addExplicitInstantiationDecl()

void addExplicitInstantiationDecl ( ASTContext & Context, DeclContext * CurContext, NamedDecl * Spec, SourceLocation ExternLoc, SourceLocation TemplateLoc, NestedNameSpecifierLoc QualifierLoc, const ASTTemplateArgumentListInfo * ArgsAsWritten, SourceLocation NameLoc, TypeSourceInfo * TypeAsWritten, TemplateSpecializationKind TSK )

static

Create an ExplicitInstantiationDecl to record source-location info for an explicit template instantiation statement, and add it to CurContext.

For class templates / nested classes, the caller should build a TypeSourceInfo that encodes the tag keyword, qualifier, name, and template arguments, and pass empty QualifierLoc / null ArgsAsWritten.

For function / variable templates, the caller should pass TypeAsWritten for the declared type, and separate QualifierLoc / ArgsAsWritten.

Check whether a specialization is well-formed in the current context.

Parameters

S	the semantic analysis object for which this check is being performed.
Specialized	the entity being specialized or instantiated, which may be a kind of template (class template, function template, etc.) or a member of a class template (member function, static data member, member class).
PrevDecl	the previous declaration of this entity, if any.
Loc	the location of the explicit specialization or instantiation of this entity.
IsPartialSpecialization	whether this is a partial specialization of a class template.

Returns
