Member Enumeration Documentation

enum llvm::GlobalValue::LinkageTypes

An enumeration for the kinds of linkage for global values.

Enumerator:

ExternalLinkage	Externally visible function.
AvailableExternallyLinkage	Available for inspection, not emission.
LinkOnceAnyLinkage	Keep one copy of function when linking (inline)
LinkOnceODRLinkage	Same, but only replaced by something equivalent.
LinkOnceODRAutoHideLinkage	Like LinkOnceODRLinkage but addr not taken.
WeakAnyLinkage	Keep one copy of named function when linking (weak)
WeakODRLinkage	Same, but only replaced by something equivalent.
AppendingLinkage	Special purpose, only applies to global arrays.
InternalLinkage	Rename collisions when linking (static functions).
PrivateLinkage	Like Internal, but omit from symbol table.
LinkerPrivateLinkage	Like Private, but linker removes.
LinkerPrivateWeakLinkage	Like LinkerPrivate, but weak.
DLLImportLinkage	Function to be imported from DLL.
DLLExportLinkage	Function to be accessible from DLL.
ExternalWeakLinkage	ExternalWeak linkage description.
CommonLinkage	Tentative definitions.

bool llvm::GlobalValue::use_empty_except_constants ( )

Determine if the usage of this global value is empty except for transitively dead constants.

If the usage is empty (except transitively dead constants), then this global value can be safely deleted since the destructor will delete the dead constants as well.
