Detailed Description

Reads an AST files chain containing the contents of a translation unit.

The ASTReader class reads bitstreams (produced by the ASTWriter class) containing the serialized representation of a given abstract syntax tree and its supporting data structures. An instance of the ASTReader can be attached to an ASTContext object, which will provide access to the contents of the AST files.

The AST reader provides lazy de-serialization of declarations, as required when traversing the AST. Only those AST nodes that are actually required will be de-serialized.

Constructor & Destructor Documentation

ASTReader::ASTReader	(	Preprocessor &	PP,
		ASTContext &	Context,
		StringRef	isysroot = `""`,
		bool	DisableValidation = `false`,
		bool	DisableStatCache = `false`,
		bool	AllowASTWithCompilerErrors = `false`
	)

Load the AST file and validate its contents against the given Preprocessor.

Parameters:

PP	the preprocessor associated with the context in which this precompiled header will be loaded.
Context	the AST context that this precompiled header will be loaded into.
isysroot	If non-NULL, the system include path specified by the user. This is only used with relocatable PCH files. If non-NULL, a relocatable PCH file will use the default path "/".
DisableValidation	If true, the AST reader will suppress most of its regular consistency checking, allowing the use of precompiled headers that cannot be determined to be compatible.
DisableStatCache	If true, the AST reader will ignore the stat cache in the AST files. This performance pessimization can help when an AST file is being used in cases where the underlying files in the file system may have changed, but parsing should still continue.
AllowASTWithCompilerErrors	If true, the AST reader will accept an AST file the was created out of an AST with compiler errors, otherwise it will reject it.

Read the set of tentative definitions known to the external Sema source.

The external source should append its own tentative definitions to the given vector of tentative definitions. Note that this routine may be invoked multiple times; the external source should take care not to introduce the same declarations repeatedly.

void ASTReader::SetGloballyVisibleDecls	(	IdentifierInfo *	II,
		const SmallVectorImpl< uint32_t > &	DeclIDs,
		bool	Nonrecursive = `false`
	)

Set the globally-visible declarations associated with the given identifier.

If the AST reader is currently in a state where the given declaration IDs cannot safely be resolved, they are queued until it is safe to resolve them.

Parameters:

II	an IdentifierInfo that refers to one or more globally-visible declarations.
DeclIDs	the set of declaration IDs with the name `II` that are visible at global scope.
Nonrecursive	should be true to indicate that the caller knows that this call is non-recursive, and therefore the globally-visible declarations will not be placed onto the pending queue.
