◆ wasDeclEmitted()

bool ASTWriter::wasDeclEmitted ( const Decl * D ) const

Whether or not the declaration got emitted.

If not, it wouldn't be emitted.

This may only be called after we've done the job to write the declarations (marked by DoneWritingDeclsAndTypes).

A declaration may only be omitted in reduced BMI.

Definition at line 6889 of file ASTWriter.cpp.

◆ WriteAST()

ASTFileSignature ASTWriter::WriteAST	(	llvm::PointerUnion< Sema , Preprocessor >	Subject,
		StringRef	OutputFile,
		Module *	WritingModule,
		StringRef	isysroot,
		bool	ShouldCacheASTInMemory = `false`
	)

Write a precompiled header or a module with the AST produced by the Sema object, or a dependency scanner module with the preprocessor state produced by the Preprocessor object.

Parameters

Subject	The `Sema` object that processed the AST to be written, or in the case of a dependency scanner module the `Preprocessor` that holds the state.
WritingModule	The module that we are writing. If null, we are writing a precompiled header.
isysroot	if non-empty, write a relocatable file whose headers are relative to the given system root. If we're writing a module, its build directory will be used in preference to this if both are available.

Returns: the module signature, which eventually will be a hash of the module but currently is merely a random 32-bit number.
