UnnamedAddressKind

public enum UnnamedAddressKind

Enumerates values representing whether or not this global value’s address is significant in this module or the program at large. A global value’s address is considered significant if it is referenced by any module in the final program.

This attribute is intended to be used only by the code generator and LTO to allow the linker to decide whether the global needs to be in the symbol table. Constant global values with unnamed addresses and identical initializers may be merged by LLVM. Note that a global value with an unnamed address may be merged with a global value with a significant address resulting in a global value with a significant address.

  • Indicates that the address of this global value is significant in this module.

    Declaration

    Swift

    case none

  • Indicates that the address of this global value is not significant to the current module but it may or may not be significant to another module; only the content of the value is known to be significant within the current module.

    Declaration

    Swift

    case local

  • Indicates that the address of this global value is not significant to the current module or any other module; only the content of the value is significant globally.

    Declaration

    Swift

    case global
