Functions
static void	makeScopes (Sema &sema, DeclContext *ctxt, std::vector< Scope * > &result)
	Builds a list of scopes that point into the given context.

createDecl()

template<typename T , typename... Args>

T * createDecl	(	ASTImporter &	importer,
		Decl *	from_d,
		Args &&...	args
	)

Constructor function for Clang declarations.

Ensures that the created declaration is registered with the ASTImporter.

emulateLookupInCtxt()

static std::unique_ptr< LookupResult > emulateLookupInCtxt ( Sema &  sema, llvm::StringRef  name, DeclContext *  ctxt  )

static

Uses the Sema to look up the given name in the given DeclContext.

getEqualLocalDeclContext()

static llvm::Expected< DeclContext * > getEqualLocalDeclContext ( Sema &  sema, DeclContext *  foreign_ctxt  )

static

Given a foreign decl context, this function finds the equivalent local decl context in the ASTContext of the given Sema.

Potentially deserializes decls from the 'std' module if necessary.

makeScopes()

static void makeScopes ( Sema &  sema, DeclContext *  ctxt, std::vector< Scope * > &  result  )

static

Builds a list of scopes that point into the given context.

Parameters

sema	The sema that will be using the scopes.
ctxt	The context that the scope should look into.
result	A list of scopes. The scopes need to be freed by the caller (except the TUScope which is owned by the sema).
