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]

static T assert_cast (   ... )

Definition at line 2909 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.

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.

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.
