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 2721 of file ASTReaderDecl.cpp.

◆ assert_cast() [2/2]

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 2720 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 3150 of file ASTReaderDecl.cpp.

References clang::Decl::isFromASTFile().

◆ 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.

Definition at line 3479 of file ASTReaderDecl.cpp.

◆ inheritDefaultTemplateArguments()

static void inheritDefaultTemplateArguments ( ASTContext Context,
TemplateDecl From,
TemplateDecl To 
)
static

◆ 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.
