Function Documentation

◆ allowODRLikeMergeInC()

static bool allowODRLikeMergeInC ( NamedDecl * ND )

static

ODR-like semantics for C/ObjC allow us to merge tag types and a structural check in Sema guarantees the types can be merged (see C11 6.2.7/1 or C89 6.1.2.6/1).

Although most merging is done in Sema, we need to guarantee that some types are mergeable during deserialization, otherwise name lookup fails. This is the case for EnumConstantDecl.

◆ assert_cast() [1/2]

template<typename T >

static T assert_cast ( ... )

static

Definition at line 2880 of file ASTReaderDecl.cpp.

◆ assert_cast() [2/2]

template<typename T >

static T assert_cast ( T t )

static

"Cast" to type T, asserting if we don't have an implicit conversion.

We use this to put code in a template that will only be valid for certain instantiations.

Definition at line 2879 of file ASTReaderDecl.cpp.

◆ forAllLaterRedecls()

◆ getDeclForMerging()

static NamedDecl * getDeclForMerging	(	NamedDecl *	Found,
		bool	IsTypedefNameForLinkage
	)

static

Find the declaration that should be merged into, given the declaration found by name lookup.

If we're merging an anonymous declaration within a typedef, we need a matching typedef, and we merge with the type inside it.

Definition at line 3319 of file ASTReaderDecl.cpp.

◆ inheritDefaultTemplateArgument()

template<typename ParmDecl >

static bool inheritDefaultTemplateArgument	(	ASTContext &	Context,
		ParmDecl *	From,
		Decl *	ToD
	)

static

Inherit the default template argument from From to To.

Returns false if there is no default template for From.

◆ isConsumerInterestedIn()

static bool isConsumerInterestedIn	(	ASTContext &	Ctx,
		Decl *	D,
		bool	HasBody
	)

static

Determine whether the consumer will be interested in seeing this declaration (via HandleTopLevelDecl).

This routine should return true for anything that might affect code generation, e.g., inline function definitions, Objective-C declarations with metadata, etc.
