Global
public struct Global: IRGlobal
A Global represents a region of memory allocated at compile time instead
of at runtime. A global variable must either have an initializer, or make
reference to an external definition that has an initializer.
-
Returns whether this global variable has no initializer because it makes reference to an initialized value in another translation unit.
Declaration
Swift
public var isExternallyInitialized: Bool -
Retrieves the initializer for this global variable, if it exists.
Declaration
Swift
public var initializer: IRValue? -
Returns whether this global variable is a constant, whether or not the final definition of the global is not.
Declaration
Swift
public var isGlobalConstant: Bool -
Returns whether this global variable is thread-local. That is, returns if this variable is not shared by multiple threads.
Declaration
Swift
public var isThreadLocal: Bool -
Accesses the model of reference for this global variable if it is thread-local.
Declaration
Swift
public var threadLocalMode: ThreadLocalModel -
Retrieves the previous global in the module, if there is one.
Declaration
Swift
public func previous() -> Global? -
Retrieves the next global in the module, if there is one.
Declaration
Swift
public func next() -> Global? -
Deletes the global variable from its containing module. - note: This does not remove references to this global from the module. Ensure you have removed all insructions that reference this global before deleting it.
Declaration
Swift
public func delete() -
Retrieves the underlying LLVM value object.
Declaration
Swift
public func asLLVM() -> LLVMValueRef
