Expand description

These are bitcode-specific values, different from C++ enum

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

External = 0

Externally visible function

WeakAnyOld = 1

👎Deprecated

Keep one copy of named function when linking (weak) Old value with implicit comdat.

Appending = 2

Special purpose, only applies to global arrays

Internal = 3

Rename collisions when linking (static functions).

LinkOnceAnyOld = 4

👎Deprecated

Keep one copy of function when linking (inline) Old value with implicit comdat.

DllImport = 5

👎Deprecated

Externally visible function Obsolete DLLImportLinkage

DllExport = 6

👎Deprecated

Externally visible function Obsolete DLLExportLinkage

ExternWeak = 7

ExternalWeak linkage

Common = 8

Tentative definitions.

Private = 9

Like Internal, but omit from symbol table.

WeakOdrOld = 10

👎Deprecated

Same, but only replaced by something equivalent. Old value with implicit comdat.

LinkOnceOdrOld = 11

👎Deprecated

Same, but only replaced by something equivalent. Old value with implicit comdat.

AvailableExternally = 12

Available for inspection, not emission.

LinkerPrivate = 13

👎Deprecated

Like Internal, but omit from symbol table. Obsolete LinkerPrivateLinkage

LinkerPrivateWeak = 14

👎Deprecated

Like Internal, but omit from symbol table. Obsolete LinkerPrivateWeakLinkage

LinkOnceOdrAutoHide = 15

👎Deprecated

Externally visible function Obsolete LinkOnceODRAutoHideLinkage

WeakAny = 16

Keep one copy of named function when linking (weak)

WeakOdr = 17

Same, but only replaced by something equivalent.

LinkOnceAny = 18

Keep one copy of function when linking (inline)

LinkOnceOdr = 19

Same, but only replaced by something equivalent.
