SubmoduleID

using clang::serialization::SubmoduleID = typedef uint32_t

Definition at line 185 of file ASTBitCodes.h.

TypeID

using clang::serialization::TypeID = typedef uint64_t

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

The ID of a type is partitioned into three parts:

• the lower three bits are used to store the const/volatile/restrict qualifiers (as with QualType).
• the next 29 bits provide a type index in the corresponding module file.
• the upper 32 bits provide a module file 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". The module file index for predefined types are always 0 since they don't belong to any modules. Values from NUM_PREDEF_TYPE_IDs are other types that have serialized representations.

Definition at line 88 of file ASTBitCodes.h.

Enumeration Type Documentation

ASTRecordTypes

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.
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.
METADATA_OLD_FORMAT	This is so that older clang versions, before the introduction of the control block, can read and reject the newer PCH format. DON'T CHANGE THIS NUMBER.
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).
EAGERLY_DESERIALIZED_DECLS	Record code for the array of eagerly deserialized decls. The AST file contains a list of all of the declarations that should be eagerly deserialized present within the parsed headers, stored as an array of declaration IDs. These declarations 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.
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.
EXT_VECTOR_DECLS	Record code for the set of ext_vector type names.
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.
REFERENCED_SELECTOR_POOL	Record code for referenced selector pool.
TU_UPDATE_LEXICAL	Record code for an update to the TU's lexically contained declarations.
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.
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.
CUDA_SPECIAL_DECL_REFS	Record code for special CUDA declarations.
HEADER_SEARCH_TABLE	Record code for header search information.
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.
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.
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.
MACRO_OFFSET	Record code for the table of offsets of each macro ID. The offset table contains offsets into the blob stored in the preprocessor block. Each offset points to the corresponding macro definition.
INTERESTING_IDENTIFIERS	A list of "interesting" identifiers. Only used in C++ (where we don't normally do lookups into the serialized identifier table). These are eagerly deserialized.
UNDEFINED_BUT_USED	Record code for undefined but used functions and variables that need a definition in this TU.
LATE_PARSED_TEMPLATE	Record code for late parsed template functions.

Retrieve the "definitive" declaration that provides all of the visible entries for the given declaration context, if there is one.

The "definitive" declaration is the only place where we need to look to find information about the declarations within the given declaration context. For example, C++ and Objective-C classes, C structs/unions, and Objective-C protocols, categories, and extensions are all defined in a single place in the source code, so they have definitive declarations associated with them. C++ namespaces, on the other hand, can have multiple definitions.

VERSION_MAJOR

const unsigned clang::serialization::VERSION_MAJOR = 31

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.

VERSION_MINOR

const unsigned clang::serialization::VERSION_MINOR = 1

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.
