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.

Definition at line 2592 of file ASTReaderDecl.cpp.

◆ assert_cast() [1/2]

template<typename T >
static T assert_cast ( 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 2500 of file ASTReaderDecl.cpp.

◆ assert_cast() [2/2]

template<typename T >
static T assert_cast (   ...)
static

Definition at line 2501 of file ASTReaderDecl.cpp.

◆ forAllLaterRedecls()

template<typename DeclT , typename Fn >
static void forAllLaterRedecls ( DeclT *  D,
Fn  F 
)
static

◆ 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 3206 of file ASTReaderDecl.cpp.

◆ getNamespace()

static NamespaceDecl* getNamespace ( const NestedNameSpecifier X)
static

◆ hasSameOverloadableAttrs()

static bool hasSameOverloadableAttrs ( const FunctionDecl A,
const FunctionDecl B 
)
static

Determine whether the attributes we can overload on are identical for A and B.

Will ignore any overloadable attrs represented in the type of A and B.

◆ 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.

◆ isSameTemplateParameter()

static bool isSameTemplateParameter ( const NamedDecl X,
const NamedDecl Y 
)
static

Determine whether two template parameters are similar enough that they may be used in declarations of the same template.

◆ isSameTemplateParameterList()

static bool isSameTemplateParameterList ( const TemplateParameterList X,

static

Determine whether two template parameter lists are similar enough that they may be used in declarations of the same template.
