WeakLinkage  Keep one copy of named function when linking (weak). AppendingLinkage  Special purpose, only applies to global arrays. InternalLinkage  Rename collisions when linking (static functions). DLLImportLinkage  Function to be imported from DLL. DLLExportLinkage  Function to be accessible from DLL. ExternalWeakLinkage  ExternalWeak linkage description. GhostLinkage  Stand-in functions for streaming fns from BC files. CommonLinkage  Tentative definitions. Definition at line 32 of file GlobalValue.h.

enum llvm::GlobalValue::VisibilityTypes

An enumeration for the kinds of visibility of global values. Enumeration values: DefaultVisibility  The GV is visible. HiddenVisibility  The GV is hidden. ProtectedVisibility  The GV is protected. Definition at line 46 of file GlobalValue.h.
