Member Function Documentation

getArgInfo()

Info CXXNameMangler::TemplateArgManglingInfo::getArgInfo ( unsigned  ParamIdx, const TemplateArgument &  Arg  )

inline

Determine information about how this template argument should be mangled.

This should be called exactly once for each parameter / argument pair, in order.

getTrailingRequiresClauseToMangle()

const Expr * CXXNameMangler::TemplateArgManglingInfo::getTrailingRequiresClauseToMangle ( )

inline

Determine if we should mangle a requires-clause after the template argument list.

If so, returns the expression to mangle.

Definition at line 6161 of file ItaniumMangle.cpp.

References clang::TemplateParameterList::getRequiresClause(), clang::TemplateDecl::getTemplateParameters(), isOverloadable(), and ResolvedTemplate.

isOverloadable()

bool CXXNameMangler::TemplateArgManglingInfo::isOverloadable ( )

inline

Determine whether the resolved template might be overloaded on its template parameter list.

If so, the mangling needs to include enough information to reconstruct the template parameter list.

Definition at line 6026 of file ItaniumMangle.cpp.

needToMangleTemplateParam()

bool CXXNameMangler::TemplateArgManglingInfo::needToMangleTemplateParam ( const NamedDecl *  Param, const TemplateArgument &  Arg  )

inline

Determine whether we need to prefix this <template-arg> mangling with a <template-param-decl>.

This happens if the natural template parameter for the argument mangling is not the same as the actual template parameter.
