Flags

public class Flags

Represents flags that describe information about the module for use by an external entity e.g. the dynamic linker.

Warning

Module flags are not a general runtime metadata infrastructure, and may be stripped by LLVM. As of the current release, LLVM hardcodes support for object-file emission of module flags related to Objective-C.

  • Enumerates the supported behaviors for resolving collisions when two module flags share the same key. These collisions can occur when the different flags are inserted under the same key, or when modules containing flags under the same key are merged.
