORIGINAL_FILE_NAME	Record code for the original file that was used to generate the AST file.
ORIGINAL_FILE_ID	Record code for the file ID of the original file used to generate the AST file.
VERSION_CONTROL_BRANCH_REVISION	Record code for the version control branch and revision information of the compiler used to build this AST file.
UNUSED_FILESCOPED_DECLS	Record code for the array of unused file scoped decls.
PPD_ENTITIES_OFFSETS	Record code for the table of offsets to entries in the preprocessing record.
VTABLE_USES	Record code for the array of VTable uses.
DYNAMIC_CLASSES	Record code for the array of dynamic classes.
IMPORTS	Record code for the list of other AST files imported by this AST file.
REFERENCED_SELECTOR_POOL	Record code for referenced selector pool.
TU_UPDATE_LEXICAL	Record code for an update to the TU's lexically contained declarations.
LOCAL_REDECLARATIONS_MAP	Record code for the array describing the locations (in the LOCAL_REDECLARATIONS record) of the redeclaration chains, indexed by the first known ID.
SEMA_DECL_REFS	Record code for declarations that Sema keeps references of.
WEAK_UNDECLARED_IDENTIFIERS	Record code for weak undeclared identifiers.
PENDING_IMPLICIT_INSTANTIATIONS	Record code for pending implicit instantiations.
DECL_REPLACEMENTS	Record code for a decl replacement block. If a declaration is modified after having been deserialized, and then written to a dependent AST file, its ID and offset must be added to the replacement block.
UPDATE_VISIBLE	Record code for an update to a decl context's lookup table. In practice, this should only be used for the TU and namespaces.
DECL_UPDATE_OFFSETS	Record for offsets of DECL_UPDATES records for declarations that were modified after being deserialized and need updates.
DECL_UPDATES	Record of updates for a declaration that was modified after being deserialized.
CXX_BASE_SPECIFIER_OFFSETS	Record code for the table of offsets to CXXBaseSpecifier sets.
DIAG_PRAGMA_MAPPINGS	Record code for #pragma diagnostic mappings.
CUDA_SPECIAL_DECL_REFS	Record code for special CUDA declarations.
HEADER_SEARCH_TABLE	Record code for header search information.
ORIGINAL_PCH_DIR	The directory that the PCH was originally created in.
FP_PRAGMA_OPTIONS	Record code for floating point #pragma options.
OPENCL_EXTENSIONS	Record code for enabled OpenCL extensions.
DELEGATING_CTORS	The list of delegating constructor declarations.
FILE_SOURCE_LOCATION_OFFSETS	Record code for the table of offsets into the block of file source-location information.
KNOWN_NAMESPACES	Record code for the set of known namespaces, which are used for typo correction.
MODULE_OFFSET_MAP	Record code for the remapping information used to relate loaded modules to the various offsets and IDs(e.g., source location offests, declaration and type IDs) that are used in that module to refer to other modules.
SOURCE_MANAGER_LINE_TABLE	Record code for the source manager line table information, which stores information about #line directives.
OBJC_CATEGORIES_MAP	Record code for map of Objective-C class definition IDs to the ObjC categories in a module that are attached to that class.
FILE_SORTED_DECLS	Record code for a file sorted array of DeclIDs in a module.
IMPORTED_MODULES	Record code for an array of all of the (sub)modules that were imported by the AST file.
MERGED_DECLARATIONS	Record code for the set of merged declarations in an AST file.
LOCAL_REDECLARATIONS	Record code for the array of redeclaration chains. This array can only be interpreted properly using the local redeclarations map.
OBJC_CATEGORIES	Record code for the array of Objective-C categories (including extensions). This array can only be interpreted properly using the Objective-C categories map.

SM_SLOC_FILE_ENTRY	Describes a source location entry (SLocEntry) for a file.
SM_SLOC_BUFFER_ENTRY	Describes a source location entry (SLocEntry) for a buffer.
SM_SLOC_BUFFER_BLOB	Describes a blob that contains the data for a buffer entry. This kind of record always directly follows a SM_SLOC_BUFFER_ENTRY record or a SM_SLOC_FILE_ENTRY with an overridden buffer.
SM_SLOC_EXPANSION_ENTRY	Describes a source location entry (SLocEntry) for a macro expansion.

const unsigned clang::serialization::VERSION_MAJOR = 4

AST file major version number supported by this version of Clang.

Whenever the AST file format changes in a way that makes it incompatible with previous versions (such that a reader designed for the previous version could not support reading the new version), this number should be increased.

Version 4 of AST files also requires that the version control branch and revision match exactly, since there is no backward compatibility of AST files at this time.

Definition at line 38 of file ASTBitCodes.h.

const unsigned clang::serialization::VERSION_MINOR = 0

AST file minor version number supported by this version of Clang.

Whenever the AST format changes in a way that is still compatible with previous versions (such that a reader designed for the previous version could still support reading the new version by ignoring new kinds of subblocks), this number should be increased.
