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.

Member Enumeration Documentation

enum clang::ASTReader::ASTReadResult

The result of reading the control block of an AST file, which can fail for various reasons.

Enumerator:

Success	The control block was read successfully. Aside from failures, the AST file is safe to read into the current context.
Failure	The AST file itself appears corrupted.
Missing	The AST file was missing.
OutOfDate	The AST file is out-of-date relative to its input files, and needs to be regenerated.
VersionMismatch	The AST file was written by a different version of Clang.
ConfigurationMismatch	The AST file was writtten with a different language/target configuration.
HadErrors	The AST file has errors.

Definition at line 310 of file ASTReader.h.

enum clang::ASTReader::LoadFailureCapabilities

Flags that indicate what kind of AST loading failures the client of the AST reader can directly handle.

When a client states that it can handle a particular kind of failure, the AST reader will not emit errors when producing that kind of failure.

Enumerator:

ARR_None	The client can't handle any AST loading failures.
ARR_Missing	The client can handle an AST file that cannot load because it is missing.
ARR_OutOfDate	The client can handle an AST file that cannot load because it is out-of-date relative to its input files.
ARR_VersionMismatch	The client can handle an AST file that cannot load because it was built with a different version of Clang.
ARR_ConfigurationMismatch	The client can handle an AST file that cannot load because it's compiled configuration doesn't match that of the context it was loaded into.

Definition at line 1351 of file ASTReader.h.

Constructor & Destructor Documentation

ASTReader::ASTReader	(	Preprocessor &	PP,
		ASTContext &	Context,
		StringRef	isysroot = `""`,
		bool	DisableValidation = `false`,
		bool	AllowASTWithCompilerErrors = `false`,
		bool	AllowConfigurationMismatch = `false`,
		bool	ValidateSystemInputs = `false`,
		bool	UseGlobalIndex = `true`
	)

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.
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.
AllowConfigurationMismatch	If true, the AST reader will not check for configuration differences between the AST file and the invocation.
ValidateSystemInputs	If true, the AST reader will validate system input files in addition to user input files. This is only meaningful if `DisableValidation` is false.
UseGlobalIndex	If true, the AST reader will try to load and use the global module index.
