Linkage specification for functions and globals

public enum Linkage

Fields

Append = 7

Special purpose, applies only to global arrays

AvailableExternally = 1

Available Externally

Globals with “available_externally” linkage are never emitted into the object file corresponding to the LLVM module. From the linker’s perspective, an available_externally global is equivalent to an external declaration. They exist to allow in-lining and other optimizations to take place given knowledge of the definition of the global, which is known to be somewhere outside the module. Globals with available_externally linkage are allowed to be discarded at will, and allow in-lining and other optimizations. This linkage type is only allowed on definitions, not declarations.

Common = 14

Tentative definitions

DllExport = 11

Global to be Exported from a DLL

DllImport = 10

Global to be imported from a DLL

External = 0

Externally visible Global

ExternalWeak = 12

External weak linkage

The semantics of this linkage follow the ELF object file model: the symbol is weak until linked, if not linked, the symbol becomes null instead of being an undefined reference.

Internal = 8

Rename collision when linking (i.e static function)

LinkOnceAny = 2

Keep a single copy when linking

LinkOnceODR = 3

Like LinkOnceAny but can only be replaced by equivalent (One Definition Rule)

LinkerPrivate = 15

Like Private but the linker remove this symbol

LinkerPrivateWeak = 16

Weak form of LinkerPrivate

Private = 9

Link as Internal but omit from the generated symbol table

Weak = 5

Keep one copy when linking (weak)

WeakODR = 6

Like Weak but only replaced by something equivalent (e.g. One Definition Rule)
